Surgical treatment of anterior instability in rugby union players: clinical and radiographic results of the Latarjet-Patte procedure with minimum 5-year follow-up

The Latarjet Procedure for Recurrent Anterior Shoulder Instability in the Contact Athlete

In young athletes, anterior shoulder instability is a prevalent condition. Because of high-energy traumas, contact athletes often suffer recurrent instability, bone loss and postoperative recurrences. Patients younger than 20 years, symptomatic for more than 6 months, with ≥ 2 dislocations, with off-track Hill-Sachs lesion, glenoid bone loss, ALPSA lesion, Instability Severity Index Score > 3, and Glenoid Track Instability Management Score > 3 are at higher risk of failure. In cases of multiple dislocations with critical or subcritical glenoid bone loss, notably in collision and contact athletes, the Latarjet procedure is widely recognized as the treatment of choice.

Postoperative Radiographic Outcomes Following Primary Open Coracoid Transfer (Bristow-Latarjet) Vary in Definition, Classification, and Imaging Modality: A Systematic Review

PURPOSE

To analyze radiographic outcomes by conventional radiography, computed tomography (CT), or both and complication rates of open coracoid transfer at a minimum of 12-months follow-up.

METHODS

A literature search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, using PubMed, Medline (Ovid), and EMBASE library databases. Inclusion criteria were clinical studies reporting on open Latarjet as the primary surgical procedure(revision coracoid transfer after failed prior stabilization excluded) with postoperative radiographic outcomes at a minimum mean 1-year follow-up. Patient demographics, type of postoperative imaging modality, and radiographic outcomes and complications including graft union, osteoarthritis, and osteolysis were systematically reviewed. Data were summarized as ranges of reported values for each outcome metric. Each radiographic outcome was graphically represented in a Forest plot with point estimates of the incidence of radiographic outcomes with corresponding 95% confidence intervals and I2.

RESULTS

Thirty-three studies met inclusion criteria, with a total of 1,456 shoulders. The most common postoperative imaging modality was plain radiography only (n = 848 [58.2%]), both CT and radiography (n = 287 [19.7%]), and CT only (n = 321 [22.1%]). Overall, the reported graft union rate ranged from 75% to 100%, of which 79.8% (n = 395) were detected on plain radiography. The most common reported postoperative radiographic complications after the open coracoid transfer were osteoarthritis (range, 0%-100%, pooled mean 28%), graft osteolysis (range, 0%-100%, pooled mean 30%), nonunion (range, 0%-32%, pooled mean 5.1%), malpositioned graft (range, 0%-75%, pooled mean 14.75%), hardware issues (range, 0%-9.1%, pooled mean 5%), and bone block fracture (range, 0%-8%, pooled mean 2.1%). Graft healing was achieved in a majority of cases (range, 75%-100%).

CONCLUSION

Postoperative radiographic outcomes after open coracoid transfer vary greatly in definition, classification, and imaging modality of choice. Greater consistency in postoperative radiographic outcomes is essential to evaluate graft healing, osteolysis, and nonunion.

High Rates of Return to Play and Low Recurrence Rate After Arthroscopic Latarjet Procedure for Anterior Shoulder Instability in Rugby Players

Purpose

To analyze the rate of return to play, changes in athletic level, and recurrence rate and to report subjective outcomes in a series of rugby players with anterior shoulder instability who underwent an arthroscopic Latarjet procedure.

Methods

A multicenter retrospective study done in 2 centers on rugby players who were operated on between January 2011 and December 2020 was performed. Rugby players who underwent arthroscopic Latarjet procedure for anterior shoulder stabilization with a minimum follow-up period of 2 years were included. Rugby players were grouped according to their competitive level in their country (recreational, regional, national, and international). Data collected included return to sport after surgery, time to return to rugby, athletic level before and after surgery, patient satisfaction, and subjective scores. Recurrence and apprehension rates were also evaluated.

Results

A total of 73 subjects were included. Mean age at time of surgery was 23 ± 5 years. Mean duration of follow-up was 5 ± 2.6 years. Eighty-four percent of rugby players returned to rugby within a mean period of 6.6 months. Initial athletic level was a significant factor (P = .012) for not returning to sport, with 67% of patients who initially played at a recreational level not returning to rugby and 33% of patients who initially played at a regional league level not returning. All national and international players returned to play. Of the 12 non-returning rugby players, only 30% did not return because of their shoulder. Mean Subjective Shoulder Value was 90 ± 9%. Recurrence rate was 7%.

Conclusions

Arthroscopic Latarjet procedure proved its efficacy in managing recurrent anterior shoulder instability in rugby players. Return to play was achieved in almost all cases, with low recurrence rates. Despite high global return to the same level of sport, the higher the level of competition, the harder it is for rugby players to resume sport at the same level.

The open Latarjet-Patte procedure for the treatment of anterior shoulder instability in professional handball players at a mean follow-up of 6.6 years

BACKGROUND

The popularity of team handball is increasing, with >10 million children playing this overhead throwing and collision sport with highest demands on the shoulder joint. Because of the risk of recurrent instability, the Latarjet-Patte (LP) procedure has been recommended to treat young competitive players. This is the first LP outcome study in professional handball players.

METHODS

We retrospectively included 20 shoulders (18 players [17 male patients]; mean age, 22.9 years [range, 17-35 years]; minimum follow-up period, 2 years; mean follow-up period, 6.6 years) operated on by 3 expert surgeons (2011-2020) with the Walch LP technique. We documented preoperative hyperlaxity (25%, n = 5), affected throwing arm (55%, n = 11), position (backcourt, winger, and goalkeeper, 22% each; full back and pivot, 17% each), >2 dislocations prior (20%, n = 4), >10 dislocations prior (5%, n = 1), previous failed Bankart or humeral avulsion of glenohumeral ligament (HAGL) repair (10%, n = 2), and large Hill-Sachs lesions (HSLs) (20%, n = 4). Clinical and radiographic outcomes, visual analog scale score, Subjective Shoulder Value, Walch-Duplay score, Rowe score, and return-to-sport (RTS) rate were recorded.

RESULTS

The RTS rate was 85% (17 of 20 shoulders); rate of RTS at the same level, 80% (16 of 20); and rate of RTS with no throwing pain, 73% (8 of 11). The time to training with a ball was 3.2 months, and the time to competition was 4.9 months. The mean Rowe score, Walch-Duplay score, and Subjective Shoulder Value were 90 points, 88 points, and 89%, respectively. Shoulder symptoms led players to give up handball in 2 cases (10%), whereas 1 player (5%) stopped playing handball for other reasons. We recorded 1 recurrent dislocation (5%) (non-throwing arm, winger, no recurrence after rehabilitation). Persistent apprehension occurred in 1 goalkeeper (5%). Residual pain was seen in 4 shoulders (20%); this was relieved by screw removal in 1. Resistant pain (throwing shoulder) was seen in 2 backcourt players (10%, 1 of whom had a large HSL) and 1 goalkeeper (5%; large HSL with >10 dislocations prior), all 3 of whom were aged > 30 years. Bone block positioning was correct (no lateral overhang) in all shoulders. At final follow-up, 1 shoulder (5%) showed mild arthritic changes (>10 dislocations, large HSL).

CONCLUSION

The open LP procedure is consistent in providing shoulder stability combined with return-to-throwing performance in professional handball players with a short time to RTS and high same-level RTS rate without increasing the risk of arthritic changes. Throwing shoulders of backcourt players, large HSLs, or age > 30 years may have an increased risk of persistent symptoms.

Normative values for internal and external glenohumeral rotation strength in rugby players: A systematic review with meta-analysis

This systematic review aims to provide normative values for internal and external glenohumeral rotation strength in rugby players. From the inception to March 2021, the search strategy was (strength OR torque) AND shoulder AND rugby using PubMed, Scopus, Web of Science, and SPORTDiscus databases, with no language restrictions. This systematic review includes 15 articles involving 573 rugby players and presenting internal or external glenohumeral rotation strength values. Two main methods are used to assess glenohumeral rotation strength in rugby players: isokinetic and isometric methods; in the isometric method, the upper arm is abducted at either 0° or 90°. Owing to differences in isokinetic procedures and a lack of studies assessing isometric strength when the upper arm is in a neutral position, normative internal or external glenohumeral rotation strength values are only provided for isometric contractions when the upper arm is abducted at 90° based on 311 shoulders of 163 male rugby union players, with 2.04 ± 0.15 N.kg-1 and 2.11 ± 0.13 N.kg-1 for internal and external glenohumeral rotation strength, respectively. These findings may help strength and conditioning coaches and physical therapists, provide objective evidence when deciding whether or not rugby union players should return to sport.

The 50 Most Cited Papers on Rugby since 2000 Reveal a Focus Primarily on Strength and Conditioning in Elite Male Players

We sought to conduct a bibliometric analysis and review of the most cited publications relating to rugby since 2000 in order to identify topics of interest and those that warrant further investigations. Clarivate Web of Science database was used to perform a literature search using the search term "rugby." The top 200 papers by citation count were extracted and reviewed for the inclusion criteria: all subjects were rugby players. The top 50 manuscripts were included for analysis of author, publication year, country of lead authors, institution, journal name and impact factor, topic, participant sex, and level of rugby. The total number of citations was 9,071 (average of 181.4 citations/article), with an average journal impact factor of 7.21; the top article was cited 407 times at the time of analysis. The most frequent publication was the Journal of Strength and Conditioning Research (26%), followed by the British Journal of Sports Medicine (20%) and the Journal of Sports Sciences (18%). Forty-eight (96%) of the manuscripts contained only male subjects, with 1 manuscript including females only and 1 manuscript containing mixed sexes. Thirty-three (66%) of the manuscripts focused on professional rugby players, with the next highest player group being mixed levels (10%). Twenty-eight (56%) concentrated on topics regarding strength and conditioning, 11 (22%) on injury, and 4 (8%) on physiology. Despite rugby being one of the most injurious sports and community players representing the largest component of the player pool, most of the top-cited rugby articles are cohort studies of professional male athletes focused on performance and strength and conditioning, noting the bias in research towards socially relevant topics that may not impact the majority of stakeholders and long-term health of rugby athletes. These findings highlight the need for further research among women and community athletes and on topics in injury prevention.

Arthroscopic Latarjet yields better union and prevention of instability compared to arthroscopic bony Bankart repair in shoulders with recurrent anterior instability: a systematic review

PURPOSE

To determine whether arthroscopic Latarjet procedure or arthroscopic bony Bankart repair provide better outcomes in terms of rates of recurrent instability, non-union and complications, as well as clinical scores and range of motion.

METHODS

An electronic literature search was performed using PubMed, Embase®, and Cochrane databases, applying the following keywords: "Arthroscopic bony Bankart" OR "Arthroscopic osseous Bankart" AND "Arthroscopic Latarjet" OR "Arthroscopic coracoid bone block".

RESULTS

The systematic search returned 1465 records, of which 29 were included (arthroscopic bony Bankart repair, n = 16; arthroscopic Latarjet, n = 13). 37 datasets were included for data extraction, on 1483 shoulders. Compared to arthroscopic Latarjet, arthroscopic bony Bankart repair had significantly higher instability rates (0.14; CI 0.10-0.18; vs 0.04; CI 0.02-0.06), significantly lower union rates (0.63; CI 0.28-0.91 vs 0.98; CI 0.93-1.00), and significantly lower pain on VAS (0.42; CI 0.17-0.67 vs 1.17; CI 0.96-1.38). There were no significant differences in preoperative glenoid bone loss, follow-up, complication rate, ROWE score, ASES score, external rotation, and anterior forward elevation between arthroscopic Latarjet and arthroscopic bony Bankart repair.

CONCLUSION

Compared to arthroscopic Latarjet, arthroscopic bony Bankart repair results in significantly (i) higher rates of recurrent instability (14% vs 4%), (ii) lower union rates (63% vs 98%), but (iii) slightly lower pain on VAS (0.45 vs 1.17). There were no differences in complication rates, clinical scores, or postoperative ranges of motion.

The Successful Resolution of Bilateral Recurrent Shoulder Dislocation With the Bilateral Shoulder Open Latarjet Procedure: A Case Report

Recurrent shoulder dislocation is a common orthopedic condition, but bilateral involvement is rare and presents unique challenges in management. The Latarjet procedure is an effective surgical technique that addresses instability by creating a bony block on the anterior glenoid rim. This case highlights the successful management of bilateral recurrent shoulder dislocation using the bilateral shoulder open Latarjet procedure and emphasizes the importance of early intervention in such cases.

Outcomes at Long-term Follow-up After Open Latarjet Versus Open Bankart Repair in Rugby Players

Background

Because rugby is a collision sport, it exposes players to a high risk of recurrence after anterior shoulder stabilization. Therefore, the choice of surgical procedure warrants close attention in order to optimize the time to return to sport and the stability of the shoulder throughout the player's career.

Hypothesis

The open Latarjet procedure would allow for a faster return to play and provide a lower rate of recurrence than the open Bankart repair at long-term follow-up.

Study Design

Cohort study; Level of evidence, 3.

Methods

The study retrospectively enrolled 62 competitive rugby players who had undergone an anterior shoulder instability procedure and had at least 5 years of follow-up data. A total of 32 players treated with an open Bankart repair (BK group) were compared with 30 players (31 shoulders) treated with an open Latarjet procedure (LT group). Outcomes between groups were compared with the Rowe score, Walch-Duplay score, recurrence rate, and osteoarthritis evaluation on plain radiograph (Samilson classification).

Results

The recurrence rate was significantly higher at 18.8% for the BK group (mean follow-up, 6.9 ± 1.7 years) compared with 3.3% for the LT group (mean follow-up, 6.2 ± 1.4 years) (P = .04). No postoperative complications occurred in the BK group, whereas 1 infection and 1 hematoma required a second surgery in the LT group (P = .14). In the BK and LT groups, 97% and 90% of players, respectively, were able to return to rugby at the same level or higher (P = .27), at a mean time of 8 and 6.3 months, respectively (P = .03). The mean Rowe and Walch-Duplay scores were not significantly different between the groups; however, the osteoarthritis rate was significantly higher in the BK versus the LT group (68% vs 38%, respectively; P = .03); 23% of patients, all in the BK group, had Samilson grade 2 osteoarthritis.

Conclusion

The open Latarjet procedure outperformed the open Bankart procedure in terms of stability, time to return to play, and radiological outcomes at long-term follow-up in competitive rugby players.

FIXATION METHODS IN LATARJET: BIOMECHANICAL COMPARISON OF SCREW TYPES AND PLATE FIXATION

Objective

Latarjet procedure is often preferred in recurrent shoulder dislocations accompanied by glenoid bone loss. It is observed that the superiority of bone graft fixation methods is still controversial. The aim of this study is to biomechanically compare the bone graft fixation methods in the Latarjet procedure.

Methods

15 third-generation scapula bone models were divided into 3 groups. Graft was fixated in the first group with fully-threaded cortical screws of 3.5mm diameter, in the second group two 16 mm partially-threaded cannulated screws of 4.5mm diameter, and in the third group via a mini plate and screw. The hemispherical humeral head was placed on the tip of the cyclic charge device, and thus, the charge applied to the coracoid graft was homogeneous.

Results

No statistically significant difference was found between paired comparisons (p>0.05). The forces in 5 mm displacement in total vary between 502-857N. Total stiffness measurements ranged between 105 and 625; the mean value was 258.13±53.54 with no statistically significant difference by groups (p = 0.958).

Conclusion

This biomechanical study showed that there is no difference between three coracoid fixation options in terms of fixation strength. Unlike previous assumptions, plate fixation is not biomechanically superior to screw fixation. Surgeons should consider their personal preferences and experience in choosing fixation methods.

Return to Preinjury-Level Sports After Arthroscopic Latarjet for Recurrent Anterior Shoulder Instability in Professional Athletes

Background

The Latarjet procedure is recommended to treat recurrent anterior shoulder instability with glenoid bone loss. Longer return-to-sport (RTS) times have been reported after the open Latarjet when compared with the arthroscopic Latarjet.

Purpose

To assess the clinical outcomes and RTS in athletes who underwent an arthroscopic Latarjet.

Study Design

Case series; Level of evidence, 4.

Methods

This study included 46 professional athletes with recurrent anterior shoulder instability who underwent an arthroscopic Latarjet between 2010 and 2016. Patients were divided by type of sport: noncollision and nonoverhead (n = 22), collision and martial arts (n = 13), and overhead (n = 11). Sport activity was evaluated with the Kerlan-Jobe Orthopaedic Clinic (KJOC) score, Subjective Patient Outcome for Return to Sports score, and RTS time. Clinical results were evaluated by Constant-Murley score, Walch-Duplay score, and range of external and internal rotation. Complication rates, recurrence of shoulder instability, and number of revision procedures were recorded. Correlation tests were used to assess the relationship between measured parameters.

Results

The mean ± SD patient age was 27.1 ± 7.3 years, and the mean follow-up was 50.7 ± 18 months. Overall, 44 patients (95.7%) returned to their previously practiced sports, and 40 (87%) returned to their preinjury levels. The RTS time was 5 ± 1.4 months, with no significant difference among sport types. KJOC and Subjective Patient Outcome for Return to Sports scores were 95.2 ± 5.6 and 9.5 ± 1, respectively. Significant pre- to postoperative improvement was seen on the Constant-Murley score (from 54.3 ± 9.4 to 87.9 ± 8.2; P = .001) and Walch-Duplay score (from 53.7 ± 7.3 to 88.1 ± 10.7; P = .001). Mean postoperative external and internal rotation was 72.8° ± 18.6° and 81.3° ± 11.3°. Procedure-related complications occurred in 10 patients (21.7%); recurrence of shoulder instability was observed in 4 (8.7%); and 4 (8.7%) underwent revision surgery. A worse Walch-Duplay score was significantly associated with longer RTS time (r = -0.39; P = .019) and lower KJOC score (r = 0.29; P = .03).

Conclusion

There was a 95.7% RTS rate after the arthroscopic Latarjet procedure, although the procedure was not free from complications.

Open Latarjet Versus Arthroscopic Bankart Repair for the Treatment of Traumatic Anterior Shoulder Instability in High-Demand Patients With Minimal Glenoid Bone Loss

BACKGROUND

This study compared the clinical outcomes and return to sports/work between open Latarjet and arthroscopic Bankart repair in high-demand patients with traumatic anterior shoulder instability with minimal glenoid bone loss.

METHODS

We prospectively recruited 30 patients and randomised them to either open Latarjet or arthroscopic Bankart. The mean duration of follow-up in our study was 13.27 months±2.70. All patients were males with a mean age at surgery of 28.6 years (range, 18-41 years).

RESULTS

The overall mean for the Rowe score in the 30 patients increased from 33.5±14 points preoperatively to 79.6±18 points. However, there was no statistically significant difference in the postoperative ROM (range of motion) and Rowe score among the Bankart and Latarjet groups. The main finding in our study was the time to return to sports/work which was significantly lower in the Latarjet group (5.2 months) compared to the Bankart group (seven months).

CONCLUSIONS

Open Latarjet is considered a more invasive and non-anatomical procedure, however, it is less costly with a shorter time to return to sports/work compared to the Bankart procedure, which is very crucial for high-demand patients, especially the competitive athletes targeting an early return to sports at the same pre-injury level with minimal incidence of recurrence, making the surgeon's choice very challenging.

Functional Deficits After Open Latarjet Procedure and Dominance of the Operated Shoulder: An Analysis of 133 Patients

BACKGROUND

Return to sport after stabilization surgery using the open Latarjet procedure remains challenging. Additional knowledge is needed about postoperative shoulder functional deficits in order to better design return-to-sport programs.

PURPOSE

To investigate the effects of the dominance status of the operated shoulder on the shoulder functional profile recovery at 4.5 months after open Latarjet procedure.

STUDY DESIGN

Cross-sectional study; Level of evidence, 3.

METHODS

A retrospective analysis of prospectively collected data was performed. All patients who underwent the open Latarjet procedure between December 2017 and February 2021 were eligible for the study. Functional assessment at 4.5 months after the surgery was performed using the following tests: maximal voluntary isometric contractions in glenohumeral internal and external rotation, upper-quarter Y balance test, unilateral seated shot-put test, and modified closed kinetic chain upper extremity stability test, leading to 10 outcome measures. Patients whose dominant side had undergone surgery and those whose nondominant side had undergone surgery were compared with a group of 68 healthy control participants.

RESULTS

A total of 72 patients who underwent an open Latarjet procedure on the dominant side and 61 patients who underwent open Latarjet on the nondominant side were compared with 68 healthy control athletes. In patients whose dominant shoulder had undergone surgery, significant deficits for the dominant side (P < .001) and for the nondominant side (P < .001) were found in 9 of 10 functional outcome measures. Among patients whose operations were on the nondominant shoulder, significant deficits for the nondominant side (P < .001) and for the dominant side (P < .001) were found in 9 and 5 of the 10 functional outcome measures, respectively.

CONCLUSION

Regardless of dominance of the stabilized shoulder, persistent deficits in strength, stability, mobility, power, and stroke frequency were observed at 4.5 months postoperatively. Stabilization of the dominant shoulder resulted in residual surgery-related functional impairments on both sides. However, stabilization of the nondominant shoulder resulted in impairments primarily noted in the nondominant, operative shoulder.

[Chronic posttraumatic shoulder instability]

Chronic posttraumatic shoulder instability is characterized by trauma-associated, recurrent dislocations. Surgical treatment is indicated in most cases but it remains controversial how risk factors should be weighted to decide between arthroscopic Bankart repair (ABR), Latarjet or alternative procedures. Known risk factors for recurrence are patient age, hyperlaxity, sports profile and bone loss. Surgical techniques are discussed in detail. The ABR leads to high patient satisfaction and return to sports; however, in association with risk factors, recurrent dislocations are seen even several years later. Latarjet or bone block procedures lead to high patient satisfaction, sustainable stability as a revision procedure, but can also be primarily indicated for chronic instability depending on risk factors. Early complications are more frequent but of a minor nature in most cases. All techniques are known for a serious learning curve. If performed well, they do not seem to increase the risk of arthritis, which is most affected by the number of lifetime dislocations and higher energy trauma.

Arthroscopic Latarjet With Cortical Buttons Versus Open Latarjet With Screws: A Short-Term Comparative Study

BACKGROUND

The arthroscopic bone block procedure according to Latarjet remains a controversial subject, and few comparative studies have demonstrated the benefit of arthroscopy over open surgery.

PURPOSE/HYPOTHESIS

The objective of this study was to compare both procedures by analyzing the short-term clinical results. The hypothesis was that the arthroscopic procedure is superior to the standard open procedure.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHOD

This was a retrospective comparative study. Patients treated for chronic anterior instability by arthroscopic Latarjet with double cortical buttons (group A) or open Latarjet with screws (group O) with a minimum follow-up of 12 months were included. Intraoperative (duration, complications) and postoperative (complications, pain, mobility, functional scores, resumption of sport, Patient and Observer Scar Assessment Scale scar aesthetics, satisfaction) data were compared.

RESULTS

In total, 50 patients were included (n = 24 in group A, n = 26 in group O). Operating time was longer in group A (103 vs 61 min; P = .001). The average number of days on analgesics was higher in group A (8.9 vs 5.3 days; P = .04). The complication rate was similar for the 2 groups (12.5% vs 27%; P = .46). At 3 months, the loss of external rotation was greater in group A (-33° vs -18°; P = .01), and resumption of sports was less frequent (11% vs 48%; P = .01). At 12 months, the average scores were excellent, with no significants differences between the 2 groups: Walch-Duplay average, 90 points; Rowe, 94 points; Subjective Shoulder Value (SSV), 92.5%; sport SSV, 85%; and Patient and Observer Scar Assessment Scale score, 17.2 points.

CONCLUSION

Over the short term, this comparative study did not prove the superiority of the cortical-button arthroscopic Latarjet procedure over the open Latarjet procedure. A delay in the resumption of sports, longer time to recover range of motion, and no benefit regarding postoperative pain or the aesthetic aspect of the scar were observed in this study with the arthroscopic procedure.

Glenoid bone augmentation: a contemporary and comprehensive systematic review of open procedures

Introduction

There is a trend towards arthroscopically treating shoulder instability with glenoid deficiency. Despite this, there remains the option for treatment through an open technique. Multiple bone augmentation options are available for recurrent anterior shoulder instability.

Objective

To provide a systematic review of recent studies for recurrent anterior shoulder instability necessitating glenoid bone augmentation specifically through open procedures using coracoid bone or free bone blocks [iliac crest bone autograft/allograft or distal tibia allograft (DTA)].

Methods

PubMed, Cochrane, EMBASE, and Google Scholar were searched for studies reporting open glenoid bone augmentation procedures with iliac crest, tibia, or coracoid bones within 10 years. Extracted data included study/patient characteristics, techniques, prior surgeries, prior dislocations, radiographic findings, range of motion (ROM), recurrent instability, patient-reported outcomes, and complications.

Results

92 met inclusion criteria (5693 total patients). Six were studies of iliac crest bone, four of DTA, and 84 using the coracoid bone. 29 studies measured postoperative arthritis showing no development or mild arthritis. 26 studies reported postoperative graft position. 62 studies reported ROM noting decline in internal/external rotation. 87 studies measured postoperative instability with low rates. Rowe Scores with noted improvement across 31/59 (52.5%) studies were seen. Common post operative complications included infection, hematoma, graft fracture, nerve injury, pain, and screw-related irritation.

Conclusion

Despite a trend towards arthroscopic management of recurrent anterior shoulder instability with glenoid deficiency, open procedures continue to provide satisfactory outcomes. Additionally, studies have demonstrated safe and efficacious use of free bone block graft options in the primary and revision setting.

Use of Cannulated Screws for Primary Latarjet Procedures

Background

Rapid consolidation of the bone block is paramount for the success of the Latarjet procedure. Noncannulated screws have shown satisfactory long-term bone block fusion, while cannulated screws are challenged with inferior mechanical properties and fusion rates.

Purpose

To report outcomes of the Latarjet procedure using cannulated screws, notably bone block fusion and complication rates at 3 months, as well as clinical scores and return to sports at minimum 2 years postoperatively.

Study Design

Case series; Level of evidence, 4.

Methods

We reviewed the records of 124 consecutive patients (124 shoulders) who underwent primary Latarjet procedures using cannulated screws between 2015 and 2018. All patients underwent clinical examination at 3 months postoperatively, including range of motion and radiographs to assess graft fusion. The Walch-Duplay score, Rowe score, Subjective Shoulder Value, and visual analog scale for pain were collected at a minimum follow-up of 2 years.

Results

Overall, 9 patients (7%) required reoperation: 7 (6%) had screw removal for unexplained residual pain, 1 (0.8%) had lavage for deep infection, and 1 (0.8%) had evacuation to treat a hematoma. Furthermore, 3 patients (2.4%) had recurrent instability, none of whom underwent reoperation. At 3-month follow-up, all 124 shoulders showed complete radiographic graft fusion, and at 40 ± 11 months (mean ± SD; range, 24-64 months), 88% of patients had returned to sport (109/124), the Walch-Duplay score was 86 ± 14, Rowe was 84 ± 15, Subjective Shoulder Value was 88 ± 11, and visual analog scale for pain was 1 ± 1.

Conclusion

The clinical relevance of these findings is that 4.5-mm cannulated screws are safe and effective for primary Latarjet procedures and grant adequate graft healing, with low recurrence of instability and a high rate of return to sports.

Low grade of osteoarthritis development after Latarjet procedure with a minimum 5 years of follow-up: a systematic review and pooled analysis

PURPOSE

The purpose of this systematic review and pooled analysis was to evaluate incidence and risk factors for glenohumeral osteoarthritis (OA) in patients who underwent Latarjet procedure with a minimum of 5-year follow-up.

METHODS

The PRISMA guidelines were followed to perform this systematic review. PubMed and EMBASE were searched up to February 29, 2020 for English, human in vivo studies that evaluated glenohumeral OA in patients undergoing Latarjet procedure at least 5 years after surgery. A pooled analysis on the included databases sent by authors was performed to evaluate the risk factors influencing the development or progression of dislocation arthropathy after the Latarjet procedure.

RESULTS

Four studies, including a total of 280 patients (213 males and 67 females), were analysed. In our study population, the median age at surgery was 25.0 years (range 20.8-32.6 years). and 92.1% were athletes. In 90% of the cases, the number of dislocations before surgery were fewer than 5. The recurrence of instability after Latarjet procedure was observed only in seven patients (2.5%). The position of the bone graft resulted flush to the anterior glenoid rim in 238 cases (85.3%), medial in 8 (2.9%) and overhanging in 33 (11.8%). Radiological signs of development or progression of shoulder OA were observed in 25.8% of the patients, of which 88.6% presented a grade 1 of OA according to Samilson and Prieto classification. The overhanging position of the bone graft resulted statistically significant for onset or worsening of OA. The age at surgery, the number of dislocations before surgery and the Hill-Sachs lesion were not significantly associated with joint degeneration. Instead, hyperlaxity showed a prevention role in the development of OA after open Latarjet procedure.

CONCLUSION

The Latarjet procedure is a valid and safe surgical treatment in recurrent anterior shoulder instability with a low risk of developing moderate or severe OA also at long-term follow-up. The overhanging position of the bone graft represents the principal risk factor of joint degeneration, whereas the hyperlaxity seems to be protective. Finally, age, gender, time between first dislocation and surgery, and number of dislocations do not seem to affect the onset of OA after Latarjet procedure. Therefore, an accurate execution of the Latarjet procedure can be considered a valid treatment even in young and athletes thanks to the low recurrence rates and the low development of major long-term complications.

Surgical treatment of anterior shoulder instability with glenoid bone loss with the Latarjet procedure in active-duty military service members

INTRODUCTION

The arthroscopic Bankart repair in the setting of glenoid bone loss has high rates of failure. In patients with anterior glenoid bone loss, the Latarjet provides glenohumeral stability through restoration of the glenoid bone, the conjoint tendon acting as a sling on the subscapularis, and anterior capsulolabral repair. Active-duty military personnel are at high risk for glenohumeral instability and have been equated to the contact athlete; most are young, male, and engage in contact sports. The purpose of this study is to assess the return to full-duty rates in active-duty military personnel following the Latarjet for anterior glenohumeral instability with glenoid bone loss.

METHODS

A retrospective review of all glenohumeral instability procedures were reviewed at a tertiary training hospital from June 2014 to June 2019. The patient population consisted of active-duty military personnel with glenoid bone loss and anterior glenohumeral instability, who were treated with a Latarjet. The primary outcome was return to full-duty status.

RESULTS

There were 50 patients identified for the study. Four patients were lost to follow-up, leaving 46 of 50 patients (92.0%) eligible for this study. The average age at the time of the index procedure was 23.1 years. The average percentage bone loss was 18.4%. Forty-one patients (89.1%) were able to return to full-duty status. Four patients (8.7%) sustained a recurrent dislocation following the Latarjet; all 4 dislocations occurred during a combat deployment. Four patients (8.7%) reported episodes of subluxation without dislocation. Forty-one patients (89.1%) reported that their shoulders felt stable, and we found an average return to full duty at 5.3 months CONCLUSION: In our active-duty military cohort, we found an 8.7% rate of recurrent instability after a Latarjet procedure, and 41 patients (89.1%) were able to return to full-duty status. In conclusion, the Latarjet procedure in the active-duty military population with anterior glenoid bone loss resulted in a high rate of return to duty, excellent functional outcomes, low rate of recurrent instability, and a low overall complication rate.

Anterior Shoulder Instability Part II-Latarjet, Remplissage, and Glenoid Bone-Grafting-An International Consensus Statement

PURPOSE

The purpose of this study was to establish consensus statements via a modified Delphi process on the Latarjet procedure, remplissage, and glenoid-bone grafting for anterior shoulder instability.

METHODS

A consensus process on the treatment utilizing a modified Delphi technique was conducted, with 65 shoulder surgeons from 14 countries across 5 continents participating. Experts were assigned to one of 9 working groups defined by specific subtopics of interest within anterior shoulder instability.

RESULTS

The technical approaches identified in the statements on the Latarjet procedure and glenoid bone-graft were that a subscapularis split approach should be utilized, and that it is unclear whether a capsular repair is routinely required. Furthermore, despite similar indications, glenoid bone-grafting may be preferred over the Latarjet in patients with bone-loss greater than can be treated with a coracoid graft, and in cases of surgeon preference, failed prior Latarjet or glenoid bone-grafting procedure, and epilepsy. In contrast, the primary indications for a remplissage procedure was either an off-track or engaging Hill-Sachs lesion without severe glenoid bone loss. Additionally, in contrast to the bone-block procedure, complications following remplissage are rare, and loss of shoulder external rotation can be minimized by performing the tenodesis via the safe-zone and not over medializing the fixation.

CONCLUSION

Overall, 89% of statements reached unanimous or strong consensus. The statements that reached unanimous consensus were the prognostic factors that are important to consider in those undergoing a glenoid bone-grafting procedure including age, activity level, Hill-Sachs Lesion, extent of glenoid bone-loss, hyperlaxity, prior surgeries, and arthritic changes. Furthermore, there was unanimous agreement that it is unclear whether a capsular repair is routinely required with a glenoid bone graft, but it may be beneficial in some cases. There was no unanimous agreement on any aspect related to the Latarjet procedure or Remplissage.

Intra-articular Versus Extra-articular Coracoid Grafts: A Systematic Review of Capsular Repair Techniques During the Latarjet Procedure

Background:

Various methods exist for managing the joint capsule during the Latarjet procedure. Repairing the capsule to the native glenoid rim results in an extra-articular bone block, while repairing it to the remnant coracoacromial ligament stump of the coracoid graft renders it intra-articular. The technique that optimizes patient outcomes is not well defined.

Purpose:

To compare the outcomes of intra-articular and extra-articular bone block techniques for the Latarjet procedure.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

Using PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) guidelines, we queried the PubMed, EMBASE, and the Cochrane Library for all studies reporting outcomes of the Latarjet procedure with a clearly defined method of capsular repair that rendered the coracoid graft intra-articular or extra-articular. The included levels of evidence and degree of heterogeneity in this study precluded meta-analysis. Outcomes of interest included preoperative variables, surgical technique, rehabilitation protocols, functional outcome assessments, recurrent instability, range of motion, and radiographic findings.

Results:

A total of 16 studies including 816 patients were included. A total of 8 studies employed an intra-articular bone block in 338 patients, while the other 8 employed an extra-articular technique in 478 patients. There was variation among studies in reference to baseline patient characteristics, surgical techniques, rehabilitation, methods for assessing patient outcomes, and follow-up times. Rates of postoperative instability were reported in 8 intra-articular (0%, 0%, 2.1%, 2.7%, 3.2%, 5%, 5.4%, 5.9%) and 7 extra-articular (0%, 0%, 1.2%, 2%, 3.9%, 6.3%, 14%) bone block studies. Postoperative osteoarthritis or progression of preoperative osteoarthritis was reported in 5 intra-articular bone block studies (0%, 5.6%, 23.5%, 23.5%, 25%) and 4 extra-articular bone block studies (0%, 1.9%, 5.2%, 8.6%).

Conclusion:

Varying capsular repair methods appeared to provide similar outcomes regarding stability. There was an apparent trend toward higher rates of post-traumatic arthritis among studies in which an intra-articular bone block technique was employed; however, it is possible that this was influenced by substantially different follow-up times between groups and other various sources of heterogeneity among the included studies. There were no studies in the literature directly comparing intra-articular and extra-articular bone block techniques. Large-scale randomized controlled trials or comparative studies are needed to draw stronger conclusions comparing the 2 techniques.

RESULT OF BONE BLOCKING SURGERY IN COMBAT ATHLETES WITH ANTERIOR SHOULDER INSTABILITY: A PROSPECTIVE STUDY

Objective:

This study aims to understand the way fighting athletes respond to bone block surgery in the treatment for shoulder instability.

Methods:

Prospective clinical study with competitive fighters with shoulder instability who underwent bone block surgery from 2013 to 2016, followed by a postoperative rehabilitation protocol. For the evaluation, eight combat athletes with anterior shoulder instability were treated, with a total of nine shoulders, since one athlete underwent bilateral surgery. All patients signed the Free and Informed Consent Form. The evaluation protocol included medical consultation, radiography of the operated shoulder, degree of active and passive lateral rotation; degree of active and passive elevation; visual analogue scale (VAS) for pain; Athletic Shoulder Outcome Rating Scale (EROE; acronym in Portuguese) scores; Western Ontario Shoulder Instability Index (WOSI), and American Shoulder and Elbow Surgeons (ASES).

Results:

We observed a decrease in the range of passive and active movement in the recent postoperative period. In later postoperative, values were close to those in the preoperative period at the end of the follow-up. There was improvement in pain, and in all ASES, WOSI and EROE scores no complications were documented. As for returning to sport, two athletes did not return, one of them due to shoulder pain and the other due to retirement.

Conclusion:

Bone block surgery has shown good functional results in uncomplicated combat athletes. Level of Evidence IV, Prospective Case Series.

Both Open and Arthroscopic Latarjet Result in Excellent Outcomes and Low Recurrence Rates for Anterior Shoulder Instability

Purpose

The purpose of this study is to evaluate the patient-reported outcomes of open Latarjet (OL) compared to arthroscopic Latarjet (AL) for anterior shoulder instability.

Methods

A retrospective review of patients who underwent either OL or AL for anterior shoulder instability between 2011 and 2019 was performed. Recurrent instability, visual analog scale (VAS) score, Shoulder Instability-Return to Sport after Injury (SIRSI), Subjective Shoulder Value (SSV), Western Ontario Shoulder Instability (WOSI) score, patient satisfaction, willingness to undergo surgery again, and return to work/sport (RTW/RTS) were evaluated. A P value of < .05 was considered to be statistically significant.

Results

Our study included 102 patients in total; 72 patients treated with OL, and 30 treated with AL. There were no demographic differences between the two groups (P > .05 for all). At final follow up (mean of 51.3 months), there was no difference between those that underwent OL or AL in the reported WOSI, VAS, VAS during sports, SSV, and SIRSI scores, nor in patient satisfaction, or whether they would undergo surgery again (P > .05). Overall, there was no significant difference in the total rate of RTP (65% vs 60.9%; P = .74), or timing of RTP (8.1 months vs 7 months; P = .35). Additionally, there was no significant difference in the total rate of RTW (93.5% vs 95.5%; P = .75). Overall, 3 patients in the OL group and 2 patients in the AL group had recurrent instability events (6.9% vs 6.7%; P = .96), with no significant difference in the rate of recurrent dislocation (4.2% vs 3.3%; P = .84).

Conclusion

In patients with anterior shoulder instability, both the OL and AL are reliable treatment options, with a low rate of recurrent instability, and similar patient-reported outcomes.

Clinical outcomes of Gaelic Athletic Association athletes after surgical stabilization in the setting of anterior shoulder instability

Background

Gaelic Athletic Association (GAA) games are collision sports played at an amateur level, which represent the most popular sports played on the island of Ireland. Each year, many GAA players in Ireland require surgical stabilization with either arthroscopic Bankart repair (ABR) or open Latarjet (OL) procedures in the setting of anterior shoulder instability. The purpose of this study was to evaluate the clinical outcomes, recurrence, and return to play (RTP) in athletes who play GAA games having undergone surgical stabilization with either ABR or OL procedures in the setting of anterior shoulder instability.

Methods

A retrospective review of all patients with anterior shoulder instability whom had stabilization with either ABR or OL under a single surgeon between 2012 and 2018 was performed. Patients who were athletes partaking in GAA sports were followed up by chart review and telephone survey to assess their clinical outcomes including satisfaction, pain as measured on the visual analog scale score, the Subjective Shoulder Value, recurrence, complications, and revision surgeries. In addition, RTP rates, time to RTP, level of RTP, and Shoulder Instability–Return to Sport after Injury scores were evaluated.

Results

A total of 200 GAA athletes (194 males) with a mean age of 23.9 ± 6.1 years with mean follow-up of 50.4 ± 24 months were included in this study. A total of 98.1% patients were satisfied with their procedure at the latest follow-up, with an overall recurrence rate of 5%. A total of 6.5% of athletes required revision surgery, of whom 4% required revision stabilization (all of whom had recurrence). The overall rate of RTP was 88% at mean 6.0 ± 1.7 months postoperatively, with 75% of athletes returning at the same or higher levels than their preinjury level. There were no significant differences for all outcome measures analyzed between patients who had ABR or OL procedures.

Conclusion

GAA athletes with anterior shoulder instability treated with either ABR or OL procedures report excellent clinical outcomes at medium-term follow-up, with high satisfaction rates, excellent functional outcomes, and high rates of RTP. Furthermore, this cohort demonstrates low rates of recurrence after stabilization with few requiring revision surgery.

Intra-articular biomechanical environment following modified Bristow and Latarjet procedures in shoulders with large glenoid defects: relationship with postoperative complications

BACKGROUND

Although coracoid transfers including the modified Bristow and Latarjet procedures are widely used to treat anterior shoulder instability, the influence of the choice of procedure on the biomechanical outcomes is not well characterized. We aimed to clarify the intra-articular stress distribution following these 2 procedures using 3-dimensional finite-element analysis and to investigate the role of stress distribution in the pathophysiology of postoperative complications.

METHODS

Overall, 6 male patients aged 17-47 years with unilateral anterior shoulder instability were recruited. Computed tomographic digital imaging and communications in medicine (CT-DICOM) data of the contralateral (healthy) shoulder of each patient was obtained and used for developing the 3-dimensional normal glenohumeral joint model. A 25% bony defect was created in the anterior glenoid rim where the coracoid process was transferred in the standing and lying-down positions to create the Bristow and Latarjet models, respectively. The arm position was set as 0° or 90° abduction. The Young moduli of the humerus and scapula were calculated using CT data, and set as 35.0 MPa and 113.8 GPa for the articular cartilage and inserted screw, respectively. A compressive load (50 N) was applied to the greater tuberosity toward the center of the glenoid, and a tensile load (20 N) was applied to the tip of the coracoid in the direction of conjoint tendon. Elastic analysis was used to determine the equivalent stress distribution.

RESULTS

A significant reduction in mean equivalent stress was observed within the glenoid cartilage for both models (P = .031); however, a new stress concentration appeared within the grafted coracoid-facing region of the humeral-head cartilage in both models. The proximal half of the coracoid graft exhibited lower equivalent stress than the distal half in 5 of the 6 Latarjet models, whereas the proximal half showed higher equivalent stress than the distal half in all 6 Bristow models. High stress concentration was identified at the midpoint of the inserted screw in Bristow models.

DISCUSSION AND CONCLUSIONS

Intra-articular stress distribution may explain the different rates of postoperative complications associated with the modified Bristow and Latarjet procedures. New stress concentration within the humeral-head cartilage might contribute to the development of glenohumeral osteoarthritis following both procedures. Stress shielding in the proximal part of the coracoid graft might contribute to osteolysis following the Latarjet procedure. Surgeons should be aware of the risk of breakage of the inserted screw following the modified Bristow procedure.

Return to Professional Australian Rules Football After Surgery for Traumatic Anterior Shoulder Instability

BACKGROUND

The treatment of traumatic anterior shoulder instability in professional Australian Football League (AFL) players is challenging, with an emphasis on early return to play and avoidance of instability recurrence.

PURPOSE

To investigate return-to-sport (RTS) outcomes and complications after 2 different procedures for traumatic anterior shoulder instability in professional AFL players.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

We retrospectively reviewed our surgical database for professional AFL players who underwent capsulolabral stabilization or open Latarjet procedure by a single surgeon between 2006 and 2017. Outcomes included RTS, on-field performance, and complications. Between-group analyses for RTS and complications were estimated using Kaplan-Meier survival analyses. Within-group analyses for on-field performance data were performed using paired t tests with significance set at .05.

RESULTS

A total of 58 capsulolabral stabilization procedures in 54 players and 32 Latarjet procedures in 29 players were included in the analysis; 93.1% of capsulolabral patients and 96.9% of Latarjet patients returned to professional AFL. The median RTS time was 6.8 months for the capsulolabral group and 7.3 months for the Latarjet group. There was no significant difference in RTS rates between the 2 groups (P = .270). Of those undergoing surgery early in the season, 75% of the capsulolabral and 71% of Latarjet group were able to RTS within the same season, at a mean time of 16.9 weeks and 18.8 weeks, respectively. There was a significant difference in instability recurrence, with 19% for the capsulolabral group and no recurrence in the Latarjet group (P = .017). There was no significant reduction in player on-field performance in either group (P < .05).

CONCLUSION

In this study, the median RTS in AFL players was approximately 7 months after capsulolabral and Latarjet surgery with no compromise to on-field performance. Instability-related complications occurred only in the capsulolabral group, and the incidence increased with time.

Return to play protocols for musculoskeletal upper and lower limb injuries in tackle-collision team sports: A systematic review

Athletes in tackle-collision teams are at high risk of musculoskeletal injuries resulting in absence from play due to the high impact nature of the sport. There is a paucity of research to guide the management and assessment methods needed to facilitate the return to play (RTP) process. This review aimed to describe, synthesise and evaluate RTP protocols implemented for musculoskeletal injuries in tackle-collision teams. A systematic search of Scopus, PubMed, Web of Science and Ebsco Host was conducted for RTP management protocols and assessment modalities following upper and lower limb musculoskeletal injuries in tackle-collision team athletes. Prospective and retrospective quantitative controlled trials, cohort, case-control, case-series and cross-sectional observation studies published between January 2000 and March 2020 were considered. The main outcome measures were the proportion of athletes to RTP, associated time-loss and reinjury risk. 5265 articles were screened. 34 studies met the eligibility criteria of which 23 involved management and 11 assessment modalities. Management involved surgical or conservative strategies along with exercise-based rehabilitation. Assessment modalities included radiographic assessment, clinical evaluation and subjective ratings. Promising RTP management included progressive weight-bearing and exercised-based rehabilitation for ankle sprains as well as surgery, the use of a sling and exercise-based rehabilitation for shoulder instability. MRI scans showed promise in predicting time-loss following hamstring and calf strains in tackle-collision athletes. There are currently no clear guidelines for RTP after musculoskeletal injuries in tackle-collision sports. Future research should investigate efficient management strategies evaluated through valid and reliable assessment methods to better guide clinicians.

Low rate of recurrent instability following the open Latarjet procedure as a revision procedure for failed prior stabilization surgery

PURPOSE

The purpose of this study is to systematically review the literature to ascertain functional outcomes, recurrence rates and subsequent revision rates following the open Latarjet procedure when performed as a revision procedure.

METHODS

Two independent reviewers performed the literature search based on PRISMA guidelines, utilizing the EMBASE, MEDLINE, and The Cochrane Library Databases. Studies where the Latarjet procedure was performed as a revision procedure were included. Clinical outcomes analyzed were: (1) functional outcomes, (2) recurrent instability, (3) revisions, and (4) complications.

RESULTS

The review found 16 studies with 713 shoulders that met the inclusion criteria. 605 of the patients were male (84.9%), with an average age of 28.2 years (15-62) and follow-up of 47.7 months. The most commonly reported functional outcome measure was the Rowe score, with a weighted mean of 92.7. 86/95 patients had good-excellent outcomes (90.4%). 136/143 patients reported return to play (95.1%). 141/161 patients returned to the same level of competition (87.6%). 50 patients experienced recurrence (8.4%). Five patients experienced redislocation (0.9%) and 37 patients experienced subluxation (6.7%). There were 29 revisions (5.1%), with 12 revisions due to recurrence (2.1%). There were 68 total complications, not including recurrence (11%). The most common complications were 13 cases of nerve damage and infection respectively (2.1%). There was 17 cases of new instability arthropathy (6.5%), and 31 cases of residual pain (6.7%).

CONCLUSION

This review shows that the revision Latarjet provides excellent functional outcomes, low rates of recurrence and complications, and a high rate of return to sport among athletes. This results from study can be used to explain the expected outcomes associated with the Latarjet procedure performed as a revision.

No difference in 90-day complication rate following open versus arthroscopic Latarjet procedure

The purpose of this study was to compare the 90-day complication rate between the open and arthroscopic Latarjet procedure. A retrospective review of patients who underwent an open or arthroscopic Latarjet procedure at NYU Langone Health between 2012 and 2019 was performed. The complications, readmissions, and reoperations within 90 days were assessed. Outcomes were compared between the two approaches, and a p value of < 0.05 was considered to be statistically significant. The study included 150 patients (open: 110; arthroscopic: 40), with no patients lost to follow-up within the first 90 days. Both cohorts were similar in terms of patient demographics. No intra-operative complications were observed in either group. Overall, there were 4 post-operative complications with the open approach and 2 with the arthroscopic approach (3.6% and 5.0%, respectively; n.s.) during the study period. Three patients required a readmission within the 90-day period; one patient in both groups required a revision Latarjet for graft fracture, and one patient in the open Latarjet required irrigation and debridement for deep infection (n.s.). With the open approach, there were 2 (2.3%) wound complications, 1 graft complication, and 1 (1.1%) nerve injury. With the arthroscopic approach, there was 1 (2.8%) wound complication and 1 (2.8%) hardware complication. The safety, and 90-day complication and readmission profile of arthroscopic Latarjet is similar to open Latarjet procedure. LEVEL OF EVIDENCE: Level III.

A gender-based comparison of coracoid and glenoid anatomy: CT analysis and discussion of potential impact on the Latarjet procedure

BACKGROUND

The success of the modified Latarjet procedure depends on proper sizing of the coracoid graft. There is no information available regarding the morphometric relationship between the glenoid cavity and the coracoid process for the South African population. This study aims at measuring the relationship between the glenoid and coracoid morphometries and investigates their gender-related differences.

METHODS

Glenohumeral computerized tomography scans of 100 consecutive patients were considered for this study. Morphometric measurements were performed after aligning the coracoid and glenoid in their optimum orientation. These measurements were performed by 2 independent observers. The ratio between glenoid and coracoid measurements was calculated and statistically compared using the Mann-Whitney U test. Intraclass correlation coefficients were calculated to analyze interobserver reliability. All the statistical tests were performed in SPSS v.26, and power calculations in G∗Power v.3.1.

RESULTS

An average intraclass correlation coefficient value of 0.79 suggested that the interobserver reliability was good. Except for coracoid length, statistically significant (P < .05) gender differences were observed for all the other morphometries. The coracoid width (16.5 ± 1.4 mm vs. 14.7 ± 1.4 mm) and height (13.6 ± 1.6 mm vs. 10.5 ± 1.5 mm) differed between genders by 1.8 and 3.1 mm, respectively. The glenoid anteroposterior (AP) (25.3 ± 2.9 mm vs. 23.2 ± 2.4 mm) and superioinferior (36.9 ± 1.9 mm vs. 33.7 ± 2.6 mm) measurements differed by 2.1 and 3.3 mm, respectively, between the males and the females. The ratio between the AP width of the glenoid and the coracoid height was also found to be significantly different (P < .05) between the gender groups. These morphometric ratios for the coracoid width (0.66 ± 0.09 mm vs. 0.64 ± 0.08 mm) and the coracoid height (0.55 ± 0.09 mm vs. 0.46 ± 0.07 mm) differed between genders by 0.02 and 0.09, respectively.

CONCLUSION

Measurements taken from computerized tomography scans showed significant differences between genders in absolute measurements and in the ratio of the coracoid height to the glenoid AP distance. This could have implications on the ability of the Latarjet procedure to compensate for bone loss in female patients.

Failed Latarjet procedure: a systematic review of surgery revision options

Background

Revision surgery after the Latarjet procedure is a rare and challenging surgical problem, and various bony or capsular procedures have been proposed. This systematic review examines clinical and radiographic outcomes of different procedures for treating persistent pain or recurrent instability after a Latarjet procedure.

Methods

A systematic review of the literature was performed using the Medline, Cochrane, EMBASE, Google Scholar and Ovid databases with the combined keywords “failed”, “failure”, “revision”, “Latarjet”, “shoulder stabilization” and “shoulder instability” to identify articles published in English that deal with failed Latarjet procedures.

Results

A total of 11 studies (five retrospective and six case series investigations), all published between 2008 and 2020, fulfilled our inclusion criteria. For the study, 253 patients (254 shoulders, 79.8% male) with a mean age of 29.6 years (range: 16–54 years) were reviewed at an average follow-up of 51.5 months (range: 24–208 months).

Conclusions

Eden–Hybinette and arthroscopic capsuloplasty are the most popular and safe procedures to treat recurrent instability after a failed Latarjet procedure, and yield reasonable clinical outcomes. A bone graft procedure and capsuloplasty were proposed but there was no clear consensus on their efficacy and indication.

Recurrence and return to sport after surgery for shoulder instability: arthroscopic Bankart versus Latarjet procedure

Background

Surgeons differ in their preferences concerning the best surgical technique for treating shoulder instability in sportspeople. The purpose was to evaluate the risk of recurrence and the likelihood of return to sport for the 2 principal shoulder stabilization techniques used to treat shoulder instability in sportspeople.

Methods

We screened sportspeople who had undergone shoulder stabilization for inclusion in this cohort study. For eligibility, patients had to have undergone surgery by one of the 2 techniques: Latarjet or arthroscopic Bankart between 2005 and 2011, and aged from 18 to 35 years. We excluded acromioclavicular dislocation, tendinous lesion, global or posterior instability, bone fracture or severe glenoid bone loss, neurological lesion, other surgical technique, and orthopedic treatment. Patients were contacted by telephone between 2009 and 2012 and asked to participate in follow-up after surgery. The primary endpoint was recurrence, evaluated by determining frequency and time to recurrence (or censoring) with Cox models. The secondary endpoint was the return to sport (training and competition).

Results

Follow-up telephone interviews were conducted with 120 sportspeople (response rate of 61.5%), one of whom was excluded due to the occurrence of a new contralateral dislocation before returning to sport after surgery (Latarjet n = 80, Bankart n = 39). The risk of recurrence was significantly higher (P < .001) for Bankart (n = 7, 17.9%) than for Latarjet (n = 2, 2.5%) interventions. Being under the age of 20 years was a significant risk factor for recurrence (P = .007). Return to sport was significantly more frequent among sportspeople undergoing Latarjet procedures, for both training (P = .031) and competition (P = .038), and was also significantly more rapid for training (P = .034) with a mean time to return to training of 5.1 months for Latarjet procedures, versus 6.4 months for Bankart procedures.

Conclusion

The Latarjet surgical technique results in fewer recurrences than the Bankart technique, with a higher rate of return to sport (training, competition) and a faster return to training for sportspeople practicing potentially risky sports in competition. Age was also identified as an additional risk factor for recurrence. It is important to take these factors into account when considering the indications for surgery.

Arthroscopic Soft Tissue Stabilization With Selective Augmentations for Traumatic Anterior Shoulder Instability in Competitive Collision Athletes

BACKGROUND

Many surgeons prefer bony stabilization including Bristow or Latarjet procedures for shoulder instability in collision athletes, even though several potential complications have been reported. There has been a limited number of studies on the midterm outcomes of arthroscopic soft tissue stabilization for anterior shoulder instability in competitive collision athletes.

PURPOSE

To assess the outcomes of arthroscopic soft tissue stabilization in combination with selective augmentation procedures for collision athletes with traumatic anterior shoulder instability.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

We retrospectively assessed rugby or American football players (<40 years old) who underwent arthroscopic Bankart or bony Bankart repair with selective augmentations (rotator interval closure and/or Hill-Sachs remplissage) for traumatic anterior shoulder instability between January 2012 and March 2017. Shoulders that required other bony procedures were excluded. Recurrence, complications, return to sport, and functional scores (Rowe score and Subjective Shoulder Value sports score) were investigated.

RESULTS

This study included 113 shoulders in 100 patients with a mean age of 20 years (range, 15-36 years) at surgery. Rotator interval closure was performed on 36 shoulders in addition to Bankart repair, and rotator interval closure and Hill-Sachs remplissage were performed on 77 shoulders. The mean follow-up period was 44 months (range, 24-72 months). Of the 113 shoulders, 4 (3.5%) experienced postoperative dislocation, but there were no complications. A total of 93 athletes (93%) attained complete or near complete preinjury sports activity levels. The mean Rowe score significantly improved from 36 (range, 10-75) at presurgery to 96 (range, 35-100; P = .003) at postsurgery. The mean Subjective Shoulder Value sports score significantly improved after surgery, from a mean preoperative score of 22 (range, 0-50) to a postoperative score of 92 (range, 64-100; P = .002).

CONCLUSION

Our treatment strategy, where arthroscopic soft tissue stabilization was combined with selected augmentations, provided good clinical outcomes for competitive collision athletes in terms of low rates of recurrence and complication, a high rate of return to sports, and good shoulder function.

Shoulder and elbow pathology in the female athlete: sex-specific considerations

Unique biologic and biomechanical aspects of the female body make women more prone to certain orthopedic injuries. Sex differences are well understood with regard to certain orthopedic pathologies such as anterior cruciate ligament injury, hallux valgus, carpal tunnel, and carpometacarpal joint arthritis; however, sex differences are less commonly discussed with regard to shoulder and elbow pathology. The purpose of this review is to elucidate sex differences specific to sports-related shoulder and elbow injuries in the female athlete population.

The S-STARTS Test: Validation of a Composite Test for the Assessment of Readiness to Return to Sport After Shoulder Stabilization Surgery

BACKGROUND

The time elapsed since surgery is the primary criterion for allowing athletes to return to sport after shoulder stabilization surgery using the Latarjet procedure. The objective assessment of shoulder functional status through the return-to-sport continuum demands a scoring instrument that includes psychological and physical dimensions. This study aimed to statistically validate the Shoulder-SanTy Athletic Return To Sport (S-STARTS) score in patients who have undergone primary shoulder stabilization surgery.

HYPOTHESIS

The S-STARTS score fulfils the criteria for statistical validation for assessing return-to-sport readiness after shoulder stabilization surgery.

STUDY DESIGN

Diagnostic study.

LEVEL OF EVIDENCE

Level 4.

METHODS

Fifty patients and 50 controls completed the Shoulder Instability-Return to Sport after Injury questionnaire and performed 4 physical performance tests, from which 8 outcome measures were extracted to provide a composite score, named S-STARTS, according to a scoring procedure. The statistical validation of the S-STARTS score was based on construct validity, discriminant validity, sensitivity to change, internal consistency, reliability, agreement, and feasibility.

RESULTS

The 8 components of the S-STARTS score provided additional information (0.01 ≤ |r| ≤ 0.59). The S-STARTS score exhibited good reliability (intraclass coefficient of correlation [3,k] = 0.74), no ceiling or floor effects, and high discrimination and sensitivity to change. The S-STARTS score was significantly lower in patients than in controls (13.5 ± 3.8 points vs 16.1 ± 2.7 points, respectively; P < 0.001). A significant increase was reported between 4.5 and 6.5 months postoperatively (12.8 ± 2.3 points vs 17.2 ± 2.4 points, respectively; P < 0.001).

CONCLUSIONS

The S-STARTS score meets statistical validation criteria for the assessment of shoulder functional status after shoulder stabilization surgery using the Latarjet procedure.

CLINICAL RELEVANCE

Using an S-STARTS score-based assessment to monitor an athlete's progression through the return-to-sport continuum may help clinicians and strength and conditioning coaches in return-to-sport decision-making.

Glenoid Bone Loss Is a Risk Factor for Poor Clinical Results After Coracoid Transfer in Rugby Players With Shoulder Dislocations

Background:

Although surgical shoulder stabilization via coracoid transfer in collision athletes is effective and has a low reinjury rate, the factors affecting poor clinical results and the superiority of the 2 stabilization procedures (Bristow and Latarjet) remain unclear.

Purpose:

To explore the factor(s) affecting poor clinical results of coracoid transfer in a large cohort of rugby players and to compare postoperative function between the Bristow and Latarjet procedures.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

This study included 169 consecutive shoulders of 154 competitive male rugby players who underwent shoulder stabilization surgery (Bankart repair with coracoid transfer) between 2014 and 2018 and had a mean follow-up of 2.7 years (minimum follow-up, 2 years). The Bristow procedure was performed in the first 92 shoulders (84 players), and the Latarjet procedure was performed in the latter 77 shoulders (70 players). A poor clinical result was defined as a postoperative Rowe score of <70 and a postoperative Western Ontario Shoulder Instability Index (WOSI) score of >630. Multiple logistic regression analysis was conducted to identify the factors affecting postoperative functional failure. The postoperative scores and complication rates were also compared between the 2 procedures.

Results:

In total, 92.3% of the rugby players returned to their preinjury competition level at a mean of 5.9 months postoperatively. The Rowe and WOSI scores showed that shoulder function was improved postoperatively compared with preoperatively. The number of rugby players with a poor clinical result was 18 (10.7%). Multiple logistic regression analysis demonstrated that a poor clinical result was associated with a preoperative glenoid bone defect of >20% of the glenoid width (odds ratio, 9.8), whereas the clinical result was unaffected by the type of coracoid transfer. There were no differences between the 2 procedures in any of the postoperative scores or complication rates.

Conclusion:

The present study indicated that the most effective predictor of postoperative functional scores was the degree of the glenoid bone defect and not the type of coracoid transfer. This information may be useful for the strategic treatment of shoulder dislocations in collision athletes.

Outcomes of the Latarjet Procedure Versus Free Bone Block Procedures for Anterior Shoulder Instability: A Systematic Review and Meta-analysis

BACKGROUND

Free bone block (FBB) procedures for anterior shoulder instability have been proposed as an alternative to or bail-out for the Latarjet procedure. However, studies comparing the outcomes of these treatment modalities are limited.

PURPOSE

To systematically review and perform a meta-analysis comparing the clinical outcomes of patients undergoing anterior shoulder stabilization with a Latarjet or FBB procedure.

STUDY DESIGN

Systematic review and meta-analysis; Level of evidence, 4.

METHODS

PubMed, Embase, and the Cochrane Library databases were systematically searched from inception to 2019 for human-participants studies published in the English language. The search was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement including studies reporting clinical outcomes of patients undergoing Latarjet or FBB procedures for anterior shoulder instability with minimum 2-year follow-up. Case reports and technique articles were excluded. Data were synthesized, and a random effects meta-analysis was performed to determine the proportions of recurrent instability, other complications, progression of osteoarthritis, return to sports, and patient-reported outcome (PRO) improvement.

RESULTS

A total of 2007 studies were screened; of these, 70 studies met the inclusion criteria and were included in the meta-analysis. These studies reported outcomes on a total of 4540 shoulders, of which 3917 were treated with a Latarjet procedure and 623 were treated with an FBB stabilization procedure. Weighted mean follow-up was 75.8 months (range, 24-420 months) for the Latarjet group and 92.3 months (range, 24-444 months) for the FBB group. No significant differences were found between the Latarjet and the FBB groups in the overall random pooled summary estimate of the rate of recurrent instability (5% vs 3%, respectively; P = .09), other complications (4% vs 5%, respectively; P = .892), progression of osteoarthritis (12% vs 4%, respectively; P = .077), and return to sports (73% vs 88%; respectively, P = .066). American Shoulder and Elbow Surgeons scores improved after both Latarjet and FBB, with a significantly greater increase after FBB procedures (10.44 for Latarjet vs 32.86 for FBB; P = .006). Other recorded PRO scores improved in all studies, with no significant difference between groups.

CONCLUSION

Current evidence supports the safety and efficacy of both the Latarjet and FBB procedures for anterior shoulder stabilization in the presence of glenoid bone loss. We found no significant differences between the procedures in rates of recurrent instability, other complications, osteoarthritis progression, and return to sports. Significant improvement in PROs was demonstrated for both groups. Significant heterogeneity existed between studies on outcomes of the Latarjet and FBB procedures, warranting future high-quality, comparative studies.

Evaluating the effects of arthroscopic Bankart repair and open Latarjet shoulder stabilisation procedures on shoulder joint neuromechanics and function: a single-centre, parallel-arm trial protocol

Introduction

Shoulder instability injuries are common in sports involving collisions and overhead movements. Arthroscopic Bankart repair and the open Latarjet are two commonly used surgical stabilisation procedures. There is a lack of knowledge surrounding movement strategies, joint loading and muscle strength after each of these procedures. This study will compare: (1) shoulder joint neuromechanics during activities of daily living and an overhead sporting task; (2) shoulder range of motion; (3) shoulder strength; and (4) self-reported shoulder function and health status, between individuals who have undergone an arthroscopic Bankart repair versus open Latarjet.

Methods and analysis

This is a prospective cohort, single-centre, non-randomised parallel arm study of surgical interventions for athletic shoulder instability injuries. Thirty participants will be recruited. Of these, 20 will have experienced one or more traumatic shoulder instability injuries requiring surgical stabilisation—and will undergo an arthroscopic Bankart repair or open Latarjet procedure. The remaining 10 participants will have no history of shoulder instability injury and act as controls. Participants will undergo baseline testing and be followed up at 3, 6 and 12 months. A two-way (group×time) analysis of variance with repeated measures on one factor (ie, time) will compare each outcome measure between groups across time points.

Ethics and dissemination

This study was approved by the Barwon Health and Deakin University Human Research Ethics Committees. Outcomes will be disseminated through publications in peer-reviewed journals and presentations at relevant scientific conferences.

Bristow versus Latarjet in high-demand athletes with anterior shoulder instability: a prospective randomized comparison

Background

Traumatic anterior shoulder instability is a common disease, especially in young athletes. The Latarjet and Bristow techniques are nonanatomical surgeries that involve the transfer of the coracoid process to the anterior border of the glenoid and are indicated in cases at a high risk for recurrence and in the presence of associated bone lesions. Studies have evaluated the recurrence and complications associated with these techniques, but they have important differences, and should not be considered synonymous. The objective of this study was to prospectively compare the Bristow and Latarjet techniques in high-demand athletes. Hypothesis: Bristow and Latarjet techniques lead to similar results.

Patients and methods

Thirty-seven athletes (41 shoulders; three athletes underwent bilateral surgery) with anterior recurrent dislocation of the shoulder that was surgically treated using the Bristow or Latarjet technique were prospectively analyzed. The follow-up time was 5 years. The mean age was 26.4 years (range: 16-46 years). In 17 cases (41.5%), the dominant side was not affected.

Results

Elevation and external rotation (passive and active) decreased in the early postoperative period and achieved values in the final follow-up similar to those found in the preoperative period. The mean postoperative scores at 5 years were as follows: ASES, 79.1 (range: 66-95); ASORS, 77.8 (range: 60-100); WOSI, 52.6 (range: 18-77); and VAS, 1.88 (range: 0-6). All of the results presented statistical significance. There was a complication rate of 9.75% in the follow-up period. There were no new dislocations after the surgery. Most (75%) of the athletes returned to the sport after the surgery, and there was no correlation between poor results and any of the variables studied. There was a statistically significant difference in passive external rotation in favor of the Latarjet technique four weeks after surgery (P = .01). We also found a statistically significant difference in passive elevation in favor of the Latarjet technique eight weeks after the surgery (P = .04). When we compared the Bristow and Latarjet techniques regarding the ASES, ASORS, and WOSI scores, we found no statistically significant difference. In the comparison regarding whether the athletes returned to sports, we found no statistically significant difference.

Conclusion

The Bristow and Latarjet techniques lead to good results in athletes with no new dislocation episodes and are suitable for treating patients with anterior recurrent dislocation of the shoulder. The Latarjet technique showed better results in some of the variables studied.

Latarjet procedure enables 73% to return to play within 8 months depending on preoperative SIRSI and Rowe scores

PURPOSE

Systematic reviews report return to play (RTP) within 5.8 months (range, 3-8) following the Latarjet procedure, but the factors that influence RTP remain unknown. The present study aimed to report the rate and time of return to play (RTP) during the first 8 months following the Latarjet procedure, and to determine the influence of sport type or patient characteristics.

METHODS

The authors retrospectively collected the records of patients that underwent Latarjet procedures for anterior shoulder instability between 2015 and 2017. Patients were excluded if they had any concomitant rotator cuff tendon lesions, or previous ipsilateral shoulder surgery. The authors retrieved patient demographics, time from injury to surgery, type of sport practiced (overhead/non-overhead, contact/non-contact), as well as pre- and postoperative Western Ontario Shoulder Instability index (WOSI), Shoulder Instability-Return to Sport After Injury index (SIRSI), and Rowe score.

RESULTS

A total of 217 patients (217 shoulders) were eligible for inclusion, comprising 184 males and 33 females, aged 26.8 ± 7.3 years at index surgery. The main sport practiced prior to surgery involved overhead (n = 173, 80%) and/or contact (n = 152, 70%) activities. By 8 month follow-up, 158 patients (73%) resumed their main sport, at a mean of 5.1 ± 1.5 months. Multivariable analysis revealed that RTP was more likely in patients with higher preoperative Rowe score (OR, 1.02; p = 0.024) and SIRSI score (OR, 1.02; p = 0.008).

CONCLUSIONS

By 8 months following the Latarjet procedure, 73% of patients had resumed their main sport. The likelihood of RTP was significantly associated with preoperative Rowe and SIRSI scores, but not with sport type.

Treatment type may influence degree of post-dislocation shoulder osteoarthritis: a systematic review and meta-analysis

PURPOSE

Age at primary dislocation, recurrence, and glenoid bone loss are associated with development of osteoarthritis (OA). However, an overview of OA following traumatic anterior shoulder instability is lacking and it is unclear to what degree type of surgery is associated with development of OA in comparison to non-operative treatment. The aim of this study was to determine the degree of OA at long-term follow-up after non-operative and operative treatments for patients with anterior shoulder instability. Surgery is indicated when patients experience recurrence and this is associated with OA; therefore, it was hypothesized that shoulders show a higher proportion or degree of OA following operative treatment compared to non-operative treatment.

METHODS

A literature search was performed in the PubMed/Medline, EMBASE, and Cochrane databases. Articles reporting the degree of OA that was assessed with the Samilson-Prieto or Buscayret OA classification method after non-operative and operative treatment for anterior shoulder instability with a minimum of 5 years follow-up were included.

RESULTS

Thirty-six articles met the eligibility criteria of which 1 reported the degree of OA for non-operative treatment and 35 reported the degree of OA for 9 different operative procedures. A total of 1832 patients (1854 shoulders) were included. OA proportions of non-operative and operative treatments are similar at any point of follow-up. The Latarjet procedure showed a lower degree of OA compared to non-operative treatment and the other operative procedures, except for the Bristow procedure and Rockwood capsular shift. The meta-analyses showed comparable development of OA over time among the treatment options. An increase in OA proportion was observed when comparing the injured to the contralateral shoulder. However, a difference between the operative subgroups was observed in neither analysis.

CONCLUSION

Non-operative and operative treatments show similar OA proportions at any point of follow-up. The hypothesis that shoulders showed a higher proportion or degree of OA following operative treatment compared to non-operative treatment is not supported by the data. Operative treatment according to the Latarjet procedure results in a lower degree of OA compared to other treatments, including non-operative treatment.

Proximal-medial part in the coracoid graft demonstrates the most evident stress shielding following the Latarjet procedure: a simulation study using the 3-dimensional finite element method

BACKGROUND

Although the osteolysis of the coracoid graft is frequently observed after the Latarjet procedure particularly in its proximal part, its pathomechanism is not well understood.

METHODS

Three-dimensional finite element glenohumeral joint models were developed using CT-DICOM data of 10 normal shoulders. A 25% bony defect was created on the anterior glenoid rim, and the coracoid process was transferred flush with the glenoid cartilage using 2 half-threaded screws. In the hanging arm as well as in the 90° abducted positions, a compressive load (50 N) was applied to the greater tuberosity toward the center of the glenoid and a tensile force (20 N) was applied to the coracoid tip along the direction of the conjoint tendon. Next, elastic analysis was performed, and the distribution patterns of the equivalent stress as well as the maximum principal stress were compared among 4 parts (proximal/distal and medial/lateral) of the coracoid graft.

RESULTS

Both the equivalent stress and the maximum principal stress were reduced in the proximal half of the coracoid graft. A high stress concentration was observed in the lateral aspect of the coracoid graft particularly in the 90° abducted position. The proximal-medial part demonstrated the lowest equivalent stress as well as the maximum principal stress for both arm positions, which were significantly lower than those in the distal 2 parts.

CONCLUSION

In the Latarjet procedure, the proximal-medial part of the coracoid graft demonstrated the most evident stress shielding, which may play an important role in postoperative osteolysis.

Anterior Shoulder Instability in the Professional Athlete: Return to Competition, Time to Return, and Career Length

Background:

Anterior shoulder instability is a common condition in professional athletes, yet little is known about the success of surgery. Return to competition (RTC) is a metric indicative of a successful outcome for professional athletes who undergo anterior shoulder stabilization surgery.

Purpose:

To determine the rate of RTC, time to RTC, recurrence rate, and length of career after surgery in professional athletes who had undergone surgical treatment for anterior shoulder instability.

Study Design:

Case series; Level of evidence, 4.

Methods:

We evaluated professional athletes who underwent surgical treatment for anterior shoulder instability by a single surgeon between 2007 and 2018. Data from patients’ medical records, a patient data registry, basic search engines, sports websites, and individual team websites were used to determine length of professional play before injury, duration of career after surgery, and RTC level.

Results:

Overall, 23 professional athletes (25 shoulders from 12 contact and 13 noncontact athletes) were identified. The mean age at the time of surgery was 24.3 ± 4.9 years (range, 16-35 years). Primary procedures included arthroscopic Bankart repair (76%; 19/25), open Latarjet (20%; 5/25), and bony Bankart repair (4%; 1/25). Of the 23 athletes, 22 returned to their previous level of competition (96%; 95% CI, 78%-100%). The mean time between surgery and RTC was 4.5 months (range, 3-8 months). There was no difference in time to RTC between contact and noncontact athletes (4.1 vs 4.4 months). There was no difference in RTC rates and time to return for players who received a Bankart repair versus a Latarjet procedure (4.6 vs 4.2 months). A total of 12 participants were still actively engaged in their respective sport at an average of 4.3 years since surgery, while 11 athletes went on to retire at an average of 4.8 years. Duration of play after surgery was 3.8 years for contact athletes and 5.8 years for noncontact athletes (P > .05).

Conclusion:

In this series, professional athletes who underwent surgical shoulder stabilization for the treatment of anterior glenohumeral instability returned to their presurgical levels of competition at a high rate. No differences in RTC rate or time to RTC were observed for contact versus noncontact athletes or for those who received arthroscopic Bankart repair versus open Latarjet. However, contact athletes had shorter careers after surgery than did noncontact athletes.

Outcomes of the Latarjet procedure with minimum 5- and 10-year follow-up: A systematic review

BACKGROUND

The purpose of this study was to evaluate mid- and long-term outcomes following the Latarjet procedure for anterior shoulder instability.

METHODS

PubMed, MEDLINE, Embase, and Cochrane libraries were systematically searched, in line with PRISMA guidelines, for studies reporting on outcomes following the Latarjet procedure with minimum five-year follow-up. Outcomes of studies with follow-up between 5 and 10 years were compared to those with minimum follow-up of 10 years.

RESULTS

Fifteen studies reporting on 1052 Latarjet procedures were included. Recurrent instability occurred in 127 patients, with an overall random summary estimates in studies with a minimum five-year follow-up of 0-18% (I² = 90%) compared to 5-26% (I² = 59%) for studies with a minimum 10-year follow-up. Overall rates for return to sports, non-instability related complications, and progression of arthritis estimated at 65-100% (I² = 87%), 0-20% (I² = 85%), and 8-42% (I² = 89%) for the minimum five-year follow-up studies and 62-93% (I² = 86%), 0-9% (I² = 28%), and 9-71% (I² = 91%) for the minimum 10-year follow-up studies, respectively. All studies reported good-to-excellent mean PRO scores at final follow-up.

CONCLUSIONS

The Latarjet is a safe and effective procedure for patients with shoulder instability. The majority of patients return to sport, though at long-term follow-up, a trend towards an increased incidence of recurrent instability is appreciated, while a significant number may demonstrate arthritis progression.

Functional outcome and return to sports after the arthroscopic latarjet procedure in young and physically active patients

PURPOSE

The ideal treatment strategy for traumatic anterior shoulder instability with glenoid bone loss in young, physically active patients is still controversial. This study examines sporting activity, the ability to practice sports and the ability to return to sports after the arthroscopic Latarjet procedure.

METHODS

A total of 47 physically active patients with an average age of 24.5 ± 5.9 years were included in the study and evaluated at a minimum of two years after surgical treatment using shoulder and sport-specific scores. The shoulder sport activity score, Brophy marx activity score, Athletic shoulder outcome scoring system and the SPORTS score were used to assess the ability to practice sports, the sporting activity and the ability to return to sports. To assess functional outcome and shoulder stability, the evaluation was conducted using the Western Ontario shoulder instability index, the Constant score, the American shoulder and elbow surgeon score, and the Subjective shoulder value.

RESULTS

89.4% of the patients examined were able to perform the sport they had previously practiced after an average of 4.6 ± 2.0 months. Overhead athletes and martial arts athletes demonstrated a significantly lower return to sports rate than non-collision/non-overhead athletes (p = 0.01). With regard to sport-, instability-, or function-specific scores, no significant difference was found between patients after primary Latarjet procedure and patients after Latarjet procedure following a failed open or arthroscopic Bankart repair. All scores showed good to very good functional results on average. Two patients suffered a traumatic recurrent instability (4.1%) during the follow-up period and were therefore excluded from this study.

CONCLUSION

Arthroscopic Latarjet procedure presents a good surgical option, especially for young, physically active patients; it has very good clinical outcome, a high return to sports rate and a low probability of recurrent dislocation.

Return to Sport After Coracoid Bone Block Transfer for Shoulder Instability: A Systematic Review

BACKGROUND

Shoulder dislocations can be devastating for an athlete. Coracoid bone block transfer is often used for the treatment of recurrent shoulder instability.

QUESTIONS/PURPOSES

The primary purpose of this study was to determine the rate and mean time of return to sport in athletes after a coracoid bone block transfer at the pre-operative level of competition, a lower level, or a different level. We also sought to determine how return to sport rates after a coracoid bone block procedure compared with rates after several comparator interventions. Finally, we looked to determine the post-operative clinical outcomes and complications reported after a coracoid bone block procedure.

METHODS

We systematically searched three databases (PubMed, Embase, and MEDLINE) for studies reporting return to sport after a coracoid bone block procedure.

RESULTS

A total of 52 studies (with levels of evidence ranging from II to IV) evaluating 2953 shoulders in 2888 patients were included in this systematic review. The mean rate of return to sport at any level was 88.4% (2291 of 2592 patients). However, the rate of return to the pre-operative level was 70.3% (1387 of 1974 patients). The mean time to return to sport was 5.38 months (range 21 days to 36 months). The rate of return to sport was higher after the Latarjet procedure, as compared with Bankart repair (87.0% and 75.8%, respectively). All studies showed improvements in clinical outcome measures after coracoid bone block intervention. The cumulative complication rate was found to be 6.46% (158 of 2446 patients).

CONCLUSION

Coracoid bone block transfer allows for a high rate of return to sport, although the rate of return to sport at athletes' pre-operative level is lower. The rate of return to sport after Latarjet procedure is higher in comparison with Bankart repair. Additionally, coracoid bone block transfer is associated with improvements in a number of clinical outcome measures. Common post-operative complications include non-union between bone block and glenoid, hematoma, and infection.

Current practices in the management of anterior glenohumeral instability in rugby union players

BACKGROUND

Rugby has the highest incidence of traumatic injuries of any sport, and glenohumeral injuries result in the lengthy delay in return to play. The purpose of this study is to survey surgeons from the American Shoulder and Elbow Surgeons (ASES), and the British Elbow and Shoulder Society (BESS) to evaluate the current state of management of anterior glenohumeral instability, and compare the differences in practices.

METHODS

A survey of surgeons from ASES and BESS was conducted. Treatment options were proposed in a variety of clinical scenarios of glenohumeral instability. The time of immobilization post-operatively, return to play, and attitudes on current contact regulations. Results were compared using the chi-square test or t-test.

RESULTS

Ninety-seven surgeons responded to the survey. There was a significant difference in treatment between ASES and BESS surgeons in the setting of primary dislocation (p < 0.05), but not recurrent dislocation (p > 0.05). The period of immobilization following injury and surgery was different between both treating groups. There was a significant difference in return to play between ASES and BESS surgeons with arthroscopic stabilization and open Bankart repair (p < 0.05), but not following conservative treatment or the Latarjet procedure (p > 0.05).

CONCLUSIONS

There remains wide variance on the management of glenohumeral instability in rugby union players among surgeons. While immobilization times post-operatively were similar, the BESS surgeons were more confident in allowing earlier return to play. There is also a significant concern that contact levels should be regulated to protect player safety.

Editorial Commentary: Classic and Congruent-Arc Latarjet Techniques Are Equally Safe and Effective Procedures, so Choose Whichever Technique Works Best in Your Hands for Your Patients

The classic and congruent-arc Latarjet techniques are equally safe and effective in restoring glenohumeral stability, even when performed as a revision of a failed stabilization. The classic technique provides a broader contact area for healing and facilitates and improves screw fixation. The congruent-arc technique theoretically optimizes glenohumeral contact forces because of the matched radius of curvature, provides better restoration of glenoid depth, and restores larger glenoid defects. However, rotating the coracoid graft for the congruent-arc technique eliminates the possibility of imbricating the coracoacromial ligament stump to the capsule. Surgeons have little reason to change from one technique to the other; both techniques result in successful outcomes.
