Abstract
BACKGROUND Many patients who undergo shoulder arthroplasty (SA) have had at least 1 nonarthroplasty shoulder surgery before the surgery. There is conflicting evidence regarding the effects of previous shoulder surgery on the outcome of SA. A systematic review was conducted to compare functional outcomes and complications between SA patients with and without prior non-SA surgery on the ipsilateral shoulder. METHODS We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and searched MEDLINE/PubMed, Embase, Scopus, and Web of Science comprehensively from inception to January 2023. Based on 9,279 records reviewed, 26 comparative studies were included in the meta-analysis consisting of 5,431 shoulders with prior nonarthroplasty procedures (cases) and 55,144 shoulders without previous surgery (controls). Variables such as functional scores, complications, and range of motion were compared between cases and controls using Review Manager Software. In addition, subgroup analysis was conducted based on prior surgery type (rotator cuff repair [RCR], open reduction and internal fixation [ORIF], soft tissue repairs, and not specified) and type of SA (hemiarthroplasty, anatomical total shoulder arthroplasty, and reverse total shoulder arthroplasty [RTSA]). The results were presented as odds ratios (ORs) or standardized mean differences (SMDs). RESULTS Except for a higher rate of periprosthetic joint infection (PJI) in patients who had undergone previous arthroscopic surgery (OR, 2.58; 95% confidence interval [CI], 1.66-4.01; p < 0.01), a higher rate of complications was only observed in patients with previous ORIF. These complications included aseptic loosening (OR, 3.43; 95% CI, 2.14-5.50; p < 0.01), shoulder dislocation (OR, 2.25; 95% CI, 1.05-4.84; p = 0.04), overall complication (OR, 3.95; 95% CI, 2.38-6.55; p < 0.01), and revision (OR, 2.52; 95% CI, 1.28-4.97; p = 0.01). Patients with a history of previous surgery demonstrated inferior functional outcomes in comparison with the control group, including American Shoulder and Elbow Surgeons (SMD, -0.39; 95% CI, -0.51 to -0.27; p < 0.01; I2 = 36%), Constant-Murley score (SMD, -0.34; 95% CI, -0.44 to -0.24; p < 0.01; I2 = 0%), abduction (SMD, -0.26; 95% CI, -0.45 to -0.08; p = 0.01; I2 = 54%), and flexion (SMD, -0.33; 95% CI, -0.46 to -0.21; p < 0.01; I2 = 40%). Subgroup analysis by previous type of surgery was not possible regarding functional outcomes. CONCLUSION Patients who have had prior fracture surgery are at a higher risk of complications, reoperations, and revisions after SA than controls. The normal shoulder anatomy may be disrupted by prior surgery, which makes arthroplasty technically challenging, particularly when it comes to soft tissue balance. On the other hand, RCR before SA did not negatively affect clinical outcomes after RTSA and did not have a higher rate of overall complications (except PJI).

Abstract
OBJECTIVE To continuously absorb new teaching concepts and try new teaching methods in the process of clinical practice teaching for medical students to improve the teaching effect. METHODS In the process of clinical practice teaching of orthopedic, the teaching concept of "hand and foot" was adopted. RESULTS In the process of clinical practice teaching for medical students, the "hand as foot teaching philosophy" was used to explain the abstract anatomical structures, which greatly stimulated students' interest in classroom learning and achieved good teaching effects. CONCLUSION The "hand as foot teaching philosophy" is a new teaching concept, which is worth exploring and applying in clinical practice, so as to continuously optimize and improve the theoretical system and better serve for teaching.

Arthroscopy 2024; 40:672-673.

Abstract
When determining surgical options for shoulder stabilization, patient age, lifestyle, and sport activities help inform which procedure to select. Additionally, there is a need for solidifying the accuracy and effectiveness of measuring glenoid bone loss, which can be the critical factor in choosing a soft tissue or bony augmentation procedure. Makovicka et al. found that using two-thirds of the glenoid height to generate a perfect-circle, rather than a "best-fit" circle improved reliability of MRI-based bone loss measurement. Two-thirds height technique employs a more objective measure of glenoid height, producing a perfect circle used to subsequently estimate glenoid bone loss, which is consistently reproducible, and can be performed in most clinical settings. This was supported by the improved intra-class correlation coefficient from the two-thirds height perfect circle over the "best-fit" circle measurement observed in this study.

Abstract
BACKGROUND It has not been clarified yet how much force is acting on the shoulder joint to create Hill-Sachs/reverse Hill-Sachs lesions which are commonly observed in patients with anterior or posterior shoulder instability. The purpose of this study was to determine the magnitude of force to create these bony lesions using cadaveric shoulders. METHODS Fourteen fresh-frozen cadaveric shoulders were used. Compression tests were performed using the universal testing machine. The specimens were randomly divided into two groups. In group A, the posterior humeral head (the bare area and articular cartilage) was first compressed against the anterior glenoid rim to simulate a Hill-Sachs lesion, followed by the anterior humeral head being compressed against the posterior glenoid rim. In group B, the same procedure was repeated in the reverse order. X-ray microcomputed tomography (microCT) was also performed. RESULTS The maximum compression force to create a Hill-Sachs lesion was 771 ± 214 N (mean ± SD) on the articular cartilage of the posterior humeral head, which was significantly greater than the force of 447 ± 215 N to create it on the bare area (P = 0.0086). Regarding the reverse Hill-Sachs lesions, the maximum compression force was 840 ± 198 N when it was created on the articular cartilage of the anterior humeral head, which was significantly greater than the force of 471 ± 100 N when it was created at the footprint of the subscapularis tendon (P = 0.0238). MicroCT showed multiple breakage of the trabecular bone. CONCLUSION A force to create a Hill-Sachs lesion or a reverse Hill-Sachs lesion was significantly greater when it was created on the humeral articular cartilage than at the non-cartilage area. Also, the force to create a reverse Hill-Sachs lesion was significantly greater than the one to create a Hill-Sachs lesion.

Abstract
Open reconstruction of the coracoclavicular (CC) and acromioclavicular (AC) ligaments results in excellent reduction of severely displaced AC dislocations, most commonly Grades III and V. Anatomic CC reconstruction through clavicular bone tunnels can prevent vertical instability, whereas the addition of an acromial limb of the graft can increase horizontal stability. Autograft tendon is preferred in the young athletic group of collision sports participants, although allograft has had acceptable results. Accessory fixation may be placed to protect the graft during healing, or for severe instability, especially for athletes involved in contact sports.

Abstract
BACKGROUND Since arthroscopy was discovered to treat acromioclavicular joint injury, people have had great interest and attention to this beautiful and minimally invasive operation, and related research has been increasing worldwide. At present, there is no bibliometric and visualized analysis in this field. The purpose of this study is to explore the research hotspots and trends of arthroscopic treatment of acromioclavicular joint injury through bibliometric and visualized analysis and look forward to the future development direction of clinical practice. METHODS The publications on arthroscopic treatment of acromioclavicular joint injury diseases from its establishment to April 2023 were obtained from the Web of Science (WOS) Core Collection database. CiteSpace, VOSviewer, Scimago graphica and Origin were used for bibliometric and visualized analysis. RESULTS This study included a total of 330 publications. The number of publications tends to increase every year. The USA has the most significant number of publications and citations. Imhoff AB is the most relevant scholar with the largest number of publications in this field, and the scholar with the highest citation and average citations is Mazzocca AD. Tech Univ Munich, Rush University and Charite are the three institutions with the greatest contribution. Tech Univ Munich, Rush University and Charite are the three institutions with the greatest contribution. In addition, "Arthroscopy-the Journal of Arthroscopic and Related Surgery" and "American Journal of Sports Medicine" are the institutions with the most significant number of publications and average citations, respectively. The most common keywords are "acromioclavicular joint dislocation," "arthroscopic resection," "arthroscopic reconstruction" and "coracoclavicular ligament." CONCLUSION The number of publications shows a steady upward trend as a whole. However, there is still a lack of cooperation among countries, institutions and scholars around the world, so various countries, institutions and scholars need to strengthen academic exchanges and expand the field of cooperation, so as to promote further research and development in related fields. However, minimally invasive methods such as arthroscopy are still the hotspots and frontiers in the treatment of acromioclavicular joint injury in the future.

Abstract
BACKGROUND The Western Ontario Shoulder Instability (WOSI) questionnaire is a 21-item questionnaire to evaluate quality of life in patients with shoulder instability. Completing the questionnaire is time-consuming because each item is evaluated on a visual analog scale. Telephone or email versions of the score are appealing alternatives to administering it during the standard in-person patient visit; however, their validity and reliability remain unknown. QUESTIONS/PURPOSES (1) Does the numerical scale (NS) version of the WOSI correlate with the original WOSI and Quick-DASH? (2) Do telephone and email administration of the NS-WOSI have good reliability and consistency? (3) Compared with the original WOSI form, does the NS form lead to faster completion for patients and quicker data extraction for researchers? METHODS Between 2014 and 2019, 50 patients with a documented history of shoulder dislocation with persistent symptomatic shoulder instability, whether anterior, posterior, or multidirectional; patients scheduled for surgery; and patients with traumatic or nontraumatic injuries were prospectively recruited from the outpatient clinic of two university hospitals acting as Level 1 trauma centers and sports traumatology tertiary referral centers. The median (IQR) age was 28 years (24 to 36), and 80% (40 of 50) were men. Most (52% [26 of 50]) patients had two to five lifetime shoulder dislocations. Validity of the NS-WOSI was assessed using the Pearson correlation coefficient during an in-person visit; the original WOSI questionnaire (or its previously validated French-language version), NS-WOSI, and Quick-DASH questionnaires were administered in a random order. After a minimum 7-day interval, 78% (39 of 50) of patients completed the phone interview, and 74% (37 of 50) of patients completed the email version of the NS-WOSI score to evaluate NS-WOSI's reliability using the intraclass correlation coefficient (ICC), which was interpreted as poor (< 0.5), moderate (0.50-0.75), strong (0.75-0.90), and very strong (> 0.90). The standard error of measurement (SEM) was used to evaluate variability around the true score, with a low value indicating a high reliability. The 95% minimal detectable change (MDC 95% ) was calculated to evaluate the minimal change in score that was not related to measurement errors. Lastly, the Cronbach alpha was used to assess internal consistency (intercorrelation strength), where a value > 0.70 was considered good. The time needed for the patient to complete the various versions and for researchers to extract data was recorded. RESULTS The NS-WOSI score was very strongly correlated with the original WOSI score (r = 0.96 [95% confidence interval (CI) 0.93 to 0.98]; p < 0.001). Although telephone-acquired and email-acquired data for the NS-WOSI questionnaires were correlated with the NS-WOSI (telephone r = 0.91 [95% CI 0.83 to 0.95]; p < 0.001; email r = 0.84 [95% CI 0.71 to 0.91]; p < 0.001), the ICC was higher for telephone interviews (0.92 [95% CI 0.86 to 0.96] versus email 0.80 [95% CI 0.64 to 0.89]), indicating that although both had good reliability, the phone interview was more suitable. The phone interview was also preferable to email regarding SEM (3% [52 of 2100 points] versus 6% [132 of 2100 points]) and the MDC 95% (7% [144 of 2100 points] versus 17% [366 of 2100 points]). The 95% CI of the MDC acquired by email was superior to the reported minimum clinically important difference for the original WOSI (7% [152 of 2100 points]), meaning that an error of measurement could wrongly be interpreted as a clinically significant change in score. Internal consistency was deemed good, with a Cronbach alpha of 0.96 (95% CI 0.92 to 98) and 0.89 (95% CI 0.79 to 0.94) for NS-WOSI telephone and email, respectively. The time to complete the NS-WOSI was reduced compared with the original WOSI (221 ± 153 seconds versus 266 ± 146 seconds, mean difference -45 seconds [95% CI -72 to -12]; p = 0.009). Lastly, data extraction was faster (62 ± 15 seconds versus 209 ± 52 seconds, mean difference -147 seconds [95% CI -164 to -130]; p < 0.001) with the NS-WOSI than with the original WOSI. CONCLUSION The NS-WOSI in person, by telephone, or by email is a valid, reliable, and timesaving alternative to the original WOSI questionnaire. However, the reliability of data acquisition by telephone interviews was superior to that of email. CLINICAL RELEVANCE Given that there were no important differences in performance for the NS-WOSI, regardless of whether it was administered in person or by phone, we suggest that physicians use both interchangeably based on patient convenience. However, we do not recommend using the email version, especially for research purposes, since it was not as reliable when compared with in-person administration. The responsiveness of the modified NS-WOSI, as well as factors influencing response rates to phone interview, are questions that remain to be explored.

Abstract
This study aimed to radiologically evaluate the effect of hook plates used in the treatment of acromioclavicular joint (ACJ) dislocations on the development of subacromial osteolysis (SAO) according to acromion types. A total of 43 patients with mean age of 38.5 (19-77) years who were diagnosed with AC dislocation and applied neutral clavicular hook plate between 2013 and 2020 were retrospectively evaluated. Acromion types were determined by measuring acromion slope angle on lateral shoulder radiography and 3-dimensional (D)-CT of the patients. Presence of SAO was classified according to the severity of erosion in the subacromial region (grade I: minimal osteolysis, grade II: subacromial erosion <2 mm, grade III: subacromial erosion >2 mm, grade IV: cut-through of the acromion) on postoperative 3D - CT and correlation with acromion types was analyzed. Incidence of SAO was significantly higher among type 1 acromion compared to type 2 and type 3 acromion (P = .003). While osteolysis was observed in 21 patients, no osteolysis was observed in 22 patients. Osteolysis occurred in all patients with type 1 acromion, 7 patients with type 2 acromion, and 5 patients with type 3 acromion. Since the hook tip in the sagittal plane passes posterior to the center of the acromion and the concavity of the subacromial surface is inadequate in the type 1 acromion, we believe that the increased pressure applied by the hook tip on the subacromial cartilage increases the risk of SAO. We predict that the use of hook plates with an angle of 15-20 degrees, similar to the patient's AC angle, rather than neutral hook plate, will reduce the risk of osteolysis in patients with type 1 acromion.

Abstract
The rotator cuff (RC) is frequently torn at the enthesis composed of fibrocartilage. We aimed to histopathologically evaluate lining layers and assess the distribution of a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS)4, ADAMTS5, and microRNA (miR)-140s in the synovia of patients with RC tears. We recruited 51 patients who underwent arthroscopic surgical treatment for full-thickness rotator cuff tears, including 26 patients with < 3 cm tear size (group N) and 25 patients with ≥ 3 cm tear size (group W). Biopsied synovia were analyzed using histological and immunohistological techniques for the presence ADAMTS4 and ADAMTS5. The layers of the synovial lining were morphologically classified into 3 grades according to the synovitis score and staining levels of ADAMTSs. The glenohumeral synovia from 8 patients with recurrent shoulder dislocation (group C) were used as controls. Furthermore, in situ hybridization was performed to evaluate the presence of miR-140s in patients with massive tears and recurrent shoulder dislocation. The staining levels were evaluated and analyzed based on comparison between patient groups and correlation between ADAMTS5 and miR-140s. Histological analysis revealed significant differences between groups W and C. ADAMTS5 and ADAMTS4 were strongly expressed in the synovial lining of patients in group W, and this expression was significantly higher than that in groups C and N. In addition, expression of ADAMTS5 was inversely correlated with that of miR-140-3p. This study showed that synovia from group W had a significantly higher rate of severely thickened areas with strong expression of both aggrecanases. Furthermore, the area with weak expression of miR-140-3p showed strong ADAMTS5 expression.

Abstract
INTRODUCTION One of the complications of the surgical therapy for proximal humerus fractures is fracture-related infection (FRI). This multicenter study aimed to investigate the incidence of FRI and clarify the risk factors associated with FRI in patients receiving open reduction and internal fixation for proximal humerus fracture. MATERIAL AND METHODS Among 684 patients diagnosed as having proximal humerus fracture and who were treated by surgical therapy in 13 institutions (named TRON group) from 2015 through 2020, 496 patients (men, n = 134, women, n = 362; mean [SD] age, 68.5 [14.5] years; mean [SD] body mass index [BMI], 23.0 [4.4] kg/m2) were included as subjects. Excluded were 188 patients due to less than 12 month's follow-up, patients who underwent osteosynthesis using neither plate nor nail and those with open fracture. We extracted the following as risk factors of FRI: sex, BMI, smoking status, diabetes, glenohumeral fracture dislocation, fracture classification, approach, implant, waiting period, type of anesthesia, operative time and blood loss during surgery. We conducted logistic regression analysis to investigate the risk factors of FRI using these extracted items as explanatory variables and the presence or absence of FRI as the response variable. RESULT FRI occurred after surgery for proximal humerus fracture in 9 of the 496 patients (1.8%). The causative organism was methicillin-susceptible Staphylococcus aureus in 4 patients, Pseudomonas aeruginosa in one patient and Enterococcus faecalis in one patient. In the other 3 patients, causative organisms were not detected. The univariate analysis showed significant differences for present of glenohumeral fracture dislocation (p = 0.004). Logistic regression analysis showed glenohumeral fracture dislocation to be the significant explanatory factor for FRI (odds ratio 12.3, p = 0.0375). CONCLUSION This study revealed an infection rate following open reduction and internal fixation of proximal humerus fracture of 1.8% (9 patients) and that Staphylococcus was the most frequent causative organism. Glenohumeral fracture dislocation is a significant risk for postoperative FRI.

Hybrid coracoclavicular and acromioclavicular reconstruction in chronic acromioclavicular joint dislocations yields good functional and radiographic results. Knee Surg Sports Traumatol Arthrosc 2022; 30:2084-2091. [PMID: 34841469 DOI: 10.1007/s00167-021-06790-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Accepted: 10/25/2021] [Indexed: 11/25/2022]
Abstract
PURPOSE Optimal treatment of chronic unstable acromioclavicular (AC) joint dislocations (stage 3-5 according the Rockwood classification) is still debated. Anatomic coracoclavicular (CC) reconstruction is a reliable option in terms of two-dimensional radiographic reduction, clinical outcomes, and return to sports, but there remain concerns regarding anterior-posterior stability of the AC joint with CC ligament reconstruction alone. The aim of the present study was to describe the mid-term results of a new hybrid technique with CC and AC ligament reconstruction for chronic AC joint dislocations. METHODS Twenty-two patients surgically treated for chronic AC joint dislocations (grade 3 to 5) were retrospectively reviewed. All patients were assessed before surgery and at final follow-up with the Constant-Murley score (CMS) and the American Shoulder and Elbow Surgeons (ASES) score. The CC vertical distance (CCD) and the CCD ratio (affected side compared to unaffected side) were measured on Zanca radiographs preoperatively, at 6 months postop and at final follow-up. The same surgical technique consisting in a primary fixation with a suspensory system, coracoclavicular ligaments reconstruction with a double loop of autologous gracilis and acromioclavicular ligaments reconstruction with autologous coracoacromial ligament was performed in all cases. RESULTS Twenty-two shoulders in 22 patients (19 males and 3 females) were evaluated with a mean age of 34.4 ± 9 years at the time of surgery. The mean interval between the injury and surgery was 53.4 ± 36.7 days. The mean duration of postoperative follow-up was 49.9 ± 11.8 months. According to the Rockwood classification, there were 5 (22.6%) type-III and 17 (77.2%) type-V dislocations. Mean preoperative ASES and CMS were 54.4 ± 7.6 and 64.6 ± 7.2, respectively. They improved to 91.8 ± 2.3 (p = 0.0001) and 95.2 ± 3.1 (p = 0.0001), respectively at final FU. The mean preoperative CCD was 22.4 ± 3.2 mm while the mean CCD ratio was 2.1 ± 0.1. At final FU, the mean CCD was 11.9 ± 1.4 mm (p = 0.002) and the mean CCD ratio was 1.1 ± 0.1 (p = 0.009). No recurrence of instability was observed. One patient developed a local infection and four patients referred some shoulder discomfort. Heterotopic ossifications were observed in three patients. CONCLUSIONS The optimal treatment of chronic high-grade AC joint dislocations requires superior-inferior and anterior-posterior stability to ensure good clinical outcomes and return to overhead activities or sports. The present hybrid technique of AC and CC ligaments reconstruction showed good clinical and radiographic results and is a reliable an alternative to other reported techniques.

Abstract
We describe a shoulder reduction technique by direct distraction at the glenohumeral joint in supine position. The technique can be performed by one or two providers and has an easy learning curve, and the use of anesthesia is not mandatory. It is anatomically based and combines traction-counter-traction technique along with scapula manipulation.

Abstract
INTRODUCTION Although the coracoid process seems to play an important anatomical role, there are few reports concerning fracture nonunion of the coracoid process (CN) and its disorders. Therefore, there is no widely accepted standard for the treatment of CN. MATERIALS AND METHODS PubMed and Scopus were searched using "scapular fracture" and "coracoid fracture" as search terms. The inclusion criteria were English full-text articles concerning coracoid fracture, and articles that described patient characteristics and presented appropriate images. The exclusion criteria were descriptive cases, and cases without appropriate images. Citation tracking was conducted to find additional articles and notable full-text articles written in other languages. Fractures were classified using Ogawa's functional classification, with Eyres' anatomical classification used as a supplement when necessary. RESULTS Twenty-nine patients (26 men, 3 women) with 30 CN were identified. Nine CN had a predisposing factor such as seizure disorder and renal osteodystrophy. The fracture types were 12 Ogawa type I and 18 type II. Concurrent shoulder girdle injuries at the time of initial trauma/accident were varied. There were six cases of double disruption and two of triple disruption of the superior shoulder suspensory complex (SSSC), all of which had Ogawa type I fracture. Only six CN were isolated. The most frequent cause of CN was oversight by the previous physician (n = 11), followed by conservative treatment (n = 7). Although 12 patients with 13 CN had symptoms attributable to CN, most of these symptoms were insignificant. Although the acromioclavicular dislocation or CN persisted in eight patients, these residual abnormalities did not significantly affect the outcomes. CONCLUSIONS Physicians treating CN should recognize that CN itself is frequently asymptomatic, and a satisfactory outcome is achieved solely by treating the concurrent injuries, even if CN remains. When CN is suspected to produce symptoms, the physician must then determine the mechanism by which the symptoms are produced, and select a treatment strategy. LEVEL OF EVIDENCE V.

Abstract
Latarjet coracoid bone-block is a gold-standard procedure for anteroinferior instability of the shoulder. Nowadays, it can be performed as open surgery or entirely under arthroscopy. The pure arthroscopic technique has the advantage of allowing concomitant intra-articular surgery, but involves a long learning curve. Here we present a hybrid concept using dedicated instrumentation comprising a specific guide with or without arthroscopic step, and notably ensuring the safety and reproducibility of the procedure, whatever the modality. This technique offers an alternative to arthroscopic coracoid bone block, performing the more complex steps as open surgery without major change to Latarjet's original technique, so as to enable concomitant intra-articular surgery if needed while getting around some of the limitations of the purely arthroscopic procedure.

Editorial Commentary: A Functional Capsule, Not the Type of Bone Graft, Determines Outcome After Shoulder Stabilization in Cases of Anterior Glenoid Bone Deficiency. Arthroscopy 2021; 37:2409-2411.

Abstract
Many clinical results of surgical treatment of recurrent anterior shoulder instability confirm the importance of anterior bone grafting of the glenoid defect. Some studies even propose to perform a graft, even when there is no bony defect. Short- and middle-term studies report comparable results between bone grafting and Latarjet procedure. But one of the main questions that still remains is the quality and efficiency of the capsule. If Latarjet is the gold standard in anterior shoulder stabilization with very good results at very long follow-up, it is probably because the capsule is replaced by the conjoint tendon. Because Latarjet is a difficult surgery and has some complexes and/or challenging complications and because it is a nonanatomic procedure, there is a true place for anterior bone grafting. This anterior grafting under arthroscopy provides excellent results, but it is mandatory to be sure that the shoulder capsule is working. Clinical, functional, and imaging studies of this capsule need to be performed for a better understanding of the unstable shoulder function and treatment.
