Abstract
BACKGROUND The Latarjet procedure is increasingly being utilized for the treatment of glenoid bone loss and has a relatively high neurological complication rate. Understanding the position-dependent anatomy of the axillary nerve (AN) is crucial to preventing injuries. PURPOSE To quantify the effects of changes in the shoulder position and degree of glenoid bone loss during the Latarjet procedure on the position of the AN. STUDY DESIGN Controlled laboratory study. METHODS A total of 10 cadaveric shoulders were dissected, leaving the tendons of the rotator cuff and deltoid for muscle loading. The 3-dimensional position of the AN was quantified relative to the inferior glenoid under 3 conditions: (1) intact shoulder, (2) Latarjet procedure with 15% bone loss, and (3) Latarjet procedure with 30% bone loss. Measurements were obtained at 0°, 30°, and 60° of glenohumeral abduction (equivalent to 0°, 45°, and 90° of shoulder abduction) and at 0°, 45°, and 90° of humeral external rotation (ER). RESULTS Abduction of the shoulder to 60° resulted in a posterior (9.5 ± 1.1 mm; P < .001), superior (3.0 ± 1.2 mm; P = .013), and lateral (19.1 ± 2.3 mm; P < .001) shift of the AN, and ER to 90° resulted in anterior translation (10.0 ± 1.2 mm; P < .001). Overall, ER increased the minimum AN-glenoid distance at 30° of abduction (14.9 ± 1.3 mm [0° of ER] vs 17.3 ± 1.5 mm [90° of ER]; P = .045). The Latarjet procedure with both 15 and 30% glenoid bone loss resulted in a superior and medial shift of the AN relative to the intact state. A decreased minimum AN-glenoid distance was seen after the Latarjet procedure with 30% bone loss at 60° abduction and 90° ER (17.7 ± 1.6 mm [intact] vs 13.9 ± 1.6 mm [30% bone loss]; P = .007), but no significant differences were seen after the Latarjet procedure with 15% bone loss. CONCLUSION Abduction of the shoulder induced a superior, lateral, and posterior shift of the AN, and ER caused anterior translation. Interestingly, the Latarjet procedure, when performed on shoulders with extensive glenoid bone loss, significantly reduced the minimum AN-glenoid distance during shoulder abduction and ER. These novel findings imply that patients with substantial glenoid bone loss may be at a higher risk of AN injuries during critical portions of the procedure. Consequently, it is imperative that surgeons account for alterations in nerve anatomy during revision procedures. CLINICAL RELEVANCE This study attempts to improve understanding of the position-dependent effect of shoulder position and glenoid bone loss after the Latarjet procedure on AN anatomy. Improved knowledge of AN anatomy is crucial to preventing potentially devastating AN injuries during the Latarjet procedure.

Abstract
Multidirectional instability of the shoulder has a complex pathoanatomy. It is characterized by a redundant glenohumeral capsule and increased joint volume. Subtle clinical presentation, unclear trauma history and multifactorial etiology poseses a great challenge for orthopedic surgeons in terms of diagnosis. Generally accepted therapeutic approach is conservative and the majority of patients achieve good results with rehabilitation. In patients who are symptomatic despite appropriate rehabilitation, surgical intervention may be considered. Good results have been obtained with open inferior capsular surgery, which has historically been performed in these patients. In recent years, advanced arthroscopic techniques have taken place in this field, and similar results compared to open surgery have been obtained with the less-invasive arthroscopic capsular plication procedure.

Abstract
Background: Contact athletes who experience posterior shoulder instability have a high likelihood of recurrence necessitating surgery. Indications: Patients with posterior shoulder instability without glenoid or humeral head bone loss who have failed activity modification, bracing, and physical therapy may benefit from arthroscopic stabilization surgery. Technique Description: We describe a technique for arthroscopic labral repair with capsular plication through 4 portals in the lateral decubitus position. Results: Arthroscopic capsulolabral reconstruction is an effective and reliable treatment for posterior shoulder instability with good patient-reported outcomes, low recurrence rates, and high rate of return-to-play. Discussion/Conclusion: Arthroscopic capsulolabral reconstruction in the lateral decubitus position with appropriately placed portals allows for safe and effective repair of the labrum and capsular plication to address posterior shoulder instability.

Abstract
BACKGROUND Recurrent anterior glenohumeral instability caused by a humeral avulsion of the glenohumeral ligament (HAGL) lesion has been studied, but very limited long-term evidence is available. PURPOSE To retrospectively review patients with a HAGL lesion who underwent an open Latarjet procedure for recurrent anterior shoulder instability. STUDY DESIGN Case series; Level of evidence, 4. METHODS A total of 16 patients with complete clinical and radiological data were available for a review. Clinical outcomes were assessed by range of motion, apprehension testing, the visual analog scale for pain, the Walch-Duplay score, the Rowe score, the Constant-Murley score, the Subjective Shoulder Value, and return to sports. Radiographs were reviewed for osteoarthritis and complications. RESULTS The median age of patients at the time of surgery was 28 years (range, 18-42 years). All patients were male with no hyperlaxity. The median follow-up time was 10 years (range, 2.8-15 years). Postoperative range of motion showed recovered forward elevation (median, 175°), external rotation (median, 62°), and internal rotation (median, 9 points). Overall, 87% returned to sports, with 68% to the same level and 93% satisfied or very satisfied. Median clinical outcomes were the following: visual analog scale score, 1 (range, 0-2); Walch-Duplay score, 86 (range, 75-100); Rowe score, 95 (range, 90-100); Constant-Murley score, 77 (range, 74-79); and Subjective Shoulder Value, 88% (range, 80%-95%). There were no recurrent dislocations or subluxations. One patient described mild long-term pain, and 1 patient had persistent stiffness. Other complications included 12% with subjective apprehension, 1 patient with a wound infection, and another patient with delayed bone graft union. Additionally, 56% of cases had mild postoperative arthritis at the final follow-up. There were no reoperations. CONCLUSION The open Latarjet procedure provided good outcomes with acceptable complication rates in the long term for patients with HAGL lesions. It is an effective treatment option and a safe alternative to arthroscopic or open HAGL repair.

Abstract
PURPOSE Case reports of nerve injuries following arthroscopic capsulolabral repair emphasize the proximity of major nerves to the glenoid. This study describes preoperative localization using nerve-sensitive magnetic resonance imaging in a small cohort of patients with iatrogenic nerve injuries following arthroscopic capsulolabral repair and the outcomes of nerve repair in these patients. METHODS Cases of iatrogenic nerve injury following arthroscopic capsulolabral repair referred to 2 surgeons from January 2017 to December 2019 were identified. Clinical charts, electrodiagnostic testing, magnetic resonance imaging studies, and operative reports were reviewed. RESULTS Four cases of iatrogenic nerve injury were identified. The time to presentation to our institution ranged from 2 weeks to 8 years. The axillary nerves in 3 cases were tethered by a suture at the inferior glenoid, whereas 1 case had a suture tied around the radial and median nerves inferior to the glenohumeral joint capsule. One case underwent excision and nerve transfer, 1 underwent excision and nerve repair, and 2 underwent suture removal and neurolysis. Open and arthroscopic approaches, including a recently described approach to the axillary nerve in the "blind zone," were used. Three cases demonstrated good recovery of all affected motor and sensory functions after surgery. At the 10-month follow-up, 1 case had persistent weakness, but there was evidence of axonal regeneration on electrodiagnostic testing. CONCLUSIONS Arthroscopic capsulolabral repair places regional nerves, particularly the axillary nerve, at risk owing to their proximity to the joint capsule and inferior glenoid. Patients with neuropathic pain in the distribution of affected nerves with corresponding sensorimotor loss following arthroscopic capsulolabral surgery should undergo focused magnetic resonance imaging with nerve-sensitive sequences and electrodiagnostic testing to localize the injury. The use of multiple surgical windows to the axillary nerve in the "blind zone" enables full visualization for neurolysis, suture removal, and nerve repair or transfer.

Abstract
BACKGROUND The location of the axillary nerve in the shoulder makes it vulnerable to traumatic or iatrogenic injury. Cadaveric studies have reported the location of the axillary nerve but are limited because of tissue compression, dehydration, and decay. Three-Tesla (T) magnetic resonance imaging (MRI) allows high anatomic resolution of neural structures. The aim of our study was to better define the location of the axillary nerve from defined bony surgical landmarks in vivo, using MRI scan. METHODS Using MRI, we defined a number of anatomic points and measured the distance from these to the perineural fat surrounding the axillary nerve using simultaneous tracker lines on both images. Two observers were used. RESULTS A total of 187 consecutive 3-T MRI shoulder scans were included. Mean age was 57.9 years (range 18-86). The axillary nerve was located at a mean of 14.1 mm inferior from the bony glenoid at the anterior border, 11.9 mm from the midpoint, and 12.0 mm from the posterior border. There was a significant difference between distance at the anterior border and midpoint (P < .001), and between the anterior and posterior borders (P < .001). The axillary nerve was located at a mean of 12.6 mm medial to the humeral shaft at the anterior border, 9.9 mm at the midpoint, and 8.6 mm from the posterior border. There was a significant difference between distance at the anterior border and midpoint (P = .008) and between the anterior and posterior borders (P = .002). The mean distance of the axillary nerve from the anterolateral edge of the acromion was 53.3 mm (95% confidence interval [CI] 52.3, 54.2; range 33.9-76.3). The mean distance of the axillary nerve from the inferior edge of the capsule was 2.7 mm (95% CI 2.9, 3.1; range 0.3-9.9). There was a positive correlation between humeral head diameter and axillary nerve distance from the inferior glenoid (R2 = 0.061, P < .001). There was a positive correlation between humeral head diameter and distance from the anterolateral edge of the acromion (R2 = 0.140, P < .001). CONCLUSION Our study has defined the proximity of the axillary nerve from defined anatomic landmarks. The proximity of the axillary nerve to the inferior glenoid and medial humeral shaft changes as the axillary nerve passes from anterior to posterior. The distance of the axillary nerve from the anterolateral edge of the acromion remains relatively constant. Both sets of distances may be affected by humeral head size. The study has relevance to the shoulder surgeon when considering "safe zones" during arthroscopic or open surgery.

Abstract
Background: Arthroscopic treatment of posterior shoulder instability has become more
popular and effective in recent years, but few data are available concerning
the rate of return to sport. Purpose: To present our experiences with arthroscopic posterior labral reconstruction
in athletes and review our results, with a particular focus on the rate of
return to sport. Study Design: Case series; Level of evidence, 4. Methods: Included in the study were 40 arthroscopic stabilizations performed because
of posterior shoulder instability in 37 athletes at a single institution.
During follow-up, the athletes’ rate of return to sport was calculated.
Shoulder function was evaluated based on a pre- versus postoperative
comparison of the Rowe instability score and the American Shoulder and Elbow
Surgeons score. Additionally, the return-to-sport rate was compared among
different subgroups: traumatic versus atraumatic origin of injury,
competitive versus recreational athletes, high-risk versus low-risk sport,
and posterior-only versus anterior and posterior stabilization. Data were
statistically analyzed using paired-samples t test and
nonparametric Fisher exact test. Results: The average follow-up period was 54.4 months (range, 24-112 months). Three
shoulders (7.5%) continued to have posterior subluxations postoperatively.
There were 34 excellent, 3 good, and 3 fair results based on the Rowe score
(average postoperative score, 92.9), and patients achieved an average
postoperative American Shoulder and Elbow Surgeons score of 92.7. The pre-
to postoperative improvement was statistically significant in both scoring
systems (P < .001). Of the 37 patients, 36 (98.2%) were
able to return to sport activity: 27 of them (72.9%) to their original sport
and 19 (51.4%) at their preinjury level. A significantly higher rate of
return to the same sport occurred in athletes who had traumatic injury
compared with a subgroup of athletes without a traumatic event
(P < .02). Conclusion: More than half of the athletes were able to return to their preinjury level
of sport after arthroscopic posterior labral reconstruction. In addition,
low recurrence rates and good functional outcomes were seen in >90% of
the patients, and 98% returned to sport activity. The athletes had a
significantly higher rate of return to sport if their posterior shoulder
instability had a clear traumatic origin.

Abstract
INTRODUCTION Axillary nerve injury is a major complication of shoulder surgery during glenoid exposure. The aim of this study was to measure the mean distance between the inferior glenoid and the axillary nerve in healthy shoulders and then to compare this distance between osteoarthritic and rotator cuff deficient glenohumeral joints. METHODS The magnetic resonance images of 50 patients with normal glenohumeral joints were reviewed. The infra-glenoid tubercle was determined as a fixed point and the distance to the axillary nerve was measured. Two separate assessors measured on the same sagittal sections. With a study power of 80%, the sample needed in each comparison group was 28 patients. Measurements were then performed on scans in patients with osteoarthritis and cuff tear arthropathy. The mean distance was compared between groups. RESULTS The mean distance between the infra-glenoid tubercle and axillary nerve was 12mm (standard deviation, SD, 5.6mm) in normal shoulders, 10.6mm (SD 5.4mm) in shoulders with osteoarthritis and 9.7mm (SD 3.7mm) in those with cuff tear arthropathy. For this sample size of 50 patients with a confidence interval of 95%, the mean range is 12mm (95% CI 10.4-13.6). A comparison between normal shoulder and osteoarthritis showed a p-value of 0.3, and between normal and cuff tear arthropathy a p-value of 0.06. This was not statistically significant. CONCLUSIONS The axillary nerve lies on average 12mm from the infra-glenoid tubercle. The presence of inferior osteophytes in glenohumeral osteoarthritis and the proximal migration of humeral head in cuff tear arthropathy does not seem to alter the course of the nerve significantly in relation to the inferior glenoid tubercle.

Abstract
OBJECTIVE To evaluate mid-term effectiveness of manipulation under anesthesia combined with arthroscopic capsular release and subacromial debridement for primary frozen shoulder. METHODS Between January 2013 and December 2017, 33 patients of primary frozen shoulder were treated with manipulation under anesthesia combined with 360° arthroscopic capsular release and subacromial debridement. There were 10 males and 23 females, aged from 37 to 65 years, with a mean age of 50.9 years. The affected shoulder on left side in 17 cases and on right side in 16 cases. The disease duration was 6-13 months (mean, 8.4 months). Before and after operation, the visual analogue scale (VAS) score was used to evaluate the shoulder joint pain, Constant score was used to evaluate the shoulder joint function, and the flexion, abduction, and external rotation of shoulder joint were recorded. The internal rotation function was assessed based on the vertebral plane that the thumb could reach after internal rotation of the affected shoulder joint (the rank of internal rotation vertebra). X-ray film was taken to measure the distance of the subacromial space. RESULTS There was no fracture or labrum tear in all patients, and all the incisions healed by first intention. All the 33 patients were followed up 20-31 months, with an average of 24.1 months. During the follow-up, there was no complication such as wound infection and nerve injury. At last follow-up, the range of motion of shoulder flexion, abduction, and external rotation, the rank of internal rotation vertebra, the VAS score, Constant score, and subacromial space were significantly improved when compared with preoperative ones ( P<0.05). CONCLUSION Manipulation under anesthesia combined with arthroscopic capsular release and subacromial debridement can achieve a good mid-term effectiveness without complication for primary frozen shoulder.

[PMID: 32109573 DOI: 10.1016/j.arthro.2020.02.016] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2019] [Revised: 02/07/2020] [Accepted: 02/08/2020] [Indexed: 02/02/2023]
Abstract
PURPOSE To investigate the incidence of axillary nerve palsy after arthroscopic shoulder stabilization and to measure the distance between the nerve and capsule in shoulders with a capsular lesion. METHODS This retrospective study included 2,027 shoulders (1,909 patients; 1,433 male and 476 female patients; mean age, 32 years [age range, 13-81 years]) subjected to arthroscopic soft-tissue stabilization for recurrent shoulder instability from 2005 to 2017. The exclusion criteria were bone grafting or transfer and preoperative axillary nerve symptoms. We retrospectively reviewed patient records and investigated the incidence and clinical features of axillary nerve palsy. We measured the closest distance between the axillary nerve and capsule on preoperative magnetic resonance images. RESULTS Postoperative axillary nerve palsy occurred in 4 shoulders (0.2% of all arthroscopic stabilizations). Capsular repair was performed in 2 shoulders (1.2% of 160 capsular repairs); humeral avulsion of the glenohumeral ligament (HAGL) repair, 1 shoulder (2% of 47 HAGL repairs); and isolated Bankart repair, 1 shoulder (0.05% of 1,941 Bankart repairs). The closest distance between the nerve and capsule was 3.4 ± 3.2 mm in shoulders with capsular or HAGL lesions and less than 1 mm in the 3 shoulders with palsy. The common symptoms in axillary nerve palsy cases were shoulder discomfort, delayed recovery of range of motion, and deltoid weakness and atrophy. A definitive diagnosis was made with electromyography in all cases. Nerve injury by a suture was confirmed during revision surgery in 3 shoulders subjected to capsular or HAGL repair during the initial operation. The palsy was transient and fully recovered in 1 shoulder with isolated Bankart repair. CONCLUSIONS The incidence of axillary nerve palsy after arthroscopic soft-tissue shoulder stabilization was low but higher in shoulders subjected to capsular or HAGL repair. We should always consider the possibility of axillary nerve palsy in shoulders that require capsular or HAGL repair. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
Since its first description over 30 years ago arthroscopic stabilisation has evolved. With improvements in knowledge, surgical techniques and materials technology, arthroscopic bankart repair has become the most widely used method for treating patients with symptomatic anterior shoulder instability. These procedures are typically performed in a younger, high demand patient population after a primary dislocation or to treat recurrent instability. A thorough clinical evaluation is required in the clinic setting not only to fully understand the injury pattern but also consider patient expectations prior to embarking on surgery. Diagnostic imaging will aid the clinician in determining the soft tissue pathology as well as assessing bone loss, which facilitates surgical decision-making. Selected patients may benefit from adjunctive procedures such as a remplissage for an "engaging" Hill-sachs lesion. This review will focus on the indications, pre-operative considerations, surgical techniques and outcomes of arthroscopic stabilisation.

Abstract
Frozen shoulder (FS) is a common shoulder disorder characterized by a gradual increase of pain of spontaneous onset and limitation in range of motion of the glenohumeral joint. The pathophysiology of FS is relatively well understood as a pathological process of synovial inflammation followed by capsular fibrosis, but the cause of FS is still unknown. Treatment modalities for FS include medication, local steroid injection, physiotherapy, hydrodistension, manipulation under anesthesia, arthroscopic capsular release, and open capsular release. Conservative management leads to improvement in most cases. Failure to obtain symptomatic improvement and continued functional disability after 3 to 6 months of conservative treatment are general indications for surgical management. However, there is no consensus as to the most efficacious treatments for this condition. In this review article, we provide an overview of current treatment methods for FS.

Abstract
BACKGROUND The aim of this study was to evaluate the risk of nerve injury with neuromonitoring during reverse total shoulder arthroplasty. MATERIALS This study included 15 shoulders of 15 patients (11 females and 4 males) who underwent reverse total shoulder arthroplasty. The mean age was 74.8 ± 4.4 years. Nine shoulders had cuff tear arthropathy, 4 had massive rotator cuff tears, 2 had osteoarthritis, and 1 had rheumatoid arthritis. The somatosensory evoked potentials of the median nerve, transcranial motor evoked potentials, and free-electromyograms from 6 upper-extremity muscles were measured intraoperatively. We defined a nerve alert as 50% amplitude attenuation or 10% latency prolongation of the somatosensory evoked potentials and transcranial motor evoked potentials and sustained neurotonic discharge on free-electromyogram. RESULTS Thirty-one alerts were recorded in 11 patients. The axillary nerve was associated with 17 alerts. Eleven alerts occurred during the glenoid procedure and 5 alerts occurred during the humeral procedure. One patient who did not recover from the alert of the axillary nerve had clinically incomplete paralysis of the deltoid muscle. CONCLUSION The present findings suggest that the axillary nerve was the nerve most frequently exposed to the risk of injury, especially during glenoid and humeral implantation.

Abstract
Background The axillary nerve is at risk during repair of a humeral avulsion of the glenohumeral ligament (HAGL). Purpose To measure the distance between the axillary nerve and the free edge of a HAGL lesion on preoperative magnetic resonance imaging (MRI) and compare these findings to the actual intraoperative distance measured during open HAGL repair. Study Design Case series; Level of evidence, 4. Methods A total of 25 patients with anterior instability were diagnosed as having a HAGL lesion on MRI and proceeded to open repair. The proximity of the axillary nerve to the free edge of the HAGL lesion was measured intraoperatively at the 6-o'clock position relative to the glenoid face. Preoperative MRI was then used to measure the distance between the axillary nerve and the free edge of the HAGL lesion at the same position. Distances were compared using paired t tests and Bland-Altman analyses. Results The axillary nerve lay, on average, 5.60 ± 2.51 mm from the free edge of the HAGL lesion at the 6-o'clock position on preoperative MRI, while the mean actual intraoperative distance during open HAGL repair was 4.84 ± 2.56 mm, although this difference was not significant (P = .154). In 52% (13/25) of patients, the actual intraoperative distance of the axillary nerve to the free edge of the HAGL lesion was overestimated by preoperative MRI. In 36% (9/25), this overestimation of distance was greater than 2 mm. Conclusion The observed overestimations, although not significant in this study, suggest a smaller safety margin than might be expected and hence a substantially higher risk for potential damage. We recommend that shoulder surgeons exercise caution in placing capsular sutures in the lateral edge when contemplating arthroscopic repair of HAGL lesions, as the proximity of the nerve to the free edge of the HAGL tear is small enough to be injured by arthroscopic suture-passing instruments.

Abstract
INTRODUCTION Recurrent posterior glenohumeral instability poses a challenge for treatment. Bone block procedures have been advocated in cases where a bony defect is present. However, these techniques are not free of complications due to the proximity of neurovascular structures. The aim of this study is to measure the distance to the axillary and suprascapular nerves at the different steps of the procedure. MATERIALS AND METHODS Ten frozen human cadavers were used. The bone graft was prepared and placed on the posterior aspect of the glenoid, where it was fixed with two K-wires in different positions: parallel to the articular surface and with 20° of medial angulation. The distance from the entry and exit points of the K-wires to the axillary and suprascapular nerves was measured. RESULTS At the exit point, mean distance from the superior K-wire to the axillary nerve was 4.4 mm in the neutral position and 14.4 mm when medially angulated (p = 0.01) and 2.6 mm and 11.5 mm, respectively, for the inferior K-wire (p < 0.01). No differences were found at the entry point (p = 0.7 and p = 0.3). For the suprascapular nerve, mean distance to the entry point of the superior K-wire was significantly greater when it was inserted with 20° of medial angulation than when placed in neutral position (p = 0.04). No differences were found for the inferior K-wire (p = 0.35). CONCLUSION Posterior bone block surgery should be performed taking into consideration the possibility of axillary nerve injury anteriorly at the exit point of the K-wires. Wire and screw insertion parallel to the glenoid articular surface may reduce the risk, while increased wire or screw medial angulation with respect to the glenoid surface may heighten risk. LEVEL OF EVIDENCE Not applicable (cadaveric study).

Abstract
PURPOSE To evaluate the risk of injuring the axillary nerve during an inferior glenohumeral ligament (IGHL) plication and finding out whether shoulder position (either beach chair position or lateral decubitus position) has any effect in this risk. METHODS The axillary nerve (AN) was identified through a 3-cm posterior incision in 12 cadaveric shoulders. Under arthroscopic visualization, a curved indirect suture-passing device was placed through the posterior and anterior bands of the IGHL. The distances between the device and the AN were measured with the shoulder specimen placed at simulated lateral decubitus position and beach chair position. RESULTS There were no cases of nerve injury nor the suture-passing device came closer than 10 mm to the nerve. There was an increase in the injury risk to the AN when inserting the device at the posterior band of the IGHL in the beach chair position [median 13 mm (range 10-21 mm)] compared to the risk in the lateral decubitus position [22.5 mm (20-26 mm), significant differences, p < 0.001]. When the device was inserted at the anterior band of the IGHL, there were no significant differences (n.s.) [lateral decubitus position: 18 mm (14-24 mm) vs. 16 mm (13-18 mm)]. When comparing differences between bands, there were no differences in the beach chair position, but the risk was lower for the posterior band in the lateral decubitus position (p < 0.001). CONCLUSIONS During plication of the posterior band of the IGHL, the risk is higher if the procedure is performed in the beach chair position. The posterior plication is safer than the anterior plication in lateral decubitus position. CLINICAL RELEVANCE This study helps the surgeon to better understand the proximity of the nerve to the IGHL and to highlight that the risk of nerve injury during capsular plication might be reduced in the lateral decubitus position.

Abstract
OBJECTIVE To evaluate the results of arthroscopic releases performed in patients with adhesive capsulitis refractory to conservative treatment. METHODS This was a retrospective study, conducted between 1996 and 2012, which included 56 shoulders (52 patients) that underwent surgery; 38 were female, and 28 had the dominant side affected. The mean age was 51 (29-73) years. The mean follow-up was 65 (12-168) months and the mean preoperative time was 8.9 (2-24) months. According to Zukermann's classification, 23 cases were considered primary and 33 secondary. With the patient in the lateral decubitus position, circumferential release of the joint capsule was performed: joint debridement; rotator interval opening; coracohumeral ligament release; anterior, posterior, inferior, and finally antero-inferior capsulotomy. A subscapularis tenotomy was performed when necessary. All patients underwent intense physical therapy in the immediate postoperative period. In 33 shoulders, an interscalene catheter was implanted for anesthetic infusion. Functional results were evaluated by the UCLA criteria. RESULTS Improved range of motion was observed: mean increase of 45° of elevation, 41° of external rotation and eight vertebral levels of medial rotation. According to the UCLA score excellent results were obtained in 25 (45%) patients; good, in 24 (45%); fair, in two (3%); and poor, in two (7%). Patients who had undergone inferior capsulotomy achieved better results. Only 8.8% of patients who used the anesthetic infusion catheter underwent postoperative manipulation. Seven patients had complications. CONCLUSION There was improvement in pain and range of motion. Inferior capsulotomy leads to better results. The use of the interscalene infusion catheter reduces the number of re-approaches.

Abstract
BACKGROUND There are little data on midterm outcomes after the arthroscopic management of glenohumeral osteoarthritis (GHOA) in young active patients. PURPOSE To report outcomes and survivorship for the comprehensive arthroscopic management (CAM) procedure for the treatment of GHOA at a minimum of 5 years postoperatively. STUDY DESIGN Case series; Level of evidence, 4. METHODS The CAM procedure was performed on a consecutive series of 46 patients (49 shoulders) with advanced GHOA who met criteria for shoulder arthroplasty but instead opted for a joint-preserving, arthroscopic surgical option. The procedure included glenohumeral chondroplasty, capsular release, synovectomy, humeral osteoplasty, axillary nerve neurolysis, subacromial decompression, loose body removal, microfracture, and biceps tenodesis. Outcome measures included the American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation (SANE), Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), Short Form-12 (SF-12) Physical Component Summary (PCS), visual analog scale for pain, and satisfaction scores. Kaplan-Meier survivorship analysis was performed with failure defined as progression to total shoulder arthroplasty (TSA). RESULTS Forty-six consecutive patients (49 shoulders) who underwent a CAM procedure at a minimum of 5 years from surgery were included. Two patients were excluded for refusing to participate before study initiation. The mean age at surgery was 52 years (range, 27-68 years) in 15 women and 29 men. All patients were recreational athletes with 7 former collegiate or professional athletes. Twelve shoulders (26%) progressed to TSA at a mean of 2.6 years (range, 0.5-8.2 years). For survivorship analysis, the status of the shoulder (preservation of the native joint or progression to TSA) at a minimum of 5 years was known for 45 of 47 (96%) shoulders. Survivorship was 95.6% at 1 year, 86.7% at 3 years, and 76.9% at 5 years. For surviving shoulders, minimum 5-year subjective outcome data were available for 28 of 32 (87.5%) shoulders at a mean of 5.7 years (range, 5-8 years). The mean (±SD) ASES score was 84.5 ± 17, the mean SANE score was 82 ± 18, the mean QuickDASH score was 15 ± 13, the mean SF-12 PCS score was 51.0 ± 9.1, and median patient satisfaction was 9 of a possible 10 points. CONCLUSION This study demonstrates significant improvements in midterm clinical outcomes and high patient satisfaction after the arthroscopic CAM procedure for GHOA, with a 76.9% survivorship rate at a minimum of 5 years postoperatively. For patients looking for an alternative to TSA, the CAM procedure can provide reasonable outcomes and should be considered an effective procedure in appropriately selected, young active patients. Further studies are warranted to evaluate long-term outcomes and durability after this procedure.

Abstract
UNLABELLED Shoulder stiffness can be caused by various etiologies such as immobilization, trauma, or surgical interventions. The Upper Extremity Committee of ISAKOS defined the term "frozen shoulder" as idiopathic stiff shoulder, that is, without a known cause. Secondary stiff shoulder is a term that should be used to describe shoulder stiffness with a known cause. The pathophysiology of frozen shoulder is capsular fibrosis and inflammation with chondrogenesis, but the cause is still unknown. Conservative treatment is the primary choice. Pain control by oral medication, intra-articular injections with or without joint distension, and physical therapy are commonly used. In cases with refractory stiffness, manipulation under anesthesia or arthroscopic capsular release may be indicated. Because of various potential risks of complications with manipulations, arthroscopic capsular release is preferred. After the capsular release, stepwise rehabilitation is mandatory to achieve satisfactory outcome. LEVEL OF EVIDENCE Level V, evidence-based review.

Abstract
BACKGROUND Postoperative pain management is the part of shoulder surgery to improve patient satisfaction, start rehabilitation process rapidly and decrease for hospital stay. Various treatment modalities have been used for pain management, but they have some limitations, side effects and risks. Throughout intraoperative and postoperative period, nerve blocks have been used more popularly than others because of efficacy. For the regional nerve block, local anesthetic should be infiltrated close to the nerve for maximum effect. Consequently, aim of this study was to evaluate analgesic efficacy when catheters are placed with assistance of arthroscope to block suprascapular and axillary nerves in patients undergoing arthroscopic repair of rotator cuff under general anesthesia. MATERIALS AND METHODS 24 patients (5 males, 19 females; mean age: 54.3 years) who underwent arthroscopic repair of rotator cuff between June 2014 and September 2014 and were catheterized to block suprascapular and axillary nerves during shoulder arthroscopy were included in the study. Clinical outcomes were assessed using visual analog scale (VAS) scores preoperatively and at 0 h, 6 h, 12 h, 18 h, 24 h, and postoperative day 2. RESULTS Preoperative and postoperative 0 h, 6 h, 12 h, 18 h, 24 h, and day 2 mean VAS scores were 6.38 ± 0.77, 0.44 ± 0.42, 0.58 ± 0.42, 0.63 ± 0.40, 0.60 ± 0.44, 0.52 ± 0.42, and 1.55 ± 0.46, respectively. No statistical difference was found among 0 h, 6 h, 12 h, 18 h, and 24 h time points; however, comparison of postoperative day 2 and postoperative 0 h, 6 h, 12 h, 18h and 24 h VAS scores showed statistically significant difference (P < 0.05). All patients were discharged at the end of 24 h with no complication. The mean time (in minutes) required for blocking suprascapular nerve and axillar nerve were 14.38 ± 3.21 and 3.75 ± 0.85, respectively. CONCLUSION These results demonstrated that blocking two nerves with arthroscopic approach was an excellent pain management method in postoperative period. Accordingly, patients could recover rapidly and patients' satisfaction could be improved.

Abstract
Idiopathic adhesive capsulitis, or primary frozen shoulder syndrome, is a fairly common orthopaedic problem characterized by shoulder pain and loss of motion. In most cases, conservative treatment (6-month physical therapy program and intra-articular steroid injections) improves symptoms and restores shoulder motion. In refractory cases, arthroscopic capsular release is indicated. This surgical procedure carries several advantages over other treatment modalities. First, it provides precise and controlled release of the capsule and ligaments, reducing the risk of traumatic complications observed after forceful shoulder manipulation. Second, release of the capsule and the involved structures with a radiofrequency device delays healing, which prevents adhesion formation. Third, the technique is straightforward, and an oral postoperative steroid program decreases pain and allows for a pleasant early rehabilitation program. Fourth, the procedure is performed with the patient fully awake under an interscalene block, which boosts the patient's confidence and adherence to the physical therapy protocol. In patients with refractory primary frozen shoulder syndrome, arthroscopic capsular release emerges as a suitable option that leads to a faster and long-lasting recovery.

Postoperative evaluation of drill holes for arthroscopic Bankart repair with suture anchors by the use of computed tomography. J Orthop Sci 2015; 20:481-7. [PMID: 25743369 DOI: 10.1007/s00776-015-0703-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2014] [Accepted: 01/14/2015] [Indexed: 10/23/2022]
Abstract
BACKGROUND Here we investigated the angle and placement of bone holes for suture anchors using postoperative computed-tomography scapula scans. METHODS The study group comprised 20 shoulders from 20 consecutive patients (13 males and seven females; mean age 23.4 years) who underwent arthroscopic Bankart repair. All anchors were inserted through the anterior portal after establishing a bone hole at the edge of the glenoid articular surface using a drill. Computed tomography images of the scapula were taken 1 month postoperatively and used to create three-dimensional scapula models with Mimics and Magics software. Bone holes in the anterior-inferior (3:00-6:00) position were assigned either to the non-perforated group if they were positioned entirely inside the glenoid bone or to the perforated group if the far cortex of the glenoid was penetrated by the drill. The angle between the glenoid articular surface and the bone hole was measured in the oblique coronal and transverse plane views. The length of the bone hole was also assessed. RESULTS Of the 85 bone holes investigated, 42 were in the 3:00-6:00 position. Perforation was detected in 16 of these 42 holes (38.2%). The angle in the oblique coronal plane view and the length of the bone hole were significantly larger in the non-perforated group than in the perforated group; however, the angle in the transverse plane view did not significantly differ between the two groups. CONCLUSIONS Before inserting an implant in the anterior-inferior area, the angle between the drill guide and the glenoid surface in the oblique coronal plane view should be carefully checked to ensure that the length of the hole inside the glenoid bone is adequate.

Abstract
Arthroscopic labral repair is a widely performed and safe technique for anterior or posterior shoulder instability; however, complications have been reported in the literature. Postoperative injection of local anesthetic via an intra-articular pain pump should be avoided to prevent chondrolysis of the glenohumeral joint. Postoperative stiffness of the shoulder can be treated with physiotherapy, and a surgical treatment is indicated in shoulders that failed a conservative treatment. Although nerve injury is relatively rare, the axillary nerve should be given careful attention. Recurrent shoulder instability is the most common complication after labral repair, but most reported rates of recurrent instability after arthroscopic Bankart repair are less than 10 %. Augmentations, such as rotator interval closure and Hill-Sachs remplissage, have a potential to reduce the rate of recurrence. A better understanding of these possible complications, including their pathology and treatment, is essential for optimization of outcomes after arthroscopic labral repair.

Abstract
PURPOSE The deltopectoral approach is a common surgical procedure for shoulder arthroplasty. Many surgeons are familiar with this procedure, but certain steps are still controversial. This is the case for the management of subscapularis, where surgeons must choose between tenotomy and the lesser tuberosity osteotomy. METHODS This article is conceived as a toolkit for the inexperienced surgeons, describing our tips and tricks to facilitate final exposure of the glenoid. For experienced surgeons, we analysed the tricky portions of the deltopectoral approach, comparing them with what is classically reported in the literature. RESULTS We describe an original technic for subscapularis reattachment after lesser tuberosity osteotomy in order to improve its stability. The medial part of the fragment is secondarily sculpted to obtain a step shape, which will be applied against the base of the prosthetic cup in a sort of "corner buttress". CONCLUSIONS Our work, based on our personal experience, confirms that there is no preferred single deltopectoral approach but, rather, multiple options. When embarking on this "shoulder highway", we encourage surgeons to respect the successive anatomic planes, which we believe is the only way to ensure easy and atraumatic dissection. KEY POINTS - The safe plane for going around the humeral head and positioning retractors is the plane of the subacromial deltoid bursa. - Always stay close to the bone during capsule release, whether on the humeral or glenoid side. - Never go medially to the conjoint tendon or its deep face.

Abstract
OBJECTIVE To determine the distance between the axillary nerve and the antero-lateral (AL) edge of the acromion, its anatomical variability and relationship to humeral length and body height. METHODS Twenty-two shoulders were dissected. The anterosuperior (AS) approach was used; the deltoid was detached from the acromion and the distance between the AL portion and the axillary nerve was measured and submitted to statistical analysis. RESULTS The distance varied from 4.3 to 6.4 cm (average 5.32 ± 0.60 cm). The axillary nerve distance increased as the humeral size (p<0.05) and the height of each cadaver increased. However, the correlation with the specimens height was not significant (p=0.24). CONCLUSIONS The distance between the acromion and the axillary nerve on the AS approach was 5.32 ± 0.60 cm in both shoulders, and increasing the humeral length there is also an increase in the axillary nerve distance.

Abstract
BACKGROUND Subclinical neurological lesions after reverse shoulder arthroplasty are frequent, mainly those involving the axillary nerve. One of the major reported risk factors is postoperative lengthening of the arm. The purpose of this study was to evaluate the anatomical relationship between the axillary nerve and prosthetic components after reverse shoulder arthroplasty. The study hypothesis was that inferior overhang of the glenosphere relative to glenoid could put this nerve at risk. MATERIAL AND METHODS Eleven fresh frozen shoulder specimens were dissected after having undergone reverse shoulder arthroplasty using a classic deltopectoral approach. RESULTS The mean distance from the inferior border of the glenoid to the inferior edge of the glenosphere was 6.0±4.3mm (range, 1.0 to 16.2mm). The axillary nerve was never closer than 15mm to the glenosphere. The main anterior branch of the axillary nerve was in close contact with the posterior metaphysis or humeral prosthetic implant. The mean distance between the nerve and the humeral implants was 5.2±2.1mm (range, 2.0 to 8.1mm). CONCLUSIONS The proximity of the axillary nerve to the posterior metaphysis or humeral implants may be a risk factor for axillary nerve injury after reverse shoulder arthroplasty. CLINICAL RELEVANCE This study quantifies the proximity of the axillary nerve to the implant after reverse shoulder arthroplasty. LEVEL OF EVIDENCE Basic science study, cadaver study.

Abstract
PURPOSE The purpose of this study was to assess the effectiveness of arthroscopic capsular release carried out for refractory cases of both primary and secondary adhesive shoulder capsulitis that were not responsive to at least 6 months of prior conservative therapy. METHODS Arthroscopic 360-degree capsular release was performed on 167 patients (173 shoulders) with adhesive shoulder capsulitis. Ninety-one shoulders (52.6%) had primary and 82 shoulders (47.4%) secondary adhesive capsulitis. The median follow-up period was 36 months (range 14-67 months). RESULTS All patients were evaluated according to the constant score. Both groups (primary and secondary adhesive capsulitis) experienced a significant improvement for all ranges of motion immediately postoperative, as well as at the time of follow-up. The median preoperative constant score was 41 (range 18-61) points and increased significantly to a median of 83 (range 27-100) at the time of follow-up. In the group of primary adhesive capsulitis, median preoperative score was 42 points (range 19-58) and increased to 85 points (range 36-100) at follow-up. In the group of secondary adhesive capsulitis, the preoperative mean increased from 41 points (range 18-61) to 74 points (range 27-100) at the time of the follow-up. The constant score component for pain and the visual analogue scale (VAS) score were also significantly increased. CONCLUSION Arthroscopic capsular release in patients with primary and secondary adhesive shoulder capsulitis represents a valuable therapeutic choice with minimal complications, to effectively reduce pain and improve movement in all planes of motion.

An association between the inferior humeral head osteophyte and teres minor fatty infiltration: evidence for axillary nerve entrapment in glenohumeral osteoarthritis. J Shoulder Elbow Surg 2013; 22:215-21.

Abstract
BACKGROUND Glenohumeral osteoarthritis often results in inferior humeral osteophytes. Anatomic studies suggest that the axillary neurovascular bundle is in close proximity to the glenohumeral capsule. We therefore hypothesize that an inferior humeral osteophyte of sufficient magnitude could encroach on the axillary nerve and result in measurable fatty infiltration of the teres minor muscle. MATERIALS AND METHODS Preoperative magnetic resonance imaging studies of 91 consecutive arthritic shoulders were retrospectively reviewed. Two cohorts were established based on the presence of a humeral osteophyte. The distances from the axillary neurovascular bundle to various osseous structures were measured using calibrated software. Objective quantitative measurements of the degree of fatty infiltration of the teres minor muscles were obtained with image analysis software. Results were compared between cohorts. RESULTS The distance between the inferior humerus and axillary neurovascular bundle was inversely correlated to the size of the inferior humeral osteophyte (ρ = -0.631, P < .001). Fatty infiltration of the teres minor was greater when an inferior osteophyte was present (11.9%) than when an osteophyte was not present (4.4%) (P = .004). A statistically significant correlation between the size of the humeral head spur and quantity of fat in the teres minor muscle belly (ρ = 0.297, P = .005) was identified. CONCLUSION These data are consistent with our hypothesis that the axillary nerve may be entrapped by the inferior humeral osteophyte often presenting with glenohumeral osteoarthritis. Entrapment may affect axillary nerve function and lead to changes in the teres minor muscle. Axillary neuropathy from an inferior humeral osteophyte may represent a contributing and treatable cause of pain in patients with glenohumeral osteoarthritis.

Abstract
PURPOSE The aims of this study were to evaluate the incidence of anchor penetration of the far cortex of the glenoid neck after arthroscopic Bankart repair and to compare the biomechanical properties of anchors in the 4- and 5:30- to 6-o'clock positions on the glenoid. METHODS Twelve (6 matched pairs) fresh-frozen human cadaveric shoulders were used to simulate arthroscopic Bankart repair in the lateral decubitus position. The most inferior anchor (5:30 to 6 o'clock) and that above it (4 o'clock) were inserted via the anteroinferior portal on the glenoid using the standard technique. After both anchor insertions, anchor perforation of the glenoid far cortex was identified. Biomechanical properties were measured to determine cyclic displacement of anchors at 100 and 500 cycles, stiffness, yield load, and ultimate failure strength. RESULTS All 12 suture anchors (100%) at 5:30 to 6 o'clock penetrated throughout the far cortex, whereas only 4 anchors (33%) at 4 o'clock did so (P = .005). The mean distance the anchor tip traveled into far cortex was significantly longer at 5:30 to 6 o'clock than at 4 o'clock (6.8 ± 1.6 mm v 2.0 ± 1.6 mm, P = .001). In terms of mechanical strength, anchors at 5:30 to 6 o'clock had greater 100- and 500-cycle mean displacements than those at 4 o'clock (3.0 ± 0.5 mm v 2.5 ± 0.3 mm, P = .018 for 100 cycles; 3.5 ± 0.7 mm v 2.8 ± 0.3 mm, P = .018 for 500 cycles), although no differences in ultimate failure strength after cyclic loading were found between 2 positions (133.4 ± 40.3 and 133.7 ± 29.2 N, respectively; P = .985). CONCLUSIONS For arthroscopic Bankart repair, insertion of the most inferior anchor via the anteroinferior portal with standard technique, in the lateral decubitus position, carries a high risk of perforating the inferior far cortex of the glenoid (100% in our study). This may result in mechanical weakness of the most inferior repair specifically in the early postoperative period. CLINICAL RELEVANCE Perforation of the glenoid far cortex by the most inferior anchor and its mechanical weakness should be taken into consideration. Further study is needed to improve surgical technique to place the most inferior anchor in an optimal position by arthroscopy.

Abstract
PURPOSE This study examined the clinical results of an arthroscopic simple pleated capsular shift to treat severe recurrent anterior dislocation of the shoulder. METHODS Twenty-four patients with anterior labroligamentous periosteal sleeve avulsion or advanced lesions who underwent an arthroscopic simple pleated capsular shift were included in this study. To create an arthroscopic simple pleated capsular shift, redundant capsules, including glenohumeral ligaments, were brought at least 1 cm lateral and 1 cm inferior and shifted to the prepared glenoid. Four sutures were made at the 5, 4, 3, and 1-2 o'clock positions with four anchors. Clinical results were evaluated using a visual analog scale (VAS), ROWE scores, active motion, and return to activity. Statistical analyses were carried out using paired t tests. RESULTS Three out of 24 patients had complaints. Two patients with recurrent instability underwent a repeat surgery, while the other patient complained of a stiff shoulder. There was a significant improvement in the VAS and ROWE scores post-operatively versus pre-operatively (p < 0.001, p < 0.001, respectively), but no significant differences in active motion except for external rotation, which decreased post-operatively (p = 0.02). CONCLUSIONS In patients with severe recurrent anterior dislocation, simple pleated capsular shift provided a reliable result. Four capsular shift sutures, 1 cm lateral and 1 cm inferior from the glenoid, were sufficient to reduce shoulder joint volume and restore stability. The arthroscopic capsular shift could be an alternative method in the case of no available labral lesion for repair. LEVEL OF EVIDENCE Case series, Therapeutic, Level IV.

Abstract
PURPOSE The purpose of this study was to evaluate a new all-arthroscopic technique in the management of recalcitrant globally stiff frozen shoulders. This adopts an initial extra-articular approach followed by intra-articular entry to perform a 360° capsular release. METHODS Ten patients with global adhesive capsulitis were prospectively evaluated. All patients had not improved after undergoing a minimum of 6 months of physiotherapy, and 5 received intra-articular injections of steroids. The mean age was 47 years (range, 33 to 56 years). Patients were examined preoperatively and postoperatively for range of motion. A Constant score and visual analog scale score for pain were recorded. We described an all-arthroscopic technique by entering the subacromial space laterally and opening the rotator interval from the outside in, followed by a complete 360° capsular release and biceps tenotomy. RESULTS The mean follow-up was 42 months (range, 18 to 90 months), and the mean Constant score improved from 21 to 72 (P < .01). Preoperative abduction improved from a mean of 40° to 165°, elevation improved from 55° to 175°, and external rotation improved from 6° to 58°. The visual analog scale pain score improved from 7 to 1.6, and all patients reported an excellent outcome after surgery. There were no complications particularly regarding axillary nerve injury, fracture, or infection. CONCLUSIONS This study shows a combined extra-articular and intra-articular approach that is controlled and anatomic and achieves excellent results that were maintained at the midterm. The technique permits anatomic debridement of the rotator interval, enabling excellent intra-articular access, a circumferential capsular release, and biceps tenotomy. There were no complications, and no manipulations were required, which pose a risk of creating soft-tissue lesions, fractures, or dislocations. We recommend this 360° capsular release technique for releasing globally stiff shoulders where the surgeon is experienced in arthroscopy.

Abstract
Adhesive capsulitis is a common and challenging condition to treat. Arthroscopic capsular release is usually contemplated when conservative treatment fails or when there is severe and/or chronic loss of range of motion. This procedure can be difficult to perform because of difficult access to the joint, poor visualization, and loss of working space from retraction of the joint capsule. The articular surfaces and the axillary nerve are also at higher risk of injury. Arthroscopic scissors, shavers, and electrocautery are typically used to perform the capsular release. To perform a safer and more precise arthroscopic shoulder capsular release, a creative and innovative use of a flexible hip arthroscopy radiofrequency ablator is described.

Abstract
INTRODUCTION Paralabral ganglion cysts of the shoulder are rare, and their pathogenesis is similar to that of meniscal cysts. The paralabral cysts are most frequently reported along the posterior, superior, and anterior aspects of the glenohumeral joint and are uncommon inferiorly to the joint. These cysts rarely become evident clinically, unless they cause compression of surrounding structures, i.e. nerve. PATIENTS AND METHODS We report a retrospective series of five patients with inferior paralabral ganglion cysts of the shoulder without compression of the surrounding nerve which were treated during the period from March 2007 to December 2009. All these patients presented with only chronic shoulder pain as their chief complaint, and preoperative MRI showed the cyst over the inferior aspect of a torn glenoid labrum. All patients were treated by arthroscopic cystic decompression with labrum repair. All patients were re-evaluated with MRI performed at an average of 15 months postoperatively. The clinical outcome, including the Constant score, was assessed for all patients at a median of 16 months postoperatively. RESULTS All the five patients had remission of pain and were satisfied with the shoulder function. The postoperative MRI in all patients showed no labral cyst recurrence. The median Constant score improved from a preoperative level of 81.5 points to 98.0 points at last follow-up. CONCLUSION This study demonstrates that, in the absence of any nerve compression symptoms around the shoulder joint, inferior paralabral cysts with labral tear also be considered in the differential diagnosis of chronic shoulder pain. Arthroscopic repair of the cyst with repair of the labrum can lead to the disappearance of symptoms. Knowledge of this clinical condition and its imaging features is critical for a correct diagnosis of this uncommon cause of chronic shoulder pain. LEVEL OF EVIDENCE Level IV. Retrospective therapeutic study.

Abstract
The management of osteoarthritis of the shoulder in young, active patients is a challenge, and the optimal treatment has yet to be completely established. Many of these patients wish to maintain a high level of activity, and arthroplasty may not be a practical treatment option. It is these patients who may be excellent candidates for joint-preservation procedures in an effort to avoid or delay joint replacement. Several palliative and restorative techniques are currently optional. Joint debridement has shown good results and a combination of arthroscopic debridement with a capsular release, humeral osteoplasty, and transcapsular axillary nerve decompression seems promising when humeral osteophytes are present. Currently, microfracture seems the most studied reparative treatment modality available. Other techniques, such as autologous chondrocyte implantation and osteochondral transfers, have reportedly shown potential but are currently mainly still investigational procedures. This paper gives an overview of the currently available joint preserving surgical techniques for glenohumeral osteoarthritis.

Abstract
Multidirectional shoulder instability is defined as symptomatic instability in two or more directions. Instability occurs when static and dynamic shoulder stabilizers become incompetent due to congenital or acquired means. Nonspecific activity-related pain and decreased athletic performance are common presenting complaints. Clinical suspicion for instability is essential for timely diagnosis. Several examination techniques can be used to identify increased glenohumeral translation. It is critical to distinguish increased laxity from instability. Initial management begins with therapeutic rehabilitation. If surgical management is required, capsular plication has been used successfully. Advanced arthroscopic techniques offer several advantages over traditional open approaches and may have similar outcomes. The role of rotator interval capsular plication is controversial, but it may be used to augment capsular plication in patients with specific patterns of instability. Despite encouraging results, outcomes remain inferior to those associated with traumatic unidirectional instability.

Abstract
Symptomatic axillary nerve compression is rare yet results in debilitating pain, weakness, and decreased athletic performance in some patients. If nonoperative modalities fail, surgical intervention is necessary to reduce symptoms and avoid functional decline. Traditionally, open techniques have been described to decompress the axillary nerve and are reported to provide satisfactory results. Similar to suprascapular nerve decompression, recent advances have provided the opportunity to develop all-arthroscopic axillary nerve decompression techniques. Although direct comparisons between open and arthroscopic techniques do not exist, arthroscopic axillary nerve decompression may provide some benefits over open techniques. Therefore we present a technique and early results for all-arthroscopic trans-capsular axillary nerve decompression.

Abstract
Glenohumeral arthrosis frequently results in substantial discomfort and activity limitations. Shoulder arthroplasty has been shown to provide reliable pain relief under these circumstances in older, less active populations. Younger patients, however, who desire to continue participation in high-demand activities, may not be optimal candidates for glenohumeral arthroplasty. Arthroscopic debridement has been reported to provide incomplete symptomatic relief in this cohort of patients. It is evident from cadaveric studies that the axillary nerve runs in close proximity to the inferior glenohumeral capsule. An inferior humeral osteophyte of sufficient size may compress the axillary nerve and potentially contribute to posterior shoulder pain in a manner similar to quadrilateral space syndrome. Therefore we present a technique for and early results of the arthroscopic management of glenohumeral arthrosis in young, high-demand patients. This technique combines traditional glenohumeral debridement and capsular release with inferior humeral osteoplasty and arthroscopic transcapsular axillary nerve decompression. In the appropriate patient, these additions may provide symptomatic relief that is greater than that with simple debridement alone.

Abstract
BACKGROUND Interscalene brachial plexus block (IBPB) is the gold standard for perioperative pain management in shoulder surgery. However, a more distal technique would be desirable to avoid the side effects and potential serious complications of IBPB. Therefore, the aim of the present study was to develop and describe a new method to perform an ultrasound-guided specific axillary nerve block. METHODS After initial investigations, 12 healthy volunteers were included. We performed an in-line ultrasound-guided specific axillary nerve block by injecting 8 ml local anesthetic (lidocaine 20 mg/ml) after placing the tip of a nerve stimulation needle cranial to the posterior circumflex humeral artery in the neurovascular space bordered by the teres minor muscle, the deltoid muscle, the triceps muscle and the shaft of the humerus. Needle placement was aided by simultaneous nerve stimulation. We assessed sensory (pinprick and cold stimulation) and motor (active resistive force) block of the axillary nerve before, 15, 30, 60, 90 and 120 min after performing the block and every 30 min until termination of the block. RESULTS All 12 volunteers demonstrated sensory block of the axillary nerve and 10 volunteers demonstrated complete motor block. Even though it was difficult to directly visualize the axillary nerve, the block was easy to perform with easily recognizable ultrasonographic landmarks. Block duration was approximately 120 min. CONCLUSIONS We describe a new ultrasound-guided technique to specifically block the axillary nerve. The potential clinical role of this new block remains to be determined.

Abstract
Recurrent posterior instability of the shoulder can be difficult to diagnose and technically challenging to treat. Although not as common as anterior instability, recurrent posterior shoulder instability is prevalent among certain demographic and sporting groups, and may be overlooked if one is not aware of the typical examination and radiographic findings. The diagnosis itself can be difficult as patients typically present with vague or confusing symptoms, and treatment has evolved from open to arthroscopic surgical techniques. This article is intended to review the anatomy and biomechanics associated with posterior shoulder instability, to discuss the pathogenesis and presentation of posterior instability, and to describe the variety of treatment options and clinical results.

Abstract
The axillary nerve is invariably reported to be one of the most commonly injured nerves during surgical procedures of the shoulder, and the importance of protecting it cannot be overemphasized. Many researchers have tried to identify safe regions, but the results vary among published studies. The axillary nerve may also be injured during acute trauma to the shoulder or by chronic repeated trauma as has been described in the quadrilateral space syndrome. The nerve injury may occur together with shoulder dislocation and rotator cuff tear, thus comprising the so-called "unhappy triad" of the shoulder joint. Simple attention to potential variations in the origin and course of the axillary nerve and its relationship to the shoulder capsule and having a precise knowledge of "safe zones" during operations can enhance clinical outcomes. The objective of this review, therefore, is to discuss the surgical anatomy of the axillary nerve and further emphasize the clinical importance of the its injury following shoulder trauma.

Abstract
PURPOSE The purposes of this study were to examine the morphologic features of the axillary nerve and its relation to the glenoid under an arthroscopic setup, and to determine the changes in nerve position according to different arm positions. METHODS Twenty-three fresh-frozen fore-quarter cadaveric shoulder specimens were used for evaluations in an arthroscopic setup with the lateral decubitus position. The main trunk of the axillary nerve with or without some of its branches was exposed after careful arthroscopic dissection. Morphologic features and the course of the axillary nerve from the anterior and posterior portals were documented. The closest distances from the glenoid rim were measured with a probe by use of a distance range system. The changes in nerve position were determined in 4 different arm positions. At the end of arthroscopic examination, the nerves were marked and verified by open dissections. RESULTS The axillary nerve appeared in the joint near the inferior edge of the subscapularis muscle. With reference to the inferior glenoid rim horizontally, the nerve had a mean running angle of 23 degrees (range, 14 degrees to 41 degrees; SD, 8 degrees ). The closest points from the glenoid were between the 5:30- and 6:00-o'clock position (right) or 6:00- and 6:30-o'clock position (left). The closest distance range varied from 10 to 25 mm in the neutral arm position. The abduction-neutral position resulted in the greatest distance between the inferior glenoid and the nerve. CONCLUSIONS The abduction-neutral rotation position was the optimal position for minimizing axillary nerve injuries, because it resulted in the greatest distance between the inferior glenoid and the nerve. CLINICAL RELEVANCE Knowledge of the anatomy of the axillary nerve aids the shoulder surgeon in avoiding nerve injury during arthroscopic procedures. Abduction-neutral rotation may be more helpful for arthroscopic surgeons performing procedures in the anteroinferior glenoid with the nerve being farther away from the working field.
