Abstract
Background Distal clavicle excision for acromioclavicular joint (ACJ) pathology is currently the mainstay of surgical management in patients with symptoms refractory to nonoperative treatment. There have been few high quality studies outlining the efficacy of arthroscopic excision of the distal clavicle as a single procedure in patients with isolated disease. Aim To characterize function and pain outcomes in patients undergoing arthroscopic distal clavicle excision by utilizing stringent inclusion criteria to isolate ACJ pathology. Methods Prospective data collection was undertaken with a minimum two year follow-up of 59 patients undergoing arthroscopic distal clavicle excision for ACJ osteoarthritis or distal clavicle osteolysis. Stringent eligibility criteria were applied to each patient. Data collection consisted of demographic data, clinical assessment of range of motion, and patient-reported outcome measures (PROMs), utilizing the standardized Shoulder Pain and Disability Index (SPADI) and the Visual Analogue (VAS) score to characterize pain. Furthermore, time to return to work and sport and a subjective measure of how 'normal' the shoulder felt were assessed. Data was recorded preoperatively, and at six, 12, and 24 months postoperatively. Statistical analysis was conducted utilizing institutional support. Results Statistically significant improvements in range of motion measurements (abduction, forward elevation and external rotation), and PROMs (SPADI and VAS scores) were reported. VAS scores reduced from an average of 8.20 preoperatively to 3.39 (P < .001), 2.13 (P < .001) and 1.36 (P < .001) at 6, 12, and 24 month follow-up, respectively. Similarly, SPADI scores reduced from an average of 62.65 preoperatively to 19.96 (P < .001), 12.6 (P < .001), and 6.13 (P < .001) at 6, 12, and 24 months, respectively. The majority of patients were able to return to sport and work, within an average time of 1.72 and 3.02 months. Conclusion In patients who presented with isolated ACJ pathology, arthroscopic distal clavicle excision, as a single procedure, results in statistically significant improvements in PROMs and functional outcomes.

Abstract
Background Acromioclavicular joint (ACJ) Osteoarthritis (OA) is very common in the general population. Despite this, there is little mention of concomitant glenohumeral and ACJ arthropathy in the literature, and no documented incidence of symptomatic ACJ OA post total shoulder arthroplasty (TSA). We present the incidence and timescale of the problem, and the response to treatments. Methods Patients who had developed ACJ-related symptoms following a TSA were retrieved from a prospectively collected database. It was determined that these symptoms were not related to the prosthesis or other non-ACJ pathology. Results There were 230 primary anatomic total shoulder replacements carried out over a 9-year period, with 219 with adequate follow-up for analysis. Thirty-five (16%) developed a symptomatic ACJ. The majority developed symptoms within the first two years however there was one patient who developed symptoms eight years later. Twenty six percent of patients responded to a period of rest. Seventy one percent had a cortisone injection in the ACJ and in 44% of patients this was effective. Twelve (34%) patients had an arthroscopic excision of distal clavicle with good resolution of the symptoms. Discussion ACJ symptoms following a total shoulder replacement appears more common than thought and can be treated successfully.

Abstract
ABSTRACT Weightlifting associated shoulder injuries have seen a dramatic rise in the last 20 years. Distal clavicular osteolysis, coined weightlifter's shoulder, is one such condition caused by repetitive microtrauma to the distal clavicle with subsequent, painful development of bony erosions and resorption of the distal clavicle. Diagnosis, treatment, and prevention of this condition can be challenging. In this article, we highlight evidence-based clinical recommendations for the diagnosis and management of distal clavicular osteolysis, including specific considerations for atraumatic and posttraumatic etiologies, to help clinicians better care for their patients. Activity modification and rehabilitation are the mainstays of the initial treatment. Adjuvant treatments, such as injections or surgery, may be required in refractory cases or in certain patient populations. Early recognition and treatment of weightlifter's shoulder is essential to prevent progression to acromioclavicular joint pathology or instability and to allow for continued participation in sport-specific activities.

Abstract
Background The rate of complications of open compared to arthroscopic distal clavicle excision remain poorly studied. Therefore, the purpose of this investigation was to (1) Identify most recent national trends in the usage of open vs. arthroscopic approaches for distal clavicle excision (DCE) from 2007 to 2017; (2) to identify and compare the complication rates for both approaches, and to identify patient-specific risk factors for complications; (3) to identify and compare the revision rate for both approaches; and (4) to identify and compare the reimbursement of each approach. Methods The PearlDiver database was reviewed for patients undergoing DCE from 2007 to 2017. Patients were stratified into 2 cohorts: those undergoing arthroscopic DCE (n = 8933) and those undergoing open DCE (n = 2295). The rate of postoperative complications within 90 days was calculated and compared. The revision rate and reimbursement of the arthroscopic and open approach were compared. Statistical analysis included chi-square testing to compare the rates of postoperative complications and multivariate logistic regression analysis to identify risk factors for complications within 90 days. Results were considered significant at P < .05. Results The percentage of DCEs performed arthroscopically has significantly increased from 53.9% in 2007 to 69.8% in 2016, with a concomitant decrease in the use of open DCE from 46.1% in 2007 to 30.2% in 2016. The open approach was associated with significantly more postoperative complications, including a significantly greater incidence of surgical site infection (1.9% vs. 0.3%; P < .001), wound disruption (0.3% vs. 0.1%; P < .001), hematoma (0.9% vs. 0.2%; P = .001), and transfusion (0.6% vs. 0.1%; P < .001), than arthroscopic DCE. Several risk factors, including open approach, diabetes, heart disease, tobacco use, chronic kidney disease, and female gender, were identified as independent risk factors for complications after DCE. There was no significant difference in revision rate between open and arthroscopic approaches (P = .126). The reimbursement of open and arthroscopic DCE procedures were comparable, with median reimbursements of $5408 and $5,447, respectively (P = .853). Conclusion Both arthroscopic and open DCE techniques were found to have similar reimbursement amounts, with a low rate of complications, although the open technique had a higher rate of early complications such as surgical site infection. Over the study period, there was an increase in the utilization of arthroscopic DCE, while the incidence of the open technique remained constant.

Effect Size in Surgical Intervention Into Shoulder: What Procedures Are Game Changers and What Are Not? JOURNAL OF THE AMERICAN ACADEMY OF ORTHOPAEDIC SURGEONS GLOBAL RESEARCH AND REVIEWS 2020; 4:JAAOSGlobal-D-20-00022. [PMID: 32440636 PMCID: PMC7209793 DOI: 10.5435/jaaosglobal-d-20-00022] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Accepted: 02/16/2020] [Indexed: 12/31/2022]
Abstract
A number of surgical procedures are performed to treat a variety of shoulder pathologies. What is currently not understood is which of these surgical interventions provide the most improvement in patient-reported pain and function. Questions We aimed to determine, from a patient's perspective, which were the most effective commonly performed surgical procedures for disorders of the shoulder and which were not. Methods This study was a retrospective analysis of prospectively collected data from patients who underwent shoulder surgery by a single surgeon. To be included, at least 20 patients needed to have undergone that procedure and completed a questionnaire evaluating their shoulders function preoperatively and 6 months postoperatively. The primary outcome was change in response to the question "how is your shoulder overall?" Effect size is reported as Cohen's d (standardized mean difference). Results Two thousand two hundred six surgical procedures in 13 categories met the inclusion criteria. All procedures were associated with improvements in the patient-ranked overall shoulder status at 6 months (P < 0.01 to P < 0.0001). Reverse total shoulder arthroplasty (RTSA) provided the greatest effect size (improvement) in the overall shoulder status (d = 3.14, 95% CI, 2.49 to 3.79), followed by total shoulder arthroplasty (d = 2.60, 95% CI, 2.10 to 3.10) and capsular release (d = 1.41, 95% CI, 1.08 to 1.75). RTSA provided the greatest effect size in patient-reported shoulder pain, whereas capsular release provided the greatest effect size in patient-reported shoulder function. Acromioclavicular joint resection (d = 1.22, 95% CI, 0.56 to 1.88) and acromioplasty (d = 1.29, 95% CI, 0.96 to 1.61) provided the least effect size overall. Conclusion All shoulder surgical procedures in this study provided a notable patient-perceived therapeutic benefit in a relatively short period of time (6 months). RTSA, total shoulder arthroplasty, and capsular release are the most effective procedures. Acromioplasty and acromioclavicular resection are the least effective.

Abstract
BACKGROUND The objective of the present study was to perform a systematic review and meta-analysis of randomized controlled trials looking at the effect of distal clavicle resection in patients undergoing rotator cuff repair (RCR). METHODS A systematic literature search was undertaken to identify randomized controlled trials looking at RCR +/- distal clavicle resection. Primary clinical outcome measures included in the meta-analysis were American Shoulder Elbow Society (ASES) score, pain on visual analogue scale and range of motion in forward elevation. RESULTS The systematic review identified three studies with a total of 203 participants. Those who underwent distal clavicle resection in conjunction with RCR had worse pain and acromioclavicular joint tenderness at 3-month follow-up. This difference, however, was not observed at the 24-month follow-up. The mean difference (95% confidence interval) for the ASES score was 0.45 (-3.67 to 4.58) and pain on visual analogue scale was - 0.27 (-0.70 to 0.16). CONCLUSIONS Routine distal clavicle resection in the setting of rotator cuff repair does not result in improved outcomes for patients with no difference being observed at 24 months post surgery. The results of our systematic review and meta-analysis do not support routine distal clavicle resection when performing RCR.

Abstract
BACKGROUND Acromioclavicular joint arthritis is a common, painful, and often missed diagnosis, and it often accompanies other shoulder conditions such as rotator cuff disease. Whether distal clavicle resection is important to perform in patients undergoing surgery for rotator cuff tears and concomitant acromioclavicular joint arthritis is controversial. QUESTIONS/PURPOSES The purpose of this study was to perform a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the effect of distal clavicle resection on (1) outcome scores; (2) shoulder ROM, joint pain or tenderness, and joint instability; and (3) risk of reoperation among patients treated surgically for rotator cuff tears who had concomitant acromioclavicular joint arthritis. METHODS We systematically searched the PubMed, EMBASE, and Cochrane databases to find RCTs that met our eligibility criteria, which, in summary, (1) compared rotator cuff repair plus distal clavicle resection with isolated rotator cuff repair for patients who sustained a full- or partial-thickness rotator cuff tear and concomitant acromioclavicular joint arthritis; and (2) the followup period was at least 2 years. Two reviewers screened the studies, extracted the data and evaluated the methodological quality, and performed data analysis. Statistical heterogeneity among studies was quantitatively evaluated with the I index. No heterogeneity was detected (I = 0%; p = 0.75) in terms of acromioclavicular joint pain or tenderness, Constant score, forward flexion, external rotation, and risk of reoperation, so fixed-effect models were used in these endpoints. Heterogeneity was moderate for the American Shoulder and Elbow Surgeons (ASES) score (I = 53%; p = 0.12) and low for the visual analog scale (VAS) score (I = 35%; p = 0.22), so random-effect models were used in these endpoints. Subgroup analysis was stratified by the symptom of acromioclavicular joint arthritis. Three RCTs with 208 patients were included. We evaluated the risk of bias using the Cochrane risk-of-bias tool; in aggregate, the three RCTs included showed low to intermediate risk, although not all parameters of the Cochrane tool could be assessed for all studies. RESULTS There was no difference between the distal clavicle resection plus rotator cuff repair group and the isolated rotator cuff repair group in ASES score (mean difference =1.41; 95% confidence interval [CI], -3.37 to 6.18; p = 0.56) nor in terms of the VAS score and Constant score. Likewise, we found no difference in ROM of the shoulder (forward flexion, internal rotation, and external rotation) or acromioclavicular joint pain or tenderness between the groups (pooled results of acromioclavicular joint pain or tenderness: risk ratio [RR], 1.59; 95% CI, 0.67-3.78; p = 0.30). Acromioclavicular joint instability was only detected in the rotator cuff repair plus distal clavicle resection group. Finally, we found no difference in the proportion of patients undergoing repeat surgery between the study groups (pooled results of risk of reoperation for the rotator cuff repair plus distal clavicle resection and isolated rotator cuff repair: one of 52 versus two of 78; RR, 0.86; 95% CI, 0.11-6.48; p = 0.88). CONCLUSIONS Distal clavicle resection in patients with rotator cuff tears did not result in better clinical outcome scores or shoulder ROM and was not associated with a lower risk of reoperation. Distal clavicle resection might cause acromioclavicular joint instability in patients with rotator cuff tears and concomitant asymptomatic acromioclavicular joint arthritis. Arthroscopic distal clavicle resection is not recommended in patients with rotator cuff tears and concomitant acromioclavicular joint arthritis. Additional well-designed RCTs with more participants, long-term followup, and data on patient-reported outcomes are needed. LEVEL OF EVIDENCE Level I, therapeutic study.

Abstract
PURPOSE (1) Define the epidemiologic trend of distal clavicle excision (DCE) for acromioclavicular (AC) joint arthritis among board-eligible orthopaedic surgeons in the United States, (2) describe the rates and types of reported complications of open and arthroscopic DCE, and (3) evaluate the effect of fellowship training on preferred technique and reported complication rates. METHODS The American Board of Orthopaedic Surgery (ABOS) database was used to identify DCE cases submitted by ABOS Part II Board Certification examination candidates. Inclusion criteria were predetermined using a combination of ICD-9 and CPT codes. Cases were dichotomized into 2 groups: open or arthroscopic DCE. The 2 groups were then analyzed to determine trends in annual incidence, complication rates, and surgeon fellowship training. RESULTS From April 2004 to September 2013, there were 3,229 open and 12,782 arthroscopic DCE procedures performed and submitted by ABOS Part II Board Eligible candidates. Overall, the annual incidence of open DCE decreased (78-37 cases per 10,000 submitted cases, P = .023). Although the annual number of arthroscopic DCE remained steady (1160-1125, P = .622), the percentage of DCE cases performed arthroscopically increased (65%-79%, P = .033). Surgeons without fellowship training were most likely to perform a DCE via an open approach (31%) whereas surgeons with sports medicine training were more likely to perform DCE arthroscopically compared with other fellowship groups (88%, P < .001). Open DCE was associated with a higher surgical complication rate overall when compared with arthroscopic DCE (9.4% vs 7.6%, respectively; P < .001). When compared with other fellowship-trained surgeons, sports medicine surgeons maintained a lower reported surgical complication rate whether performing open or arthroscopic DCE (5.5%, P = .027). CONCLUSIONS In recent years, open management of AC joint arthritis has declined among newly trained, board-eligible orthopaedic surgeons, possibly because of an increased complication rate associated with open treatment. Fellowship training was significantly associated with the type of treatment (open vs arthroscopic) rendered and complication rates. LEVEL OF EVIDENCE Level IV, case series.

Abstract
BACKGROUND Shoulder pain secondary to acromioclavicular joint pain is a common presentation in primary and secondary care but is often poorly managed as a result of uncertainty about optimal treatment strategies. Osteoarthritis is the commonest cause. Although acromioclavicular pain can be treated non-operatively and operatively, there appears to be no consensus on the best practice pathway of care for these patients, with variations in treatment being common place. The present study comprises a scoping review of the current published evidence for the management of isolated acromioclavicular pain (excluding acromioclavicular joint dislocation). METHODS A comprehensive search strategy was utilized in multiple medical databases to identify level 1 and 2 randomised controlled trials, nonrandomised controlled trials and systematic reviews for appraisal. RESULTS Four systematic reviews and two randomised controlled trials were identified. No direct studies have compared the benefits or risks of conservative versus surgical management in a controlled environment. CONCLUSIONS High-level studies on treatment modalities for acromioclavicular joint pain are limited. As such, there remains little evidence to support one intervention or treatment over another, making it difficult to develop any evidenced-based patient pathways of care for this condition.Level of evidence: 2A.

Abstract
BACKGROUND Symptomatic acromioclavicular joint (ACJ) lesions are a common cause of shoulder complaints that can be treated successfully with both conservative and surgical methods. There are several operative techniques, including both open and arthroscopic surgery, for excising the distal end of the clavicle. Here, we present a new modified arthroscopic technique for painful osteoarthritis of the ACJ and evaluate its clinical outcomes. Our hypothesis was that 4- to 7-mm resection of the distal clavicle in an en bloc fashion would have several advantages, including no bony remnants, maintenance of stability of the ACJ, and reduced prevalence of heterotopic ossification, in addition to elimination of the pathologic portion of the distal clavicle. MATERIALS AND METHODS 20 shoulders of 20 consecutive patients with painful and isolated osteoarthritis of the ACJ who were treated by arthroscopic en bloc resection of the distal clavicle were included in the study. There were 10 males and 10 females with an average age of 56 years (range 42-70 years). The mean duration of followup was 6 years and 2 months (range 4-8 years 10 months). The results were evaluated using the University of California Los Angeles (UCLA) shoulder rating score. RESULTS The overall UCLA score was 13.7 preoperatively, which improved to 33.4 postoperatively. All subscores were improved significantly (P < 0.001). There were no specific complications at the latest followup. CONCLUSION It is critical in this procedure to resect the distal clavicle evenly from superior to inferior in an en bloc fashion without any small bony remnants and to preserve the capsule and acromioclavicular ligament superoposteriorly. This arthroscopic procedure is a reliable and reproducible technique for painful osteoarthritis of the ACJ lesions in active patients engaged in overhead throwing sports and heavy labor.

Abstract
BACKGROUND The failure of subacromial decompression may be attributed to persistent symptoms of acromioclavicular joint (ACJ) arthritis, while inferior clavicular spurs of the ACJ may be associated with failed healing of repaired rotator cuffs. PURPOSE To evaluate the clinical effectiveness of arthroscopic distal clavicle resection (DCR) in patients with rotator cuff tears and concomitant asymptomatic radiological ACJ arthritis. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS A total of 78 patients with rotator cuff tears in addition to radiological and asymptomatic ACJ arthritis who were scheduled for arthroscopic rotator cuff repair were prospectively randomized into 2 groups. Patients underwent arthroscopic rotator cuff repair with acromioplasty. Patients in group 1 (39 patients) underwent additional arthroscopic DCR, while patients in group 2 (39 patients) did not. Clinical outcomes of the 2 groups were compared using the visual analog scale (VAS) for pain, range of motion, Constant score, and American Shoulder and Elbow Surgeons (ASES) score up to at least 24 months. The structural integrity of repaired rotator cuffs was assessed using ultrasonography, computed tomography arthrography, or MRI at least 6 months after surgery. To evaluate ACJ instability, weighted stress radiography of the ACJ was studied at 6 and 12 months postoperatively. RESULTS Patients in both groups showed significant improvement in the VAS score and all functional scores at final follow-up (mean, 29.2 months; range, 24-46 months) without significant differences between the 2 groups (P > .05). Results (mean ± SD) for preoperative group 1/group 2 and postoperative group 1/group 2 were as follows, respectively: 7.2 ± 1.8/6.1 ± 1.9 (P = .02) and 0.6 ± 1.8/0.6 ± 0.9 (P = .97) for the VAS score, 74.1 ± 5.7/73.8 ± 8.0 (P = .87) and 96.3 ± 5.7/95.7 ± 4.6 (P = .77) for the Constant score, and 47.0 ± 10.3/50.8 ± 14.1 (P = .22) and 91.5 ± 15.5/94.5 ± 11.8 (P = .55) for the ASES score. Failed cuff healing occurred in 9 patients (23%) in group 1 and 10 patients (26%) in group 2, with no significant difference (P = .95). In group 1, there were 2 patients (5.0%) with ACJ subluxation on weighted stress radiography at 6 months postoperatively. These patients complained of gross protrusion and ACJ tenderness. CONCLUSION Preventive arthroscopic DCR in patients with rotator cuff tears and concomitant asymptomatic radiological ACJ arthritis did not result in better clinical or structural outcomes, and it did lead to symptomatic ACJ instability in some patients. Preventive arthroscopic DCR is not recommended in patients with radiological but asymptomatic ACJ arthritis. Further long-term follow-up is needed to confirm the development of symptoms in ACJ arthritis.

Abstract
PURPOSE The purpose of this study was to evaluate and quantify the demographic characteristics of patients undergoing open and arthroscopic distal clavicle excision (DCE) in the United States while also describing changes in practice patterns over time. METHODS Patients who underwent DCE from 2004 to 2009 were identified by Current Procedural Terminology (CPT) codes in a national database of orthopaedic insurance records. The year of procedure, age, sex, geographic region, and concomitant rotator cuff repair or subacromial decompression (SAD) were recorded for each patient. Results were reported as the incidence of procedures identified per 10,000 patients searched in the database. RESULTS Between 2004 and 2009, 73,231 DCEs were performed; 74% were arthroscopic and 26% were open. The incidence of arthroscopic DCE increased from 37.8 in 2004 to 58.5 in 2009 (P < .001), whereas the incidence of open DCE decreased from 21.1 in 2004 to 14.1 in 2009 (P < .001). Sixty-one percent of DCEs were performed in men (P < .001). Women were more likely to undergo an arthroscopic procedure (P < .001). Arthroscopic DCE was most common in patients aged 50 to 59 years (P < .001). Open DCE was most common in patients aged 60 to 69 years (P < .001). Open rotator cuff repair and SAD were concomitantly performed in 38% and 23% of open DCEs, respectively. Arthroscopic rotator cuff repair and SAD were concomitantly performed in 33% and 95% arthroscopic DCEs, respectively. CONCLUSIONS This analysis of DCE using a private insurance database shows that arthroscopic DCEs progressively increased, whereas open DCEs concomitantly decreased between 2004 and 2009. The majority of DCEs were performed in men between the ages of 50 and 59 years. Both arthroscopic and open DCEs are frequently performed in conjunction with rotator cuff repair or SAD.

Abstract
PURPOSE. To compare the subjective outcome of acromioclavicular joint (ACJ) reconstruction using the modified Weaver-Dunn procedure versus the Surgilig synthetic ligament. METHODS. 55 patients aged 19 to 72 (mean, 42) years underwent ACJ reconstruction of Rockwood grade 3 (n=38), grade 4 (n=8), and grade 5 (n=9) using the modified Weaver-Dunn procedure (n=31) or the Surgilig synthetic ligament (n=24), based on the surgeon's preference. The mean period from injury to surgical treatment was 39 months. Subjective outcomes were assessed before and after surgery using the Oxford Shoulder score and Nottingham Clavicle score. The time required to return to work and sports was also recorded. RESULTS. After a mean follow-up period of 40 months, the mean Oxford Shoulder scores improved from 28 to 42 in the Weaver-Dunn group (p=0.009), and from 26 to 45 in the Surgilig group (p=0.007), whereas the respective mean Nottingham Clavicle scores improved from 53 to 81 (p=0.047) and from 51 to 93 (p=0.023). The Surgilig group achieved significantly better postoperative Oxford Shoulder score (p=0.008) and Nottingham Clavicle score (p=0.007), and could also return to work (14 vs. 6 weeks, p<0.001) and sports (25 vs. 12 weeks, p<0.001) sooner than the Weaver-Dunn group. Three patients in the Weaver- Dunn group and one patient in the Surgilig group had persistent pain and/or functional deficit with evidence of ACJ dislocation. CONCLUSION. Chronic ACJ reconstruction using the Surgilig synthetic ligament achieved better Oxford Shoulder score and Nottingham Clavicle score and earlier return to work and sports, compared with the modified Weaver-Dunn procedure.

Abstract
Certain arthropathies can distort the normal acromiohumeral relationship and make traditional anterolateral access to the proximal humerus for nailing difficult or impossible. This article presents a case of bilateral antegrade humeral nailing in which the Neviaser portal approach was used for humeral shaft fractures in a patient with distorted shoulder anatomy secondary to severe cuff tear arthropathy and rheumatoid arthritis. Based on a literature review, extending the traditional superomedial (Neviaser) portal to the shoulder to perform humeral nailing has never been described clinically. An 85-year-old woman with rheumatoid arthritis and bilateral cuff tear arthropathy presented after a mechanical fall from standing height with bilateral acute humeral shaft fractures. Preoperative fluoroscopy confirmed the inability to access the traditional starting point with an anterolateral approach due to a shield acromion resulting from cuff tear arthropathy and rheumatoid arthritis. Bilateral locked antegrade humeral nails were successfully placed through a 3-cm incision just off the medial border of the acromion and directly posterior to the acromioclavicular joint (the extended Neviaser portal approach). Postoperatively, the patient demonstrated early evidence of clinical and radiographic union. She was able to return to her preinjury function level, with an active range of motion comparable with her baseline. The Neviaser portal approach to antegrade humeral nailing is an effective solution to diaphyseal humeral fractures when access to the traditional anterolateral proximal humeral starting port is not possible due to distorted shoulder anatomy.

Abstract
BACKGROUND Treatment for acromioclavicular (AC) joint pain may include distal clavicle excision (DCE). It is possible that DCE can disrupt the surrounding ligaments, leading to increased AC joint laxity. PURPOSE To determine the load to failure and stiffness of the AC joint after DCE and symmetric acromioclavicular joint resection (ACJR). STUDY DESIGN Controlled laboratory study. METHODS Specimens were randomly assigned to 1 of 2 groups: 1-cm DCE (n = 10) or symmetric (5-mm excision of acromion and distal clavicle) ACJR (n = 10). The specimens were loaded intact in the anterior-posterior plane to determine anteroposterior translation. This was repeated after surgery and compared. The specimens were loaded at 2 mm/s until clinical failure. Force and displacement were recorded, and stiffness was calculated. RESULTS The peak load to failure for the DCE group was 387.8 N (standard error of the mean [SEM], 31.4 N) and for the ACJR group was 468.5 N (SEM, 30.9 N) (P = .035). The average stiffness for the DCE group was 35.2 N/mm (SEM, 2.5 N/mm) and for the ACJR group was 37.4 N/mm (SEM, 2.3 N/mm) (P = .11). There was no significant difference in the anteroposterior translation before and after resection for either group (P > .05). CONCLUSION This cadaveric study demonstrates that the anterior-posterior load to clinical failure of the AC joint after 5 mm of resection from the distal clavicle and medial acromion is significantly greater than 1 cm of the resected distal clavicle alone. CLINICAL RELEVANCE Performing ACJR may improve joint stability, leading to fewer complications when compared with DCE.

Abstract
BACKGROUND Injection to the acromioclavicular (AC) joint can be both diagnostic and therapeutic. PURPOSE The purpose of this study was to evaluate the accuracy of in vivo AC joint injections. STUDY DESIGN Case series; Level of evidence, 4. METHODS Thirty patients with pain localized to the AC joint were injected with 1 mL of 1% lidocaine and 0.5 mL of radiographic contrast material (Isovue). Radiographs of the AC joint were taken after the injection. Each radiograph was reviewed by a musculoskeletal radiologist and graded as intra-articular, extra-articular, or partially intra-articular. RESULTS Of the 30 injections performed, 13 (43.3%) were intra-articular, 7 (23.3%) were partially articular, and 10 (33.3%) were extra-articular. When the intra-articular and the partially articular groups were combined, 20 patients (66.7%) had some contrast dye in the AC joint. CONCLUSION This study demonstrates that despite the relatively superficial location of the AC joint, the clinical accuracy of AC joint injections remains relatively low.

Abstract
PURPOSE Our objective was to evaluate the effectiveness of arthroscopic distal clavicle resection in cases presenting with pain and subtle instability after neglected grade II acromioclavicular (AC) joint dislocation. METHODS From February 1998 to May 2006, 17 patients with symptomatic AC instability following chronic grade II AC joint injury were studied. Sixteen patients were male and one female, with a mean age of 48 years. An all-arthroscopic procedure comprising disk removal and distal clavicle resection was performed in all cases. All patients were reviewed clinically, preoperatively and at final follow-up (mean 38 months) using the pain score on a visual analog scale and the Constant score. Strength was measured using an Isobex digital strength analyzer. Patient's personal satisfaction after the procedure was documented as excellent, good or poor. Postoperative AC joint radiographs were routinely obtained in all patients to measure the amount of clavicle resection. RESULTS Two patients underwent additional reconstructive surgery for disabling pain and dysfunction even after the arthroscopic resection procedure. The remaining 15 patients were analyzed. The pain scores improved significantly (p = 0.03). The mean pain score was 5.8 (range 5-9) before treatment and 1.6 (range 0-3) at follow-up. The Constant scores had improved significantly at the final follow-up (p = 0.001). The median Constant score increased from 46 (range 36-69) preoperatively to 71 (range 48-84) postoperatively. Strength had improved at the last follow-up. Eleven patients were satisfied and six were not satisfied with this procedure at the final follow-up. CONCLUSIONS Arthroscopic distal clavicle resection statistically improved the pain score, Constant score and strength for grade II AC injury with subtle distal clavicle instability. However, six patients (33.5 %) were not satisfied subjectively. This procedure seemed to be a reasonable initial treatment option with lower morbidity.

Abstract
BACKGROUND A prospective study was established to assess the effect of an intra-articular injection of corticosteroid and local anaesthetic into the acromioclavicular (AC) joint. METHODS Fifty-eight patients with isolated AC joint symptoms were included. Clinical tests were repeated immediately following the injection, as well as at 1-month follow-up. If symptoms failed to improve at this time, arthroscopic surgery was offered. All other patients were dismissed from standard care and contacted for this study. Both American Shoulder and Elbow Surgeons (ASES) and University of California at Los Angeles (UCLA) scores were obtained at final follow-up. RESULTS Sixteen patients had improved sufficiently. Between the 1 month and average final follow-up of 42 months, 1 patient had arthroscopic resection of the distal clavicle. Four of the 15 patients reported occasional mild pain. Average visual analogue scale (VAS) score for pain was 0.5 (0-3). Average ASES score was 94.1 (70-100) and average UCLA score was 33.9 (28-35). DISCUSSION Pain relief achieved with an injection into the AC joint has both a diagnostic and therapeutic value. The decrease of pain with clinical testing affirms the correct position of the injection. Only a minority of patients has sufficient pain relief from the injection at 1 month follow-up; however, this is sustained at the longer-term follow-up in the patients that have a positive reaction. CONCLUSION The diagnostic value of the injection of a local anaesthetic in the AC joint is immediate. Only 28% have a clear positive result at 1 month; but, this result is sustained at long-term follow-up. There were no complications.

Abstract
PURPOSE The purpose of this systematic review was to critically evaluate the available literature in an attempt to compare the outcome of open versus arthroscopic distal clavicle resection in the treatment of acromioclavicular joint pathology. METHODS From January 1966 to December 2008, Medline was searched for the following key words: "acromioclavicular joint arthritis," "acromioclavicular osteolysis," "distal clavicle excision," "acromioclavicular joint excision," "Mumford," and "clavicle." Inclusion criteria included studies that compared the outcome of open versus arthroscopic distal clavicle resection. Studies that could not be translated into the English language or were not published in a peer-reviewed journal were excluded. Data were abstracted from the studies, including patient demographics, surgical procedure, rehabilitation, strength, range of motion, and clinical scoring system. RESULTS Seventeen studies met the inclusion criteria, including 2 Level II studies, 1 Level III and 14 Level IV studies. Arthroscopic distal clavicle excision results in more "good" or "excellent" outcomes compared with the open procedure. Both arthroscopic techniques result in success rates in excess of 90%, with the direct procedure permitting a quicker return to athletic activities. Performing distal clavicle excision in conjunction with either subacromial decompression or rotator cuff repair also has a high degree of success. A trend toward more "poor" results is seen when distal clavicle excision is performed in patients with post-traumatic acromioclavicular instability or in Workers' Compensation patients. CONCLUSIONS Our analysis suggests that among patients undergoing distal clavicle excision for acromioclavicular joint pathology, those having an arthroscopic procedure, specifically through the direct approach, can expect a faster return to activities while obtaining similar long-term outcomes compared with the open procedure. LEVEL OF EVIDENCE Level III, systematic review.

Analysis of the capsule and ligament insertions about the acromioclavicular joint: a cadaveric study. Arthroscopy 2009; 25:968-74.

Abstract
PURPOSE The purpose of this study was to analyze the capsular and ligamentous insertions about the acromioclavicular (AC) joint to determine the amount of bone that can be removed without destabilizing the joint. METHODS We dissected 28 cadaveric shoulders. The AC ligament insertions were measured under loupe magnification with a digital caliper on the acromial and clavicular sides on the anterior, posterior, superior, and inferior edges. We measured the distance to the coracoacromial (CA) and coracoclavicular ligaments. In addition, the axial and coronal angle of the AC joint was measured. RESULTS The AC joint capsular insertion on the acromion begins, on average, 2.8 mm (range, 2.3 to 3.3 mm) from the medial acromion and begins on the lateral clavicle a mean of 3.5 mm (range, 2.9 to 3.9 mm) from the distal clavicle. The mean capsular width ranged from 1.6 to 2.9 mm. The mean distance from the medial acromion to the CA ligament insertion was 3.5 mm. The mean axial angle of the AC joint was 51 degrees , with a 12 degrees coronal angle. The mean distance from the lateral clavicle to the start of the trapezoid ligament was 14.7 mm, and that to the conoid ligament was 32.1 mm. CONCLUSIONS An anatomic-based recommendation for safe AC joint resection is that 2 to 3 mm of the medial acromion and 3 to 4 mm of the distal clavicle can be resected without removing the AC capsular insertions. The trapezial and CA attachments are in close proximity to the AC capsular insertions. Medial resections greater that 15 mm will begin to take down the trapezoid ligament. Arthroscopic bone resection should be directed into the AC joint at approximately 50 degrees in the axial plane and 12 degrees in the coronal plane for safe symmetric resection. CLINICAL RELEVANCE These anatomic measurements suggest that AC joint resections (5 to 7 mm) with 2 to 3 mm from the acromial side and 3 to 4 mm from the clavicular side will not disrupt the stabilizing ligaments of the AC joint after distal clavicle resection.

Abstract
Arthroscopic resection of the distal clavicle has been advocated as a surgical treatment option for acromioclavicular (AC) joint pathology. To our knowledge, iatrogenic fracture of the distal clavicle during distal clavicle resection has never been reported. This report describes distal clavicle fracture as a complication of misidentification of the AC joint and subsequent aggressive burring of the distal clavicle during shoulder arthroscopy. This case is further complicated by the development of symptomatic delayed union and adhesive capsulitis. Ultimately, a revision distal clavicle resection was performed, underscoring the fact that special care must be taken to properly identify the AC joint and rule out pre-existing distal clavicle stress fracture or osteolysis before performing the arthroscopic Mumford procedure.

Arthroscopic versus open distal clavicle excision: comparative results at six months and one year from a randomized, prospective clinical trial. J Shoulder Elbow Surg 2007; 16:413-8.

Abstract
The purpose of this report is to compare outcomes after arthroscopic versus open distal clavicle excision in the treatment of refractory acromioclavicular joint pain. A randomized, prospective clinical trial comparing the 6-month and 1-year outcomes of patients undergoing open distal clavicle excision (group 1) with those undergoing arthroscopic distal clavicle excision (group 2) was carried out. The Modified American Shoulder and Elbow Surgeons form, visual analog scale pain score, Short Form 36, and satisfaction questions were assessed preoperatively and at 6 months and 1 year postoperatively. Seventeen patients were enrolled. There was a trend across all measures for earlier or better outcomes (or both) after arthroscopic over open treatment. The improvement in visual analog scale pain score from preoperatively to 1 year postoperatively was significant for group 2 but not group 1 (P = .006 vs P = .13). Occult intra-articular pathology was detected and treated in 50% of group 2 patients. Arthroscopic and open distal clavicle excisions both provide significant pain reduction at 1 year. Both are effective surgeries for the treatment of refractory acromioclavicular joint pain. The ability to diagnosis and treat subtle concomitant shoulder pathology is a unique advantage of the arthroscopic approach.

Abstract
PURPOSE The superior-medial (SM) shoulder arthroscopic portal (Neviaser portal) is the portal anatomically closest to the suprascapular nerve, and any potential benefits of this portal would be mitigated if risk of suprascapular nerve injury were significant. The purpose of this study is to determine the safety of the SM arthroscopic shoulder portal. We hypothesize that the SM shoulder arthroscopic portal is safe. METHODS Twelve fresh cadaveric shoulders were securely positioned to simulate shoulder arthroscopy in the beach-chair position with the arm at the patient's side in neutral rotation. An SM portal was established 1 cm medial to the acromion and 1 cm posterior to the clavicle, and a 5.5-mm burr sheath was oriented toward the acromioclavicular joint. The skin and trapezius were resected, the supraspinatus was retracted, and the suprascapular nerve was identified. The distance between the sheath and the nerve was measured by 2 independent observers with calipers. A safe distance was defined as 10 mm. RESULTS The measured distances between the nerve and burr ranged from 18.5 to 35.7 mm, with a mean of 24.2 +/- 5 mm. The distance is significantly greater than the safe distance of 10 mm (P < .0001). CONCLUSIONS This study shows that the SM portal is safe. The distance between an instrument oriented toward the acromioclavicular joint via the SM portal and the suprascapular nerve was 18.5 mm or greater in all specimens. CLINICAL RELEVANCE Our study has clinical relevance because the SM portal is useful for arthroscopic rotator cuff repair, arthroscopic superior labrum repair, and arthroscopic distal clavicle excision.

Abstract
Excision of the distal clavicle has become the mainstay of surgical treatment for acromioclavicular joint arthritis and osteolysis refractory to nonoperative management. Surgical options for symptomatic acromioclavicular joint abnormalities refractory to nonoperative treatment are the classic open distal clavicle excision, direct (superior) arthroscopic excision, and indirect (bursal) arthroscopic distal clavicle excision. We asked whether any of these three procedures provided a better result. We systematically reviewed the medical literature (Medline, EMBASE), assigned a level of evidence for available studies, and critically identified the flaws and biases in the studies to provide comparisons between the published reports. We limited the literature review to clinical reports in the English language published in peer-reviewed journals. The literature supports surgical excision, but the reports are all Level III or IV evidence consisting largely of retrospective case series. Arthroscopic distal clavicle resection has provided more "good or excellent" results than has the open procedure, but is comprised of low-level evidence. Distal clavicle resection has provided satisfactory results when combined with other procedures. Simple distal clavicle resection may have worse outcomes when performed after preceding trauma. The published reports of the removal of medial acromial and inferior distal clavicle osteophytes when performing subacromial decompression are conflicting and may increase post-operative acromioclavicular symptoms.

Abstract
Acromioclavicular joint injuries and, more specifically, separations are commonplace both in general practice and during athletic participation. This article reviews the traditional classification as well as the clinical evaluation of patients with acute and chronic acromioclavicular joint separations. It also highlights many recent advances, principally in the anatomy and biomechanics of the acromioclavicular joint ligamentous complex. The concept of increases in superior translation as well as disturbances in horizontal translation with injuries to this joint and ligaments are discussed. This information, coupled with the unpredictable long-term results with the Weaver-Dunn procedure and its modifications, have prompted many recent biomechanical studies evaluating potential improvements in the surgical management of acute and chronic injuries. The authors present these recent works investigating cyclic loading and ultimate failure of traditional reconstructions, augmentations, use of free graft, and the more recent anatomic reconstruction of the conoid and trapezoid ligaments. The clinical results (largely retrospective), including acromioclavicular joint repair, reconstruction and augmentation with the coracoclavicular ligament, supplemental sutures, and the use of free autogenous grafts, are summarized. Finally, complications and the concept of the failed distal clavicle resection and reconstruction are addressed. The intent is to provide a current, in-depth treatise on all aspects of acromioclavicular joint complex injuries to include anatomy, biomechanics, benchmark studies on instability and reconstruction, clinical and radiographic evaluation, and to present the most recent clinical research on surgical outcomes.

Abstract
Although nonoperative treatment is considered the standard of care for the treatment of Grade I and II acromioclavicular (AC) joint injuries, the treatment of Grade III injuries is controversial. There are as many methods of nonoperative treatment as there are for operative stabilization. Most of the literature represents Level IV evidence with very few Level II and III studies upon which to base decisions. A systematic review of the English-language literature was performed to determine if Grade III AC joint separations are best treated operatively or nonoperatively. Based on limited low-evidence, nonoperative treatment was deemed more appropriate than traditional nonoperative treatments because the results of the latter were not clearly better and were associated with higher complication rates, longer convalescence, and longer time away from work and sport.

Abstract
BACKGROUND The clinical success of arthroscopic distal clavicle resection for athletes has been well documented. There are, however, no published studies that prospectively compare the recovery rates in athletes as well as the outcomes of the indirect versus direct approaches. HYPOTHESIS Both procedures are equally successful; however, the direct approach affords faster return to sports. STUDY DESIGN Randomized controlled clinical trial; Level of evidence, 2. METHODS Thirty-eight consecutive athletes with osteolysis of the distal clavicle or isolated posttraumatic arthrosis of the acromioclavicular joint without instability underwent arthroscopic distal clavicle resection. The patients were randomized into 2 groups: a direct superior approach and an indirect subacromial approach. American Shoulder and Elbow Surgeons and Athletic Shoulder Scoring System scores were measurable outcomes. RESULTS Thirty-four athletes were available for a minimum 2-year follow-up. The 2 groups were similar, including preoperative American Shoulder and Elbow Surgeons and Athletic Shoulder Scoring System scores. Both groups demonstrated significant improvement in both scores at final follow-up when compared with preoperative scores (P < .001). The direct group demonstrated higher American Shoulder and Elbow Surgeons (82 vs 64) and Athletic Shoulder Scoring System (74 vs 56) scores at week 2 (P < .001) and week 6 (American Shoulder and Elbow Surgeons, 88 vs 77; Athletic Shoulder Scoring System, 87 vs 73) (P < .001). At final follow-up, both groups demonstrated excellent clinical outcomes, even though there was a statistical difference in scores, with the direct group scoring better (American Shoulder and Elbow Surgeons, 95.7 vs 91.2; Athletic Shoulder Scoring System -94.9 vs 88.3). The direct group demonstrated faster return to sports (mean, 21 days) than the indirect group (mean, 42 days) (P < .001). Radiographic analysis demonstrated an equivalent resection. One patient in each group had a clinically insignificant increase in coracoclavicular distance. CONCLUSIONS Both the direct superior approach and the indirect subacromial approach to the arthroscopic distal clavicle resection result in successful clinical outcome with clinically insignificant difference at final follow-up. Athletes treated with the direct superior approach improved faster clinically and returned to sports earlier.

Abstract
PURPOSE To test the hypothesis that the direct (superior) approach to arthroscopic distal clavicle resection is as safe and effective as the bursal (subacromial) approach. METHODS All patients who had an arthroscopic distal clavicle resection in our institution between 1994 and 2002 were reviewed. Patients with a history of acromioclavicular joint (ACJ) instability, previous shoulder surgery, glenohumeral pathology, full-thickness rotator cuff tear, or other significant orthopaedic comorbidity were excluded. Outcome data were collected including the American Shoulder and Elbow Surgeons (ASES) score as well as subjective ratings of pain and instability. RESULTS Follow-up was completed on 66 shoulders of 60 patients. Twenty-four shoulders had a bursal approach (group I) and 42 had a direct approach (group II). There were 45 men and 15 women with an average age of 46 years (range, 21 to 78 years). Follow-up averaged 6.0 years (range, 2 to 11.5 years). The average ASES score was 90 (range, 53-100) in group I and 94 (range, 55-100) in group II. Four patients (10%) in group II required reoperation: 2 patients required ACJ stabilization at 6 and 9 months postoperatively because of anteroposterior instability, and 2 patients required resection again at 5 years because of recurrent symptoms. CONCLUSIONS Both the direct and bursal approaches lead to satisfactory outcomes in the majority of patients with ACJ arthrosis. However, the direct approach to the ACJ may damage the superior capsular ligaments, potentially leading to distal clavicle instability. Care should be taken when performing the direct ACJ resection to avoid disrupting the capsular restraints. LEVEL OF EVIDENCE Level IV therapeutic case series.

Abstract
The purpose of this study was to compare acromioclavicular (AC) joint magnetic resonance imaging (MRI) findings in asymptomatic patients with those in symptomatic patients. The MRI scans of 25 patients with symptomatic AC joints were compared with 50 asymptomatic control subjects by use of the same grading scale. In the symptomatic group, AC joint arthritis grading was normal in 0%, mild in 20%, moderate in 52%, and severe in 28%. In the asymptomatic group, grading was normal in 18%, mild in 66%, moderate in 12%, and severe in 4%; there was a statistically higher grade of AC arthritis in the symptomatic group (P < .05). Of the symptomatic individuals, 80% demonstrated reactive bone edema in either the distal clavicle (6), the acromion (3), or both sides of the AC joint (11), whereas no individual in the asymptomatic group had this finding (P < .05). Reactive bone edema on MRI is a more reliable predictor of symptomatic AC pathology than degenerative changes seen on MRI and, when correlated with clinical examination, is reproducible.

Abstract
PURPOSE To compare the horizontal stability of the distal clavicle following arthroscopic resection of its lateral end by direct and indirect techniques. TYPE OF STUDY Biomechanical test of cadaveric specimens. METHODS We performed arthroscopic distal clavicle resection on 12 fresh-frozen human cadaveric shoulders using direct (group 1, n = 6) or indirect (group 2, n = 6) approaches. In both groups 5 mm of distal clavicle were resected using an arthroscopic burr. The specimens were mounted on a materials testing device that allowed translation of the clavicle along the anteroposterior axis. The degree of posterior translation was measured from maximum anterior displacement of the clavicle. RESULTS Mean posterior translation was 19.4 mm (range, 18 to 23 mm; SD, 2.2) and 21.3 mm (range, 18 to 25 mm; SD, 3.1) for groups 1 and 2, respectively. This difference was not statistically significant ( P = .27). CONCLUSIONS This study suggests that there is no significant difference in anteroposterior stability of the clavicle following arthroscopic distal clavicle resection with either a direct or indirect approach. CLINICAL RELEVANCE Clinically, this study addresses concerns about increased potential instability associated with the indirect technique of distal clavicle resection. From a biomechanical standpoint, based on this study, there is no concern for increased instability with the indirect technique of distal clavicle resection compared to a direct technique.

Abstract
BACKGROUND The potential destabilizing effect of distal clavicle resection has received limited attention. HYPOTHESIS Suturing the coracoacromial ligament to the undersurface of the distal clavicle after resection could counter clavicle instability. STUDY DESIGN Controlled laboratory study. METHODS The effect of ligament augmentation on posterior translation of the clavicle after resection was evaluated using 12 fresh-frozen cadaveric shoulders. Posterior clavicular displacement was measured after the application of a 70-N load under 4 different conditions: (1) the intact joint, (2) after distal clavicle resection, (3) clavicle resection plus acromioclavicular capsular ligament repair, and (4) clavicle resection plus acromioclavicular capsular ligament repair plus coracoacromial ligament augmentation. RESULTS Mean displacements for each of the test conditions were as follows: (1) 5.60 mm, (2) 7.38 mm, (3) 7.54 mm, and (4) 6.34 mm. A 32% increase in posterior translation was measured after resection compared to the intact specimen. No reduction in posterior displacement was noted after capsular repair; however, displacement decreased significantly when capsular repair was coupled with ligament augmentation. CONCLUSIONS Results suggest that the destabilizing effect of clavicle resection can be partially countered by the proposed ligament augmentation. CLINICAL RELEVANCE That the destabilizing effect of clavicle resection can be partially countered by the proposed ligament augmentation may be particularly relevant in cases of resection for posttraumatic arthritis after acromioclavicular separation in which some degree of preexisting acromioclavicular capsular attenuation and consequently acromioclavicular joint laxity may be presumed.

Abstract
Remaining superior osteophytes or osseous spurs after arthroscopic lateral clavicle resection can cause persistent pain and could lead to revision surgery. A new method of intraoperative ultrasonographic imaging of the result of the operation during arthroscopic lateral clavicle resection is presented. In 10 patients with acromioclavicular arthritis, standardized arthroscopic lateral clavicle resection was performed. Intraoperatively, the space between the clavicle and the acromion was measured before and after arthroscopic acromioclavicular resection using a Sonosite 180 plus (SonoSite, Bothell, WA) with a 10-MHz broadband linear array in a sterile bag. The width of the joint space between the clavicle and the acromion was between 0.38 and 0.56 cm before operation and 0.92 cm and 1.28 cm after operation (nine cases). In one case, the anticipated minimum resection of 0.5 cm was not achieved at the sonographic measurement and further resection was required. Real-time ultrasonography allows exact measurement of the amount of resected bone during arthroscopic lateral clavicle resection. This could avoid revision surgery resulting from persisting disability caused by insufficient or extensive bone resection.

Abstract
BACKGROUND This prospective study was performed to determine which clinical and imaging tests were most helpful for diagnosing acromioclavicular joint pain. METHODS Of 1037 patients with shoulder pain, 113 who mapped pain within an area bounded by the midpart of the clavicle and the deltoid insertion were eligible for inclusion in the study. Forty-two subjects agreed to participate, and four of them were lost to follow-up. Twenty clinical tests, radiography, bone-scanning, magnetic resonance imaging, and an acromioclavicular joint injection test were performed on all patients. The patients were divided into two groups according to whether they had a > or =50% decrease in pain following the acromioclavicular joint injection. Statistical analysis, including multivariate regression analysis, was performed in order to evaluate the diagnostic effectiveness of the various tests. RESULTS Acromioclavicular joint pain was confirmed in twenty-eight of the thirty-eight patients. The most sensitive tests were examination for acromioclavicular tenderness (96% sensitivity), the Paxinos test (79%), magnetic resonance imaging (85%), and bone-scanning (82%), but these studies had low specificity. In the stepwise regression model, with the response to the injection used as the dependent variable, bone-scanning and the Paxinos test were the only independent variables retained. Patients with a positive Paxinos test as well as a positive bone scan had high post-test odds (55:1) and a 99% post-test probability of having pain due to pathological changes in the acromioclavicular joint. The likelihood ratio for patients with one negative test and one positive test was indeterminate (0.4:1). Patients with both a negative Paxinos test and a negative bone scan had a likelihood ratio of 0.03:1 for having acromioclavicular joint pain, which basically rules out the disorder. CONCLUSIONS The highly sensitive tests had low specificity, and the highly specific tests had low sensitivity. However, the combination of a positive Paxinos test and a positive bone scan predicted damage to the acromioclavicular joint as the cause of shoulder pain with a high degree of confidence.

Abstract
The purpose of this study was to assess the results of acute grade I and II acromioclavicular (AC) joint sprains treated by conservative measures. Between 1993 and 1997, 37 consecutive patients were treated conservatively for AC joint sprains, grade I and II in the Tossy classification. Of these patients, 4 were excluded (three lost to follow-up and one sustained a further AC injury), leaving a series of 33 patients. Among them, in 9 (27%), chronic AC joint pathology that required subsequent surgery developed at a mean of 26 months after injury. The remaining 24 were reviewed clinically and radiologically at a mean of 6.3 years (range, 4-8 years) after injury. At the latest follow-up, 17 of the 33 patients (52%) remained asymptomatic. Of the 24 patients reviewed, 7 complained of activity-related pain. Eight patients presented with residual anteroposterior instability. Tenderness at the AC joint as well as a positive cross-body test was observed in 12 patients. The mean Constant score at follow-up was 82 points. The x-ray films showed degenerative changes in 13 patients, ossification of the coracoclavicular ligaments in 2, an association of degenerative changes with ossification of the coracoclavicular ligaments in 3, and distal clavicular osteolysis in 3. Only 4 cases had no radiographic changes after this kind of AC injury. On the basis of these results, we conclude that the severity of the consequences after grade I and II AC sprains is underestimated.

Abstract
Resection is the accepted treatment for arthritis of the acromioclavicular joint. It may be performed either open or arthroscopically. During arthroscopic resection, visualizing the superior aspect of the joint and determining the limit of resection can be difficult. We describe a new technique to improve visualization during the procedure.

Abstract
OBJECTIVE Our objective was to evaluate the predictive value of various MRI findings in the acromioclavicular joint for pain relief after intraarticular injection. MATERIALS AND METHODS The acromioclavicular joint of 50 patients (20 women, 30 men; mean age, 51 years; range, 25-75 years) was evaluated on MRIs of the shoulder. Osteophytes, subchondral cysts and irregularities, bone marrow edema, joint effusion, and joint capsule hypertrophy were assessed by two musculoskeletal radiologists in consensus. Local anesthetics were injected into the acromioclavicular joint with fluoroscopic guidance. Patients graded pain relief on a visual analogue scale (0-100%) after 15 min. The relationship between pain relief and MRI findings was assessed with the Mann-Whitney U test. Pain relief equal to or greater than 70% was rated as a positive response to the injection. This cutoff value was used to calculate sensitivity, specificity, accuracy, and predictive values of the various MRI findings in determining which acromioclavicular joints were responsive to joint injections. RESULTS Mean pain relief after injection was 38%. Pain relief was significantly related to capsular hypertrophy (p = 0.007) and was equal to or greater than 70% in 11 patients. The sensitivity in diagnosing a successful injection (range, 9-82%) was highest for caudal osteophytes (82%) and capsular hypertrophy (73%). The specificity (range, 51-97%) was highest for subchondral cysts (97%), subchondral bone marrow edema (95%), and joint effusion (92%). CONCLUSION Pain relief after intraarticular injection is significantly related to capsular hypertrophy diagnosed on MRI. MRI findings have a reasonable sensitivity and a high specificity in predicting relevant short-term pain relief after intraarticular injection.

Abstract
We describe the insertional variations of supporting ligaments of the acromioclavicular joint, especially with respect to gender. We analyzed 41 cadaveric clavicles (22 female and 19 male) with attached ligaments. The distance between the insertion of the trapezoid ligament and the distal end of the clavicle was not significantly different between sexes, although that of the conoid ligament and the mean anteroposterior width of the distal clavicle was significantly greater in men. Although there are significant sex-related differences in the insertional distances of the CC ligaments, resection of less than 11.0 mm should not violate the trapezoid ligament and less than 24.0 mm should not violate the conoid ligament in either sex in 98% of the general population. Resection of more than 7.6 mm of the distal clavicle in men and 5.2 mm in women, performed by an arthroscopic approach, may violate the superior acromioclavicular ligament.

Abstract
Injuries and conditions that affect the AC joint are common. Low-grade separations, degenerative conditions, and osteolysis of the distal clavicle are frequently dealt with by the treating physician. Proper assessment requires a thorough history, examination, and radiologic work-up. An injection of bupivicaine into the AC joint can be a very useful test to evaluate the source of pain about the symptomatic shoulder. Most conditions affecting the AC joint can be treated conservatively, but patients who do not respond to these treatments or athletes who do not wish to modify their activities may require resection of the distal clavicle and the AC joint. Operative intervention can be performed as an open procedure with good results. Recent advances in operative arthroscopic procedures allow us to replicate and exceed the results of the open resection. Arthroscopic resection can be undertaken via a direct approach that does not violate the subacromial space or via an indirect or bursal approach. The indirect approach allows you to assess both the subacromial space and the AC joint because impingement pathology and subacromial compromise are frequently associated with AC change. The advantage of an arthroscopic resection is its ability to be performed as an outpatient procedure with less compromise of musculotendinous structures, shorter rehabilitation, and quicker return to activity. The amount of bone resection necessary is less than with the open procedure because of the ability to preserve the stabilizing properties of the superior AC ligaments. Resection of 4 mm to 8 mm of bone is all that may be required to give uniformly good results. Arthroscopic resection of the distal clavicle is technically demanding and requires skill and familiarity with other arthroscopic shoulder procedures. Complications related to this procedure are relatively infrequent and include infection, residual pain, lack of adequate bone resection, and instability, particularly in patients with previous grade 1 and 2 separations. Less commonly noted is the symptomatic development of heterotopic bone. To the accomplished arthroscopic shoulder surgeon, arthroscopic resection of the symptomatic AC joint gives excellent clinical results that allow a compromised athlete a relatively quick return to desired sport activities.

Abstract
Sonography is commonly used for the evaluation of shoulder symptoms. This report describes some of the bony and/or calcific changes that may be visualized in the ultrasound examination of the shoulder and may not have been detected by other modalities. Sonography is able to accurately predict the diameter of the acromioclavicular joint as well as determine the presence or absence of osteoarthritis at this joint. The os acromiale is amenable to ultrasonic detection also. Sonography appears to be more sensitive in the detection of rotator cuff calcification than the standard shoulder x-ray series and has the additional advantage of precise localization of the tendon of origin of the calcification. Sonography is able to reliably detect fractures around the greater tuberosity, and the Hill-Sachs lesion may also be seen. Changes of irregularity, cyst formation, and sclerosis around the greater tuberosity may occur in association with the impingement syndrome. These changes lead to irregularity of the greater tuberosity. Sonography can detect these changes and, to some degree, grade their severity.

Abstract
The purpose of this study was to determine the prevalence of acromioclavicular joint (ACJ) arthritis with magnetic resonance imaging (MRI) evaluation in asymptomatic patients. Fifty shoulders in 42 patients were evaluated with the use of standard MRI techniques. There were 18 men and 24 women with an average age of 35 years (range, 19 to 72). ACJ arthritic changes were graded on a scale from 1 to 4 (none, mild, moderate, and severe), based on the amount of subacromial fat effacement, joint space narrowing, irregularity, capsular distension, and osteophyte formation. Forty-one (82%) of 50 shoulders had abnormalities consistent with arthritis on MRI. Patients were divided into two groups according to age: those older than 30 years and those 30 years old or younger. In the 30-and-under age group, 68% of the shoulders had arthritic changes, whereas in the over-30 age group, 93% had arthritic changes. Furthermore, in a comparison of the two groups, more advanced arthritic changes were found in the over-30 age group (P <.05). Clinical decisions to resect the ACJ should correlate the physical examination with the MRI findings because many patients may be clinically asymptomatic.

Abstract
BACKGROUND Arthroscopic subacromial decompression and arthroscopic resection of the acromioclavicular joint as separate procedures have been well documented. However, there is little information on the success rate of resection with concomitant decompression. In this study, we retrospectively evaluated the results of a consecutive group of patients who underwent arthroscopic resection of the acromioclavicular joint with concomitant subacromial decompression. METHODS We evaluated the surgical results in thirty-one consecutive patients (thirty-two shoulders) with acromioclavicular pathology with concomitant subacromial impingement. The mean age of the patients at the time of surgery was thirty-six years (range, eighteen to sixty-seven years). Twenty-five patients, including four professional athletes, were actively involved in sports activities. The mean duration of follow-up was four years and ten months (range, three to eight years). The follow-up examination included clinical evaluation, chart review, radiographic analysis, and isokinetic testing of both upper extremities. RESULTS Of the twenty-five patients who participated in sports, twenty-two (including the four professional athletes) returned to their previous level of sports activity. Twenty-six patients had no pain, three reported mild pain on strenuous repetitive overhead activity, two (both weight-lifters) had occasional pain in the acromioclavicular joint and the lateral aspect of the shoulder with bench-pressing, and two (both baseball players) had mild pain in the posterior aspect of the shoulder with throwing. All of the patients were satisfied with the results. In the absence of a complete rotator cuff tear, isokinetic strength-testing of both upper extremities failed to demonstrate any weakness of the involved shoulder. The mean functional score for individual activities was 2.7 points (range, 2.1 to 3.0 points) preoperatively and 3.9 points (range, 3.6 to 4.0 points) postoperatively (p = 0.0001). No patient had superior migration of the clavicle. The amount of distal clavicular resection averaged 9 mm (range, 7 to 15 mm). One patient had heterotopic ossification at the resection site, with mild pain on direct palpation of the acromioclavicular joint and on strenuous overhead activity. Five patients had calcification at the anterior deltoid insertion into the acromion that was asymptomatic, with no impingement on overhead activity and no pain on direct palpation. CONCLUSIONS We found excellent results with arthroscopic resection of the acromioclavicular joint and concomitant subacromial decompression. When this procedure is performed on properly selected patients, the results are similar to those of an open approach.

Abstract
PURPOSE The purpose of this study was to evaluate the outcome of arthroscopic distal clavicle resection by the direct superior approach for treatment of isolated osteolysis of the distal clavicle. TYPE OF STUDY Case series. MATERIALS AND METHODS Forty-one shoulders in 37 patients underwent arthroscopic resection of the distal clavicle. Thirty-three patients were male and 4 female, with an average age of 39 years. All patients complained of pain localized to the acromioclavicular joint region. Symptoms began after a traumatic event in 18 shoulders and were associated with repetitive stressful activity in 23 shoulders. RESULTS At an average follow-up of 6.2 years, 22 shoulders had excellent results, 16 had good results, and 3 were failures. All 3 failures occurred in patients with a traumatic etiology. CONCLUSIONS Arthroscopic resection for osteolysis of the distal clavicle has results comparable to open excision with low morbidity. Patients with a traumatic etiology had slightly worse results compared with patients with a microtraumatic etiology.

Abstract
Twenty-five patients underwent arthroscopic debridement to treat early glenohumeral osteoarthritis. The group consisted of 19 men and 6 women with an average age of 46 years (range, 27 to 72 years.) The operative procedure consisted of lavage of the glenohumeral joint, debridement of labral tears and chondral lesions, loose body removal, and partial synovectomy and subacromial bursectomy. Follow-up averaged 34 months, with a range of 12 to 63 months. Overall, results were rated as excellent in 2 patients (8%), good in 19 patients (72%), and unsatisfactory in 5 (20%). Two patients had complete relief of pain, 18 patients had only occasional mild pain, and 5 had moderate to severe pain postoperatively. Of the 12 patients with marked preoperative stiffness, 10 (83%) had improvement in range of motion postoperatively. Arthroscopic debridement is a reasonable approach for treating early glenohumeral osteoarthritis that has failed to respond to nonoperative treatment, in which the humeral head and glenoid remain concentric, and where there is still a visible joint space on an axillary radiograph. The procedure is not recommended when there is severe joint incongruity or large osteophytes.
