RESUMEN
Nineteen patients presented with an unsightly deformity of the shoulder, pain or discomfort at the medial scapular border, pseudo nonparalytic scapular winging, and thoracic outlet symptoms after excessive resection of the clavicle for either complete acromioclavicular separation or displaced fracture of the outer clavicle, which allows the scapula and shoulder to rotate anteriorly and inferiorly on the chest creating traction on the medial scapular muscles and the brachial plexus resulting in pseudo nonparalytic winging and thoracic outlet symptoms. RESULTS: All underwent transfer of the coracoid process with the attached conjoined tendon to the end of the clavicle, restoring length and alignment. Eighteen patients were evaluated at a mean of 13.3 years. Seventeen had resolution of symptoms, restored alignment of the clavicle with the shoulder, improved appearance, healed transfer, and were pleased with the outcome. One patient was lost to follow-up but was considered a failure at his last visit. In a second patient, the transfer healed in a tilted position and the patient was dissatisfied with the appearance but otherwise had resolution of his symptoms. The mean American Shoulder and Elbow Surgeons Outcome Score improved from 53.2 preoperatively to 87.4 postoperatively (P < .02). CONCLUSION: This is the first report of using this transfer to restore length and alignment of an excessively short, unstable clavicle. The transfer succeeded in improving the appearance and symptoms in this complication of an excessively short, unstable clavicle.

Medicare cost-containment efforts have uniformly led to a reduction in physician reimbursement offset by increasing administrative burdens and costs and complicating delivery of care. Surgeons who face decreasing compensation for Medicare patients may be forced to limit the number of these patients for whom they care. Decreasing physician reimbursement from Medicare typically translates into a similar reduction by private payers. Administrators who come at a cost have yet to show proven value. All of this translates into limiting our ability to care for patients. We are facing a critical moment for potential change prompted by a global health crisis, a new administration, a new legislature, and an increased appreciation for health care delivery among the American public. As physicians, we need to be active participants in changing the system, placing a greater priority on delivering optimal care at optimal cost. We should use this moment when the American public is focused on the need for health care to reprioritize Medicare funding and physician reimbursement while urging reductions of government spending on bureaucracy. This requires actively lobbying lawmakers and speaking collectively.

PURPOSE: To utilize a national all-payer claims dataset to understand whether a history of a prior shoulder arthroscopy is associated with adverse outcomes or complications after the index shoulder arthroplasty itself. METHODS: The Symphony Integrated DataVerse, an all-payer claims database, was used to identify patients undergoing primary shoulder arthroplasty (hemiarthroplasty, anatomic total shoulder arthroplasty, or reverse total shoulder arthroplasty) between 2017 to 2018. Current Procedural Terminology codes were used to identify patients who had undergone a shoulder arthroscopic procedure on the ipsilateral side within 2 years before the arthroplasty. Multivariate logistic regression analyses were used to assess whether prior shoulder arthroscopy was associated with higher risks of wound complications, postoperative stiffness, mechanical complications, prosthetic joint infection, revision surgery and readmissions within 90 days of the arthroplasty. RESULTS: In total, 19,429 patients were included, of which 837 (4.3%) had undergone shoulder arthroscopy within 2 years before the arthroplasty. Prior shoulder arthroscopy was associated with a significantly higher risk of prosthetic joint infection (odds ratio [OR] 2.74 [95% confidence interval {CI} 1.51-4.69]; P < .001) within 90 days of the arthroplasty. The greatest risk of prosthetic joint infection was associated with arthroscopies that took place within 3 months before the arthroplasty (OR 5.32 [95% CI 1.42-15.14]; P = .005). CONCLUSIONS: Undergoing an arthroscopic procedure of the ipsilateral shoulder before undergoing an arthroplasty was associated with greater risk of prosthetic joint infection. Furthermore, it appears that patients who received arthroscopy within the 3 months before arthroplasty had the highest risk of prosthetic joint infections. Physicians should not only anticipate possible inferior outcomes in patients who have had prior arthroscopy, but also consider delaying the arthroplasty by at least 3 months after the arthroscopy to mitigate the risks of experiencing this costly adverse event. LEVEL OF EVIDENCE: III.

PURPOSE: To identify intraoperative drivers of cost associated with arthroscopic rotator cuff repairs (RCRs) through analysis of an institutional database. METHODS: This was a single-institution retrospective review of arthroscopic RCRs performed at an ambulatory surgical center between November 2016 and July 2019. Patient-level factors analyzed included age, sex, insurance type (private, Medicare, Medicaid, self-pay, and other government), American Society of Anesthesiologists grade (I, II, III, and missing), and Charlson comorbidity index (0, 1, 2, and ≥3). Procedure-level factors included use of biologics (decellularized dermal allograft or bioinductive healing implant), anesthesia type (regional block, monitored anesthesia care, or general), number of anchors and sutures, additional procedures (biceps tenodesis, distal clavicle resection, subacromial decompression), and operative time. Multivariate linear regression analysis was used to identify factors significantly associated with higher or lower charges. RESULTS: A total of 712 arthroscopic RCRs were included. The risk-adjusted operative charges were $19,728 (95% confidence interval $16,543 to $22,913). The above factors predicted nearly 65% of the variability in operative charges. The only patient-level factor significantly associated with lower charges was female sex (- $1,339; P = .002). Procedure-level factors significantly associated with higher charges were use of biologics (+ $17,791; P < .001), concurrent open biceps tenodesis (+ $4,027; P < .001), distal clavicle resection (+ $2,266; P = .039), use of regional block (+ $1,256; P = .004), number of anchors (+ $2,245/anchor; P < .001), and increasing operative time ($26/min). Other factors had no significant association. CONCLUSIONS: Procedural factors are the most significant drivers of operative cost in arthroscopic RCRs, such as quantity and type of implants; additional procedures such as biceps tenodesis and distal clavicle resection; and perioperative conditions such as type of anesthesia and total operating room time. Overall, patient-level factors were not shown to correlate well with operative costs, other than lower charges with female sex. LEVEL OF EVIDENCE: IV, economic study.

PURPOSE: To identify factors predictive of a large labral tear at the time of shoulder instability surgery. METHODS: As part of the Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Instability cohort, patients undergoing open or arthroscopic shoulder instability surgery for a labral tear were evaluated. Patients with >270° tears were defined as having large labral tears. To build a predictive logistic regression model for large tears, the Feasible Solutions Algorithm was used to add significant interaction effects. RESULTS: After applying exclusion criteria, 1235 patients were available for analysis. There were 222 females (18.0%) and 1013 males (82.0%) in the cohort, with an average age of 24.7 years (range 12 to 66). The prevalence of large tears was 4.6% (n = 57), with the average tear size being 141.9°. Males accounted for significantly more of the large tears seen in the cohort (94.7%, P = .01). Racquet sports (P = .01), swimming (P = .02), softball (P = .05), skiing (P = .04), and golf (P = .04) were all associated with large labral tears, as was a higher Western Ontario Shoulder Instability Index (WOSI; P = .01). Age, race, history of dislocation, and injury during sport were not associated with having a larger tear. Using our predictive logistic regression model for large tears, patients with a larger body mass index (BMI) who played contact sports were also more likely to have large tears (P = .007). CONCLUSIONS: Multiple factors were identified as being associated with large labral tears at the time of surgery, including male sex, preoperative WOSI score, and participation in certain sports including racquet sports, softball, skiing, swimming, and golf. LEVEL OF EVIDENCE: I, prognostic study.

INTRODUCTION: The rate of venous thromboembolism following surgical treatment of proximal humerus fractures is not well established. METHODS: A retrospective review of all patients undergoing surgical treatment for proximal humerus fractures from September 2011 to May 2017 was performed. Included patients received only mechanoprophylaxis using sequential compression devises. All patients had at least 6 months follow-up. The primary outcome of interest was the rate of postoperative DVT and PE. RESULTS: 131 patients underwent 139 surgeries for proximal humerus fracture. After exclusion criteria were applied, 92 patients who underwent 92 surgeries were included. There were 47 females and 45 males. Five (5.4%) were taking Aspirin 81 mg preoperatively. There were 76 cases of open reduction and internal fixation (ORIF), 8 cases of reverse total shoulder arthroplasty, 4 cases of hemiarthroplasty, 3 cases of closed reduction percutaneous pinning (CRPP), 1 case of open reduction without fixation. 53.3% of patients had one or more risk factors for VTE. There were no cases of fatal PE or DVT. There were two cases of symptomatic PE (2.2%) following one ORIF and one CRPP. There was one additional case of asymptomatic PE found incidentally after ORIF. Overall VTE rate was 3.3%. Fisher's exact test yielded that there was no significant association between the presence of VTE risk factors and prevalence of VTE postoperatively (p = 0.245). CONCLUSIONS: The incidence of symptomatic VTE after surgery for proximal humerus fractures is low. Chemical VTE prophylaxis in patients after surgical fixation for proximal humerus fractures is not universally indicated. Selective prophylaxis for patients with systemic risk factors may be warranted.

BACKGROUND: Both anatomic and reverse total shoulder arthroplasty are considered successful surgeries to treat a variety of painful shoulder conditions. Although implant survivorship for both is good to excellent in the long term, a variety of factors-clinical, technical, and psychosocial-may affect patient-reported outcomes after shoulder arthroplasty. METHODS: A comprehensive review of the literature was performed systematically using keywords "shoulder arthroplasty outcomes," "psychosocial factors shoulder," "shoulder replacement outcomes," "depression shoulder arthroplasty," "satisfaction shoulder arthroplasty," "factors shoulder replacement," "expectations shoulder arthroplasty," and "predictors shoulder arthroplasty." Studies meeting the inclusion criteria were screened and analyzed. Type of surgery performed, sample size, outcome measures, and other factors influencing patient outcomes were recorded and analyzed. RESULTS: Sixteen studies met the inclusion criteria. Six reviewed mental health disorders as predictors of postoperative outcome after shoulder arthroplasty. Of these, 4 found that disorders such a depression and anxiety were associated with increased risk of perioperative complications and lower final functional outcome scores. Two studies evaluated workers' compensation status as a possible predictor of outcomes and found that patients with claims had lower satisfaction and outcome scores at final follow-up compared with those without claims. Two studies showed that preoperative opioid use was associated with lower outcome scores and overall satisfaction rate after shoulder arthroplasty. Three studies showed that higher patient confidence and preoperative expectations were correlated with better outcomes. CONCLUSION: Our review shows that psychosocial factors may play just as important role in affecting patient outcomes after total shoulder arthroplasty as technical factors.

BACKGROUND: The current Centers for Medicare & Medicaid Services diagnosis-related group (DRG) bundled-payment model for upper-extremity arthroplasty does not differentiate between the type of arthroplasty (anatomic total shoulder arthroplasty [ATSA] vs. reverse total shoulder arthroplasty vs. total elbow arthroplasty [TEA] vs. total wrist arthroplasty) or the diagnosis and indication for surgery (fracture vs. degenerative osteoarthritis vs. inflammatory arthritis). METHODS: The 2011-2014 Medicare 5% Standard Analytical Files (SAF5) database was queried to identify patients undergoing upper-extremity arthroplasty under DRG-483 and -484. Multivariate linear regression modeling was used to assess the marginal cost impact of patient-, procedure-, diagnosis-, and state-level factors on 90-day reimbursements. RESULTS: Of 6101 patients undergoing upper-extremity arthroplasty, 3851 (63.1%) fell under DRG-484 and 2250 (36.9%) were classified under DRG-483. The 90-day risk-adjusted cost of an ATSA for degenerative osteoarthritis was $14,704 ± $655. Patient-level factors associated with higher 90-day reimbursements were male sex (+$777), age 75-79 years (+$740), age 80-84 years (+$1140), and age 85 years or older (+$984). Undergoing a TEA (+$2175) was associated with higher reimbursements, whereas undergoing a shoulder hemiarthroplasty (-$1000) was associated with lower reimbursements. Surgery for a fracture (+$2354) had higher 90-day reimbursements. Malnutrition (+$10,673), alcohol use or dependence (+$6273), Parkinson disease (+$4892), cerebrovascular accident or stroke (+$4637), and hyper-coagulopathy (+$4463) had the highest reimbursements. In general, states in the South and Midwest had lower 90-day reimbursements associated with upper-extremity arthroplasty. CONCLUSIONS: Under the DRG-based model piloted by the Centers for Medicare & Medicaid Services, providers and hospitals would be reimbursed the same amount regardless of the type of surgery (ATSA vs. hemiarthroplasty vs. TEA), patient comorbidity burden, and diagnosis and indication for surgery (fracture vs. degenerative pathology), despite each of these factors having different resource utilization and associated reimbursements. Lack of risk adjustment for fracture indications leads to strong financial disincentives within this model.

BACKGROUND: There have been conflicting results when comparing outcomes of open vs. arthroscopic anterosuperior rotator cuff repairs with subscapularis involvement. The purpose of this study was to evaluate midterm outcome differences and complications following open vs. arthroscopic repair of rotator cuff tears involving the subscapularis by a single surgeon. METHODS: This was a retrospective review of 57 rotator cuff repairs involving the subscapularis performed by a single surgeon over a 10-year period. During this time, the surgeon transitioned from open to arthroscopic repair. Preoperative and postoperative range of motion, lift-off test, belly press test, and American Shoulder and Elbow Surgeons (ASES) Standardized Shoulder Assessment form scores were measured. RESULTS: Eighteen patients had open procedures and 39 had arthroscopic repair. The mean preoperative ASES score for the open group was 39 and postoperatively was 79. The mean preoperative ASES score for the arthroscopic group was 44 and improved to 80 postoperatively. There was no significant difference in score or change in score between the 2 groups (P > .05). There was only 1 complication. It occurred in the open group and was a superficial wound dehiscence. CONCLUSIONS: This study demonstrated no outcome differences between open and arthroscopic rotator cuff repair involving the subscapularis, even with large subscapularis tears. Both techniques significantly improved shoulder function. Arthroscopic and open rotator cuff repairs including the subscapularis are relatively safe procedures, and either technique is an acceptable option.

BACKGROUND: As the current health care system evolves toward cost-containment and value-based approaches, evaluating trends in physician reimbursements will be critical for assessing and ensuring the financial stability of shoulder surgery as a subspecialty. METHODS: The Medicare Physician Fee Schedule Look-up Tool was used to retrieve average reimbursement rates for 39 shoulder surgical procedures (arthroscopy with or without repair, arthroplasty, acromioclavicular or clavicular open reduction-internal fixation, fixation for proximal humeral fracture and/or shoulder dislocation, open rotator cuff repair or tendon release and/or repair, and open shoulder stabilization) from 2002 to 2018. All reimbursement data were adjusted for inflation to 2018 dollars. RESULTS: After adjusting for inflation to 2018 dollars, average reimbursement for all included procedures decreased by 26.9% from 2002 to 2018. After stratifying the analysis by 3 distinct time groups, we observed that reimbursement decreases were the most significant prior to 2010. However, reimbursement rates still declined by an average of 2.9% from 2010 to 2014 and 7.2% from 2014 to 2018. Arthroscopic rotator cuff repair, capsulorrhaphy, and biceps tenodesis experienced smaller declines in reimbursement than their open-surgery counterparts. CONCLUSION: Medicare physician reimbursements for shoulder surgical procedures have decreased over time. Health care policy makers need to understand the impact of decreasing reimbursements to develop agreeable financial policies that will not only ensure provider satisfaction but also maintain access to care for patients.

BACKGROUND: This study characterized the prevalence and risk factors of inpatient and outpatient postoperative falls in patients undergoing elective shoulder arthroplasty. METHODS: A retrospective chart review of 198 patients undergoing anatomic or reverse total shoulder arthroplasty or hemiarthroplasties at one institution between 2015 and 2017 was reviewed to determine the prevalence of inpatient and outpatient falls up to 90 days after discharge. Univariate and multivariate analyses were conducted to assess potential risk factors for postoperative falls including demographics, indication for surgery, surgical procedure, medical history, length of hospital stay, perioperative hemoglobin, need for transfusion, and discharge disposition. RESULTS: There were 23 falls in 22 patients within a 90-day postoperative period. The inpatient fall rate was 1.0% (2 of 198). The outpatient fall rate was 10.6% (21 of 198). Outpatient falls resulted in emergency department evaluation in 23.8% of cases (5 of 21), readmission in 19.0% (4 of 21), injury to an anatomic site other than the shoulder in 19.0% (4 of 21), and injury at the surgical site (eg, periprosthetic humeral fracture) in 4.8% (1 of 21). No significant risk factors were identified for inpatient falls. Independent risk factors for an outpatient fall were female sex (adjusted odds ratio [aOR] = 4.79; 95% confidence interval [CI]: 1.32, 17.4; P = .007), increased length of hospital stay (aOR = 1.23; 95% CI: 1.04, 1.45; P = .02), and history of a movement disorder (aOR = 7.20; 95% CI: 1.22, 42.6; P = .03). CONCLUSION: A high outpatient fall rate of 10.6% within 90 days after discharge raises the concern that falls after shoulder arthroplasty are significantly higher than previously reported.

BACKGROUND: Rotator cuff disease is the most common pathology of the shoulder, responsible for approximately 70% of clinic visits for shoulder pain. However, no consensus exists on the optimal treatment. The aim of this study was to analyze level I and II research comparing operative versus nonoperative management of full-thickness rotator cuff tears. METHODS: A literature search was performed, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, to identify level I and II studies comparing operative versus nonoperative treatment of rotator cuff tears. Two independent researchers reviewed a total of 1013 articles. Three studies qualified for inclusion. These included 269 patients with 1-year follow-up. The mean age ranged from 59 to 65 years. Clinical outcome measures included the Constant score and visual analog scale (VAS) score for pain. Meta-analysis, using both fixed- and random-effects models, was performed on pooled results to determine overall significance. RESULTS: Statistically significant differences favoring surgery were found in both Constant and VAS scores after 1 year, with mean differences of 5.64 (95% confidence interval, 2.06 to 9.21; P = .002) and -1.08 (95% confidence interval, -1.56 to -0.59; P < .0001), respectively. CONCLUSION: There was a statistically significant improvement in outcomes for patients managed operatively compared with those managed nonoperatively. The differences in both Constant and VAS scores were small and did not meet the minimal difference considered clinically significant. Larger studies with longer follow-up are required to determine whether clinical differences between these treatments become evident over time.

BACKGROUND: Biceps tenodesis reduces the incidence of Popeye deformity occurring with tenotomy, but pain may occur with tenodesis superior to or within the bicipital groove. Arthroscopic suprapectoral tenodesis is an attractive alternative. The purpose of this study was to establish landmarks for arthroscopic suprapectoral tenodesis and determine the appropriate fixation point to optimize muscle tension. METHODS: Twelve fresh cadaveric shoulders were dissected. Urethane polymer was injected into the axillary artery. The position of the anterior branch of the axillary nerve was marked. The transverse humeral ligament was split, exposing the biceps (long head of the biceps [LHB]) from its origin to the pectoralis major tendon (PMT). The intra-articular portion was released. Measurements were taken from the proximal tendon to described landmarks. RESULTS: The mean length of the intra-articular LHB was 2.53 cm (range, 1.72-3.55 cm). The mean distance from the LHB origin to the inferior lesser tuberosity (LT) was 5.58 cm (range, 4.02-6.87 cm), and that to the superior border of the PMT was 8.46 cm (range, 6.46-10.78 cm). The suprapectoral tenodesis zone (inferior LT to superior PMT) was 2.96 cm (range, 1.54-4.40 cm). In all specimens, a branch of the anterior humeral circumflex arose medial to the LHB and distal to the LT and crossed the suprapectoral zone from medial to lateral at 1.49 ± 0.42 cm proximal to the PMT, approximately at the level of the axillary nerve. The musculocutaneous nerve was on average 3.06 cm (range, 1.86-3.76 cm) from the tenodesis zone. CONCLUSION: A branch of the anterior humeral circumflex is a reliable landmark for identifying the mid-suprapectoral zone. The distance from the proximal LHB tendon to this crossing vessel averaged 6.32 cm in female specimens and 8.28 cm in male specimens. These findings allow appropriate tensioning of the LHB during arthroscopic suprapectoral tenodesis.

BACKGROUND: The purpose of this study was to assess the long-term outcome of the open Bankart repair for traumatic, recurrent anterior dislocation of the shoulder by evaluation of recurrence, range of motion, return to sports, arthritis, patient satisfaction, and outcome measures. METHODS: Of 162 patients, 127 patients (mean age, 31 years) were evaluated at a mean follow-up of 17.1 years (5-24) after undergoing an open Bankart repair using suture anchors. An independent orthopedic surgeon obtained a history and examined each for range of motion. Radiographs for arthritis and osteolysis were obtained unless the patient refused. Questionnaires including return to sports and function as well as satisfaction and outcome measures were completed by all patients. RESULTS: There was 1 recurrent dislocation (0.8%) and 1 recurrent subluxation (0.8%) but no pain or apprehension. All remaining shoulders were stable. Compared with the normal shoulder, there was statistical difference in external rotation in abduction and at the side as well as in internal rotation but not in forward elevation or abduction. However, no patient considered any measurable loss functionally significant. Of 107 patients who participated in sports, 98 returned to the sport; 7 of the remaining 9 discontinued for reasons other than the shoulder. There were 91 patients who agreed to radiography; 48 had normal findings, 34 had mild arthrosis, 9 had moderate arthrosis, and none had severe arthrosis. Mean postoperative outcome scores were as follows: American Shoulder and Elbow Surgeons, 93.53; Rowe, 91.41; and Western Ontario Shoulder Instability Index, 327.7. There were 125 patients who were satisfied and would undergo the procedure again. CONCLUSION: The open Bankart procedure remains the standard by which other techniques can be measured for treatment of recurrent, traumatic anterior dislocation of the shoulder.

BACKGROUND: The purpose of this study was to analyze the pathomorphology of proximal humeral fractures to determine relevant and reliable parameters for fracture classification. METHODS: A total of 100 consecutive acute proximal humeral fractures in adult patients were analyzed by 2 non-independent observers from a single shoulder department using a standardized protocol based on biplane radiographs and 3-dimensional computed tomography scans. A fracture classification system based on the most reliable key features of the pathomorphologic analysis was created, and its reliability was tested by 6 independent shoulder experts analyzing another 100 consecutive proximal humeral fractures. RESULTS: The head position in relation to the shaft (varus, valgus, sagittal deformity) and the presence of tuberosity fractures showed a higher interobserver reliability (κ > 0.8) than measurements for medial hinge, shaft, and tuberosity displacement, metaphyseal extension, fracture impaction, as well as head-split component identification (κ < 0.7). These findings were used to classify nondisplaced proximal humeral fractures as type 1, fractures with normal coronal head position but sagittal deformity as type 2, valgus fractures as type 3, varus fractures as type 4, and fracture dislocations as type 5. The fracture type was further combined with the fractured main fragments (G for greater tuberosity, L for lesser). Interobserver and intraobserver reliability analysis for the fracture classification revealed a κ value (95% confidence interval) of 0.700 (0.631-0.767) and 0.917 (0.879-0.943), respectively. CONCLUSION: The new classification system with emphasis on the qualitative aspects of proximal humeral fractures showed high reliability when based on a standardized imaging protocol including computed tomography scans.

Proximal humeral fractures are becoming increasingly common in individuals older than 60 years, with only fractures of the hip and distal radius occurring with a higher frequency. Most proximal humeral fractures can be managed without surgery; however, if a fracture is displaced or angulated, surgical treatment may be required. There are four main options for the surgical management of proximal humeral fractures: minimally invasive percutaneous reduction and fixation, open reduction and periarticular plating, hemiarthroplasty, and reverse total shoulder arthroplasty.

BACKGROUND: The purpose of this study was to analyze the outcome of open Bankart repair for failed stabilization surgery at a mean follow-up of >10 years. MATERIALS AND METHODS: Thirty patients underwent revision open Bankart repair by a single surgeon for failed prior stabilization surgery, with a standard technique and postoperative rehabilitation. All patients were referred by other surgeons. Evaluation was by an independent examiner, at a mean follow-up of 10.2 years. Evaluation included a history, physical examination for range of motion, outcome scores, recurrence, return to athletics, and radiographic examination. RESULTS: All cases had persistent Bankart and Hill-Sachs lesions. Failures included 14 patients with a failed single arthroscopic Bankart repair; 1 patient with 2 failed arthroscopic Bankart repairs; 1 patient with an arthroscopic failure and an open Bankart repair; 7 patients with failed open Bankart repairs; and 1 patient with a failed open Bankart repair, then a failed arthroscopic attempt. Two patients had had thermal capsulorrhaphy; 2 others had staple capsulorrhaphy, 1 with an open capsular shift and 1 after a failed arthroscopic Bankart repair, an open Bankart repair, and then a coracoid transfer. All arthroscopic Bankart repairs had anchors placed medial and superior on the glenoid neck. Mean motion loss compared with the normal contralateral side was as follows: elevation 1.15°, abduction 4.2°, external rotation at the side 3.2°, external rotation in abduction 5.1°, and internal rotation 0.6 vertebral levels (NS). No patient had an apprehension sign, pain, or instability. Of 23 who played sports, 22 resumed after. Outcomes scores were as follows: American Shoulder and Elbow Surgeons, 89.44; Rowe, 86.67; Western Ontario Shoulder Instability Index, 476.26. On radiographic examination, there were 13 normal radiographs and 7 with mild, 2 with moderate, and 0 with severe arthritic changes. CONCLUSION: The open Bankart repair offers a reliable, consistently successful option for revision of failed stabilizations.

BACKGROUND: Anterior shoulder instability can result in bone loss of both the anterior glenoid and the posterior humerus. Bone loss has been shown to lead to increased failure postoperatively and may necessitate more complex surgical procedures, resulting in worse clinical outcomes and posttraumatic arthritis. HYPOTHESIS/PURPOSE: The purpose of this study was to investigate predictors of glenoid and humeral head bone loss in patients undergoing surgery for anterior shoulder instability. It was hypothesized that male sex, contact sport participation, traumatic dislocation, and higher number of instability events would be associated with greater bone loss. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: A total of 892 patients with anterior shoulder instability were prospectively enrolled in the Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Instability cohort. The presence and amount of anterior glenoid bone loss and accompanying Hill-Sachs lesions were quantified. Descriptive information and injury history were used to construct proportional odds models for the presence of any bone defect, for defects >10% of the anterior glenoid or humeral head, and for combined bony defects. RESULTS: Anterior glenoid bone loss and Hill-Sachs lesions were present in 185 (20.7%) and 470 (52.7%) patients, respectively. Having an increased number of dislocations was associated with bone loss in all models. Increasing age, male sex, and non-White race were associated with anterior glenoid bone defects and Hill-Sachs lesions. Contact sport participation was associated with anterior glenoid bone loss, and Shoulder Actitvity Scale with glenoid bone loss >10%. A positive apprehension test was associated with Hill-Sachs lesions. Combined lesions were present in 19.4% of patients, and for every additional shoulder dislocation, the odds of having a combined lesion was 95% higher. CONCLUSION: An increasing number of preoperative shoulder dislocations is the factor most strongly associated with glenoid bone loss, Hill-Sachs lesions, and combined lesions. Early surgical stabilization before recurrence of instability may be the most effective method for preventing progression to clinically significant bone loss. Patients should be made aware of the expected course of shoulder instability, especially in athletes at high risk for recurrence and osseous defects, which may complicate care and worsen outcomes.

Arthroscopic instability and rotator cuff repair techniques have rapidly evolved over the past decade with expanding indications; however, there has been a corresponding increase in complications. Careful attention to detail and patient selection will result in satisfactory outcomes for most patients.

Background: Preoperative erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) ranges for several shoulder arthroplasty indications are not well understood. Purpose: We sought to compare preoperative ESR and CRP values for a variety of shoulder arthroplasty indications and evaluate risk factors for elevated preoperative ESR and CRP values. Methods: We conducted a retrospective cohort study of shoulder arthroplasty cases performed at a single academic medical institution from 2013 to 2018. Preoperative ESR and CRP values for 235 shoulder arthroplasties with various indications were recorded. Independent risk factors for elevated values (CRP > 10.0 mg/L and ESR > 30.0 mm/h) were determined via multiple variable logistic regression. Results: Patients undergoing shoulder arthroplasty for osteoarthritis had an ESR (mean ± SD) of 22.6 ± 17.8, with 29.8% of patients elevated, and a CRP of 6.5 ± 6.4, with 25.5% of patients elevated. Arthroplasty for acute fracture and prosthetic joint infection (PJI) had higher preoperative ESR and CRP values. Multivariate analysis identified several predictors of elevated ESR, including infection, acute fracture, diabetes, and female sex. It also identified predictors of elevated CRP, including infection, acute fracture, and younger age. Conclusions: Preoperative ESR and CRP values may be elevated in 25% to 30% of patients undergoing primary shoulder arthroplasty. Arthroplasty for both acute fracture and PJI, along with several other patient factors, was associated with elevated preoperative ESR and CRP. Thus, routine collection of ESR and CRP preoperatively may not be of benefit, as elevated values are common. Further study is warranted.
