RESUMEN
INTRODUCTION: The role of the subscapularis (Ssc) tendon does not yet have a well-defined role in RSA. The purpose of the present study was to evaluate if the repair of the Ssc in RSA improves overall clinical and radiographic results and if it has the same results using a medialized design humeral stem compared to a lateralized design. METHODS: Eighty-four consecutive patients undergoing RSA were retrospectively analyzed. Nine patients were lost at FU. Two implants with similar glenosphere design and different stem design (medialized and lateralized) were used. The Ssc was repaired in case of good quality of the fibers and reducibility without tension intraoperatively. Patients were divided into four groups for data analysis depending on whether they had received a medialized or lateralized design and Ssc repair or not. Patients were reviewed at an average follow-up of 40.8 ± 13.1 months. Clinical outcome measures included Active range of motion (ROM), strength, visual analog scale (VAS), Constant-Murley score (CMS), and the American Shoulder and Elbow Surgeons score (ASES). Radiographic evaluation at final follow-up was performed to assess scapular notching, stress shielding, and radiolucent lines. RESULTS: No statistically significant clinical differences (p > 0.05) emerged between Lat/Ssc+ and Lat/Ssc-. Conversely, the patients belonging to the Med/Ssc- group reported statistically worse (p < 0.05) results than the Med/Ssc + group in terms of VAS, ASES and CMS. Statistically worse (p < .05) results in the Med/Ssc- group than in the Med/Ssc + were found also in active ROM achieved in FE, ABD, ER1 and ER2, and in the strength obtained in FE, ABD and ER2. Scapular notching was reported in 3 shoulders (15.7%) in Lat/Ssc+ group and in 7 shoulders (50%) in Lat/Ssc- group, while it was reported in 4 shoulders (14.2%) in Med/Ssc + group and in 6 shoulders (42.8%) in Med/Ssc- group. Stress shielding was observed in 6 cases in Lat/Ssc+ group (31.6%), in 8 cases in Lat/Ssc- group (57.1%), in 3 cases (10.7%) in Med/Ssc + group and 4 cases in Med/Ssc- group (28.6%). CONCLUSIONS: Patients undergoing RSA show clinical improvements at mid-term follow-up with a low rate of complications, regardless of the use of a medialized or a lateralized humeral stem design. Ssc repair is associated with better functional outcomes in the cohort of medialized stem, while it did not yield significant differences in the cohort of lateralized stem. LEVEL OF EVIDENCE: Level III; Retrospective Cohort Comparison; Treatment Study.

BACKGROUND: Lateralized onlay reverse shoulder arthroplasty (RSA) is designed to ensure better clinical functional recovery and lower rate of complications compared with Grammont medialized inlay RSA. The purpose of the present study was to compare the clinical and radiographic outcomes between these 2 different designs. METHODS: Eighty-five consecutive patients who underwent RSA were retrospectively analyzed. Nine patients were lost to follow-up, 34 received a curved onlay with a 145° neck-shaft angle (Ascend Flex group), and 42 received a long straight inlay stem with a 155° neck-shaft angle (Delta Xtend group). Patients were reviewed at an average follow-up of 46.8 ± 13.2 months (Ascend Flex group) and 36 ± 10.8 months (Delta Xtend group). Clinical outcome measures included active range of motion, strength, visual analog scale, Constant-Murley score, and the American Shoulder and Elbow Surgeons score. Radiographic evaluation at the final follow-up was performed to assess scapular notching, stress shielding, acromial or scapular fractures, heterotopic ossification, and radiolucent lines or implant loosening. RESULTS: No differences emerged between the 2 groups in terms of visual analog scale, American Shoulder and Elbow Surgeons and Constant-Murley scores, pain, function, strength, mobility, active forward elevation, active internal rotation, active external rotation at 0° and 90° of abduction, abduction, forward elevation, and external rotation strength (P = n.s.). Statistically superior active abduction was observed in the Delta Xtend group (P = .0017). Scapular notching was observed in 12 shoulders (35.2%) in the Ascend Flex group (a grade 1) and in 10 shoulders (23.8%) in the Delta Xtend group (P = n.s.). No differences emerged between the 2 groups in terms of humeral or glenoid radiolucency (P = n.s.). Higher rate of humeral stress shielding rate was observed in the Ascend flex cohort (P = n.s.). CONCLUSIONS: No statistically significant difference emerged between the 145° onlay curved stem vs. the 155° inlay straight stem according to most of the evaluated parameters. Statistically superior active abduction was observed in the 155° group although it did not affect patients' satisfaction.

BACKGROUND: Reverse shoulder arthroplasty (RSA) has been shown to reliably improve pain and functional outcomes for multiple pathologies. Despite its increasing use in the United States since its introduction in 2004, few studies have investigated long-term outcomes of this procedure. This information is vital in many ways, including durability of functional outcomes, complication profiles, and implant survivorship. METHODS: Our prospectively collected shoulder arthroplasty registry included 471 patients who had undergone RSA prior to December 31, 2010, by a single surgeon at a high-volume shoulder arthroplasty center. The study sample included 94 patients with a minimum of 10 years' follow-up, and we evaluated the indications for RSA, complications, pain, Single Assessment Numeric Evaluation (SANE), and patient satisfaction on these patients at baseline, 2-5 years, and 10 or more years of follow-up. Prosthesis survivorship was determined by Kaplan-Meier survival analysis performed with revision for any reason as the end point for all 471 patients in the study period regardless of follow-up interval. RESULTS: The 93 patients with at least 10 years of follow-up were 63% female (60) and 37% male (34), with an average age of 66±10 years at the time of RSA. There were 70 (75%) primary RSAs and 23 (25%) revision RSAs. Patient-reported outcome measures at 10 years or more included a current pain rating averaging 2±3 on a 0-10 scale and Single Assessment Numeric Evaluation (SANE) of 73±28. There was no deterioration in function or pain from midterm to long-term follow-up, as the SANE and pain score changed by less than the minimal clinically important difference or improved in 87% and 90% of patients, respectively. Overall, patients were satisfied with the RSA procedure, with 52 (56%) very satisfied, 24 (26%) satisfied, 13 (14%) dissatisfied, and 4 (4%) very dissatisfied. For the subset of 68 patients who were contacted for follow-up, 64 (94%) would have the procedure again and 4 (6%) would not. Kaplan-Meier prosthesis survival rate for all 471 RSA patients was 88% (95% confidence interval [CI] 84%-92%) at 5 years and 81% (95% CI 74%-86%) at 10 years. CONCLUSIONS: This study presents the largest American cohort of Grammont design RSA at a minimum 10-year follow-up. Although RSA provided clinically significant and durable improvements in pain and function, the complication and revision rates were higher than prior reports. Despite this, the vast majority of patients were satisfied and would have the procedure again.

The purpose of this study was to report early complications for anatomic total shoulder arthroplasty (aTSA) performed for instability arthropathy after a prior coracoid transfer procedure and compare them with those of a control group of patients following aTSA for primary osteoarthritis. A retrospective review was performed of 14 patients after aTSA with a prior coracoid transfer procedure. A control group of 42 patients with an aTSA for primary osteoarthritis were matched 3:1 according to age, sex, body mass index, comorbidities, and dominant shoulder. Chart reviews identified any complications within 1 year, in addition to blood loss and operative time in both groups. Preoperative computed tomography scans were used to determine Walch glenoid classification and Goutallier classification of the subscapularis. The mean operative time was not significantly different between the coracoid transfer cohort and the control group, and the mean estimated blood loss was only 6.9 mL greater in the coracoid transfer group. The coracoid transfer group had 2 (14.3%) patients with complications, with 1 early revision for an acute deep infection. The control group had 4 (9.5%) complications in 3 (7.1%) patients, with no early revisions. There was no statistical difference in complications between the groups (P=.618). Anatomic TSA for instability arthropathy after coracoid transfer had similar operative time, blood loss, and 1-year complication rates as those of the control group. These results provide some evidence to support the continued use of aTSA in select patients with instability arthropathy after prior coracoid transfer procedure. [Orthopedics. 2021;44(4):e482-e486.].

PURPOSE: The purpose of this study was to evaluate whether fellowship training affected trends and complications of operative clavicle fracture treatment in newly trained orthopedic surgeons. METHODS: The American Board of Orthopedic Surgery (ABOS) database was utilized to identify cases of open treatment of clavicle fractures submitted by ABOS Part-II Board Certification candidates. From 2005 to 2017, 3148 candidates performed at least one open clavicle fracture treatment. Overall, 6919 cases were included; 3516 of these had over 6 weeks of follow-up. Candidates were divided by fellowship type into 5 groups: Trauma, Sports Medicine, Hand and Upper Extremity or Shoulder, multiple, and other or no fellowship(s). Group differences were analyzed with ANOVA and Bonferroni post hoc analysis. Complications, reoperations, nonunion rates, and readmissions between groups were evaluated with Chi-squared test and logistic regression analyses. RESULTS: Case volume during the study period was significantly higher after 2007. Trauma candidates performed significantly more operations for clavicle fracture per candidate while candidates with other or no fellowship(s) performed significantly fewer operations per candidate. Patients treated by Trauma candidates were significantly older, had significantly fewer early surgical complications and significantly more early medical complications. Nonunion rates were not significantly different between groups. CONCLUSION: Candidates treated clavicle fractures surgically more often in 2007 and beyond. Trauma candidates treated older patients, had fewer early surgical complications, and had more medical complications. Reoperation, readmission and nonunion rates were not significantly different between groups.
RESUMEN
BACKGROUND: Treatment of primary osteoarthritis with glenoid dysplasia or Walch type C glenoids remains controversial. There is scant literature available on patient outcomes after anatomic shoulder arthroplasty in patients with Walch type C glenoids. The purpose of this study was to evaluate the outcomes of total shoulder arthroplasty (TSA) for Walch type C dysplastic glenoids with standard (nonaugmented) glenoid components compared with TSA for glenoids with concentric wear and minimal erosion (Walch type A1). We hypothesized that TSA performed for Walch type C dysplastic glenoids with standard glenoid components can reliably produce successful results at short- to midterm follow-up. METHODS: We identified all patients who had primary anatomic TSA performed for osteoarthritis in a prospective shoulder arthroplasty registry collected from 2004 to the present time. Twenty-nine patients met inclusion criteria of a preoperative Walch type C dysplastic glenoid, treatment with TSA using standard (nonaugmented) glenoid components, and a minimum of 2-year clinical follow-up. A matched cohort of 58 patients with a type A1 glenoid and minimum of 2-year clinical follow-up for anatomic shoulder arthroplasty served as the control group. The American Shoulder and Elbow Surgeons (ASES) score, the Single Assessment Numeric Evaluation (SANE), patient satisfaction, complications, and revisions were evaluated in both cohorts. RESULTS: The mean follow-up for this study was 4.5 years (standard deviation, 2.6 years; range, 2-10 years). Baseline measures were not significantly different between the Walch type C dysplastic group and the matched type A1 cohort (all P > .05). Both groups showed significant improvements in ASES, ASES pain, and SANE scores from baseline to the final follow-up (all P < .001). The Walch type C group had no significant differences in ASES score (P = .118), ASES pain (P = .730), or SANE score (P = .168) compared with the matched type A1 cohort. The complication rate of patients with a type C glenoid was 14% (4 of 29) with a 7% (2 of 29) revision rate. Similarly, the complication rate for the A1 matched cohort was 17% (10 of 58) with a 12% (7 of 58) revision rate. Both groups had high patient satisfaction without statistical differences (P = .549). In addition, there were no differences in the rate of radiographic lucencies or Lazarus scores (P = .222). CONCLUSIONS: Anatomic TSA reliably produced clinically significant improvements in pain and function and similar short- to midterm outcomes in patients with Walch type C dysplastic glenoids compared with patients with type A1 glenoids. Anatomic TSA with standard (nonaugmented) glenoid components should remain an option in patients with Walch type C dysplastic glenoids despite emerging treatment options including augmented glenoid components and reverse TSA.

BACKGROUND: Variations in glenoid morphology affect surgical treatment and outcome of advanced glenohumeral osteoarthritis (OA). The purpose of this study was to assess the inter- and intraobserver reliability of the modified Walch classification using 3-dimensional (3D) computed tomography (CT) imaging in a multicenter research group. METHODS: Deidentified preoperative CTs of patients with primary glenohumeral OA undergoing anatomic or reverse total shoulder arthroplasty (TSA) were reviewed with 3D imaging software by 23 experienced shoulder surgeons across 19 institutions. CTs were separated into 2 groups for review: group 1 (96 cases involving all modified Walch classification categories evaluated by 12 readers) and group 2 (98 cases involving posterior glenoid deformity categories [B2, B3, C1, C2] evaluated by 11 readers other than the first 12). Each case group was reviewed by the same set of readers 4 different times (with and without the glenoid vault model present), blindly and in random order. Inter- and intraobserver reliabilities were calculated to assess agreement (slight, fair, moderate, substantial, almost perfect) within groups and by modified Walch classification categories. RESULTS: Interobserver reliability showed fair to moderate agreement for both groups. Group 1 had a kappa of 0.43 (95% confidence interval [CI]: 0.38, 0.48) with the glenoid vault model absent and 0.41 (95% CI: 0.37, 0.46) with it present. Group 2 had a kappa of 0.38 (95% CI: 0.33, 0.43) with the glenoid vault model absent and 0.37 (95% CI: 0.32, 0.43) with it present. Intraobserver reliability showed substantial agreement for group 1 with (0.63, range 0.47-0.71) and without (0.61, range 0.52-0.69) the glenoid vault model present. For group 2, intraobserver reliability showed moderate agreement with the glenoid vault model absent (0.51, range 0.30-0.72), which improved to substantial agreement with the glenoid vault model present (0.61, range 0.34-0.87). DISCUSSION: Inter- and intraobserver reliability of the modified Walch classification were fair to moderate and moderate to substantial, respectively, using standardized 3D CT imaging analysis in a large multicenter study. The findings potentially suggest that cases with a spectrum of posterior glenoid bone loss and/or dysplasia can be harder to distinguish by modified Walch type because of a lack of defined thresholds, and the glenoid vault model may be beneficial in determining Walch type in certain scenarios. The ability to reproducibly separate patients into groups based on preoperative pathology, including Walch type, is important for future studies to accurately evaluate postoperative outcomes in TSA patient cohorts.

BACKGROUND: Reverse shoulder arthroplasty (RSA) has gained popularity in elderly patients because of its limited reliance on rotator cuff function and high survivorship rates. However, although there are theoretical advantages of RSA over anatomic total shoulder arthroplasty (TSA) in elderly patients, there is little data to guide surgeons on implant selection in this population. METHODS: Patients were identified from our prospectively collected shoulder arthroplasty registry. We included patients between the age of 50 and 89 years who underwent primary TSA for osteoarthritis with intact rotator cuff or primary RSA for cuff tear arthropathy. The minimum and mean clinical follow-up was 2 and 3.1±1.3 years, respectively. Four patient groups were formed for analysis: (1) TSA age 50-69 years (n=274), (2) TSA age 70-89 years (n=208), (3) RSA age 50-69 years (n=81), and (4) RSA age 70-89 years (n=104). We evaluated age group differences in pain, Constant score, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score, patient satisfaction, complications, and revisions. RESULTS: All groups showed significant improvements from preoperative to final follow-up for all outcome measures (P < .001). Visual analog scale for pain average score decreased from 5.8 preoperatively to 1.1, with no significant differences between groups (TSA P = .180; RSA P = .103). Final ASES scores and improvement from preoperative ASES score between the age groups were not significantly different (TSA P = .520; RSA P = .065). There were no significant differences in outcomes between TSA in patients older than 70 years vs. patients younger than 70 years (all P > .05); however, older RSA patients reported better function during activities of daily living (P = .020) than their younger counterparts. Patients undergoing TSA had a lower revision rate of 3.9% compared with 8.1% in the RSA group (P = .043). CONCLUSIONS: TSA and RSA are reliable procedures for patients older than 70 years, and have comparable results to their respective patient cohorts younger than 70 years. Although some surgeons anecdotally advocate for RSA in patients older than 70 years with primary osteoarthritis and an intact rotator cuff, we found no difference in outcomes for TSA based on our age cutoff. Given satisfactory results following TSA in patients 70 years of age and older, we do not routinely perform RSA for primary osteoarthritis with an intact rotator cuff solely based on age. Further studies and longer follow-up are needed to determine the optimal implant selection for elderly patients with primary osteoarthritis.

BACKGROUND: Although the rate of periprosthetic joint infection following shoulder arthroplasty is low, it is a morbid and costly complication. Airborne particulates have long been recognized as a potential source of wound contamination, and operating room-mounted and smaller localized laminar airflow devices have been developed to minimize airborne particulates. This randomized controlled trial evaluated the effectiveness of a localized laminar flow device in reducing the intrusion of ambient airborne particles and bacteria into the surgery site during shoulder arthroplasty as measured by overall particle counts and colony-forming units (CFUs). METHODS: Patients undergoing primary anatomic or reverse shoulder arthroplasty were eligible for participation. After providing informed consent, patients were randomly assigned to the Air Barrier System (ABS) group or control group. For all patients, the ABS was placed on the surgical field; however, it was only turned on by the technician for those randomized to the ABS. Study participants, surgeons, and surgical staff were blinded to group assignment. Bacterial CFUs were collected from within 5 cm of the surgical wound every 10 minutes, whereas airborne particulates were collected every minute. Poisson regression models were used to determine whether differences existed in CFUs and particulate counts between the ABS and control groups. RESULTS: A total of 43 patients were randomized into the ABS (n = 21) or control (n = 22) group. Surgical time (P = .53) and the average staff count (P = .16) in the operating room did not differ between groups. Poisson regression showed that the ABS group had significantly lower CFUs (ß = -0.583, P < .001) along with surgical time and particulates with a diameter ≥ 5 µm. Staff count and particulates with a diameter < 5 µm were not significant predictors of CFUs. Infection was not a primary outcome; however, no postoperative infections have been reported in either study group with a minimum of 1-year follow-up for all patients. DISCUSSION: This double-blinded, randomized trial demonstrated that a localized laminar flow device dramatically reduced the count of CFUs in the air directly above the wound and beneath the ABS (adjusted for the number of operating room personnel and surgical time). The use of the device was not associated with a longer case duration; however, some additional setup time was required prior to surgical incision to place the device. Further study is required to determine the clinical implications of this finding-specifically, whether such devices result in lower rates of periprosthetic joint infection after shoulder arthroplasty.

BACKGROUND: Glenoid component malpositioning and glenoid component retroversion have been associated with higher rates of radiolucencies, raising concerns about its implications on glenoid loosening and ultimate failure of anatomic total shoulder arthroplasty (TSA). Although there is literature regarding the relative advantages of techniques to address posterior glenoid bone loss, we are not aware of studies comparing outcomes of TSA on these challenging Walch type B2 glenoids vs. more common A1 glenoids. The purpose of this study is to compare outcomes of TSA performed on A1 glenoids and B2 glenoids treated with asymmetric glenoid reaming. METHODS: We identified 1045 shoulders that had primary TSAs performed for osteoarthritis in a prospective shoulder arthroplasty registry. Two hundred eighty-nine shoulders met inclusion criteria of a preoperative Walch type A1 (178) or B2 (111) glenoid morphology, treatment with TSA, asymmetric reaming in the B2 group, and a minimum of 2-year clinical and radiographic follow-up. Postoperative radiographs were assessed for lucencies, and patient-reported outcome measures were collected at all follow-up visits. RESULTS: Follow-up averaged 40 ± 15 months for all patients, and more men presented with a B2 glenoid (80 of 111; 72%) compared with A1 (101 of 178; 57%) (P = .009). Age at surgery (P = .166), dominant-sided surgery (P = .281), body mass index (P = .501), smoking (P = .155), preoperative opioid use (P = .154), and diabetes (P = .331) were not significantly different between groups. Both groups had similar Constant Strength scores preoperatively (A1: 4.7 ± 7.1, and B2: 4.3 ± 7.3) but the B2 group improved significantly more at final follow-up (A1: 10.3 ± 6.2 vs. B2: 12.7 ± 6.7, P = .005). The Total Constant score was also significantly better at follow-up in the B2 glenoid group (P = .039). All other Constant subscales, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), and Single Assessment Numerical Evaluation (SANE) measures showed significant improvement preoperatively to final follow-up (all P <.001) but there were no significant differences between the A1 and B2 glenoid groups (all P > .05). A similar proportion of patients rated their satisfaction as either very satisfied or satisfied between the A1 (160; 90%) and B2 (100; 90%) (P = .613). Lazarus scores were also similar between the A1 and B2 groups (P = .952) as were the rates of humeral radiolucent lines (P = .749) and humeral osteolysis (P = .507). CONCLUSIONS: Although patients with B2 glenoids may present a more technically challenging anatomic total shoulder arthroplasty, treatment with concurrent asymmetric glenoid reaming produced similar, successful clinical and radiographic early to midterm outcomes for patients undergoing TSA compared with A1 glenoids. Additional follow-up on this cohort will be important to confirm the durability of these early results.

The effect of preoperative opioid use in orthopedic patients has been highlighted. Numerous studies have identified worse patient outcomes with pre-operative opioid use; however, there is currently no information identifying risk factors for preoperative opioid use in the total shoulder arthroplasty (TSA) population. The purpose of this study was to determine risk factors for preoperative opioid use in patients undergoing primary anatomic TSA for primary osteoarthritis (OA) and to determine baseline preoperative patient-reported outcomes (PROs) in preoperative opioid users compared with nonopioid users. The authors studied 982 TSAs performed for primary glenohumeral joint OA in a prospective TSA registry. Patient demographic and clinical characteristics were prospectively assessed and included age; sex; socioeconomic status (SES); smoking status; body mass index (BMI); and history of chronic back pain, depression, diabetes mellitus, and heart disease. Preoperative PROs, range of motion measurements, and preoperative opioid use for shoulder pain were assessed. Overall, 254 (25.9%) of 982 total patients were taking preoperative opioids for shoulder pain in the setting of primary OA. Female sex (P=.023), younger age (P=.019), obesity (BMI >30 kg/m2) (P=.043), chronic back pain (P<.001), and lower SES (P=.002) were associated with increased preoperative opioid use following multivariate logistic regression. Patients with opioid use had significantly worse preoperative pain scores (P<.001), American Shoulder and Elbow Surgeons scores (P<.001), and total Constant scores (P<.002) compared with the non-opioid group.

BACKGROUND: Many surgeons are concerned about reports of increased complications, worse outcomes, and early failures in patients undergoing anatomic total shoulder arthroplasty after coracoid transfer. The purpose of this study was to evaluate minimum 2-year outcomes following anatomic total shoulder arthroplasty for instability arthropathy with a prior coracoid transfer procedure and compare them with a matched cohort of patients undergoing total shoulder arthroplasty for primary osteoarthritis. METHODS: We identified 11 primary anatomic total shoulder arthroplasties performed by a single surgeon for instability arthropathy with a prior coracoid transfer procedure with a minimum of 2 years' follow-up (mean, 58 ± 35 months). A matched cohort of 33 patients with a total shoulder arthroplasty for primary osteoarthritis served as the control group. The American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE) score, patient satisfaction, complications, and revisions were evaluated in both cohorts. RESULTS: The coracoid transfer cohort showed no difference in the final ASES score (88 vs. 82, P = .166) or SANE score (85 vs. 67, P = .120) vs. the matched cohort. The postoperative ASES pain score (45 vs. 41, P = .004) was higher in the coracoid transfer cohort, but the mean improvement from preoperative to postoperative values for the ASES score (P = .954), ASES pain score (P = .183), and SANE score (P = .293) was no different between cohorts. Both cohorts had high patient satisfaction without a statistically significant difference (P = .784). CONCLUSION: At early- to mid-term follow-up, total shoulder arthroplasty performed after a coracoid transfer demonstrated similar results to total shoulder arthroplasty performed for primary osteoarthritis. Longer follow-up and larger patient cohorts will provide further insights and highlight any potential differences in outcomes or revision rates.

BACKGROUND: Total shoulder arthroplasty (TSA) with an anatomic or reverse prosthesis is a commonly used and successful treatment option for many degenerative shoulder conditions. There is an increasing trend toward fellowship training and subspecialization in newly trained orthopedic surgeons. The literature also suggests that subspecialization and high volume are associated with better clinical outcomes. The purpose of this study was to evaluate the effects of fellowship training on the trends and outcomes of TSA in board-eligible orthopedic surgeons. METHODS: The American Board of Orthopaedic Surgery database was used to identify primary TSA cases performed for osteoarthrosis submitted by American Board of Orthopaedic Surgery Part II Board Certification candidates. Candidates were grouped based on fellowship training and subspecialty examination being taken. Groups were analyzed with analysis of variance and Bonferroni post hoc analysis to evaluate significant differences between groups for a number of candidates, cases per candidate, and patient age/sex. Differences in complications, reoperations, and readmissions were statistically evaluated with χ2 tests and multivariate logistic regression analysis. RESULTS: From 2010 to 2017, 854 candidates performed at least 1 primary TSA (anatomic or reverse) after a diagnosis of osteoarthritis and 2720 submitted cases met inclusion criteria. Candidates completing a Shoulder fellowship performed significantly more TSAs per candidate compared with all other groups (Shoulder = 8.0 ± 6.2, Sports Medicine = 2.4 ± 2.1, Hand and Upper Extremity = 2.9 ± 2.9, General Orthopedics = 2.4 ± 2.3, P < .001). The Shoulder fellowship group had significantly lower complication rates (17.9%) as compared with the Sports Medicine fellowship (23.7%, P = .008) and Hand and Upper Extremity fellowship (25.0%, P = .008) groups. CONCLUSIONS: Shoulder fellowship-trained surgeons performed significantly more TSAs per year than other groups, with a lower complication rate when compared with other fellowship-trained candidates. Fellowship type had no effect on reoperation or readmission rates.

Osteochondritis dissecans (OCD) of the capitellum is a relatively rare condition, with a higher incidence in adolescents who participate in repetitive overhead sports. The surgical treatment approach for this uncommon problem has varied from microfracture, loose body removal, abrasion chrondroplasty, lesion fixation, osteochondral allograft transplantation surgery, and osteochondral autologous transplantation surgery. The purpose of this study is to present the authors' preferred surgical technique for the treatment of unstable OCD lesions of the capitellum with osteochondral autologous transplantation surgery using autograft from the ipsilateral knee.

BACKGROUND: Numerous studies have identified differences in patient-reported outcome scores and complication rates based on various measures of socioeconomic status (SES); however, there is limited information regarding the role of SES in the shoulder arthroplasty cohort. The purpose of this study was to characterize the role of SES in patients undergoing primary anatomic total shoulder arthroplasty (TSA) for primary glenohumeral osteoarthritis (OA). METHODS: We identified 1,045 patients who had primary TSA done for OA in a prospective shoulder arthroplasty registry, and 982 patients met inclusion criteria. We prospectively assessed patient demographics, comorbidities, patient-reported outcome scores, range of motion, and preoperative opioid use. Each patient was assigned to a quartile according to the Area Deprivation Index using their home address as a measure of SES. RESULTS: The most disadvantaged patients (lower SES) reported to our center with a higher body mass index and higher rates of preoperative opioid use and diabetes. Patients in the most disadvantaged quartile reported more preoperative pain (Constant-Pain and American Shoulder and Elbow Surgeons [ASES]-Pain) and lower function (Constant-ADL, Constant-Total, and ASES). Multivariate regression identified that male patients and advanced age at surgery had better reported ASES pain scores, while preoperative opioid use, chronic back pain, and the most disadvantaged quartile were associated with worse ASES pain scores. CONCLUSION: Lower SES correlates with worse preoperative function and pain in patients undergoing anatomic TSA for primary glenohumeral OA. Providers should be cognizant of the potential impact of SES when evaluating quality metrics for patients with primary glenohumeral OA. LEVEL OF EVIDENCE: Level 3, cross-sectional study.

The arthroscopic Latarjet has been proposed in the past decade to reduce the rate of bone block malpositioning, decrease soft-tissue damage associated with open approach, and possibly decrease intraoperative complications. Several recent studies have reported similar or even superior results with arthroscopic Latarjet compared with those achieved with open technique. However, arthroscopic Latarjet is known to be more technically demanding and some feel that it should be performed by expert shoulder surgeons with advanced arthroscopic skills. Surgical innovations should be adopted when they have potential advantages for patients. Despite the initial challenges and learning curve of arthroscopic Latarjet, experience and technical skills may reduce the rate of intraoperative complications for this technically demanding procedure.

BACKGROUND: There is limited information assessing outcomes after total shoulder arthroplasty (TSA) with a press-fit short stem. The purpose of this study was to evaluate early clinical and radiographic outcomes and complications after TSA with an anatomic press-fit short stem. METHODS: We identified 118 TSAs completed with press-fit short stem and minimum 2-year follow-up; 85 of these patients had a grit-blasted (GB) short stem placed, whereas 33 patients had short stems with proximal porous coating (PPC). Shoulder function scores, active mobility measurements, and radiographs were assessed. RESULTS: The average age at surgery was 66.7 years, with average follow-up of 3 years. Significant improvements were noted for all shoulder function scores and active mobility measurements from the preoperative state to final follow-up (P < .001). There was no stem loosening in any patients with minimum 2-year follow-up; however, 3 female patients with GB stems had gross loosening of their humeral components before 1 year, 2 requiring revision. Radiolucent lines around the humeral component were found in 5.9% without evidence of loosening. Osseous resorption at the medial cortex was noted in 9.3%. Of patients with PPC stems, no patients were observed to have radiolucent lines compared with 8.2% in the GB group (P = .09). CONCLUSION: TSAs with anatomic press-fit short stem showed significant clinical improvements from the preoperative state to final short-term follow-up, with few complications and minimal radiographic changes. Lack of PPC may contribute to early loosening in patients with poor bone quality. The authors now use a short stem with PPC.

BACKGROUND: Radiographic lucency of the glenoid component remains a problem after cement fixation in primary total shoulder arthroplasty. Glenoid component design likely contributes to rates of glenoid lucency. The purpose of this study was to prospectively compare radiographic lucency between a finned, cementless central pegged glenoid component (CL component) and a conventional cemented pegged glenoid component (P component) on immediate postoperative and minimum 2-year follow-up radiographs. METHODS: Fifty-four patients undergoing total shoulder arthroplasty were prospectively randomized to receive an all-polyethylene CL component or a conventional all-polyethylene P component. Three raters graded glenoid lucency and bone interdigitation on immediate postoperative and latest follow-up radiographs. Patients who had undergone revision surgery or had died before evaluation were excluded. Minimum 2-year follow-up was required for inclusion of radiographic evaluation. RESULTS: Fifty patients met inclusion criteria; 42 patients (84%; 20 CL and 22 P) were available for follow-up with the original glenoid implant in place. The mean follow-up duration was 35 months (24-64 months). There were no significant differences in glenoid radiolucency between CL (1/20 [5%]) and P (2/22 [9%]) components at last follow-up (P = .999). Five patients (25%) in the CL group had bone interdigitation. No instances of aseptic glenoid loosening occurred. CONCLUSION: There were no significant differences in the rate of glenoid lucency between the 2 groups at immediate or an average 35-month follow-up. Both techniques appear to be viable options for initial glenoid component fixation, with CL components allowing possible osseointegration, imparting potential long-term stability.

BACKGROUND: Glenoid component loosening remains a significant issue after anatomic shoulder arthroplasty. Pegged glenoid components have shown better lucency rates than keeled components in the short term; however, midterm to long-term results have not fully been determined. We previously reported early outcomes of the current randomized controlled group of patients, with higher glenoid lucency rates in those with a keeled glenoid. The purpose of this study was to evaluate the radiographic and clinical outcomes of these components at minimum 5-year follow-up. METHODS: Fifty-nine total shoulder arthroplasties were performed in patients with primary glenohumeral osteoarthritis. Patients were randomized to receive either a pegged or keeled glenoid component. Three raters graded radiographic glenoid lucencies. Clinical outcome scores and active mobility outcomes were collected preoperatively and at yearly postoperative appointments. RESULTS: Of the 46 shoulders meeting the inclusion criteria, 38 (82.6%) were available for minimum 5-year radiographic follow-up. After an average of 7.9 years, radiographic lucency was present in 100% of pegged and 91% of keeled components (P = .617). Grade 4 or 5 lucency was present in 44% of pegged and 36% of keeled components (P = .743). There were no differences in clinical outcome scores or active mobility outcomes between shoulders with pegged and keeled components at last follow-up. Within the initial cohort, 20% of the keeled shoulders (6 of 30) and 7% of the pegged shoulders (2 of 29) underwent revision surgery (P = .263). Kaplan-Meier analysis showed no significant difference in survival rates between groups (P = .560). CONCLUSION: At an average 7.9-year follow-up, non-ingrowth, all-polyethylene pegged glenoid implants are equivalent to keeled implants with respect to radiolucency, clinical outcomes, and need for revision surgery.

The Constant-Murley (Constant) score, Western Ontario Osteoarthritis of the Shoulder (WOOS) index, American Shoulder and Elbow Surgeons (ASES) score, and Single Assessment Numeric Evaluation (SANE) score are commonly used to assess patient-reported function following shoulder surgery. However, psychometric properties for these tools are mostly unknown for patients with primary glenohumeral arthritis who have undergone anatomic total shoulder arthroplasty (TSA). The purposes of this study were to (1) compare the responsiveness and internal validity between the 4 patient-reported outcomes (PROs) and (2) identify PRO score values associated with patient satisfaction after TSA. A total of 234 primary TSAs were performed for primary glenohumeral osteoarthritis with a 2-year or greater follow-up. The Constant score, WOOS index, ASES score, SANE score, and patient satisfaction were assessed preoperatively and 2 to 5 years postoperatively. Effect sizes, standardized response means, and relative efficiency were calculated to determine responsiveness, and internal validity was determined via the presence of floor and/or ceiling effects. Receiver operator characteristic (ROC) curves were constructed to identify the minimum outcome score that could correctly identify a satisfied patient. At final follow-up, 88% of patients were satisfied. The PROs had large effect sizes and standardized response means (≥0.83). The minimum score that most correctly identified a patient as satisfied was 78 for ASES score, 18 for WOOS index, 73 for Constant score, and 58 for SANE score. However, the ASES score, WOOS index, and SANE score had marked postoperative ceiling effects, whereas the Constant score was the most responsive and internally valid tool. These results suggest that the Constant score should serve as the primary PRO for patients with primary glenohumeral arthritis, whereas the WOOS index, ASES score, and SANE score could be supplementary assessments.
