Surgeons Factors and Trends Associated with the Use of Subacromial Decompression at the Time of Rotator Cuff Repair.

PURPOSE: Subacromial decompression (SAD) has historically been described as an essential part of the surgical treatment of rotator cuff disorders. However, investigations throughout the 21st century have increasingly questioned the need for routine SAD during rotator cuff repair (RCR). Our purpose was to assess for changes in the incidence of SAD performed during RCR over a 12-year period. In addition, we aimed to characterize surgeon and practice factors associated with SAD use. METHODS: Records from two large tertiary referral systems in the United States from 2010 to 2021 were reviewed. All cases of RCR with and without SAD were identified. The outcome of interest was the proportion of SAD performed during RCR across years and by surgeon. Surgeon-specific characteristics included institution, fellowship training, surgical volume, academic practice, and years in practice. Yearly trends were assessed using binomial logistic regression modeling, with a random effect accounting for surgeon-specific variability. RESULTS: During the study period, 37,165 RCR surgeries were performed by 104 surgeons. Of these cases, 71% underwent SAD during RCR. SAD use decreased by 11%. The multivariable model found that surgeons in academic practice, those with lower surgical volume, and those with increasing years in practice were significantly associated with increased odds of performing SAD. Surgeons with fellowship training were significantly more likely to use SAD over time, with the greatest odds of SAD noted for sports medicine surgeons (odds ratio = 3.04). CONCLUSIONS: Although SAD use during RCR appears to be decreasing, multiple surgeon and practice factors (years in practice, fellowship training, volume, and academic practice) are associated with a change in SAD use. CLINICAL RELEVANCE: These data suggest that early-career surgeons entering practice are likely driving the trend of declining SAD. Despite evidence suggesting limited clinical benefits, SAD remains commonly performed; future studies should endeavor to determine factors associated with practice changes among surgeons.

Orthopaedic Research Consortiums: A Review of Scope, Sex and Racial Representation.

Introduction The creation of research groups and consortiums has become more common in all medical and surgical specialities. The purpose of this investigation was to assess and describe collaborative research groups and consortiums within orthopaedic surgery. In addition, we aimed to define the demographics of the research consortium members with particular attention to female and minority members. Methods  Journals with a musculoskeletal/orthopaedic focus and a few medical journals were selected to identify articles published by research groups and consortiums. Articles published from 2020 to 2022 were manually reviewed. Bibliographic information, author information and level of evidence (LOE) were recorded. For identified consortium members, sex and race were defined in a binary manner. Results A total of 92 research consortiums were identified. A list of members was identified for 77 groups (83.7%), totalling 2,260 researchers. The remaining group members were not able to be identified due to the lack of information in the included publications, research group websites or after communicating with the corresponding author for respective articles. Most researchers were male (n=1,748, 77.3%) and white (n=1,694, 75%). Orthopaedic surgeons comprised 1,613 (71.4%) identified researchers. The most common fellowship training for orthopaedic surgeons was paediatrics (n=370, 16.4%), trauma (n=266, 11.8%) and sports medicine (n=229, 10.1%). The consortiums published 261 articles: women were lead (first) authors in 23% and senior (last) authors in 11.1%. Non-white researchers were lead authors in 24.5% (n=64) and senior authors in 17.2% (n=45). The most common level of evidence was level 3, accounting for 45.6% (n=119) of all publications. Level 1 evidence accounted for 12.6% (n=33) of published articles. Discussion Representation of women in orthopaedic research consortiums exceeds their representation in almost every orthopaedic professional society. There is less publicly available data to compare the involvement of under-represented minorities (URMs) in research consortiums to general practice. Further investigations should analyse possible avenues in which gender and racial disparity could be improved within orthopaedic surgery research.

A Comparison of Amyloid Deposition in Endoscopic and Open Carpal Tunnel Release.

PURPOSE: Previous investigations assessing the incidence of amyloidosis detected with biopsy during carpal tunnel release (CTR) have focused on open CTR (OCTR). Prior authors have suggested that biopsy may be more technically challenging during endoscopic carpal tunnel release (ECTR). Our purpose was to compare differences in the incidence of amyloid deposition detected during ECTR versus OCTR. METHODS: We reviewed all primary ECTR and OCTR during which a biopsy for amyloid was obtained between February 2022 and June 2023. All procedures were performed by five upper-extremity surgeons from a single institution. Congo red staining was used to determine the presence of amyloid deposition in either the transverse carpal ligament (TCL) or tenosynovium. All positive cases underwent subtype analysis and protein identification through liquid chromatography-tandem mass spectrometry. Baseline demographics were recorded for each case, and the incidence of positive biopsy was compared between ECTR and OCTR cases. RESULTS: A total of 282 cases were included for analysis (143 ECTR and 139 OCTR). The mean age was 67 years, and 45% of cases were women. Baseline demographics were similar except for a significantly higher incidence of diabetes in OCTR cases (13% vs 33%). Overall, 13% of CTR cases had a positive biopsy. There was a statistically significant difference in the incidence of amyloid deposition detected during biopsy in ECTR cases (3.5%) compared with OCTR cases (23%). CONCLUSIONS: Biopsy performed during ECTR may result in a lower incidence of amyloid detection. Future basic science investigation may be necessary to determine histologic differences between tenosynovium proximal and distal to the leading edge of the TCL. When surgeons plan a biopsy during surgical release of the carpal tunnel, an open approach may be advantageous. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Statistical Literacy in Hand and Upper-Extremity Patients.

Purpose: Statistical literacy is the ability of a patient to apply basic statistical concepts to their health care. Understanding statistics is a critical component of shared decision making. The purpose of this investigation was to define levels of statistical literacy in an upper-extremity (UE) patient population. We aimed to determine if patient demographics would be associated with statistical literacy. Methods: An electronic survey was administered to a consecutive series of UE patients at a single institution. We recorded baseline demographics, Single Assessment Numeric Evaluation scores, the Berlin Numeracy Test (BNT), and General Health Numeracy Test. We also included a surgical risk question, which asked: "Approximately 3% of patients who get carpal tunnel surgery develop an infection. If 100 patients get this surgery, how many would you expect to develop an infection?" A covariate-controlled adjusted odds ratio reflecting the association between each statistical literacy outcome measure and patient characteristics was reported. Results: A total 254 surveys were administered, 148 of which were completed and included. Fifty percent of respondents had a high-school education or less. For the BNT, 78% scored in the bottom quartile, and 52% incorrectly answered all questions. For the General Health Numeracy Test, 34% answered 0 or 1/6 questions correctly. For the surgical risk question, 24% of respondents answered incorrectly. Respondents who had a college or graduate degree had 2.62 times greater odds (95% confidence interval, 1.09-6.32) of achieving a BNT score in a higher quartile than patients who did not have a college or graduate degree. Conclusions: Overall levels of statistical literacy are low for UE patients. Clinical relevance: When engaging in management discussions and shared decision making, UE surgeons should assume low levels of statistical literacy. Consideration of alternative formats, such as frequencies, video-based materials, and pictographs, may be warranted when discussing outcomes and risks of surgical procedures.

Adherence to Complication Reporting for Randomized Controlled Trials Contained in Clinical Practice Guidelines for the Management of Carpal Tunnel Syndrome.

Purpose: Randomized controlled trials (RCTs) are frequently used in creating recommendations contained within clinical practice guidelines (CPGs). However, investigations outside of hand surgery have reported that RCTs within CPGs infrequently report complications and harms-related data. Our purpose was to assess adherence to complication reporting and harms-related outcomes contained in the Consolidated Standards for Reporting (CONSORT) Extension of Harms and Standards for Reporting of Diagnostic Accuracy Studies (STARD) reporting checklists for RCTs within the American Academy of Orthopaedic Surgery (AAOS) CPGs for carpal tunnel syndrome (CTS). Methods: We identified all RCTs within the AAOS CTS CPGs. All therapeutic RCTs and diagnostic studies were included. We used the CONSORT Harms Checklist criteria to assess adherence to the reporting of adverse events for therapeutic RCTs and the STARD criteria to assess the diagnostic accuracy of the articles. We defined adequate compliance as adherence to ≥50% of the checklist items. Results: We identified 82 therapeutic RCTs and 90 diagnostic accuracy articles within the AAOS CTS CPG. For therapeutic RCTs, we found that the average compliance with the published checklists was 19%. For diagnostic studies, the average compliance with checklists was found to be 55%. Eleven therapeutic RCTs (13%) and 60 diagnostic studies (67%) were determined to have adequate compliance for the CONSORT and STARD checklists, respectively. Conclusions: Randomized controlled trials in the AAOS CPGs for CTS have low compliance with the CONSORT Extension for Harms Checklist. Although the overall adherence to the items published in the STARD statement for diagnostic accuracy evaluation remains higher, future efforts should be made to improve the adherence rates to both checklists. Clinical relevance: Improved standardization of complication reporting may aid in comparing outcomes across multiple clinical investigations of upper-extremity procedures.

Analysis of Terminated Hand and Wrist-Related Clinical Trials.

Purpose: While clinical trials provide high-quality evidence guiding medical decision-making, early trial termination can result in both lost time and resources. Our purpose was to investigate the rate of and reasons for clinical trial termination for hand and wrist-related conditions and identify study characteristics associated with early trial termination. Methods: The ClinicalTrials.gov database was queried for all hand and wrist-related clinical trials. All terminated and completed trials were reviewed, with characteristics and reasons for termination recorded. Study characteristics included type, purpose, intervention assessed, enrollment, group allocation, blinding, trial phase, sponsor type, and geographic region. Chi-square test was used to identify associations between trial characteristics and terminated versus completed status. Results: A total of 793 hand and wrist-related clinical trials were identified, with 77 trials (10%) terminated prior to completion. The most common reason for termination was "recruitment/retention difficulty," reported in 37 (48%) terminated trials. In comparing competed versus terminated trials, primary purpose (nonobservational studies), enrollment (<50 patients), and geographic region (North America) were all significantly more likely to be terminated. Terminated trials were more likely to have an intervention type investigating a specific device or drug. Conclusions: Early trial termination for hand and wrist-related conditions is common (10%), with patient recruitment and retention identified as the leading cause of termination. Trials involving potential commercial incentives (those investigating a device or drug) were associated with an increased rate of trial termination. Clinical relevance: An emphasis on patient enrollment during study design may aid in mitigating the most common cause of early clinical trial termination.

The Effect of an Intraoperative Real-Time Counter on Radiation Exposure Events During Operative Treatment of Distal Radius Fractures.

PURPOSE: Occupational radiation exposure can have adverse health consequences for surgeons. The purpose of this study was to determine if utilization of an intraoperative, real-time radiograph counter results in decreased radiation exposure events (REEs) during open reduction and internal fixation (ORIF) of distal radius fractures (DRFs). METHODS: We reviewed all cases of isolated ORIF DRFs performed at a single center from January 2021 to February 2023. All cases performed on or after January 1, 2022 used an intraoperative radiograph counter, referred to as a "shot-clock" (SC) group. Cases prior to this date were performed without a SC and served as a control group (NoSC group). Baseline demographics, fracture, and surgical characteristics were recorded. Final intraoperative radiographs were reviewed to record reduction parameters (radial inclination, volar tilt, and ulnar variance). REEs, fluoroscopy exposure times, and total radiation doses milligray (mGy) were compared between groups. RESULTS: A total of 160 ORIF DRF cases were included in the NoSC group, and 135 were included in the SC group. The NoSC group had significantly more extra-articular fractures compared with the SC group. Reduction parameters after ORIF were similar between groups. The mean number of REEs decreased by 48% in the SC group. Cases performed with the SC group had significantly lower total radiation doses (0.8 vs 0.5 mGy) and radiation exposure times (41.9 vs 24.2 seconds). Mean operative times also decreased for the SC group (70 minutes) compared with that for the NoSC group (81 minutes). CONCLUSIONS: A real-time intraoperative radiograph counter was associated with decreased REEs, exposure times, and total radiation doses during ORIF DRFs. Cases performed with a SC had significantly shorter operative times without compromising reduction quality. Using an intraoperative SC counter during cases requiring fluoroscopy may aid in decreasing radiation exposure, which serves as an occupational hazard for hand and upper-extremity surgeons. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Sensitivity and Specificity of Examination Maneuvers for Carpal Tunnel Syndrome: A Meta-Analysis.

Our purpose was to assess the diagnostic validity (sensitivity (Sn) and specificity (Sp)) of physical examination maneuvers for carpal tunnel syndrome (CTS). This meta-analysis utilized the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Studies assessing exam maneuvers (including components of the CTS-6) for CTS were identified in MEDLINE (Medical Literature Analysis and Retrieval System Online) and Embase (Excerpta Medica Database) databases. Assessed maneuvers assessed included: Phalen's test, Tinel's sign, Durkan test, scratch-collapse test, Semmes-Weinstein monofilament (SWM), and static 2-point discrimination (2PD) test. Data extracted included: article name, total number of subjects/hands, type of exam, and exam Sn/Sp. Forest plots were presented to display the estimated Sn/Sp and boxplots were used to demonstrate the locality, spread, and skewness of the Sn/Sp through the quartiles. After screening 570 articles, 67 articles involving 8924 hands were included. Forty-eight articles assessed Phalen's test, 45 assessed Tinel's sign, 21 assessed the Durkan test, seven assessed the scratch-collapse test, 11 assessed SWM, and six assessed the static 2PD test. Phalen's test demonstrated the greatest median Sn (0.70, (Q1, Q3): (0.51, 0.85)), followed by the Durkan test (0.67, (Q1, Q3): (0.46, 0.82)). 2PD demonstrated the highest median Sp (0.90, (Q1, Q3): (0.88, 0.90)), followed by SWM (0.85, (Q1, Q3): (0.51, 0.89)). There is considerable variability with respect to the validity of physical exam tests used in the diagnosis of CTS. Upper-extremity surgeons should be aware of inherent limitations for individual exam maneuvers. In the absence of a uniformly accepted diagnostic gold standard, a combination of exams, along with pertinent patient history, should guide the diagnosis of CTS.

An Analysis of Gender Diversity in Hand and Upper Extremity Surgery Webinars.

PURPOSE: Some female upper extremity (UE) surgeons face unique barriers to participation at in-person academic and professional society meetings due to disparate childcare and household duties relative to male surgeons. Webinars may alleviate some of this travel burden and allow for more balanced participation. Our purpose was to evaluate gender diversity within academic webinars with a focus on UE surgery. METHODS: We queried webinars conducted by the following professional societies: American Academy of Orthopaedic Surgeons, American Society for Surgery of the Hand (ASSH), American Association for Hand Surgery, and American Shoulder and Elbow Surgeons societies. Webinars with an UE focus produced between January 2020 and June 2022 were included. Demographic characteristics, including sex and race, were recorded for webinar speakers and moderators. RESULTS: A total of 175 UE webinars were identified, with 173 of 175 (99%) having functioning video links. The 173 webinars had 706 speakers and 173 (25%) were women. Female representation in professional society webinars exceeded their overall participation in their sponsoring organizations. Although women comprise 6% and 15% of the overall American Academy of Orthopaedic Surgeons and ASSH membership, respectively, they accounted for 26% of American Academy of Orthopaedic Surgeons webinar speakers and 19% of ASSH webinar speakers. CONCLUSIONS: Between 2020 and 2022, women comprised 25% of speakers for professional society academic webinars with a focus on UE surgery, which exceeds the proportion of women in the individual sponsoring professional societies. CLINICAL RELEVANCE: Online webinars may mitigate some of the barriers that female UE surgeons face with respect to professional development and academic advancement. Although female participation in UE webinars often exceeded the current rates of female members in the individual professional societies, women remain underrepresented in UE surgery, relative to the percentage of female medical students.

Publicly Disclosed Pricing for Common Upper-Extremity Procedures: An Analysis of Hospital Chargemasters.

BACKGROUND: American hospitals are required to provide price transparency data (known as a chargemaster) for medical services, which is intended to allow consumers to accurately estimate the cost of medical services. Our purpose was to identify hospital compliance in publishing chargemaster documents and to assess the price information published for common upper-extremity services and procedures. METHODS: We performed a cross-sectional analysis of publicly available chargemaster data from 122 hospitals, which included the top-20-ranked Honor Roll hospitals from US News and World Report and 2 top-ranked hospitals from each state. Chargemaster files were accessed for each hospital, and price information was recorded for 10 common upper-extremity procedures including radiographs, injections, and surgeries. Mean procedural prices were compared between academic and nonacademic hospitals. RESULTS: Chargemaster files were able to be accessed for 107 (88%) of 122 institutions. Price estimates for imaging studies were more frequently reported (73%) than those of procedures (23%-41%). With 50 hospitals reporting a price estimate, carpal tunnel injection was the most frequently reported procedure, whereas trigger finger release was the least frequently reported (41% and 23%, respectively). Wide price ranges were noted, with mean charges for a total shoulder arthroplasty listed as US $51 723 (range, US $247-US $364 024). Mean prices between academic and nonacademic hospital systems were similar. CONCLUSIONS: While most (88%) of the included hospitals have been compliant with publishing their price transparency files, price estimates for common upper-extremity procedures and imaging studies are inconsistently reported and, when present, demonstrate high levels of price variability between and within hospital systems.

Race and Ethnicity Reporting in Randomized Controlled Trials Published in Upper-Extremity Journals.

PURPOSE: Hand surgery remains one of the least racially and ethnically diverse subspecialties in all of medicine, and minority patients demonstrate overall worse health care outcomes compared with White patients. Our purpose was to determine the frequency of race and ethnicity reporting in randomized controlled trials (RCTs) published in journals with an upper-extremity (UE) focus. METHODS: A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines by searching EMBASE and MEDLINE for RCTs contained in peer-reviewed journals with an UE focus. All articles from 2000 to 2021 were included. Information such as article sample size, center type, funding, and location was recorded. We assessed each article to determine whether demographic information, including race and ethnicity, was reported for study participants. RESULTS: A total of 481 RCTs in 9 UE journals were included. For UE RCTs, 96% of studies reported age, 90% reported sex, and 5% reported either race or ethnicity. Demographic information about economic status, insurance status, mental health, educational level, and marital status were each reported in <10% of RCTs. Racial representation was highest for White participants (80%) and lowest among American Indian participants. Of studies conducted within the United States, all racial groups except for White patients were underrepresented compared with census data. CONCLUSIONS: Demographic data related to race and ethnicity for patients involved in UE RCTs are infrequently reported. When reported, the racial demographics of UE RCT patients do not match the demographics of the patients in United States. Black patients remain underrepresented in RCTs. CLINICAL RELEVANCE: Academic journals mandating the reporting of demographic data related to race may aid in improved reporting and allow for subsequent aggregation within systematic reviews to assess outcomes for racial minorities.

Intraoperative Conversion From Endoscopic to Open Carpal Tunnel Release: A Systematic Review and Case Series.

PURPOSE: The purpose of this study was to assess the incidence, outcomes, and complications associated with conversion from endoscopic carpal tunnel release (ECTR) to open carpal tunnel release (OCTR). METHODS: A retrospective case review of all patients who underwent ECTR over 4 years by 2 fellowship-trained hand surgeons at a single academic center was performed. We recorded outcomes and the reason for conversion in patients who underwent conversion to an OCTR. Baseline demographics and surgical complications were compared between the 2 groups. A systematic review was performed to define the incidence and reasons for conversion from ECTR to OCTR. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we included clinical studies of ECTR from 2000 to 2021. RESULTS: In the retrospective series, 9 of 892 (1.02%) ECTR cases underwent conversion to an OCTR at the time of the index procedure. One of 9 converted cases had transient neurapraxia involving the recurrent motor branch after surgery compared with 0 cases in the group that underwent ECTR without conversion. Improvements in the visual analog scale for pain and QuickDASH were noted at a mean of 46 weeks after surgery in the group that underwent conversion to OCTR. The systematic review identified an incidence of conversion of 0.62%. The most common reasons for conversion to OCTR in the case series and systematic review were poor visualization due to hypertrophic tenosynovium and aberrant nerve anatomy. CONCLUSIONS: The overall incidence of intraoperative conversion from ECTR to OCTR during the index procedure was 1.02%, with the most common reasons for conversion being poor visualization due to hypertrophic tenosynovium and aberrant nerve anatomy. Patients who undergo conversion from ECTR to OCTR demonstrate improvements in pain and disability, similar to patients who undergo ECTR without conversion. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

The Impact of Smoking on Delayed Osseous Union After Arthrodesis Procedures in the Hand and Wrist.

PURPOSE: The purpose of this study was to evaluate the relationship between smoking and delayed radiographic union after hand and wrist arthrodesis procedures. We hypothesized that smoking would be associated with a higher rate of delayed union. METHODS: All cases of hand or wrist arthrodesis procedures in patients aged ≥18 years from 2006 to 2020 were identified. Cases were included if they had >90 days of radiographic follow-up or evidence of union before 90 days. Baseline demographics were recorded for each case including smoking status at the time of surgery. Complications were recorded and all postoperative radiographs were reviewed to assess for evidence of delayed union (defined as lack of osseous union by 90 days after surgery). We compared active smokers and nonsmokers and performed a logistic regression analysis to estimate the odds of experiencing a delayed radiographic union. RESULTS: A total of 309 arthrodesis cases were included and 24% were active smokers. Overall, radiographic evidence of a delayed union was found in 17% of cases. Smokers were significantly more likely to have a delayed union compared with nonsmokers (27% vs 14%). Results of the adjusted logistic regression analysis demonstrated that there was a significantly increased odds of experiencing a delayed union for patients who were active smokers compared with nonsmokers (odds ratio, 2.20; 95% confidence interval, 1.09-4.43). In addition, the rate of symptomatic nonunion requiring reoperation was higher in smokers (15%) compared with nonsmokers (6%). CONCLUSIONS: Smoking was associated with increased odds of delayed radiographic union in patients undergoing hand and wrist arthrodesis procedures. Patients should be counseled appropriately on the risks of smoking on bone healing and encouraged to abstain from nicotine use in the perioperative period. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Lateral Ulnar Collateral Ligament Repair With Suture-Tape Augmentation for Traumatic Elbow Instability.

PURPOSE: Ligament repair with suture-tape augmentation has been used in the operative treatment of joint instability and may have advantages with respect to early motion and stability. The purpose of this investigation was to describe the clinical results of traumatic elbow instability treated with lateral ulnar collateral ligament repair with suture-tape augmentation. METHODS: All cases of acute and chronic elbow instability treated surgically between 2018 and 2020 were included if they underwent ligament repair with suture-tape augmentation of the lateral ulnar collateral ligament as part of the procedure. Cases with <6 months of follow-up were excluded. A manual chart review was performed to record patient demographics as well as injury and surgery characteristics. Radiographic outcomes, range of motion, and patient-reported outcome measures, including the visual analog pain scale and Disabilities of the Arm, Shoulder, and Hand, were recorded. Range of motion measurements were recorded at the end of the clinical follow-up, as were surgical complications. RESULTS: Eighteen cases were included with a mean follow-up of 20 months. Five (28%) cases involved a high-energy mechanism, and 11 (62%) cases involved terrible triad fracture dislocations. The mean Disabilities of the Arm, Shoulder, and Hand questionnaire and visual analog pain scale scores were 17 and 2, respectively. The mean flexion-extension arc was 124°, and 2 (11%) cases had <100° flexion-extension arc. There were 2 (11%) postoperative complications, and both cases had postoperative instability requiring reoperation. We observed no cases of capitellar erosion from the suture-tape material. CONCLUSIONS: For complex elbow instability, ligament repair with suture-tape augmentation of the lateral ulnar collateral ligament results in acceptable functional outcomes and a reoperation rate comparable with other joint stabilization procedures. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Arthroscopic Removal of the Polyethylene Glenoid Component After Total Shoulder Arthroplasty: A Systematic Review.

Purpose: To identify prior studies of arthroscopic glenoid component removal after total shoulder arthroplasty (TSA) and understand indications, techniques and patient outcomes. Methods: A search of the English language literature on arthroscopic removal of the glenoid component (ARGC) after TSA published between 2005 and 2021 was performed from MEDLINE and EMBASE databases. Articles with ARGC after TSA were identified and we recorded article characteristics as well as patient demographics and outcomes contained within the studies. Results: A total of six publications (two case reports and four retrospective case series) detailing the outcome of ARGC performed on twenty-five shoulders were identified. The average time from index procedure to glenoid removal was 117 months and mean age at time of ARGC was 75 years. Although patient reported outcomes measures (PROMs) varied in type and reporting style, all articles reported improvements in PROMs. Twenty patients in this systematic review were evaluated for post-operative complications and the complication rate was found to be 15% (n = 3). There were 2 cases (18%) of superior migration of the humeral head relative to the glenoid and no reported cases of anterior or posterior humeral head subluxation. Two of 25 patients (8%) underwent subsequent open revision procedures. Conclusions: The limited number of publications in this systematic review demonstrates that ARGC after TSA can result in improvements in both pain and PROMs. This less-invasive arthroscopic technique may be an alternative to open revision for lower demand patients; however, future prospective, comparative studies are necessary to better define indications.

The Impact of Cement Mantle Characteristics on Early Loosening in Primary Total Elbow Arthroplasty.

PURPOSE: To assess the association between cement mantle characteristics and early radiographic loosening in total elbow arthroplasty (TEA). We aimed to determine whether shorter mantle heights (<20 mm) were associated with loosening. METHODS: We reviewed primary TEAs from a single healthcare system from 2006 to 2020. TEAs complicated by infection or performed for oncologic conditions were excluded. Initial postoperative radiographs were reviewed to determine cement mantle and component characteristics (mantle quality, mantle height, and component angulation). One-year postoperative radiographs were reviewed to assess for implant loosening, and we compared demographics and radiographic criteria for cases with and without early loosening. We noted whether cases underwent subsequent revision for aseptic osteolysis. RESULTS: A total of 54 TEA cases were included. Forty percent of ulnar and 24% of humeral mantles were classified as short (between 1 and 19 mm). According to the Morrey classification, 6 (11%) cases had an inadequate cement mantle Twenty-four (45%) cases had radiographic evidence of loosening at 1 year. Of the cases with early loosening, 6 (25%) had initial inadequate mantle quality. There were no inadequate mantles in the group without loosening. There were no statistically significant differences in mantle heights for cases with and without loosening at 1 year after surgery. Eight (33%) cases underwent revision in the group with early loosening compared with 1 (3%) case without early loosening. CONCLUSIONS: Inadequate cement mantle quality was associated with an increased risk of early aseptic loosening after primary TEA. Cement mantles that extended past the tip of the prosthesis were not associated with loosening. Considering the potential need for future revision and morbidity of cement removal, surgeons should focus on mantle quality and carefully plan mantle height because shorter heights may not be associated with early implant failure. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Pathologic Periprosthetic Fracture After Radial Head Arthroplasty: A Report of 2 Cases.

CASE: We present 2 cases of pathologic periprosthetic radius fractures in the setting of osteolysis after radial head arthroplasty (RHA) with a porous-coated, press-fit implant. Both patients were managed with implant removal without subsequent instability. Although radiographic lucencies are common after RHA, progressive bone resorption can result in subsequent periprosthetic fractures. CONCLUSION: Although osteolysis after RHA is not always clinically significant, these cases demonstrate that this radiographic finding may indicate adverse clinical consequences. Surgeons who perform implant excision should be ready to address further instability as needed. LEVEL OF EVIDENCE: Level V, case reports.

Learning Curve Associated With Operative Treatment of Terrible Triad Elbow Fracture Dislocations.

PURPOSE:  To assess the outcomes of operatively treated terrible triad (TT) elbow injuries for a single surgeon at the start of clinical practice. We aimed to define postoperative patient reported outcome measures (PROMs), range of motion (ROM), and complications during the period immediately following fellowship training, in order to describe the learning process for surgical treatment of TT.  Methods: All operatively treated TTs from 2017 to 2020 were included. All cases were performed by a single, fellowship-trained upper-extremity surgeon and represented a consecutive series at the start of clinical practice. Baseline demographics, injury characteristics, and surgical details were recorded for each case. PROMs [QuickDisability of arm, shoulder, and hand (DASH) and (visual analog scale) pain scale], ROM, and complications were recorded at the time of final follow-up. A perioperative glucocorticoid protocol was used in all cases without diabetes. RESULTS:  There was a total of 21 included TT cases with a mean follow-up of 20 months. The operative time averaged 89 min for the first 10 cases and 83 min for the subsequent 11 cases. The mean QuickDASH and VAS pain score at final follow-up were 19 and 2.3, respectively. The mean flexion-extension arc was 122° and two cases (9%) had < 100° arc of motion. The mean pronation-supination arc was 145°. Three cases (14%) had a postoperative complication, all of which underwent reoperation. Of the 21 included cases, these reoperations represented cases #1, #14, and #17 respectively.  Conclusions: Upper-extremity surgeons at the start of clinical practice may be able to achieve outcomes similar to more experienced surgeons for operatively treated TT elbow fracture dislocations. There does not appear to be a substantial "learning curve" after fellowship training with respect to PROMs, complication rates, or operative time associated with surgical treatment of TT elbow injuries.

A Comparison of Acute Versus Chronic Thumb Ulnar Collateral Ligament Surgery Using Primary Suture Anchor Repair and Local Soft Tissue Advancement.

Purpose: To assess patient satisfaction and functional outcomes of primary suture anchor repair with local soft tissue advancement for both acute and chronic thumb ulnar collateral ligament (UCL) injuries. Methods: We retrospectively reviewed patient charts who had undergone operative UCL repair between 2006 and 2013. Patients who had more than 8 weeks between the time of injury and surgery were classified as having chronic injuries. In both acute and chronic cases, a primary suture anchor repair of the ligament was performed with local soft tissue advancement. For each patient, baseline demographics, operative complications, and associated injuries were recorded along with visual analog scale pain scores; Quick Disabilities of the Arm, Shoulder, and Hand scores; and their return to work or sport status. Comparisons of outcomes and complications were made between the groups (acute vs chronic injuries). Results: Among the 36 patients who met our inclusion criteria, both the acute (n = 19) and chronic (n = 17) groups were similar with regards to major or minor comorbidities, visual analog scale scores; Quick Disabilities of the Arm, Shoulder, and Hand scores; return to work or sport status; or patient satisfaction. Conclusions: Patients with both acute and chronic thumb UCL injuries have similarly acceptable functional outcomes, postoperative pain, and satisfaction. Primary suture anchor repair without ligament reconstruction appears to be a safe and effective treatment option for patients' thumb UCL injuries, even in the chronic setting.

Analysis of the Most Frequently Cited Articles in Hand and Wrist Surgery: A Modern Reading List.

The aim of this investigation was to analyze the 50 most frequently cited articles on hand and wrist surgery of all time and those published during the 21st century. We aimed to evaluate the article, author, and journal characteristics for these publications in order to create a modern reading list of impactful upper-extremity articles. A search of the Journal Citation Reports 2022 edition to identify journals containing possible hand or wrist-related articles was performed. Related journals were identified and then searched on the Web of Science database to identify hand and wrist articles. The top 50 most cited articles overall and the top 50 most cited articles from 2000-2021 were identified and indexed. Several bibliometric parameters, such as study type, study topic, study design, level of evidence, citation count, citation density, the institution of the lead author, the gender of lead and senior authors, and country were analyzed. For the most cited articles of all time, the number of citations ranged from 224 to 1109 with a mean of 368 citations and 15.0 citation density. Citations for the top 50 articles from 2000-2021 ranged from 153 to 950 with a mean of 233 citations and 14.5 citation density. For both groups, the most common level of evidence was level IV (33% and 27%). No correlation between journal impact factor and citation count or citation density was found. In both groups, "fracture" was the most common topic and papers were predominantly written by male authors. Frequently cited publications on hand and wrist surgery are often clinical papers that contain low levels of evidence and tend to focus on topics related to fracture care. Female authors remain underrepresented.
