Abstract
BACKGROUND Improper sequencing order of maximal joint and segment velocities has been identified as an important predictor for both throwing arm kinetics and ball velocity. PURPOSE To investigate the intrapitcher variation of maximal segment velocities and the relationship to throwing arm kinetics and ball velocity in high school (HS) and professional (PRO) pitchers. STUDY DESIGN Descriptive laboratory study. METHODS HS (n = 59) and PRO (n = 338) pitchers, instructed to throw 8 to 12 fastball pitches, were evaluated with 3-dimensional motion capture (480 Hz). Maximal joint and segment velocities were calculated for each pitch, and the standard deviation of the maxima was calculated per pitcher. These standard deviations were used to classify pitchers as "low variance" or "high variance" for each segmental velocity subgroup, "overall low variance" or "overall high variance" based on cumulative segment velocity variation, or "population," with any pitcher eligible to be included in multiple subcategories. Maximal velocities and throwing arm kinetics were compared among the various subgroups. RESULTS The HS low-variance shoulder internal rotation velocity subgroup (4949 ± 642 deg/s) had significantly lower maximal shoulder internal rotation velocity compared with HS population (5774 ± 1057 deg/s) (P < .001); similar findings were observed for PROs (5269 ± 835 vs 5824 ± 1076 deg/s; P < .001), as well as lower shoulder superior force compared with the PRO population (14.8% ± 8.8% vs 17.8% ± 8.8% body weight; P = .001). The PRO low-variance lead knee extension velocity subgroup had significantly lower maximal lead knee extension velocity (216 ± 135 vs 258 ± 125 deg/s; P = .001) and shoulder distractive force (111.5% ± 14.4% vs 115.6% ± 15.9% body weight; P = .003) compared with the PRO population. The PRO overall low-variance subgroup had significantly lower shoulder distractive force (111.8% ± 14.1% vs 119.6% ± 15.5% body weight; P = .008) and elbow anterior force (40.6% ± 5.0% vs 43.6% ± 6.2% body weight; P = .008) compared with the PRO overall high-variance subgroup. CONCLUSION HS and PRO pitchers with low variance for joint and segment velocities achieved significantly lower maximal velocities in the subgroup of interest, while preserving ball velocity. PRO pitchers with overall low variance among multiple maximal joint and segment velocities demonstrated decreased shoulder distractive and elbow anterior force. CLINICAL RELEVANCE PRO pitchers with low intrapitch variation in maximal joint and segment velocities may be viewed as kinetically conservative throwers. These pitchers with similarly maintained mechanics between pitches may have an increasingly regimented form that preserves kinetic forces about the throwing arm. The opposite may be true for PRO pitchers with increased variability in segmental velocities during their pitching motion, as they showed increased throwing arm kinetics including shoulder distractive and elbow anterior force compared with the overall low-variance group, theoretically increasing their risk of injury.

Predicting Academic Productivity Among American Shoulder and Elbow Surgeons (ASES) Fellowship Faculty from Publications Acquired Before and During Surgical Training. J Shoulder Elbow Surg 2024:S1058-2746(24)00226-X. [PMID: 38582253 DOI: 10.1016/j.jse.2024.02.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Revised: 02/04/2024] [Accepted: 02/12/2024] [Indexed: 04/08/2024]
Abstract
BACKGROUND Orthopedic residency and fellowship applicants with a strong research record are highly valued for their potential in continuing academic excellence. Despite this, the association between research productivity during training and future academic productivity as an attending orthopedic surgeon is not well-established. We assess the effects of research output during different periods of surgical training as well as residency location on long-term academic productivity as an attending shoulder and elbow surgeon. METHODS A search of the 2022-2023 American Shoulder and Elbow Surgeons (ASES) Fellowship Directory was conducted to identify a list of orthopedic shoulder and elbow fellowship faculty members. Each surgeon's residency, fellowship and current institution of practice were determined and stratified by geographic location. Total publication counts acquired before residency, during residency, during fellowship, and after fellowship were collected for each faculty member. Attending publication rates and H-indices were calculated. A multivariate linear regression model was created, and significance was set at a P-value < 0.05. RESULTS A total of 149 shoulder and elbow fellowship faculty members representing 34 fellowship programs were identified. The average number of total publications per surgeon was 88.8 ± 102. The average attending publication rate was 5.29 ± 6.89 publications per year. The average H-index for included surgeons was 27.8 ± 24.4. The number of publications acquired before residency (β = 0.293; P < 0.001), during residency (β = 0.110; P = 0.025) and during fellowship (β = 0.593; P < 0.001) were significantly associated with an increased attending publication rate, but no association was observed with the H-index [before residency (β = -0.221; P = 0.574), during residency (β = 0.045; P = 0.866), during fellowship (β = 0.198; P = 0.678)]. There were no significant differences in total publication count (P = 0.397), attending publication rate (P = 0.237), or H-index (P = 0.364) based on location of residency training. DISCUSSION Research output before and during surgical training is predictive of continued academic productivity as a shoulder and elbow surgeon. In particular, greater productivity during surgical fellowship was most predictive of academic output as an attending. While long-term academic productivity does not seem to be influenced by the geographic location of residency training, attending surgeons practicing in the Midwest had significantly greater total publication counts and H-indices but similar annual publication rates.

Pitch-classifier model for professional pitchers utilizing 3D motion capture and machine learning algorithms. J Orthop 2024; 49:140-147. [PMID: 38682007 PMCID: PMC11043625 DOI: 10.1016/j.jor.2023.12.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 12/13/2023] [Accepted: 12/14/2023] [Indexed: 05/01/2024] Open
Abstract
Introduction A pitcher's ability to achieve pitch location precision after a complex series of motions is of paramount importance. Kinematics have been used in analyzing performance benefits like ball velocity, as well as injury risk profile; however, prior utilization of such data for pitch location metrics is limited. Objective To develop a pitch classifier model utilizing machine learning algorithms to explore the potential relationships between kinematic variables and a pitcher's ability to throw a strike or ball. Methods This was a descriptive laboratory study involving professional baseball pitchers (n = 318) performing pitching tests under the setting of 3D motion-capture (480 Hz). Main outcome measures included accuracy, sensitivity, specificity, F1 score, positive predictive value (PPV), and negative predictive value (NPV) of the random forest model. Results The optimized random forest model resulted in an accuracy of 70.0 %, sensitivity of 70.3 %, specificity of 48.5 %, F1 equal to 80.6 %, PPV of 94.3 %, and a NPV of 11.6 %. Classification accuracy for predicting strikes and balls achieved an area under the curve of 0.67. Kinematics that derived the highest % increase in mean square error included: trunk flexion excursion(4.06 %), pelvis obliquity at foot contact(4.03 %), and trunk rotation at hand separation(3.94 %). Pitchers who threw strikes had significantly less trunk rotation at hand separation(p = 0.004) and less trunk flexion at ball release(p = 0.003) compared to balls. The positive predictive value for determining a strike was within an acceptable range, while the negative predictive value suggests if a pitch was determined as a ball, the model was not adequate in its prediction. Conclusions Kinematic measures of pelvis and trunk were crucial determinants for the pitch classifier sequence, suggesting pitcher kinematics at the proximal body segments may be useful in determining final pitch location.

Abstract
Background Previous reports found that 40% of randomized controlled trials (RCTs) published in The Journal of Bone & Joint Surgery (JBJS) from 1988 to 2000 and 47% of those published from 2001 to 2013 were of high quality. The purpose of this study was to assess the quality of RCTs published from 2014 to 2022 in JBJS and to compare these findings with those of prior analyses in order to identify trends over time and areas for continued improvement. Methods PubMed was searched for the term "randomized controlled trial" to identify studies published in JBJS from 2014 to 2022. Each included RCT was evaluated with use of the Detsky score and a risk-of-bias assessment modified from the Cochrane tool. These evaluations were then compared with previous evaluations of RCTs from the 1988 to 2000 and 2001 to 2013 periods with use of independent-sample t tests. A transformed Detsky score of >75% and a modified risk-of-bias score of ≥8 were defined as being indicative of high quality. Results A total of 218 RCTs were published in JBJS from 2014 to 2022. An a priori sample size was calculated in 183 studies (83.9%). A total of 152 (83.1%) of the 183 studies enrolled the calculated number of patients, of which 126 (82.9%) maintained an adequate number at the time of final follow-up. Most RCTs were conducted at a single center (146 of 218; 67%), evaluated a surgical intervention (162 of 218; 74%), and reported positive results (142 of 218; 65%). The mean transformed Detsky score was 85% ± 10% (95% confidence interval, 83.7% to 86.3%), with 82% of trials (179 of 218) scored as high quality. The mean transformed Detsky score from 2014 to 2022 was higher than that from 1988 to 2000 and that from 2001 to 2013 (85% versus 76% and 68%, respectively; p < 0.001). The mean modified risk-of-bias score was 7 ± 1, with 42% of trials (92 of 218) scored as high quality. RCTs published from 2014 to 2022 had a higher mean modified risk-of-bias score than those published from 2001 to 2013 (7 ± 1 versus 6 ± 1; p < 0.001). Compared with the 2001 to 2013 and 2014 to 2022 periods, the 1988 to 2000 period had a greater proportion of trials that reported positive results (51% and 65% versus 82%, respectively; p < 0.001) and that included data from multiple centers (31% and 33% versus 67%; p < 0.001). Conclusions The quality of RCTs published in JBJS from 2014 to 2022 has improved from that reported previously, as demonstrated by the increases in the modified risk-of-bias score and transformed Detsky score from prior periods. This may be the result of journal policies such as the requirements of CONSORT adherence and prospective trial registration. Investigators should focus on improving the clarity of reporting, limiting attrition bias, and making efforts to blind support staff in order to increase the quality of future RCTs. Clinical Relevance Improving the quality of RCTs is crucial given their potential to influence current clinical practice.

Abstract
Background The purpose of this study is to characterize National Institutes of Health (NIH) funding for rotator cuff research and evaluate the impact of orthopedic surgeons on this portfolio. Methods The NIH's Research Portfolio Online Reporting Tools Expenditures and Results database was queried for "rotator cuff repair" or "rotator cuff tear" from the 2011 to 2021 fiscal years. Compound annual growth rates were calculated and grants were categorized by basic, clinical, or translational research. Funding totals were compared by Principal Investigator (PI) and grant characteristics. Results A total of 52 grants were awarded to 38 PIs between 2011 and 2021, totaling $40,156,859. Annual NIH funding for rotator cuff tear and rotator cuff repair increased by a Compound annual growth rate of 11.0% from 2011 to 2021, compared to 3.4% for the total NIH budget. Orthopedic surgeon-scientists received $9,208,212 (22.9%), most commonly through R01 (80.5%) and K08 (7.1%) mechanisms. No significant difference in funding was found by PI sex (P = .332), degree (P = .460), academic rank (P = .118), or researcher type (P = .227). Professors had a higher h-index than associate and assistant professors (P = .001). Orthopedic surgeon-scientists had a higher h-index (mean 36.3 ± 9.4) compared to clinician-scientists (mean 8.0 ± 1.4) and research-scientists (35.5 ± 40.7) (P = .044). Clinical topics receiving the highest funding were rehabilitation (23.9%), diagnosis, (22.3%) and surgical technique (14.8%). Orthopedic surgeon-scientists acquired funding for diagnosis (57.1%), rehabilitation (17.0%), and surgical technique (14.5%). Discussion While NIH funding for rotator cuff research is growing, orthopedic surgeon representation is low. Future studies should evaluate barriers to obtaining funding for orthopedic surgeon-scientists.

Long-Term Patient Outcomes for Treatment of Difficult Osteochondral Lesions of the Talus with Particulated Juvenile Allograft Cartilage Implantation ± Calcaneal Autograft: A Cohort Study. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024; 34:561-568. [PMID: 37650974 DOI: 10.1007/s00590-023-03642-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/12/2023] [Accepted: 07/03/2023] [Indexed: 09/01/2023]
Abstract
BACKGROUND Osteochondral lesions of the talus (OCLT) are common injuries that can be difficult to treat. To date, long-term patient reported outcome measures (PROMs) of patients with particulated juvenile allograft cartilage implantation with or without calcaneal autograft have not been compared. METHODS Thirteen patients with difficult to treat OCLTs underwent arthroscopic-assisted implantation of particulated juvenile allograft cartilage (DeNovo NT®) with or without autogenous calcaneal bone grafting by a single surgeon. Calcaneal bone graft use was determined by lesion size > 150 mm2 and/or deeper than 5 mm. Patients were evaluated using physical examination, patient interviews, and PROMs. RESULTS When comparing patients in regards to calcaneal bone graft implantation, no difference in age, BMI, pre-operative PROMs, or follow-up was noted, however, calcaneal bone graft patients did have a significantly larger lesion size (188.5 ± 50.9 vs. 118.7 ± 29.4 mm2 respectively; p value = 0.027). VAS and FAAM ADL scores during final follow-up improvement did not significantly differ between cohorts. The FAAM Sports score improved significantly more for the DeNovo alone group compared to the bone graft cohort (p value = 0.032). The AOFAS score improvement did not differ between cohorts (p value = 0.944), however, the SF-36 PCS improved significantly more for the DeNovo alone group compared to the bone graft cohort (p value = 0.038). No intraoperative/perioperative complications were observed with calcaneal bone grafting. CONCLUSION While patients followed over the course of ~ 8 years after implantation of particulated juvenile allograft cartilage (DeNovo NT®) with/without autogenous calcaneal bone graft had positive post-operative PROMs, patients without calcaneal bone graft had significantly greater improvement in functional outcome scores. Whether these differences are due to graft incorporation or larger lesion size is unclear. LEVEL OF EVIDENCE III, retrospective cohort study.

Poor evidence is used to support commercial payers' coverage policies for shoulder arthroplasty. J Shoulder Elbow Surg 2023; 32:2222-2231. [PMID: 37247779 DOI: 10.1016/j.jse.2023.04.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Revised: 04/02/2023] [Accepted: 04/12/2023] [Indexed: 05/31/2023]
Abstract
BACKGROUND The incidence of shoulder arthroplasty has continued to increase over the past decade. In response, commercial payers have implemented strategies to control the medical requirement of these surgeries in attempt to contain the growing costs. For example, most payers require a prolonged trial of conservative management prior to shoulder arthroplasty for patients who may otherwise be surgical candidates. However, little is known regarding the evidence used to support these indications. The purpose of this study was to analyze the references used by commercial payers to substantiate their coverage policies for shoulder arthroplasty. METHODS Ten of the leading commercial payers for total shoulder arthroplasty were identified. Publicly available coverage policies were searched on the internet or requested directly from the payer via email or telephone. Cited references were reviewed independently by two authors for type of document, level of evidence, and mention of the efficacy of conservative management. RESULTS A total of 5 coverage policies were obtained with 118 references. The most common reference type was primary journal article (n = 70; 59.3%) followed by review or expert opinion articles (n = 35; 29.7%). Most references were of level IV evidence (n = 60; 52.2%), with only 6 (5.2%) of level I or II evidence. Only 4 (3.5%) references mentioned the efficacy of conservative management in patients who may be candidates for shoulder arthroplasty. CONCLUSION The majority of references used to substantiate the coverage policies for shoulder arthroplasty among major commercial payers within the United States are of low scientific evidence and fail to demonstrate the success of required nonoperative intervention strategies. Our study underscores the need for high-quality, comparative trials that evaluate the outcomes of conservative management vs. shoulder arthroplasty in end-stage glenohumeral osteoarthritis patients in order to determine the most cost-effective treatment algorithm.

Abstract
BACKGROUND Major League Baseball (MLB) players are at risk for metacarpal fractures; however, little is known regarding the impact of these injuries on future performance. The purpose of this study was to determine whether MLB players who sustain metacarpal fractures demonstrate decreased performance on return to competition in comparison to the performance of control-matched peers. METHODS Data for MLB position players with metacarpal fractures incurred over 17 seasons were obtained from injury reports, press releases, and player profiles. Age, position, career experience, body mass index (BMI), injury mechanism, handedness, and treatment were recorded. Individual season statistics for the 2 seasons immediately before injury and the 2 seasons after injury were obtained. Controls matched by player position, age, BMI, career experience, and performance statistics were identified. A performance comparison of the cohorts was performed. RESULTS Overall, 24 players met inclusion criteria. Eleven players with metacarpal fractures were treated with surgery (46%) and 13 (54%) were treated nonoperatively. Players treated nonoperatively missed significantly fewer games following injury compared with those treated operatively (35.5 vs 52.6 games, P = .04). There was no significant difference in postinjury performance when compared with preinjury performance among the fracture cohorts. Players with metacarpal fractures treated nonoperatively had a significant decline in their Wins Above Replacement (WAR) 2 seasons postinjury (1.37 point decline) in comparison to matched controls (0.84 point increase) (P = .02). There was no significant difference in WAR 1 or 2 seasons postinjury for players with metacarpal fractures treated operatively in comparison to the control cohort. CONCLUSIONS Major League Baseball players sustaining metacarpal fractures can expect to return to their preinjury performance levels following both nonoperative and operative treatment. However, players treated nonoperatively may witness a decline in their performance compared with peers over the long term. Orthopedic surgeons treating professional athletes with metacarpal fractures should consider these outcomes when counseling their patients and making treatment recommendations.

Kinematic and Kinetic Comparisons of Arm Slot Position Between High School and Professional Pitchers. Orthop J Sports Med 2023; 11:23259671221147874. [PMID: 37900864 PMCID: PMC10601404 DOI: 10.1177/23259671221147874] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Accepted: 10/21/2022] [Indexed: 10/31/2023] Open
Abstract
Background Throwing arm kinetics differ in pitchers at varying arm slot (AS) positions (frontal-plane arm position at ball release relative to the vertical axis). Purpose To determine how kinematic and kinetic values differ between professional and high school pitchers with varying AS positions, and whether these differences are similarly observed in both populations. Methods High school (n = 130) and professional (n = 288) pitchers threw 8 to 12 fastballs under 3-dimensional motion capture technology. Pitchers in each cohort were subdivided based on mean AS position at ball release: AS1 (least degree of AS: most overhand throwing styles), AS2 (intermediate degree of AS: three-quarter throwing styles), or AS3 (greatest degree of AS: most sidearm throwing styles). Kinetic and kinematic parameters were compared between groups. Study Design Controlled laboratory study. Results High school pitchers had a more overhand AS at ball release (50° ± 11°) compared with professional pitchers (58° ± 14°) (P < .001). In both cohorts, AS1 pitchers had significantly greater shoulder abduction (high school, P <0.001; professional, P <0.0001) and lateral trunk flexion (high school, P < 0.001; professional, P <0.0001) at ball release compared with AS3 pitchers. Professional pitchers with an AS3 position had significantly delayed timing of maximum upper trunk angular velocity compared with AS1 pitchers (64% ± 7% vs 57% ± 7% of pitch time, respectively; P < .0001). A significant positive correlation between AS and elbow flexion torque was found in high school pitchers (P = .002; β = 0.28), and a significant negative correlation between AS and elbow varus torque (P < .001; β = -0.22) and shoulder internal rotation torque (P < .001; β = -0.20) was noted in professional pitchers. Conclusion AS position was related to shoulder abduction and trunk lateral tilt. Professional and high school pitchers with varying AS positions did not experience similar changes in throwing arm kinetics. Clinical Relevance In professional pitchers, the earlier onset of maximum upper trunk angular velocity with overhand throwing style may reflect inappropriate pelvis-trunk timing separation, a parameter implicated in upper extremity injury, and the negative correlation between AS and elbow varus and shoulder internal rotation torque suggests that both excessive and minimal AS positions have negative implications.

Abstract
BACKGROUND The use of online search engines for health information is becoming common practice. We analyzed Google search queries to identify the most frequently asked topics and questions related to lateral epicondylitis ("tennis elbow") and the Web sites provided to address these questions. METHODS Four search terms for lateral epicondylitis were entered into Google Web Search. A list of the most frequently asked questions along with their associated Web sites was extracted and categorized by 2 independent reviewers. RESULTS A total of 400 questions were extracted with 168 associated Web sites. The most popular question topics were related to indications/management (39.0%), risks/complications (19.5%), and the ability to perform specific activities (18.8%). Frequently asked questions had to do with the duration of symptoms, self-management strategies (eg, brace use and self-massage), and the indications for surgery. The most common Web sites provided to address these questions were social media (27.5%), commercial (24.5%), academic (16.5%), and medical practice (16.3%). CONCLUSION The most frequently asked questions about lateral epicondylitis on Google centered around symptom duration and management, with most information originating from social media and commercial Web sites. Our data can be used to anticipate patient concerns and set expectations regarding the prognosis and management of lateral epicondylitis.

Prospective registration of randomized clinical trials for total shoulder arthroplasty is low: a systematic review. J Shoulder Elbow Surg 2023; 32:1763-1769. [PMID: 37224915 DOI: 10.1016/j.jse.2023.04.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Revised: 03/20/2023] [Accepted: 04/04/2023] [Indexed: 05/26/2023]
Abstract
BACKGROUND Prospective trial registration has become an important means of improving the transparency and reproducibility of randomized controlled trials (RCTs) and is recommended by the Journal of Shoulder and Elbow Surgery (JSES) per the Consolidated Standards of Reporting Trials (CONSORT) guidelines. Herein, we performed a cross-sectional evaluation of RCTs published in JSES from 2010 to present to determine the prevalence of trial registration and consistency of outcome reporting. METHODS The electronic database PubMed was searched to identify all RCTs on total shoulder arthroplasty (TSA) published in JSES from 2010 to 2022 using the search terms "randomized controlled trial" AND "shoulder" AND "arthroplasty OR replacement." RCTs were considered to be registered if they provided a registration number. For articles that were registered, authors also extracted the registry name, registration date, date of first enrollment, date of last enrollment, and if the primary outcomes reported in the registry were either (1) omitted, (2) newly introduced in the publication, (3) reported as a secondary outcome or vice versa, or (4) varied in timing of assessment compared to the publication. "Early" RCTs were considered those published from 2010 to 2016, whereas "later" RCTs were from 2017 to 2022. RESULTS Fifty-eight RCTs met inclusion criteria. There were 16 early RCTs and 42 later RCTs. Twenty-three of the 58 (39.7%) studies were registered, with 9 of 22 with an available registry (40.9%) of those being enrolled prior to patient enrollment. Nineteen of the registered studies (82.6%) provided the name of the registry and a registration number. The proportion of later RCTs that were registered was not significantly different from the early RCTs (45.2% vs. 25.0%, P = .232). Seven RCTs (31.8%) had at least 1 inconsistency compared with the registry. The most common discrepancy was the timing of the assessment (ie, follow-up period) reported in the publication vs. the registry. DISCUSSION Although JSES recommends prospective trial registration, less than half of shoulder arthroplasty RCTs are registered and more than 30% registered trials have at least 1 inconsistency with their registry record. More rigorous review of trial registration and accuracy is necessary to limit bias in published shoulder arthroplasty RCTs.

[PMID: 37086905 DOI: 10.1053/j.jfas.2023.04.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 04/03/2023] [Accepted: 04/09/2023] [Indexed: 04/24/2023]
Abstract
Patients with diabetes mellitus (DM) are at increased risk of complications following ankle fracture surgery. Previous research suggests that patients of low socioeconomic status are at increased risk of amputation following orthopedic complications. The purpose of this research was to determine if low socioeconomic status increases risk of below-knee amputation (BKA) following ankle fractures among patients with DM. The National Inpatient Sample (NIS) was queried from 2010 to 2014 to identify 125 diabetic patients who underwent ankle fracture surgical fixation followed by BKA. Two cohorts (BKA vs no BKA) and a multivariate logistic regression model were created to compare the effects of independent variables, including age, sex, race, primary payer, median household income by ZIP code, hospital location/teaching status, and comorbidities. The most predictive variables for BKA were concomitant peripheral vascular disease (odds ratio [OR] 5.35, 95% confidence interval [CI] 3.51-8.15), history of chronic diabetes-related medical complications (OR 3.29, CI 2.16-5.01), age in the youngest quartile (OR 2.54, CI 1.38-4.67), and male sex (OR 2.28, CI 1.54-3.36). Patient race and median household income were not significantly associated with BKA; however, risk of BKA was greater among patients with Medicaid (OR 2.23, CI 1.09-4.53) or Medicare (OR 1.85, CI 1.03-3.32) compared to privately insured patients. Diabetic inpatients with Medicaid insurance are at over twice the odds of BKA compared to privately insured patients following ankle fracture. Furthermore, peripheral vascular diseases, uncontrolled diabetes, younger age, and male sex each independently increase risk of BKA.

The Majority of Sports Medicine and Arthroscopy-Related Randomized Controlled Trials Reporting Nonsignificant Results Are Statistically Fragile. Arthroscopy 2023; 39:2071-2083.e1. [PMID: 36868530 DOI: 10.1016/j.arthro.2023.02.022] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 02/14/2023] [Accepted: 02/16/2023] [Indexed: 03/05/2023]
Abstract
PURPOSE To evaluate the robustness of sports medicine and arthroscopy related randomized controlled trials (RCTs) reporting nonsignificant results by calculating the reverse fragility index (RFI) and reverse fragility quotient (RFQ). METHODS All sports medicine and arthroscopic-related RCTs from January 1, 2010, through August 3, 2021, were identified. Randomized-controlled trials comparing dichotomous variables with a reported P value ≥ .05 were included. Study characteristics, such as publication year and sample size, as well as loss to follow-up and number of outcome events were recorded. The RFI at a threshold of P < .05 and respective RFQ were calculated for each study. Coefficients of determination were calculated to determine the relationships between RFI and the number of outcome events, sample size, and number of patients lost to follow-up. The number of RCTs in which the loss to follow-up was greater than the RFI was determined. RESULTS Fifty-four studies and 4,638 patients were included in this analysis. The mean sample size and loss to follow-up were 85.9 patients and 12.5 patients, respectively. The mean RFI was 3.7, signifying that a change of 3.7 events in one arm was needed to flip the results of the study from non-significant to significant (P < .05). Of the 54 studies investigated, 33 (61%) had a loss to follow-up greater than their calculated RFI. The mean RFQ was 0.05. A significant correlation between RFI with sample size (R2 = 0.10, P = .02) and the total number of observed events (R2 = 0.13, P < .01) was found. No significant correlation existed between RFI and loss to follow-up in the lesser arm (R2 = 0.01, P = .41). CONCLUSIONS The RFI and RFQ are statistical tools that allow the fragility of studies reporting nonsignificant results to be appraised. Using this methodology, we found that the majority of sports medicine and arthroscopy-related RCTs reporting nonsignificant results are fragile. CLINICAL RELEVANCE RFI and RFQ serve as tools that can be used to assess the validity of RCT results and provide additional context for appropriate conclusions.

Abstract
BACKGROUND National Institutes of Health (NIH) funding of orthopaedic surgery departments has historically lagged behind that of other surgical disciplines. In this study, we present an updated analysis of NIH grants awarded to orthopaedic surgery departments at U.S. medical schools and an evaluation of the characteristics of NIH-funded principal investigators (PIs). METHODS The NIH Research Portfolio Online Reporting Tools Expenditures and Results (RePORTER) database was queried for grants awarded to orthopaedic surgery departments in the 2015 to 2021 fiscal years. Funding totals were calculated for 4 categories: award mechanism, awarding institute, recipient institute, and PI. Trends in funding from 2015 to 2021 were determined and compared with the annual NIH budget. Funding awarded to orthopaedic surgery departments was compared with awards received by other surgical specialties in 2021. The characteristics of NIH-funded PIs and co-PIs were evaluated. Funding awarded to orthopaedic surgery departments in 2021 was compared with funding in 2014 as reported in a previous study. RESULTS In 2021, 287 grants were awarded to 187 PIs at 47 orthopaedic surgery departments for a total of $104,710,841, representing 0.4% of the overall NIH budget. The top 5 departments earned $41,750,321 (39.9%) of the total NIH funding for orthopaedic surgery. From 2015 to 2021, total funding increased by 79.7% (p < 0.001), but the rate of increase was not significantly different from that of the overall annual NIH budget (p = 0.469). In 2021, grants were most commonly awarded via the R01 mechanism (70.0% of total funding), with a median annual award of $397,144 (interquartile range [IQR], $335,017 to $491,248). The majority of grants (70.0%) supported basic science research, followed by translational (12.2%), clinical (9.4%), and educational (8.4%) research. NIH funding did not vary by the gender of the PI (p = 0.505), and the proportion of female PIs was significantly greater in 2021 than in 2014 (33.9% versus 20.5%, p = 0.009). Compared with other surgical departments, orthopaedic surgery departments ranked second-lowest in terms of the total NIH funding received in 2021. CONCLUSIONS NIH funding to orthopaedic surgery departments continues to be limited and lags behind that of other surgical subspecialties, which may create challenges in addressing the rising burden of musculoskeletal disease in the U.S. These findings highlight the importance of efforts to identify barriers to grant procurement in orthopaedic surgery.

Abstract
Massive irreparable rotator cuff tears (RCTs) are a commonly encountered orthopedic condition that can be difficult to treat. Several techniques have been described to manage these tears, with the implantable subacromial balloon spacer being one of the most recent. The device, which has only been approved for clinical use in the United States since 2021, functions by resisting the superior humeral head migration seen in the setting of massive RCTs and restoring normal shoulder biomechanics, as corroborated by cadaveric studies. However, results regarding clinical outcomes have been mixed to date, and further high-quality studies are needed to define the optimal use of the subacromial balloon spacer in the treatment of massive irreparable RCTs.

Influence of Race on Utilization and Outcomes in Shoulder Arthroplasty: A Systematic Review. JBJS Rev 2023; 11:01874474-202306000-00015. [PMID: 37335835 DOI: 10.2106/jbjs.rvw.23.00003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 06/21/2023]
Abstract
BACKGROUND Studies have shown that utilization and outcomes after shoulder arthroplasty vary by sociodemographic factors, highlighting disparities in care. This systematic review synthesized all available literature regarding the relationship between utilization and outcomes of shoulder arthroplasty and race/ethnicity. METHODS Studies were identified using PubMed, MEDLINE (through Ovid), and CINAHL databases. All English language studies of Level I through IV evidence that specifically evaluated utilization and/or outcomes of hemiarthroplasty, total shoulder arthroplasty, or reverse shoulder arthroplasty by race and/or ethnicity were included. Outcomes of interest included rates of utilization, readmission, reoperation, revision, and complications. RESULTS Twenty-eight studies met inclusion criteria. Since the 1990s, Black and Hispanic patients have demonstrated a lower utilization rate of shoulder arthroplasty compared with White patients. Although utilization has increased among all racial groups throughout the present decade, the rate of increase is greater for White patients. These differences persist in both low-volume and high-volume centers and are independent of insurance status. Compared with White patients, Black patients have a longer postoperative length of stay after shoulder arthroplasty, worse preoperative and postoperative range of motion, a higher likelihood of 90-day emergency department visits, and a higher rate of postoperative complications including venous thromboembolism, pulmonary embolism, myocardial infarction, acute renal failure, and sepsis. Patient-reported outcomes, including the American Shoulder and Elbow Surgeon's score, did not differ between Black and White patients. Hispanics had a significantly lower revision risk compared with White patients. One-year mortality did not differ significantly between Asians, Black patients, White patients, and Hispanics. CONCLUSION Shoulder arthroplasty utilization and outcomes vary by race and ethnicity. These differences may be partly due to patient factors such as cultural beliefs, preoperative pathology, and access to care, as well as provider factors such as cultural competence and knowledge of health care disparities. LEVEL OF EVIDENCE Level IV. See Instructions for Authors for a complete description of levels of evidence.

The learning curve for anatomic and reverse total shoulder arthroplasty: a systematic review. JSES REVIEWS, REPORTS, AND TECHNIQUES 2023; 3:150-159. [PMID: 37588447 PMCID: PMC10426533 DOI: 10.1016/j.xrrt.2022.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 12/28/2022]
Abstract
Background Despite the rising incidence of anatomic total shoulder arthroplasty (ATSA) and reverse total shoulder arthroplasty (RTSA) among surgeons, little is known about the learning curve associated with these procedures. The purpose of this systematic review was to (1) identify the learning curves associated with ATSA and RTSA, (2) evaluate the effect of the learning curves on clinical outcomes, and (3) determine the number of cases needed to achieve proficiency. Methods Four online databases [PubMed (NLM), MEDLINE (OVID), Cochrane Library (Wiley), and Scopus (Elsevier)] were systematically searched and screened according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. The search included results from the inception of each database to May 18, 2022. Data regarding study characteristics, patient demographics, learning curve analyses, patient reported outcome measures, range of motion, complication rates, and reoperation rates were collected. A quality assessment for each article was performed according to the Methodological Index for Nonrandomized Studies criteria. Results A total of 13 studies of fair to good quality were included for analysis (one of level II evidence, five of level III, and seven of level IV) with the majority originating from the United States [n = 8, 61.5%]. Overall, there were a total of 3381 cases (1861 RTSA and 1520 ATSA), with a mean patient age of 72.6 years [range: 45-92 years]. From the studies analyzed in this systematic review, for RTSA, the approximate average number of cases surgeons need to perform to move to an acceptable position on the RTSA learning curve is 25 cases. For ATSA, a wider range of 16-86 cases was derived as only two studies reported on ATSA. Conclusion Progression along the learning curve for RTSA and ATSA results in decreased operative times, improved patient-reported outcomes, and fewer complications. However, a true learning curve is difficult to quantify given the heterogeneity of reported outcome measures, individual surgeon experience at the time of data collection, and statistical analyses used across studies.

Abstract
Orthopaedic surgery remains one of the most competitive residency specialties, with the number of applicants outpacing the availability of residency positions each year. The purpose of this study was to analyze present-day orthopaedic surgery match data, identify differences between matched and unmatched applicants, and compare our findings to previous trends. Methods Applicant data from the National Resident Matching Program from 2016 to 2022 were analyzed. The number of matched and unmatched US allopathic senior orthopaedic applicants relative to the number of available positions was used to determine respective match rates. Performance metrics and applicant characteristics were compared by match status. Trends were compared with those of previous analysis from 2006 to 2014. Results The number of applicants increased from 863 in 2016 to 1,068 in 2022. The match rate decreased from 75% in 2016 to 66% in 2022 (p < 0.0001). Matched applicants had a higher number of contiguous ranks (12.3 vs. 6.5; p < 0.001), United States Medical Licensing Examination (USMLE) Step-1 score (248 vs. 240; p < 0.001), USMLE Step-2 score (255 vs. 247; p < 0.001), Alpha Omega Alpha (AOA) membership (38% vs. 13%; p < 0.001), and enrollment at a top 40 National Institutes of Health (NIH)-funded medical school (34% vs. 24%, p < 0.001). Compared with 2006 to 2014 data, a smaller percentage of matched applicants were enrolled in a top 40 NIH-funded medical school (34% vs. 37%, p = 0.013). The mean differences in USMLE Step-1 score (16 vs. 8.25 points, p < 0.001) and USMLE Step-2 score (16 vs. 8.25 points, p = 0.002) in favor of matched applicants nearly halved compared with that in 2006 to 2014. In addition, there was no longer a significant difference in the number of research products (abstracts, presentations, posters, and publications) between matched and unmatched applicants (p = 0.309). Conclusions Differences in the academic attributes of matched and unmatched orthopaedic surgery applicants have become less profound over time, making it increasingly difficult to predict a successful match based on USMLE Step scores, AOA membership, research productivity, and medical school research reputation. Future studies should evaluate differences in subjective metrics (e.g., away rotation and interview performance and letters of recommendation) by match status.

Forearm Pronation at Foot Contact: A Biomechanical Motion-Capture Analysis in High School and Professional Pitchers. Orthop J Sports Med 2023; 11:23259671221145233. [PMID: 37123995 PMCID: PMC10134138 DOI: 10.1177/23259671221145233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Accepted: 09/26/2022] [Indexed: 05/02/2023] Open
Abstract
Background It has previously been speculated that baseball pitchers who display excessive forearm pronation at foot contact (FC) have a higher propensity toward ulnar collateral ligament injury and subsequent surgery. Purpose To evaluate the association between degree of forearm pronation/supination at FC and throwing arm kinetics in high school and professional pitchers, at both the individual (intrapitcher) and the group (interpitcher) level. Study Design Descriptive laboratory study. Methods High school (n = 41) and professional (n = 196) pitchers threw 8 to 12 fastballs while being assessed with a 3-dimensional motion-capture system (480 Hz). Pitchers at each playing level were divided into a supination or pronation subgroup depending on degree of forearm pronation at FC. Regression models were built to observe the relationship between forearm pronation at FC and kinetic and kinematic parameters of interest. Results At both the individual and the group level of high school and professional pitchers, there was no significant correlation between forearm pronation at FC and elbow varus torque (P min = .21). For every 10° increase in forearm pronation at FC in the individual high school pitcher, elbow flexion at FC decreased by 5°, whereas maximum elbow extension velocity was achieved 0.6% later in the pitch. In addition, elbow medial force increased by 4.1 N and elbow varus torque increased by 0.8 N·m for every 10° increase in forearm supination at FC. For every 10° increase in forearm supination in the individual professional pitcher, ball velocity increased by 0.5 m/s, shoulder external rotation at FC decreased by 11°, and elbow medial force decreased by 5.5 N. Conclusion Supination- or pronation-predominant forearm motion during the pitch did not significantly differ between playing levels. Excessive forearm pronation at FC was not a significant risk factor for increased throwing arm kinetics for high school or professional pitchers. There was a weak positive association between forearm supination at FC and elbow varus torque in the individual high school pitcher. Ultimately, coaches and pitchers may be better served by redirecting their focus to other mechanical aspects of the pitch that may have stronger associations with injury risk implications as well as performance.

Abstract
Purpose To evaluate shoulder arthroscopy case volume for graduating United States orthopaedic surgery residents. Methods We used the Accreditation Council for Graduate Medical Education case log records to evaluate reports from academic years 2016 to 2020. Logs were queried for pediatric, adult, and total (pediatric and adult) cases. The 10th, 30th, 50th, and 90th percentiles of case volumes from 2016 to 2020 were presented to demonstrate case volume variability. Results There was a significant increase in the average number of total (70.7 ± 35 vs 81.8 ± 45; P < .001), adult (69 ± 34 vs 79.7 ± 44; P < .001), and pediatric (1.8 ± 2 vs 2.2 ± 3; P = .003) shoulder arthroscopy cases performed by orthopaedic surgery residents between the academic year 2016 and 2020. Residents were involved in more than 36 times the number of adult cases compared with pediatric cases in 2020 (79.7 ± 44 vs 2.2 ± 3; P < .001). The 90th percentile of residents performed 6 pediatric cases in 2020, compared with zero cases in the 30th percentile and lower. Conclusions Approximately one-third of orthopedic surgery residents graduate without having performed a pediatric shoulder arthroscopy. Clinical Relevance The findings from this study could help guide the revision of current Accreditation Council for Graduate Medical Education guidelines for orthopaedic surgery residents.

Abstract
The long head of the biceps and superior labrum should be evaluated as an interdependent functional unit. A focused patient history and physical examination including multiple provocative tests should be performed alongside advanced imaging studies to obtain an accurate diagnosis. Nonoperative treatment modalities including nonsteroidal anti-inflammatory drugs, glucocorticoid injections, and a standardized physical therapy regimen should be exhausted before operative intervention. Significant improvements in pain, functional outcomes, and quality of life are achieved in patients treated nonoperatively. Although these outcomes are less consistent for overhead athletes, return to play and performance metrics seem comparable to those who undergo surgery.

Abstract
The pathogenesis of primary glenohumeral arthritis (GHOA) is mediated by a complex interaction between osseous anatomy and the surrounding soft tissues. Recently, there has been growing interest in characterizing the association between the anterior shoulder joint capsule and primary GHOA because of the potential for targeted treatment interventions. Emerging evidence has shown substantial synovitis, fibrosis, and mixed inflammatory cell infiltrate in the anterior capsule of osteoarthritic shoulders. In addition, increased thickening of the anterior shoulder joint capsule has been associated with greater posterior glenoid wear and humeral head subluxation. While these findings suggest that anterior capsular disease may play a causative role in the etiology and progression of eccentric GHOA, further studies are needed to support this association. The purpose of this article is to review the pathogenesis of primary GHOA, contextualize current hypotheses regarding the role of the anterior capsule in the disease process, and provide directions for future research.

Abstract
Background Objective measures of research influence are being increasingly utilized to evaluate and compare academic faculty. However, traditional bibliometrics, such as the Hirsch index and article citation count, are biased by time-dependent factors and are limited by a lack of field normalization. The relative citation ratio (RCR) is a new field- and time-normalized article-level metric developed by the National Institutes of Health (NIH). Purpose/Hypothesis The purpose of this study was to evaluate the RCR among fellowship-trained academic sports medicine surgeons and to analyze physician factors associated with RCR values. We hypothesized that the mean RCR score for fellowship-trained academic sports medicine surgery faculty will fall above the NIH standard. Study Design Cross-sectional study. Methods A retrospective data analysis was performed using the iCite database for all fellowship-trained sports medicine surgery faculty associated with Accreditation Council for Graduate Medical Education-accredited orthopaedic surgery residency programs in December 2021. In eligible faculty, the mean RCR, weighted RCR, and total publication count were compared by sex, career duration, academic rank, and presence of additional degrees. A mean RCR value of 1.0 is the NIH-funded field-normalized standard. The data herein are presented as the median and interquartile range, in addition to the mean and standard deviation, to account for outliers of the mean and weighted RCR scores. Results A total of 624 fellowship-trained sports medicine surgery faculty members from 160 orthopaedic surgery residency programs were included in the analysis. Overall, faculty produced impactful research, with a median RCR of 1.6 (interquartile range, 1.0-2.2) and a median weighted RCR of 19.3 (interquartile range, 5.1-69.3). Advanced academic rank and career longevity were associated with increased weighted RCR and total publication count. All subgroups analyzed had an RCR value >1.0. Conclusion Study findings indicate that fellowship-trained academic sports medicine surgery faculty are highly productive and produce impactful research, as evidenced by the high median RCR value relative to the benchmark NIH RCR value of 1.0.

Abstract
Purpose The purpose of this review was to systematically evaluate the literature on pediatric shoulder arthroscopy and outline its indications, outcomes, and complications. Methods This systematic review was carried out in accordance with PRISMA guidelines. PubMed, Cochrane Library, ScienceDirect, and OVID Medline were searched for studies reporting the indications, outcomes, or complications in patients undergoing shoulder arthroscopy under the age of 18 years. Reviews, case reports, and letters to the editor were excluded. Data extracted included surgical techniques, indications, preoperative and postoperative functional and radiographic outcomes, and complications. The methodological quality of included studies was evaluated using the Methodological Index for Non-Randomized Studies (MINORS) tool. Results Eighteen studies, with a mean MINORS score of 11.4/16, were identified, including a total of 761 shoulders (754 patients). Weighted average age was 13.6 years (range, 0.83-18.8 years) with a mean follow-up time of 34.6 months (range, 6-115). As part of their inclusion criteria, 6 studies (230 patients) recruited patients with anterior shoulder instability and 3 studies recruited patients with posterior shoulder instability (80 patients). Other indications for shoulder arthroscopy included obstetric brachial plexus palsy (157 patients) and rotator cuff tears (30 patients). Studies reported a significant improvement in functional outcomes for arthroscopy indicated for shoulder instability and obstetric brachial plexus palsy. A significant improvement was also noted in radiographic outcomes and range of motion for obstetric brachial plexus palsy patients. The overall rate of complication ranged from 0% to 25%, with 2 studies reporting no complications. The most common complication was recurrent instability (38 patients of 228 [16.7%]). Fourteen of the 38 patients (36.8%) underwent reoperation. Conclusion Among pediatric patients, shoulder arthroscopy was indicated most commonly for instability, followed by brachial plexus birth palsy, and partial rotator cuff tears. Its use resulted in good clinical and radiographic outcomes with limited complications. Level of Evidence Systematic review of Level II to IV studies.

Preoperative allergy testing for patients reporting penicillin and cephalosporin allergies is economically justified in preventing infection after total shoulder arthroplasty. J Shoulder Elbow Surg 2023; 32:186-191. [PMID: 36108882 DOI: 10.1016/j.jse.2022.07.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 07/05/2022] [Accepted: 07/17/2022] [Indexed: 02/01/2023]
Abstract
BACKGROUND The use of alternative antibiotics to cefazolin has been associated with increased risk of infection after shoulder arthroplasty. Routine preoperative allergy testing in patients reporting penicillin and cephalosporin allergies increases the number able to receive cefazolin and may reduce the occurrence of infection after shoulder arthroplasty, but the financial viability of this practice is unclear. We used break-even modeling to determine the economic viability of routine preoperative allergy testing for infection prevention in total shoulder arthroplasty patients reporting penicillin and cephalosporin allergies. METHODS Allergy testing cost ($248.24), infection rates after shoulder arthroplasty following use of noncefazolin antibiotics (3.09%), and infection-related care costs ($55,243) were derived from the literature. A break-even equation using these variables was developed to determine the absolute risk reduction (ARR) in the infection rate that would economically justify the routine implementation of preoperative allergy testing. The number needed to treat was calculated from the ARR. RESULTS Preoperative allergy testing is considered economically justified if it prevents at least 1 infection out of 223 shoulder arthroplasties (ARR = 0.45%). These protocols remained economically viable at varying allergy testing costs, initial infection rates, and infection-related care costs. CONCLUSIONS Routine preoperative penicillin allergy testing is an economically justified infection prevention strategy among patients reporting penicillin and cephalosporin allergies in the setting of elective shoulder arthroplasty. Widespread implementation of this practice may considerably reduce the economic and societal burden associated with prosthetic infections.

Evaluation of the National Institutes of Health-Supported Relative Citation Ratio Among Fellowship-Trained American Orthopaedic Joint Reconstruction Surgery Faculty: A New Bibliometric Measure of Scientific Influence. J Arthroplasty 2023; 38:165-170. [PMID: 35940351 DOI: 10.1016/j.arth.2022.07.022] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Revised: 07/21/2022] [Accepted: 07/25/2022] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND The relative citation ratio (RCR), a novel National Institutes of Health-Supported measure of research productivity, allows for accurate interdisciplinary comparison of publication influence. This study evaluates the RCR of fellowship-trained adult reconstructive orthopaedic surgeons with the goal of analyzing potentially influential physician demographics. METHODS Adult Reconstruction Accreditation Council for Graduate Medical Education fellowship-trained faculty for orthopaedic residency programs were identified via departmental websites. The National Institutes of Health's iCite database was retrospectively reviewed for mean RCR, weighted RCR, and publication count by surgeon. Multivariate analyses were performed using the Wilcoxon rank-sum tests and analyses of variance testing to compare sex, career length, academic rank, and professional degrees in addition to an MD or DO. Significance was considered P < .05. RESULTS A total of 488 fellowship-trained adult reconstruction faculty from 144 programs were included in the analysis. Overall, the faculty recorded a median RCR of 1.65 (interquartile range: 1.01-2.28) and a median weighted RCR of 16.59 (interquartile range: 3.98-61.92). The weighted RCR and total number of publications were associated with academic rank and career longevity, while the mean RCR was associated with academic rank. The median RCR ranged from 1.12 to 1.87 for all subgroups. CONCLUSION Adult reconstruction faculty are exceptionally productive and generate highly impactful studies as evidenced by the high median RCR value relative to the National Institutes of Health standard value of 1.0. Our data have important implications in the assessment of grant outcomes, promotion, and continued evaluation of research influence within the hip and knee community.

Surgeon variation in glenoid bone reconstruction procedures for shoulder instability. J Shoulder Elbow Surg 2023; 32:133-140. [PMID: 36208672 DOI: 10.1016/j.jse.2022.09.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Revised: 08/22/2022] [Accepted: 09/04/2022] [Indexed: 11/14/2022]
Abstract
BACKGROUND Advances in the understanding and management of glenoid bone loss in shoulder instability have led to the development of alternative bony reconstruction techniques to the Latarjet using free bone grafts, but little is known about surgeon adoption of these procedures. This study sought to characterize surgeon variation in the use of glenoid bone reconstruction procedures for shoulder instability and ascertain reasons underlying procedure choice. METHODS A 9-question survey was created and distributed to 160 shoulder surgeons members of the PacWest Shoulder and Elbow Society, of whom 65 (41%) responded. The survey asked questions regarding fellowship training, years in practice, surgical volume, preferred methods of glenoid bone reconstruction, and reasons underlying treatment choice. RESULTS All surgeons completed a fellowship, with an equal number of sports medicine fellowship-trained (46%) and shoulder and elbow fellowship-trained (46%) physicians. The majority had been in practice for at least 6 years (6-10 years: 25%; >10 years: 59%). Most (78%) performed ≤10 glenoid bony reconstructions per year, and 66% indicated that bony procedures represented <10% of their total annual shoulder instability case volume. The open Latarjet was the preferred primary reconstruction method (69%), followed by open free bone block (FBB) (22%), arthroscopic FBB (8%), and arthroscopic Latarjet (1%). Distal tibia allograft (DTA) was the preferred graft (74%) when performing an FBB procedure, followed by iliac crest autograft (18%), and distal clavicle autograft (6%). The top 5 reasons for preferring Latarjet over FBB were the sling effect (57%), the autologous nature of the graft (37%), its robust clinical evidence (22%), low cost (17%), and availability (11%). The top 5 reasons for choosing an FBB procedure were less anatomic disruption (58%), lower complication rate (21%), restoration of articular cartilage interface (16%), graft versatility (11%), and technical ease (11%). Only 20% of surgeons indicated always performing a bony glenoid reconstruction procedure in the noncontact athlete with less than 20% glenoid bone loss. However, that percentage rose to 62% when considering a contact athlete with the same amount of bone loss. CONCLUSIONS Although open Latarjet continues to be the most popular glenoid bony primary reconstruction procedure in shoulder instability, nearly 30% of shoulder surgeons in the western United States have adopted FBB techniques as their preferred treatment modality--with DTA being the most frequently used graft. High-quality comparative clinical effectiveness research is needed to reduce decisional conflict and refine current evidence-based treatment algorithms.

Neighborhood socioeconomic disadvantage does not predict outcomes or cost after elective shoulder arthroplasty. J Shoulder Elbow Surg 2022; 31:2465-2472. [PMID: 35671927 DOI: 10.1016/j.jse.2022.04.023] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2022] [Revised: 04/17/2022] [Accepted: 04/24/2022] [Indexed: 02/01/2023]
Abstract
BACKGROUND There is growing evidence that the variation in value of shoulder arthroplasty may be mediated by factors external to surgery. We sought to determine if neighborhood-level socioeconomic deprivation is associated with postoperative outcomes and cost among patients undergoing elective shoulder arthroplasty. METHODS We identified 380 patients undergoing elective total shoulder arthroplasty (anatomic or reverse) between 2015 and 2018 in our institutional registry with minimum 2-year follow-up. Each patient's home address was mapped to the area deprivation index in order to determine the level of socioeconomic disadvantage. The area deprivation index is a validated composite measure of 17 census variables encompassing income, education, employment, and housing conditions. Patients were categorized into 3 groups based on socioeconomic disadvantage (least disadvantaged [deciles 1-3], middle group [4-6], and most disadvantaged [7-10]). Bivariate analysis was performed to determine associations between the level of socioeconomic deprivation with hospitalization time-driven activity-based costs and 2-year postoperative American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE), and pain intensity scores. RESULTS Overall 19% of patients were categorized as most disadvantaged. These patients were found to have equivalent preoperative pain intensity (P = .51), SANE (P = .50), and ASES (P = .72) scores compared to the middle and least disadvantaged groups, as well as similar outcome improvement at 2 years postoperatively (ASES): least disadvantaged group [35.7-84.3], middle group [35.1-82.4], and most disadvantaged group [37.1-84.0] [P = .56]; SANE: least disadvantaged group [31.8-87.1], middle group [30.8-84.8], and most disadvantaged group [34.2-85.1] [P = .42]; and pain: least disadvantaged group [6.0-0.97], middle group [6-0.97], and most disadvantaged group [5.6-0.80] [P = .88]. No differences in hospitalization costs were noted between groups (P = .77). CONCLUSIONS Patients undergoing elective shoulder arthroplasty residing in the most disadvantaged neighborhoods demonstrate equivalent preoperative and postoperative outcomes as others, without incurring higher costs. These findings support continued efforts to provide equitable access to orthopedic care across the socioeconomic spectrum.

Abstract
Background A growing number of patients use the internet to learn about their conditions and management options, but there may exist a disconnect between the readability of online education materials and a patient's health literacy. This issue is of particular relevance for shoulder conditions, where even with traumatic injuries (eg, clavicle fracture, shoulder dislocation), treatment is discretionary, directed primarily at quality of life, and therefore highly preference-sensitive.The purpose of this study was to utilize multiple readability algorithms to calculate the readability of the American Academy of Orthopaedic Surgeons (AAOS) patient education materials pertaining to diseases and conditions of the shoulder. Methods Online patient education articles from the AAOS pertaining to diseases and conditions of the shoulder were reviewed. The articles were modified for analysis using Readability Pro and readability scores were computed using the following 9 algorithms: Flesch-Kincaid Grade Level, Flesch Reading Ease, Gunning Fog Index, Coleman-Liau Index, Simple Measure of the Gobbledygook Index (SMOG), Automated Readability Index, FORCAST, and New Dale and Chall Index. A list of suggested word changes to improve the readability of included articles was compiled from Readable Pro. The average number of illustrations (images and/or videos) included per article was documented. Results Twenty-eight articles were included for analysis. For each of the algorithms studied, the average scores were as follows: Flesch Kincaid Grade Level was 8.8 ± .8 [range, 7.2-10.2]; recommended score: ≤ 8.0, Flesch Reading Ease 54.3 ± 5.3 [range, 45.3-64.1]; recommended score: ≥ 60, Gunning Fog 10.8 ± 1.2 [range, 8.3-13.1]; recommended score: ≤ 8.0, Coleman-Liau 11.2 ± .9 [range, 9.2-12.9]; recommended score: ≤8.0, SMOG index 11.4 ± .8 [range, 9.2-12.9]; recommended score: ≤ 8.0 , Automated Readability Index 8.4 ± .8 [range, 6.9-10.0]; recommended score: ≤ 8.0, FORCAST 11.2 ± .4 [range, 10.2-12.0]; recommended score: ≤ 9.0, and New Dale and Chall Index 5.8 ± .5 [range, 4.9-7.2 recommended score: ≤ 6.0-6.9]. The average number of illustrations per article was 4.5 ± 3.1 [range, 1-14]. Conclusion The readability of most patient education materials from the AAOS pertaining to diseases and conditions of the shoulder is higher than recommended across a variety of algorithms. Efforts to revise the readability of online education materials are important to facilitate shared decision-making, particularly in practice settings where most decisions are preference-sensitive.

Abstract
Analyze new NIH-Supported bibliometric tool, the relative citation ratio (RCR). Evaluate research productivity among fellowship trained Orthopedic Spine Surgeons. Conduct demographic analysis of research productivity among fellowship trained Orthopedic Spine Surgeons.
Background Publication metrics have been traditionally used to compare research productivity amongst academic faculty. However, traditional bibliometrics lack field-normalization and are often biased towards time-dependent publication factors. The National Institutes of Health (NIH) has developed a new, field-normalized, article-level metric, known as the “relative citation ratio” (RCR), that can be used to make accurate self, departmental, and cross-specialty comparisons of research productivity. This study evaluates the use of the RCR amongst academic orthopedic spine surgery faculty and analyzes physician factors associated with RCR values. Methods A retrospective data analysis was performed using the iCite database for all fellowship trained orthopedic spine surgery (OSS) faculty associated with Accreditation Council for Graduate Medical Education (ACGME)-accredited orthopedic surgery residency program. Mean RCR, weighted RCR, and total publication count were compared by sex, career duration, academic rank, and presence of additional degrees. A value of 1.0 is the NIH-funded field-normalized standard. Student t-tests were used for two-group analyses whereas the analysis of variance tests (ANOVA) was used for between-group comparisons of three or more subgroups. Statistical significance was achieved at P < 0.05. Results A total of 502 academic OSS faculty members from 159 institutions were included in the analysis. Overall, OSS faculty were highly productive, with a median RCR of 1.62 (IQR 1.38-2.32) and a median weighted RCR of 68.98 (IQR 21.06-212.70). Advancing academic rank was associated with weighted RCR, career longevity was associated with mean RCR score, and male sex was associated with having increased mean and weighted RCR scores. All subgroups analyzed had an RCR value above 1.0. Conclusions Academic orthopedic spine surgery faculty produce impactful research as evidenced by the high median RCR relative to the standard value set by the NIH of 1.0. Our data can be used to evaluate research productivity in the orthopedic spine community.

Abstract
BACKGROUND Publication metrics are used to evaluate and compare research productivity among academic faculty. However, traditional bibliometrics, such as the Hirsch index and article citation count, are limited by lack of field-normalization and yield inaccurate cross-specialty comparisons. Herein, we evaluate the use of a new field-normalized article-level metric developed by the National Institutes of Health (NIH), known as the relative citation ratio (RCR), among American Shoulder and Elbow Surgeons (ASES) fellowship faculty and analyzed physician factors associated with RCR values. METHODS A retrospective data analysis was performed using the iCite database for all shoulder and elbow surgery fellowship faculty listed on the American Shoulder and Elbow Surgeons (ASES) directory as of November 14, 2021. Mean RCR, weighted RCR, and total publication count were compared by sex, career duration, academic rank, and presence of additional degrees. Mean RCR represents the total number of article citations per year of a publication divided by the average number of citations per year received by NIH-funded papers in the same field; mean RCR serves as a measure of overall research impact. A value of 1.0 is the NIH-funded field-normalized standard. The weighted RCR represents the sum of all article-level RCR scores and is a measure of overall research productivity. Student t tests were used for two-group analyses whereas analyses of variance were used for between-group comparisons of 3 or more subgroups. RESULTS A total of 145 ASES fellowship faculty members from 33 fellowship programs were included in the analysis. Overall, ASES fellowship faculty produced highly impactful research with a median RCR of 1.8 (interquartile range [IQR] 1.4-2.3) and a median weighted RCR of 67.0 (IQR 21.1-212.7). Advanced academic rank and career longevity were associated with increased weighted RCR and total publication count. All subgroups analyzed had an RCR value above 1.0. CONCLUSIONS ASES fellowship faculty are exceptionally productive and produce highly impactful research, as evidenced by the high median RCR value relative to the benchmark NIH RCR value of 1.0. This information can be used as a standard to assess the improvement of grant outcomes, promotion, fellowship education, and continued evaluation of research productivity in the shoulder and elbow community.

Abstract
Background It is critical for orthopedic surgery residents and residency programs to have a current understanding of the content and resources utilized by the Orthopedic In-Training Examination (OITE) to continuously guide study and educational efforts. This study presents an updated analysis of the shoulder and elbow section of the OITE. Methods All OITE questions, answers, and references from 2013 to 2019 were reviewed. The number of shoulder and elbow questions per year was recorded, and questions were analyzed for topic, imaging modalities, cognitive taxonomy, and references. We compared our data to the results of a previous study that analyzed shoulder and elbow OITE questions from 2002 to 2007 to examine trends and changes in this domain overtime. Results There were 177 shoulder and elbow questions (126 shoulder, 71.2%; 51 elbow, 28.8%) of 1863 OITE questions (9.5%) over a 7-year period. The most commonly tested topics included degenerative joint disease/stiffness/arthroplasty (31.6%), anatomy/biomechanics (16.9%), instability/athletic injury (15.3%), trauma (14.7%), and rotator cuff (13.6%). Half of all questions involved clinical management decisions (49.7%). A total of 417 references were cited from 56 different sources, the most common of which were the Journal of Shoulder and Elbow Surgery (23.3%), Journal of the American Academy of Orthopaedic Surgeons (20.4%), and Journal of Bone and Joint Surgery (American Volume) (16%). The average time lag from article publication to OITE reference was 7.7 years. Compared with a prior analysis from 2002 to 2007, there was a significant increase in the number of shoulder and elbow questions on the OITE (5.5% to 9.5%; P < .001). Recent exams incorporated more complex multistep treatment questions (4.4% vs. 49.7%; P < .001) and fewer recall questions (42.2% vs. 22%; P < .001). There was a significant increase in the use of imaging modalities (53.3% vs. 79.1%; P < .001). No significant differences in the distribution of question topics were found. Conclusions The percentage of shoulder and elbow questions on the OITE has nearly doubled over the past decade with greater emphasis on critical thinking (eg, clinical management decisions) over recall of facts. These findings should prompt educators to direct didactic efforts (eg, morning conferences and journal club) toward case-based learning to foster critical thinking and clinical reasoning skills.

Abstract
Purpose To evaluate graduating orthopaedic resident case volume and variability for ankle arthroscopy from 2016 to 2020. Methods The Accreditation Council for Graduate Medical Education surgical case log data from 2016 to 2020 for graduating United States orthopaedic surgery residents was assessed. Arthroscopy procedures of the leg/ankle were categorized. The average number of cases performed per resident was compared from 2016 to 2020 to determine the percent change in case volume. The 10th, 30th, 50th, 70th, and 90th percentiles of case volumes from 2016 to 2020 were presented to demonstrate case volume variability. Results There was no significant change in the average number of leg/ankle arthroscopy cases from 2016 to 2020 (6.2 ± 5 [range 0-35] vs 6.1 ± 6 [range 0-76] P = .732), despite a 19% increase in the average number of total leg/ankle procedures performed over time (168.4 ± 47 [range 55-414] in 2016; 200.8 ± 57 in 2020 [range 67-601], P < .001). There was wide variability in ankle arthroscopy case volume among residents. The 90th percentile of residents performed 13 cases in 2020, compared with 5 in 50th percentile, and 1 in the 10th percentile. Conclusions Orthopaedic surgery resident exposure to ankle arthroscopy has remained low and highly variable overtime, despite an overall increase in the total number of leg/ankle procedures performed. Clinical Relevance Understanding ankle arthroscopy in case volume and variability is important for programs to ensure that orthopaedic residents are gaining adequate exposure to increasingly popular procedures. Orthopaedic surgery residency programs should explore methods to increase resident exposure to ankle arthroscopy.

Defining Minimal Clinically Important Difference and Patient Acceptable Symptom State After the Latarjet Procedure. Am J Sports Med 2022; 50:2761-2766. [PMID: 35850119 DOI: 10.1177/03635465221107939] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/31/2023]
Abstract
BACKGROUND The Latarjet procedure is one of the most well-established treatment options for anterior shoulder instability. However, meaningful clinical outcomes after this surgery have not been defined. PURPOSE This study aimed to establish the minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS) for commonly used outcome measures in patients undergoing the Latarjet procedure and determine correlations between preoperative patient characteristics and achievement of MCID or PASS. STUDY DESIGN Case series; Level of evidence, 4. METHODS A multicenter retrospective review at 4 institutions was performed to identify patients undergoing primary open Latarjet procedure with minimum 2-year follow-up. Data collected included patient characteristics (age, sex, sports participation), radiological parameters (glenoid bone loss, off-track Hill-Sachs lesion), and 4 patient-reported outcome measures (collected preoperatively and 2 years postoperatively): the American Shoulder and Elbow Surgeons (ASES) score, the Single Assessment Numeric Evaluation (SANE), the visual analog scale (VAS) for pain, and the Western Ontario Shoulder Instability Index (WOSI). The MCID and PASS for each outcome measure were calculated, and Pearson and Spearman coefficient analyses were used to identify correlations between MCID or PASS and preoperative variables (age, sex, sports participation, glenoid bone loss, off-track Hill-Sachs lesion). RESULTS A total of 156 patients were included in the study. The MCID values for ASES, SANE, VAS pain, and WOSI were calculated to be 9.6, 12.4, 1.7, and 254.9, respectively. The PASS values for ASES, SANE, VAS pain, and WOSI were 86.0, 82.5, 2.5, and 571.0, respectively. The rates of patients achieving MCID were 61.1% for VAS pain, 71.6% for ASES, 74.1% for SANE, and 84.2% for WOSI. The rates of achieving PASS ranged from 78.4% for WOSI to 84.0% for VAS pain. There was no correlation between any of the studied preoperative variables and the likelihood of achieving MCID or PASS. CONCLUSION This study defined MCID and PASS values for 4 commonly used outcome measures in patients undergoing the Latarjet procedure. These findings are essential for incorporating patient perspectives into the clinical effectiveness of the Latarjet procedure and provide valuable parameters for the design and interpretation of future clinical trials.

Abstract
Background This study aims to identify the most frequently cited articles published in the Journal of Arthroplasty (JOA) and to analyze the trends in the content and contributors of the literature within the journal. Methods The 100 most cited articles published in the JOA were accessed using the Scopus database. The number of citations, year of publication, level of evidence (LOE), article type, country of origin, and contributing institution were each recorded for each article. Results The United States (63%) was the most prolific publishing nation. The 1990s (30%) and 2000s (47%) were the most productive decades. The most common article category was clinical outcomes (33%), followed by technical note (16%) and biomechanics (14%). The plurality of the top 100 articles were well-designed case-control or cohort studies of LOE II (46%) followed by LOE V (32%) and LOE I (11%). Conclusions Using citation analysis, the most influential articles in the JOA were comprehensively and objectively analyzed. The most popular fields of research involved clinical outcomes (33%) and technical note (16%), both of which increase an article’s likelihood of being highly cited. Knowledge of the most influential articles in the JOA allows for appreciation of current and potential future areas of literature regarding diagnosis, management, and outcome of a patient undergoing arthroplasty.

Evaluation of the Relative Citation Ratio Among Academic Orthopedic Hand Surgeons: A Novel Measure of Research Impact. Cureus 2022; 14:e25362. [PMID: 35774708 PMCID: PMC9236682 DOI: 10.7759/cureus.25362] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/26/2022] [Indexed: 11/13/2022] Open
Abstract
Background: Publication metrics such as article citation count and the Hirsch index (h-index) are used to evaluate research productivity among academic faculty. However, these bibliometric indices are not field-normalized and yield inaccurate cross-specialty comparisons. We evaluate the use of the relative citation ratio (RCR), a new field-normalized article-level metric developed by the National Institutes of Health (NIH), among academic orthopedic hand surgeons and analyze physician factors associated with RCR values. Methods: A retrospective analysis was performed using the iCite database. Fellowship-trained orthopedic hand surgeons affiliated with accredited orthopedic surgery residency programs were included. Mean RCR, weighted RCR, and publication count were compared by sex, career duration, academic rank, and presence of additional degrees. Mean RCR represents the total number of citations per year of a publication divided by the average number of citations per year received by NIH-funded papers in the same field. Mean RCR serves as a measure of overall research impact. A value of 1.0 is the NIH-funded field-normalized standard. Weighted RCR is the sum of all article-level RCR scores and represents overall research productivity. Results: A total of 620 academic orthopedic hand surgeons from 164 programs were included. These physicians produced highly impactful research with a median RCR of 1.27 (interquartile range [IQR] 0.86-1.66). Weighted RCR was associated with advanced degree, advanced academic rank, and longer career duration. Conclusions: Fellowship-trained academic orthopedic hand surgeons produce highly impactful research. Our benchmark data can be used to assess grant outcomes, promotion, and continued evaluation of research productivity within the hand surgery community.

Wide variability of shoulder and elbow case volume in orthopedic surgery residency. J Shoulder Elbow Surg 2022; 31:437-444. [PMID: 34358667 DOI: 10.1016/j.jse.2021.06.023] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Revised: 06/16/2021] [Accepted: 06/28/2021] [Indexed: 02/01/2023]
Abstract
BACKGROUND Despite the growing popularity of certain shoulder and elbow procedures (eg, shoulder arthroplasty), resident exposure to these surgeries remains unclear. This study sought to evaluate trends in graduating orthopedic resident case volumes of commonly performed shoulder and elbow procedures. METHODS The Accreditation Council for Graduate Medical Education (ACGME) surgical case log data from 2016 to 2020 for graduating US orthopedic surgery residents was assessed. Procedures of the shoulder and humerus/elbow were categorized into predefined ACGME categories: repair/revision/reconstruction, fracture/dislocation, and arthroscopy. The average number of cases performed per resident in each of these categories was directly compared from 2016 to 2020. The 10th and 90th percentiles of case volumes within each category of procedures was compared from 2016 and 2020. RESULTS There was a 31% increase in the number of shoulder repair/revision/reconstruction cases between 2016 and 2020 (average: 27.5 to 36.1; P < .001), followed by a 23% increase for elbow fracture/dislocation (24.4 to 30; P < .001), 21% increase for elbow repair/revision/reconstruction (10.6 to 12.8; P < .001), and 16% increase for shoulder arthroscopy (69 to 79.7; P < .001). No significant changes were found for shoulder fracture/dislocation and elbow arthroscopy. There was a wide case volume variability for each procedure, particularly for shoulder repair/revision/reconstruction, where there was a nearly 5-fold difference in the number of cases performed between the 10th and 90th percentiles of residents in 2020 (13 vs. 62 cases, respectively). CONCLUSIONS The case category shoulder repair/revision/reconstruction has seen the largest relative increase in the shoulder and elbow case volume of graduating orthopedic surgery residents, most likely reflecting the national rising trends of shoulder arthroplasty. However, our study shows that there is wide variability in resident exposure to these cases. Implementation of shoulder arthroplasty case minimum requirements might help reduce case variability and discrepancies in resident education.

Nonoperative treatment of distal humerus fractures in the elderly yields satisfactory functional outcomes and low conversion to delayed surgery: a systematic review. JSES REVIEWS, REPORTS, AND TECHNIQUES 2022; 2:96-102. [PMID: 37588281 PMCID: PMC10426674 DOI: 10.1016/j.xrrt.2021.10.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Indexed: 08/18/2023]
Abstract
Background Distal humerus fractures (DHFs) pose a treatment challenge in elderly patients. We sought to systematically review and report the clinical outcomes of the nonoperative approach (eg, "bag of bones") for the treatment of these injuries and the rate of conversion to delayed surgery. Methods A comprehensive review of the literature using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines was conducted. Studies involving outcomes after nonoperative treatment of DHF in patients >65 years of age were included from 1985 to present. Data regarding patient age, DHF type, nonoperative treatment method, complications, conversion to delayed surgery, range of motion, union rate, and surgeon- and patient-reported outcome measures were extracted. Results A total of five studies met inclusion criteria (all level IV evidence), yielding a total of 143 patients (mean age: 73.5 years to 87.4 years) with 7.1 months to 55 months of follow-up. The mean Mayo Elbow Performance Index scores were good to excellent across several studies (range 83-93.1). Multiple studies reported good range of motion (mean arc of motion: 81 to 106 degrees) and low levels of upper extremity disability (mean Quick Disability of the Arm-Shoulder-Hand scores: 31.3 to 38.5) at the final follow-up. The rate of conversion to total elbow arthroplasty and operative fixation ranged from 0% to 7.5% and 0% to 5%, respectively. Conclusion Nonoperative management of distal humerus fractures in the elderly seems to be associated with acceptable functional outcomes and low rates of delayed surgery. This information is important for patient counseling and treatment decision-making.
