Orthopaedic Surgery Attrition Before Board Certification: A National-Cohort Study of US MD Graduates in Orthopaedic Surgery Residency Programs.

Little is known about attrition before American Board of Orthopaedic Surgery (ABOS) board certification for orthopaedic residents training in Accreditation Council for Graduate Medical Education (ACGME)-accredited orthopaedics programs. This national-cohort study examined orthopaedic surgery attrition, associated risk factors, and specialties pursued by residents who left orthopaedics. From August 2022 through July 2023, we analyzed deidentified, individual-level data from the Association of American Medical Colleges for 129,860 US MD-granting medical-school matriculants in academic years 1993 to 1994 through 2000 to 2001. Graduates with records of training ≥1 year in orthopaedic surgery during GME and of board certification as of May 2020 were included. Retention was defined as being ABOS-certified; attrition was defined as being certified by another specialty board and not ABOS. We identified variables independently associated with attrition from orthopaedics using multivariable logistic regression analysis and reported adjusted odds ratios (OR) and 95% confidence intervals (CI). Of 4,319 US medical-school graduates from 1997 to 2009 with ≥1 year of orthopaedic surgery GME, 4,085 (94.6%) obtained ABOS board certification (retention) and 234 did not (attrition). Women (OR 2.8, 95% CI 2.0-3.9), first-generation college graduates (OR 1.6, 95% CI 1.1-2.2), Asians (OR 1.9, 95% CI 1.4-2.7), and residents who placed greater importance on innovation/research in choosing medicine as a career (OR 1.4, 95% CI 1.1-1.7) and completed ≥1 year of research during GME (OR 2.4, 95% CI 1.7-3.5) were more likely to leave orthopaedics. Overall, 121 trainees who left orthopaedics selected surgical specialties for board certification, most commonly plastic surgery (n = 66) and general surgery (n = 45). The increased risk of attrition among women, Asians, first-generation college graduates, and trainees endorsing higher importance of innovation/research in choosing medicine and participating in research during GME raises concerns about the potential loss of underrepresented groups among orthopaedic surgeons and surgeon-scientists. Efforts to mitigate attrition among residents in high-risk groups are warranted.

Management of Femoral Neck Fractures in Patients Age ≥50 Years by American Board of Orthopaedic Surgery Part II Examination Candidates.

Assess associations between fellowship training, procedure, and performance in femoral neck fracture (FNF) surgery on adults by American Board of Orthopaedic Surgery (ABOS) Part II Examination candidates. ABOS SCRIBE database exam years 2007-2020. 6,777 candidates performing 39,283 FNF surgeries on adults age ≥ 50 years. Fellowship training. Case volume; procedure performed: internal fixation (IF), hemiarthroplasty (HA), or total hip arthroplasty (THA); complications; readmission; reoperation. Over the observation period, fewer candidates reported FNF surgery (68% overall, -0.6%/year, R2=0.80) while more candidates reported fellowship training (87% overall, +1.4%/year, R2=0.81). The rate of any complication was significantly associated with fellowship training (32% overall, p<0.001). Readmission (12%, p=0.080) and reoperation (5%, p=0.531) were not significantly associated with fellowship training. The odds of any complication (odds ratio [OR]=-0.03 [95% CI -0.07 to -0.001] per 10 cases) and surgical complication (OR=-0.12 [95% CI -0.17 to -0.07] per 10 cases) were negatively associated with candidate FNF case volume. 3,396 THA for FNF were performed (8% of cases). THA use increased 25 cases/year (R2=0.83) and was associated with adult reconstruction (p<0.001) and oncology (p<0.001) fellowship training. Any complication of THA for FNF (32%, p=0.261), readmission (9% overall, p=0.321), and reoperation (5%, p=0.200) were not significantly associated with fellowship training. Between 2007-2020, femoral neck fracture surgery was performed by fewer ABOS Part II Examination candidates and there was greater use of THA. Over this time period there was a greater prevalence of fellowship training but complications were not associated with fellowship training. Complications were associated with FNF case volume.

The Rapid Development of Artificial Intelligence: GPT-4's Performance on Orthopedic Surgery Board Questions.

Advances in artificial intelligence and machine learning models, like Chat Generative Pre-trained Transformer (ChatGPT), have occurred at a remarkably fast rate. OpenAI released its newest model of ChatGPT, GPT-4, in March 2023. It offers a wide range of medical applications. The model has demonstrated notable proficiency on many medical board examinations. This study sought to assess GPT-4's performance on the Orthopaedic In-Training Examination (OITE) used to prepare residents for the American Board of Orthopaedic Surgery (ABOS) Part I Examination. The data gathered from GPT-4's performance were additionally compared with the data of the previous iteration of ChatGPT, GPT-3.5, which was released 4 months before GPT-4. GPT-4 correctly answered 251 of the 396 attempted questions (63.4%), whereas GPT-3.5 correctly answered 46.3% of 410 attempted questions. GPT-4 was significantly more accurate than GPT-3.5 on orthopedic board-style questions (P<.00001). GPT-4's performance is most comparable to that of an average third-year orthopedic surgery resident, while GPT-3.5 performed below an average orthopedic intern. GPT-4's overall accuracy was just below the approximate threshold that indicates a likely pass on the ABOS Part I Examination. Our results demonstrate significant improvements in OpenAI's newest model, GPT-4. Future studies should assess potential clinical applications as AI models continue to be trained on larger data sets and offer more capabilities. [Orthopedics. 2024;47(2):e85-e89.].

Comparison of ChatGPT-3.5, ChatGPT-4, and Orthopaedic Resident Performance on Orthopaedic Assessment Examinations.

Artificial intelligence (AI) programs have the ability to answer complex queries including medical profession examination questions. The purpose of this study was to compare the performance of orthopaedic residents (ortho residents) against Chat Generative Pretrained Transformer (ChatGPT)-3.5 and GPT-4 on orthopaedic assessment examinations. A secondary objective was to perform a subgroup analysis comparing the performance of each group on questions that included image interpretation versus text-only questions. The ResStudy orthopaedic examination question bank was used as the primary source of questions. One hundred eighty questions and answer choices from nine different orthopaedic subspecialties were directly input into ChatGPT-3.5 and then GPT-4. ChatGPT did not have consistently available image interpretation, so no images were directly provided to either AI format. Answers were recorded as correct versus incorrect by the chatbot, and resident performance was recorded based on user data provided by ResStudy. Overall, ChatGPT-3.5, GPT-4, and ortho residents scored 29.4%, 47.2%, and 74.2%, respectively. There was a difference among the three groups in testing success, with ortho residents scoring higher than ChatGPT-3.5 and GPT-4 (P < 0.001 and P < 0.001). GPT-4 scored higher than ChatGPT-3.5 (P = 0.002). A subgroup analysis was performed by dividing questions into question stems without images and question stems with images. ChatGPT-3.5 was more correct (37.8% vs. 22.4%, respectively, OR = 2.1, P = 0.033) and ChatGPT-4 was also more correct (61.0% vs. 35.7%, OR = 2.8, P < 0.001), when comparing text-only questions versus questions with images. Residents were 72.6% versus 75.5% correct with text-only questions versus questions with images, with no significant difference (P = 0.302). Orthopaedic residents were able to answer more questions accurately than ChatGPT-3.5 and GPT-4 on orthopaedic assessment examinations. GPT-4 is superior to ChatGPT-3.5 for answering orthopaedic resident assessment examination questions. Both ChatGPT-3.5 and GPT-4 performed better on text-only questions than questions with images. It is unlikely that GPT-4 or ChatGPT-3.5 would pass the American Board of Orthopaedic Surgery written examination.

Operative and Nonoperative Treatment of Humeral Shaft Fractures: A Cost-Effectiveness Analysis.

Decision-making with regard to the treatment of humeral shaft fractures remains under debate. The cost-effectiveness of these treatment options has yet to be established. This study aims to compare the cost-effectiveness of operative treatment with that of nonoperative treatment of humeral shaft fractures. We developed a decision tree for treatment options. Surgical costs included the ambulatory surgical fee, physician fee, anesthesia fee, and, in the sensitivity analysis, lost wages during recovery. We used the Current Procedural Terminology codes from the American Board of Orthopaedic Surgery to determine physician fees via the U.S. Centers for Medicare & Medicaid Services database. The anesthesia fee was obtained from the national conversion factor and mean operative time for included procedures. We obtained data on mean wages from the U.S. Bureau of Labor and data on weeks missed from a similar study. We reported functional data via the Disabilities of the Arm, Shoulder and Hand (DASH) scores obtained from existing literature. We used rollback analysis and Monte Carlo simulation to determine the cost-effectiveness of each treatment option, presented in dollars per meaningful change in DASH score, utilizing a $50,000 willingness-to-pay (WTP) threshold. The cost per meaningful change in DASH score for operative treatment was $18,857.97 at the 6-month follow-up and $25,756.36 at the 1-year follow-up, by Monte Carlo simulation. Wage loss-inclusive models revealed values that fall even farther below the WTP threshold, making operative management the more cost-effective treatment option compared with nonoperative treatment in both settings. With an upward variation of the nonoperative union rate to 84.17% in the wage-exclusive model and 89.43% in the wage-inclusive model, nonoperative treatment instead became more cost-effective. Operative management was cost-effective at both 6 months and 1 year, compared with nonoperative treatment, in both models. Operative treatment was found to be even more cost-effective with loss of wages considered, suggesting that an earlier return to baseline function and, thus, return to work are important considerations in making operative treatment the more cost-effective option.

Analysis of Academic Accomplishments and Demographics for Elected Presidents of National Orthopedic Surgery Organizations in the United States.

This study analyzed the academic accomplishments and demographics of elected presidents of the American Academy of Orthopaedic Surgeons (AAOS), American Orthopaedic Association (AOA), and American Board of Orthopaedic Surgery (ABOS). Curriculum vitae and internet-based resources were reviewed to collect demographics, training characteristics, bibliometrics, and National Institutes of Health (NIH) research funding of contemporary presidents (1990-2020). Eighty presidents were included. Most presidents were men (97%), and 4% of presidents were non-White (3% Black and 1% Hispanic). Few had an additional graduate degree (4% MBA, 3% MS, 1% MPH, 1% PhD). Ten orthopedic surgery residency programs trained 47% of these presidents. Most had fellowship training (59%), and the top three were hand surgery (11%), pediatric orthopedics (11%), and adult reconstruction (10%). Twenty-nine presidents (36%) participated in a traveling fellowship. The mean age at appointment was 58±5 years, which was 27 years since residency graduation. The mean h-index was 36±23, resulting from 150±126 peer-reviewed manuscripts. Orthopedic surgery presidents had more peer-reviewed manuscripts (150±126) than chairs (73±81) and program directors (27±32) (P<.001). AOA presidents had the highest mean h-index (42±21) compared with AAOS (38±27) and ABOS (25±16) presidents (P=.035). Nineteen presidents had NIH funding (24%). More presidents had NIH funding in the AOA (39%) and AAOS (25%) than the ABOS (0%) (P=.007). Orthopedic surgery presidents possess high levels of scholarly output. AOA presidents had the highest h-index values and prevalence of NIH funding. Females and racial minorities remain underrepresented at the highest levels of leadership.

Comparison of Differences in Surgical Complications Between Fellowship-Trained Orthopedic Foot and Ankle Surgeons and All Other Orthopedic Surgeons Using the ABOS Database.

During the past decade, US orthopedic residency graduates have become increasingly subspecialized presumably for decreased patient complications; however, no study has examined this clinical utility for foot and ankle (F&A) surgeries among different fellowship subspecialties. Data from American Board of Orthopaedic Surgery 1999 to 2016 Part II Board Certification Examinations were used to assess patients treated by F&A fellowship-trained, trauma fellowship-trained, and all other fellowship-trained orthopedic surgeons performing ankle fracture repair. Adverse events were compared by surgical complexity and fellowship status. Factors independently associated with surgical complications were identified using a binary multivariate logistic regression. A total of 45,031 F&A cases met inclusion criteria. From 1999 to 2016, the percentage of F&A procedures performed by F&A fellowship surgeons steadily increased. Surgical complications were significantly different between fellowship trainings (F&A, 7.23%; trauma, 6.65%; and other, 7.84%). This difference became more pronounced with more complicated fracture pattern. On multivariate regression, F&A fellowship training was associated with significantly decreased likelihood of surgeon-reported complications (odds ratio, 0.83; 95% CI, 0.76-0.92; P<.001), as was trauma fellowship training (odds ratio, 0.90; 95% CI, 0.81-0.99; P=.035). Despite presumed increased complexity of cases treated by F&A fellowship-trained surgeons, these patients had significantly decreased risk of surgeon-reported surgical complications, thus highlighting the value of F&A fellowship training. In the absence of vital patient comorbidity data in the American Board of Orthopaedic Surgery database, further research must examine specific patient comorbidities and case acuity and their influence on treatments and surgical complications between fellowship-trained and other orthopedic surgeons to further illuminate the value of subspecialty training.

Academic Faculty Demonstrate Weak Agreement in Evaluating Orthopaedic Surgery Residents.

As objective metrics fade, subjective elements of orthopaedic surgery applicants carry increasing importance during recruitment. Academic orthopaedic surgeons believe they can select for high-performing orthopaedic residents. However, can they agree? The purpose of this study was (1) to analyze an academic orthopaedic surgery department to determine whether they agree on which residents performed best during residency and; (2) to correlate preresidency and intraresidency factors with postresidency evaluations of resident performance. With Institutional Review Board [IRB] approval, an orthopaedic surgery department completed surveys to evaluate residency performance for 10 years of graduated residents (2012-2022). Faculty determined (1) Post-Residency Class Rank (PRCR)-ranked from the highest (1) to lowest performing resident (5) relative to their class based on faculty perspective of performance-and (2) Rank List Score (RLS)-ranked based off the 5-point AOA SLOR used during recruitment interviews. RLS assessed how likely the department would have graduates in the program again based on residency performance. Free marginal Cohen's kappa statistics assessed faculty inter-rater agreement. Preresidency metrics (United States Medical Licensing Exam [USMLE] 1 and 2 scores, research publications, etc) were correlated with Orthopaedic In-Training Exam (OITE) scores, research productivity, American Board of Orthopaedic Surgery (ABOS) scores, and faculty-derived rankings. Linear regressions with forward variable entry (p < 0.05) were used to determine factors associated with excellent resident performance. Eighteen of 25 faculty members (72%) provided survey responses evaluating 46 residents. Faculty agreed 37% and 38% of the time for PRCR (kappa 0.26) and RLS (kappa 0.23), respectively. Step 2 score was the only preresidency factor significantly associated with PRCR (p = 0.03, r2 = 0.15) and RLS (p = 0.02, r2 = 0.3). The only intraresidency factor significantly correlated with PRCR (p = 0.002, r2 = 0.50) and RLS (p = 0.01, r2 = 0.39) was PGY-4 OITE score. An academic orthopaedic surgery department is able to come to a consensus on evaluations of residency performance relative to peers in the same year of training (PRCR) and an objective standard (RLS). Step 2 and Post-Graduate Year (PGY)-4 OITE scores were the only preresidency and intraresidency factors with significant association to higher postresidency, faculty-derived performance scores. III.

Treatment patterns of ABOS part II candidates: A decline of operative management among geriatric proximal humerus fractures over the decade (2010–2020)

BackgroundThe purpose of this study was to assess trends in ABOS part II candidate's operative management of geriatric (≥65 years) proximal humerus fractures over the 2010–2020 decade. MethodsThis retrospective database cohort study utilized the American Board of Orthopaedic Surgery (ABOS) database for candidates taking Part II of their boards. Surgical coding was reviewed and the ICD10 data was correlated to the CPT code for shoulder arthroplasty or open reduction internal fixation. We investigated the number of proximal humerus fracture operative cases per year, the percent arthroplasty used per year, the stratification of percent arthroplasty per orthopaedic fellowship subspecialty and geographic region. ResultsA total of 2,409 operative cases for proximal humerus fractures in patients 65 years of age and older were submitted by 1,420 ABOS candidates. There was a 37% reduction in operatively managed proximal humerus fractures among ABOS part II candidates between the first half of the decade (2010–2015, 263.2 +/- 13.4) and the second half of the decade (2016–2020, 166 +/- 31.2; p<.05). There also was a downward trend with a 53% reduction in percent treated with arthroplasty as compared to ORIF during those same windows (2010–2015, 34.4 +/-11.7) and (2016–2020, 16.2 +/- 6.4; p<.5). Partitioned by single fellowship training, Shoulder and Elbow (S&E) surgeons performed the highest percent arthroplasty at 25.2%, followed by Sports at 23.1% and the lowest percent arthroplasty was Trauma at 11.7%. The Southeast United States had the lowest percentage arthroplasty at 15.8% as compared to the Midwest (23.8%) and Northeast (25.8%). ConclusionDespite the rapid growth of both the elderly population and related geriatric proximal humerus fractures, ABOS candidates are treating less with surgery. There has been approximately a 37% decrease in the total number of operatively treated proximal humerus fractures between the first and second half 2010–2020 decade. When operative treatment is performed, there is a trend towards ORIF over an arthroplasty. Trauma fellowship trained surgeons are less likely to perform an arthroplasty as compared to other subspecialties. The Southeast region is least likely to perform an arthroplasty as compared to the Midwest or Northeast.

Recent Trends in Spine Topics on the Orthopaedic In-Training Examination.

The Orthopaedic In-Training Examination (OITE) is an important metric for orthopaedic residents and residency programs to gauge a resident's orthopaedic knowledge. Because the OITE is correlated with the likelihood of passing part I of the American Board of Orthopaedic Surgery, greater emphasis is being placed on the examination. However, a detailed look at the questions most likely to appear on the spine subsection of the OITE has not been done in the past decade. Digital copies of the OITEs during the years 2017 through 2021 were obtained online through the "ResStudy" program within the American Academy of Orthopaedic Surgeons Online Learning Platform. All spine-related questions were categorized into five different categories including type of spine question (knowledge-based, diagnosis, or evaluation/management), anatomical region, imaging modality provided, subject matter, and referenced journal or textbook. The total number and likelihood of each question type to appear on the OITE were defined as mean and percentage of the total number of spine questions, respectively. A total of 139 spine questions were identified on the OITE during the years 2017 to 2021. The most common type of spine questions were evaluation/management (N = 65) and knowledge-based questions. We identified lumbar (N = 45), cervical (N = 42), thoracolumbar (N = 13), and thoracic (N = 12) as the most commonly tested anatomical regions. Spinal trauma (N = 26), disk disease/disk herniation (N = 16), postoperative complications (N = 15), and scoliosis/sagittal balance (N = 15) were the most commonly tested material. Spine (N = 54) was almost two times more likely to be referenced as the source for the tested material compared with other journals or textbooks. Understanding the spine topics most likely to appear on the OITE may allow orthopaedic residents and residency programs to supplement educational objectives toward the highest yield spine topics and journals.

Early-Career Sports Medicine Surgeons Perform a Large Volume of Non-Sports Medicine Procedures: American Board of Orthopaedic Surgery (ABOS) Part-II Data Regarding Orthopaedic Surgeons Specializing in Sports Medicine.

The purpose of this study was to utilize the American Board of Orthopaedic Surgery (ABOS) Part-II Case List database to (1) define the practice patterns of sports medicine-trained ABOS Part- II Oral Examination Candidates and (2) describe the frequency and practice patterns of individuals who are dual fellowship-trained sports medicine candidates. The ABOS Part-II Case List database was utilized to define all cases submitted by 3,298 applicants indicating completion of a sports medicine fellowship between January 1, 2003, and January 1, 2020. Cases were classified by subspecialty category and case type. The frequency and practice patterns of candidates pursuing additional fellowship training (i.e., "dual fellowship-trained") were recorded. Descriptive statistical methods were used to describe the annual and overall procedure volume and candidate case mix. Trends in the relative frequency of cases performed and fellowship training patterns were determined using linear regression analysis. On average, sports medicine-trained candidates submitted 100.6 cases for review during the 6-month case collection period: 59.0 (58.6%) sports medicine/arthroscopy cases, 29.3 (29.1%) trauma/general cases, 4.5 (4.5%) adult reconstruction cases, and 7.8 (7.8%) "other" cases per candidate. Although candidates performed fewer total (r 2 = 0.84, p < 0.001) and sports medicine/arthroscopy (r 2 = 0.85, p < 0.001) cases over the study period, the proportion of sports medicine/arthroscopy cases did not change over the study period (p = 0.18). Dual fellowship training was indicated by 333 individuals (10.1%). The number of dual fellowship-trained candidates pursuing additional fellowship training in pediatrics and adult reconstruction increased over the study period, and the number of dual fellowship-trained candidates pursuing additional fellowship training in trauma decreased over the study period. Early-career sports medicine candidates are likely to perform >40% of cases outside of the sports medicine subspecialty. Sports medicine trainees are increasingly likely to pursue a second fellowship in pediatrics or adult reconstruction. Therapeutic Level III .

Unicompartmental Knee Arthroplasty Utilization among Early Career Surgeons: An Evaluation of the American Board of Orthopaedic Surgery Part-II Database.

An updated understanding of unicompartmental knee arthroplasty (UKA) utilization is needed. The purpose of this study was to evaluate temporal trends in volume and utilization of UKA among early-career surgeons and to examine the influence of fellowship training status on utilization of UKA. The American Board of Orthopaedic Surgery (ABOS) Part-II database was queried from 2010 to 2019 to identify candidates who reported ≥1 total knee arthroplasty (TKA) or UKA. Self-reported history of fellowship training experiences was recorded. "High-volume" surgeons were defined as performing ≥7 UKA over the ABOS Part-II collection period. Trends were evaluated with the Cochrane-Armitage test and generalized linear models. From 2010 to 2019, a total of 2,045 candidates (28.1%) reported ≥1 TKA, while 585 candidates (8.0%) reported ≥1 UKA. The number of candidates reporting ≥1 UKA significantly increased (p = 0.001). An increase in UKA volume was observed over the study period (p < 0.001). Rates of utilization of UKA relative to TKA did not change significantly over the study period (p = 0.11). Sixty-three (2.4%) candidates met the study definition for high-volume UKA utilization. UKA procedure volume increased among ABOS Part-II candidates over the study period; however, rates of UKA utilization relative to TKA volume remained unchanged. Increasing volume of UKA performed by early-career surgeons is likely secondary to an increased number of surgeons trained in adult reconstruction. Only 2.4% of candidates who reported performing at least one knee arthroplasty procedure met the threshold for a high-volume UKA practice. Early-career surgeons should remain conscientious of UKA volume in their practice.

American Board of Orthopaedic Surgery's Initiatives Toward Competency-Based Education.

The American Board of Orthopaedic Surgery (ABOS) is the national organization charged with defining education standards for graduate medical education in orthopaedic surgery. The purpose of this article is to describe initiatives taken by the ABOS to develop assessments of competency of residents to document their progress toward the independent practice of orthopaedic surgery and provide feedback for improved performance during training. These initiatives are called the ABOS Knowledge, Skills, and Behavior Program. Web-based assessment tools have been developed and validated to measure competence. These assessments guide resident progress through residency education and better define the competency level by the end of training. The background and rationale for these initiatives and how they serve as steps toward competency-based education in orthopaedic residency education in the United States will be reviewed with a vision of a hybrid of time and competency-based orthopaedic residency education that will remain 5 years in length, with residents assessed using standardized tools.

Arthroscopic Versus Open Rotator Cuff Repair: Fellowship-Trained Orthopaedic Surgeons Prefer Arthroscopy and Self-Report a Lower Complication Rate

PurposeTo evaluate whether fellowship training had an effect on the practice pattern and complication rates among Part II examinees of the American Board of Orthopaedic Surgery (ABOS) for rotator cuff repair (RCR) from 2007-2017.MethodsThe ABOS database was queried for arthroscopic (Current Procedural Terminology [CPT] code 29827) and open/mini-open (CPT codes: 23410, 23412) RCR performed from 2007-2017. Excluded were procedures that did not included CPT codes 29827, 23410, 23412. A comparison between arthroscopic and open/mini-open use as well as self-reported complications were assessed based on recorded fellowship training.ResultsA total of 31,907 RCR were reported over the past 10 years (2007-2017). The percentage of RCR procedures performed using arthroscopic technique vs open/mini-open varied among surgeons who completed one fellowship: Sports Medicine (92.5 % arthroscopy; 7.5 % mini/open), Shoulder & Elbow (91.3 % arthroscopy; 8.7% mini/open), and Hand & Upper Extremity (69.6 % arthroscopy; 30.4 % open). Total complication rates varied among surgeons who completed one fellowship: Sports Medicine (11.5 %), Shoulder & Elbow (13.5 %), and Hand & Upper Extremity (13.4 %). Surgeons completing one fellowship in either Sports Medicine, Shoulder & Elbow, Hand & Upper Extremity all reported significantly lower complication rates using arthroscopic over mini/open technique (P < .001).ConclusionsAmong ABOS Part II examinees completing a Sports Medicine, Shoulder and Elbow or Hand and Upper Extremity fellowship, Sports Medicine trained surgeons had significantly greater rates of performing arthroscopic over open RCR and significantly lower self-reported intraoperative complication rates.Clinical RelevanceUnderstanding the effects of fellowship training may guide mentors and future trainees.

Treatment trends in distal humerus fractures between ABOS part II candidates

PurposeThe purpose of this study was to determine how fellowship training influences the treatment of distal humerus fractures with either total elbow arthroplasty (TEA) or open reduction internal fixation (ORIF). MethodsThe American Board of Orthopaedic Surgery (ABOS) Part II Examination Database was queried for all orthopaedic surgeons who sat for the Part II examination between the years 2003-2019. Inclusion criteria were ORIF or TEA cases, selected by individual CPT codes for each procedure, and patients of at least age 65 years who sustained acute distal humerus fractures. Analysis was performed for each type of fellowship training completed, total number of procedures performed, the type of procedure performed, patient demographics, and any complications. ResultsThere were 149 TEAs and 1306 ORIFs performed for distal humerus fractures between the exam years of 2003-2019. The proportion of TEA to ORIF increased from 7.6% to 11.0%. Partitioned by fellowship training, Hand and Upper Extremity surgeons performed 69 (17.4%) TEAs and 328 (82.6%) ORIFs, Shoulder and Elbow surgeons performed 34 (29.6%) TEAs and 81 (70.4%) ORIFs, Sports Medicine surgeons performed 14 (5.1%) TEAs and 263 (94.6%) ORIFs, and Trauma surgeons performed 16 (4.2%) TEAs and 366 (95.8%) ORIFs. Hand and Upper Extremity surgeons treated the most distal humerus fractures (397, 27.3%), followed by Trauma surgeons (382, 26.3%). ConclusionOur data suggests that fellowship training does influence the surgical decision-making process for treating distal humerus fractures in elderly populations. Hand and Upper Extremity surgeons performed the greatest number of TEA for acute distal humerus fractures, followed by Shoulder and Elbow surgeons. Conversely, trauma surgeons performed the lowest proportion of TEA to ORIF. Level of EvidenceIII.

Do Orthopaedic In-Training Examination Scores Predict the Likelihood of Passing the American Board of Orthopaedic Surgery Part I Examination? An Update With 2014 to 2018 Data.

Previous research shows a correlation in performance between the Orthopaedic In-Training Examination (OITE) and the American Board of Orthopaedic Surgery (ABOS) Certifying Examination Part I; however, these studies are not current, with the most recent data from 2009. The purpose of this study was to update the relationship between the OITE and ABOS Part I scores with the five most recent nationwide cohorts of Part I scores and their corresponding OITE scores. The American Academy of Orthopaedic Surgeons provided the results for each resident taking the OITE from 2013 to 2017. The ABOS provided the results for each resident taking the Part I examination from 2014 to 2018. These two datasets were matched at the individual level and analyzed. Between 2014 and 2018, 3,502 first-time test-takers were present for the ABOS Part I Examination. A 96.6% pass rate was noted (3,383 of 3,502). A statistically significant correlation between the OITE score and ABOS Part I score was observed at all levels of training: postgraduate year (PGY) 1 r = 0.380, PGY2 r = 0.463, PGY3 r = 0.498, PGY4 r = 0.504, and PGY5 r = 0.504 (P < 0.001 for all correlations). The OITE scores continue to correlate with the ABOS scores and the pass rate for the ABOS with moderate strength correlation. However, although a correlation of the examinations exists when evaluated as a group, the predictive value of the OITE for passing the Part I examination for any specific individual is far from perfect. Individuals with PGY5 OITE percentile scores less than 10 pass the Part I examination, and individuals with PGY5 OITE percentile scores greater than 90 fail the Part I examination.

Complications of Hardware Removal.

While hardware removal may improve patient function, the procedure carries risks of unexpected outcomes. Despite being among the most commonly performed orthopaedic procedures, scant attention has been given to its complication profile. We queried the American Board of Orthopaedic Surgery (ABOS) de-identified database of Part II surgical case lists from 2013 through 2019 for American Medical Association Current Procedural Terminology (CPT) implant-removal codes (20680, 20670, 22850, 22852, 22855, 26320). Hardware removal procedures that were performed without any other concurrent procedure ("HR-only procedures") were examined for associated complications. In the 7 years analyzed, 13,089 HR-only procedures were performed, representing 2.1% (95% confidence interval [CI], 2.1% to 2.2%) of the total of 609,150 surgical procedures during that period. A complication was reported to have occurred in association with 1,256 procedures (9.6% [95% CI, 9.1% to 10.1%]), with surgical complications reported in association with 1,151 procedures (8.8% [95% CI, 8.3% to 9.3%]) and medical/anesthetic complications reported in association with 196 procedures (1.5% [95% CI, 1.3% to 1.7%]). Wound-healing delay/failure (2.1% [95% CI, 1.8% to 2.3%]) and infection (1.6% [95% CI, 1.4% to 1.8%]) were among the most commonly reported complications after HR-only procedures, but other serious events were reported as well, including unexpected reoperations (2.5% [95% CI, 2.2% to 2.7%]), unexpected readmissions (1.6% [95% CI, 1.4% to 1.8%]), continuing pain (95% CI, 1.2% [1.0% to 1.4%]), nerve injury (0.6% [95% CI, 0.4% to 0.7%]), bone fracture (0.5% [95% CI, 0.4% to 0.6%]), and life-threatening complications (0.4% [95% CI, 0.3% to 0.5%]). Hardware removal is one of the most commonly performed orthopaedic procedures and was associated with an overall complication rate of 9.6% (95% CI, 9.1% to 10.1%) in a cohort of recently trained orthopaedic surgeons in the United States. Although specific complications such as infection, refractures, and nerve damage were reported to have relatively low rates of occurrence, and associated life-threatening complications occurred rarely, surgeons and patients should be aware that hardware removal carries a definite risk.

Utilization of reverse shoulder arthroplasty for the treatment of glenohumeral arthritis among American Board of Orthopaedic Surgery (ABOS) Part II candidates, 2008-2019

BackgroundDespite advances in shoulder arthroplasty, treatment options for advanced glenohumeral osteoarthritis (GHOA) remain limited. Surgical management includes total shoulder arthroplasty (TSA), reverse total shoulder arthroplasty (RSA), and hemiarthroplasty. The rates of TSA and RSA for the treatment of GHOA in the United States has increased in recent years. Trends in shoulder arthroplasty in recently trained surgeons have not been explored. The purpose of the study was to examine the trends in arthroplasty use (TSA, RSA, and hemiarthroplasty) for primary GHOA among American Board of Orthopedic Surgeons (ABOS) Part II examinees, and to identify patterns based on geographic region or fellowship training. MethodsABOS Part II examinees with at least 1 shoulder arthroplasty in the examination years 2008-2019 were collected. Hemiarthroplasty, TSA, and RSA performed from 2007-2018 for a diagnosis of primary GHOA were included. Arthroplasty for primary or secondary diagnoses of fracture, infection, tumor, rotator cuff arthropathy or tear, revision, and non-arthroplasty procedures were excluded. Proportion and volume of cases were evaluated, with sub-analyses of geographic region and fellowship training. Univariate logistic regression determined statistical significance (P< .05). ResultsA total of 946,946 cases from 8609 ABOS Part II examinees were submitted, with 8733 shoulder arthroplasties performed. Overall, 3923 arthroplasties for primary GHOA were included (44.9% of all shoulder arthroplasties). TSA was used in 50.9% of cases. The proportion of RSA performed for primary GHOA has increased over the past 11 years, with RSA surpassing TSA as the most common procedure for primary GHOA over the last 4 years (P< .001). Hemiarthroplasty is less commonly. TSA and RSA were performed in similar proportions across regions, with the largest volume in the Midwest. Most procedures (91.5%) were completed by surgeons in sports medicine, shoulder and elbow, and those completing multiple fellowships. From 2008-2019 the number of RSA procedures performed for primary GHOA by sports medicine and shoulder and elbow surgeons has increased approximately 1100% and 800%, respectively (P< .001). ConclusionUtilization of RSA for treatment of primary GHOA by ABOS Part II examinees has increased significantly over the past twelve years. Among ABOS Part II examinees, RSA has recently surpassed TSA as the most common arthroplasty utilized for treatment of primary GHOA. Examination of early-career surgical practice allows for consideration of training influence in treatment of GHOA. As volume of shoulder arthroplasty continues to increase, trends and procedure volume have implications for clinical practice and patient outcomes.

The FAST Workstation Shows Construct Validity and Participant Endorsement

PurposeTo determine in what way the proposed simulation-based intervention (SBI) is an effective intervention for use in basic arthroscopic skills training.MethodsTwenty candidates were recruited and grouped according to experience. Performance metrics included the time to activity completion, errors made, and Global Rating Scale score. Qualitative data were collected using a structured questionnaire.ResultsPerformance on the SBI differed depending on previous arthroscopic training received. Performance on the simulator differed between groups to a statistically significant level regarding time to completion. A difference was also present between participants with no previous training and those with previous training when assessed using the Global Rating Scale. The SBI was deemed acceptable, user-friendly, and realistic. Participants practicing at the expert level believe that such an SBI would be beneficial in developing basic arthroscopic skills.ConclusionsThe results of this study provide evidence that the use of an SBI consisting of a benchtop workstation, laptop viewing platform, 30° arthroscope, and defined performance metrics can detect differences in the level of arthroscopic experience. This format of SBI has been deemed acceptable and useful to the intended user, increasing the feasibility of introducing it into surgical training.Clinical RelevanceThis study adds to the existing body of evidence supporting the potential benefits of benchtop SBIs in arthroscopic skills training. Improved performance on such an SBI may be beneficial for the purpose of basic arthroscopic skills training, and we would support the inclusion of this system in surgical training programs such as those developed by the Arthroscopy Association of North America and American Board of Orthopaedic Surgery.

Trends in Operative Treatment of Pediatric and Adolescent Forearm Fractures Among American Board of Orthopaedic Surgery Part II Candidates.

Pediatric and adolescent forearm fractures are among the most common injuries treated by orthopaedic surgeons. Recent literature shows that there has been an increased interest in operative management for these injuries. The purpose of the current study was to examine the trends in case volume, patient age, surgeon fellowship training, and postoperative complications of surgically treated pediatric forearm fractures over >15-year period of American Board of Orthopaedic Surgery (ABOS) Part II Oral Examination candidates. ABOS Part II candidates' Oral Examination Case List data from 2003 to 2019 was queried for all pediatric and adolescent (19 y of age and below) forearm fractures treated operatively. Patient demographics, fracture type, complications, and candidate fellowship type were identified for each case. Linear regression was used to delineate annual trends in patient age, complication rates, and case volume by fellowship type. Analysis of variance was performed to evaluate complication rates by fellowship type. Statistical significance for all comparative analyses was set at P-value <0.05. A total of 4178 pediatric and adolescent forearm fractures (mean age: 12.6 y; SD: 3.7 y) were treated surgically among ABOS Part II Oral Examination candidates during their 6-month collection periods from 2003 to 2019. The mean patient age decreased significantly (P<0.001) over the study timeframe, while complication rates increased (P<0.001). Pediatric fellowship-trained orthopaedic surgeons performed significantly more cases than general orthopaedic surgeons over recent years (P<0.001). No significant trends were identified between fellowship type and complication rates. The overall surgical complication rate was 17%. The complication rate of open fractures was 24%, which was significantly >15% complication rate of closed fractures (P<0.001). Fellowship-trained pediatric orthopaedic surgeons are performing an increasing number of pediatric and adolescent forearm fracture fixation when compared with other orthopaedic surgeons. The mean age of surgically managed pediatric forearm fracture patients has decreased from 2003 to 2019. There has been an increase in the rate of overall reported complications following pediatric forearm fracture surgery over recent years, without any significant association to any particular subspecialty. Future studies should evaluate the comparative effectiveness of surgical treatment of pediatric forearm fractures compared with closed management.
