Evaluation of Patient Education Materials From Large-Language Artificial Intelligence Models on Carpal Tunnel Release.

BACKGROUND: ChatGPT, an artificial intelligence technology, has the potential to be a useful patient aid, though the accuracy and appropriateness of its responses and recommendations on common hand surgical pathologies and procedures must be understood. Comparing the sources referenced and characteristics of responses from ChatGPT and an established search engine (Google) on carpal tunnel surgery will allow for an understanding of the utility of ChatGPT for patient education. METHODS: A Google search of "carpal tunnel release surgery" was performed and "frequently asked questions (FAQs)" were recorded with their answer and source. ChatGPT was then asked to provide answers to the Google FAQs. The FAQs were compared, and answer content was compared using word count, readability analyses, and content source. RESULTS: There was 40% concordance among questions asked by the programs. Google answered each question with one source per answer, whereas ChatGPT's answers were created from two sources per answer. ChatGPT's answers were significantly longer than Google's and multiple readability analysis algorithms found ChatGPT responses to be statistically significantly more difficult to read and at a higher grade level than Google's. ChatGPT always recommended "contacting your surgeon." CONCLUSION: A comparison of ChatGPT's responses to Google's FAQ responses revealed that ChatGPT's answers were more in-depth, from multiple sources, and from a higher proportion of academic Web sites. However, ChatGPT answers were found to be more difficult to understand. Further study is needed to understand if the differences in the responses between programs correlate to a difference in patient comprehension.

Intramedullary Fixation of Hand Fractures and Arthrodeses.

Intramedullary fixation has long been popular for fracture fixation in the upper extremity from the shoulder through the carpus. Recently, intramedullary fixation in the hand has gained increasing interest, specifically in the metacarpals and phalanges, corresponding with the development of improved cannulated headless screw technology. Along with the advantages of increased operative speed and less surgical dissection, which can promote rapid healing, many benefits exist, supporting their use despite some drawbacks. This article reviews the background and biomechanics of intramedullary fixation with a specific focus on cannulated headless screws, describes the application and techniques of intramedullary screw fixation in the hand, and details the associated outcomes and costs for metacarpal fractures, phalangeal fractures, and interphalangeal joint arthrodesis.

Failure of humeral shaft fixation: construct characteristics.

PURPOSE: Fixation failure following open reduction and internal fixation (ORIF) of humeral shaft fractures can be a challenging complication. We aimed to identify the modes of failure and characteristics of failed fixation constructs. METHODS: We queried our institutional database for patients > 18 years old with fixation failure after ORIF with single plate and screw constructs of humeral shaft fractures from 2006 to 2017. Demographics, fracture characteristics, fixation construct design and mode of failure were recorded. RESULTS: Twenty-three failures were identified. Mean age was 55.9 years (SD 19.2 years) with 15 (65%) women. Twelve patients (52%) had midshaft fractures; the remainder had distal-third shaft (8 pts, 35%) or proximal-third shaft (3 pts, 13%) fractures. Midshaft fractures were most commonly fixed through an anterolateral approach with plates and all non-locking screws (83%), while distal-third shaft fractures were fixed with a combination of locking and non-locking screws from a posterior approach. Distal-third shaft fractures failed by plate breakage (63%) or screw pullout (38%) and all midshaft failures occurred by screw pullout proximal (92%) or distal (8%) to the fracture. Resultant varus deformity occurred in 20 (87%) fractures. CONCLUSION: Screw pullout in midshaft fractures suggests that fixation to bone was insufficient or biomechanically disadvantageous. Varus moments contribute significantly to the failure of humeral shaft fracture ORIF. Plate breakage in distal fractures suggests high concentrations of stress over a narrow working length of constructs with inadequate plate strength. Recognizing how these constructs fail can aid proper implant selection and application for humeral shaft fracture. LEVEL OF EVIDENCE: Treatment level IV.

A 5-Year Update and Comparison of Factors Related to the Sex Diversity of Orthopaedic Residency Programs in the United States.

Female physicians have been historically underrepresented in orthopaedic surgery residencies. The purpose of this study was to determine whether sex diversity among orthopaedic residency programs and faculty is associated with an increased number of female residents matriculating into that program. In addition, we sought to analyze female resident matriculation trends in the past 5 years. Methods: The American Medical Association Fellowship and Residency Electronic Interactive Database was used to identify all allopathic orthopaedic surgery residency programs during the 2021 to 2022 academic year. The number of female residents and interns; the number of female faculty, professors, and associate professors; and the number of women in leadership positions were compared with data from the academic year 2016 to 2017. Continuous data were analyzed with independent t-tests, and significance was set at p < 0.05. Results: A total of 696 female residents (19.2%) were identified from 3,624 orthopaedic residents, an increase from 13.5% in 2016. Programs in the top quartile of female residents had 3 times the number of female residents per program when compared to other quartiles and almost double the number of female interns per program. Programs in the top quartile of female residents had a significantly greater number of female faculty per program than the lower quartiles; 5.76 vs. 4.18. Compared with 2016 to 2017, there were significant increases in female faculty per program from 2.77 to 4.54 along with female full professors from 0.274 to 0.694. These increases contribute to the overall growth in the number of women in leadership positions per program over the past 5 years to 1.01 from 0.35 (p < 0.001). Conclusion: In the past 5 years, the percentage of female residents has increased from 13.5% to 19.2%. Furthermore, women make up 22.1% of interns. Orthopaedic surgery residency programs with higher percentages of female faculty had higher numbers of female residents. By encouraging programs to promote female representation within leadership and residents, we may continue to see the gap in orthopaedic sex diversity close. Level of Evidence: III.

Interpersonal Interactions and Biases in Orthopaedic Surgery Residency: Do Experiences Differ Based on Gender?

BACKGROUND: Women residents are underrepresented in orthopaedic surgery. The causes of the deficit of women in orthopaedic surgery are multifactorial, but by identifying the perceptions of women in orthopaedic residency training and comparing them with the perceptions of men, we can improve our understanding of ways to enhance the recruitment of qualified and diverse candidates. QUESTIONS/PURPOSES: (1) What differences exist in the perceived experiences of residents identifying as women and men regarding professional, social, and personal interactions during residency training? (2) Are there differences in the percentage of women and men residents who have experienced harassment or discrimination in preresidency interviews, and are there differences in the type of harassment or discrimination experienced? METHODS: A survey was generated using Academy of Critical Care: Development, Evaluation, and Methodology guidelines. Two focus groups with seven attending orthopaedic surgeons who participate in the Collaborative Orthopaedic Education Research Group and who are experts on gender diversity in orthopaedics were held to improve survey validity. The survey included binary-response, Likert, and free-text questions on the perception of professional, social, and personal interactions held by the resident being surveyed. The questions focused on a respondent's perception of interactions with staff members, patients, resident colleagues, and attending surgeons, as well as sexual harassment. Program directors at 10 selected Accreditation Council for Graduate Medical Education (ACGME)-accredited orthopaedic residency programs that participate in the Collaborative Orthopaedic Education Research Group shared the survey with residents at their institutions. There were 95 programs in the Collaborative Orthopaedic Education Research Group at the time this survey was distributed. In this program, directors or other interested teaching faculty in orthopaedic residency programs voluntarily participate to discuss and develop quality research on resident and fellow education. These 95 programs account for 46% of the ACGME-accredited programs in the United States at the time the survey was created and distributed. The 10 residency programs had a total of 232 enrolled residents; 15% (34) identified as women. This gender distribution models the national sample of orthopaedic residents. Survey reliability was assessed by calculating the Cronbach alpha after determining the variance in each relevant (nondemographic) survey item. The final survey was found to have excellent internal reliability (alpha = 0.95). Responses from residents identifying as women and those identifying as men were compared using Fisher exact tests for all categorical data, and two-tailed independent t-tests were used for all continuous data. Differences in each survey category (professional interactions, social interactions, personal interactions, and sexual harassment in preresidency interview experiences) were calculated. RESULTS: Women reported experiencing microaggressions (left undefined to the survey respondent, but generally considered to be subtle, stunning, often automatic, and nonverbal exchanges that are "put downs") at work more frequently than men did (40% [six of 15] versus 5% [four of 74]; p < 0.001). Specifically, women perceived being interrupted (53% [eight of 15] versus 5% [four of 75]); p < 0.001) by men colleagues, called by their first name (67% [10 of 15] versus 4% [3 of 72]; p < 0.001), and given administrative tasks (27% [four of 15] versus 1% [one of 75]; p = 0.004) more often than men. More women than men perceived that patients (33% [five of 15] versus 0 of 74 [0%]; p < 0.001) and hospital staff (27% [four of 15] versus 7% [five of 74]; p = 0.01) respected their opinion less than that of men. More women than men perceived that group humor negatively targeted their gender (47% [seven of 15] versus 1% [one of 75]; p < 0.001) and that criticism of their surgical skill was based on their gender rather than their ability (33% [five of 15] versus 5% [four of 78]; p = 0.005). In residency or subinternship interviews, 20% of women reported experiencing sexual harassment as defined by a listing of known types of harassment in the question stem, compared with 0% of men (p = 0.004). Women reported harassment in the form of verbal remarks of a sexual nature and obscene images in the workplace, whereas men did not report any form of harassment during interviews. CONCLUSION: These findings suggest that the greatest discrepancies in the perceived experiences of women and men residents lie in professional interactions, and women residents are more likely to experience sexual harassment and disparaging humor than men residents. CLINICAL RELEVANCE: Addressing these discrepancies, particularly in the professional setting, will help to create a more inclusive work environment and attract more women to orthopaedic surgery. Annual distribution of the survey used in this study by program directors to residents in their programs can help to identify discrepant perceptions that, coupled with the collection of objective data, can be targeted for improvement.

The effect of COVID-19 on adult traumatic orthopedic injuries: a database study.

PURPOSE: This study compares orthopedic injuries, procedures, and hospital outcomes of patients presenting to trauma centers in Pennsylvania before and during the COVID-19 pandemic. METHODS: A retrospective review of adult patients presenting to hospitals with Pennsylvania Trauma Systems Foundation (PTSF) designations was performed. All patients 18 years of age and older who presented with orthopedic injuries were included. Demographic information, injury and hospital stay details, and mortality were reviewed. Data were compared between the cohorts of patients presenting during April 2020 (COVID cohort) and April 2017, April 2018, and April 2019 (pre-COVID cohort). RESULTS: Overall, 14,858 patients were reviewed, and 9427 patients were included in this study. There were fewer orthopedic injuries (4868 vs. 6603 yearly mean) in the COVID cohort which led to fewer procedures (1763 vs. 2329 yearly mean). The COVID cohort had a significantly shorter mean hospital length of stay compared to the pre-COVID cohort (4.7 days versus 5.2 days, p = 0.01). A higher mortality rate was seen in the COVID cohort (n = 115, 6.1%) compared to the pre-COVID cohort (n = 305, 4.0%; p < 0.01). CONCLUSION: The characteristics of orthopedic injuries sustained by patients presenting to trauma centers during the COVID pandemic were not different from prior to the pandemic. However, there were decreases in the number of orthopedic injuries and procedures accompanied by a 50% increase in mortality seen in these patients during the pandemic. Resources should be appropriately marshalled to prevent rises in-hospital mortality for patients with orthopedic trauma treated during a pandemic. LEVEL OF EVIDENCE: Level III.

Biomechanical Comparison of Dual and Posterior Locking Plates in an Ex Vivo Comminuted Olecranon Fracture Model.

PURPOSE: Comminuted olecranon fractures are commonly fixed with posterior locking plates (PLPs). Though biomechanically validated, this method comes with risks of symptomatic implant prominence and wound breakdown. Dual locking plates (DLPs) placed on the medial and lateral surfaces of the olecranon theoretically avoid these risks and allow for fixation of proximal fracture fragments in multiple planes. A biomechanical comparison of DLP and PLP fixation would help to validate the use of DLPs in comminuted olecranon fractures. METHODS: Seven matched pairs of cadaveric upper extremities were evaluated with quantitative computed tomography scans to evaluate bone mineral density (BMD). Osteotomies simulating comminuted olecranon fractures (Mayo Type IIB) were created and the specimens were fixed either with variable angle PLPs or variable angle DLPs. The specimens were then cyclically loaded and loaded to failure. The ultimate strength, fracture displacement, and mechanism of failure were recorded and compared across groups. The correlation between BMD and ultimate strength was analyzed. RESULTS: The mean total BMD was 0.79 g/cm2 (SD, 0.14 g/cm2). No specimen failed during cyclic testing. Five of 7 PLP specimens and 5 of 7 DLP specimens failed by fracture through the proximal screws though in different planes (sagittal vs axial splits, respectively). The mean ultimate strengths of the PLP (1077 N [SD, 462 N]) and DLP (1241 N [SD, 506 N]) groups were similar. There was a linear relationship between ultimate strength and BMD (R2 = 0.33). CONCLUSION: Dual locking plates display biomechanical properties that suggest that they can be used in the fixation of comminuted olecranon fractures. Catastrophic failure of the fixation constructs occurs around stress risers at the proximal screws rather than due to displacement at the fracture itself. CLINICAL RELEVANCE: Dual locking plate constructs can be considered for use in the fixation of comminuted olecranon fractures.

Relevance of Diagnosed Depression and Antidepressants to PROMIS Depression Scores Among Hand Surgical Patients.

PURPOSE: We aimed to test the utility of screening for depressive symptoms in the hand surgical office focusing on chances of heightened depressive symptoms in patients with no history of diagnosed depression and by quantifying ongoing depressive symptoms among patients diagnosed with depression accounting for antidepressant use. The clinical importance of this study was predicated on the documented negative association between depressive symptoms and hand surgical outcomes. METHODS: This cross-sectional study analyzed 351 patients presenting to a tertiary hand center between April 21, 2016, and November 22, 2017. Adult patients completed self-administered Patient-Reported Outcomes Measurement Information System (PROMIS) Depression computer adaptive tests at registration. Health records were examined for a past medical history of diagnosed depression and whether patients reported current use of prescription antidepressants. Mean PROMIS Depression scores were compared by analysis of variance (groups: no diagnosed depression, depression without medication, depression with medication). Four points represented a clinically relevant difference in PROMIS Depression scores between groups and Depression scores greater than 59.9 were categorized as having heightened depressive symptoms. RESULTS: Sixty-two patients (18%) had been diagnosed with depression. Thirty-four of these patients (55%) reported taking antidepressant medications. The PROMIS Depression scores indicated greater current depressive symptoms among patients with a history of diagnosed depression when not taking antidepressants (11 points worse than unaffected) and also among patients taking antidepressants (7 points worse than unaffected). Heightened depressive symptoms were detected in all groups but were more prevalent among those diagnosed with depression (36% with no medication, 29% with antidepressant medication) compared with unaffected patients (7%). CONCLUSIONS: Depression screening for heightened depressive symptoms identifies 1 in 14 patients without diagnosed depression and 1 in 3 patients diagnosed with depression as having currently heightened depressive symptoms. Hand surgeons can use PROMIS Depression screening in all patients and using this to guide referrals for depression treatment to ameliorate one confounder of hand surgical outcomes. TYPE OF STUDY/LEVEL OF EVIDENCE: Symptom prevalence study II.

Orthopaedic Surgery Faculty: An Evaluation of Gender and Racial Diversity Compared with Other Specialties.

BACKGROUND: The American Academy of Orthopaedic Surgeons has adopted the strategic goal of evolving its culture and governance to become more strategic, innovative, and diverse. Given the charge to increase diversity, a focus on assessing and increasing diversity at the faculty level may help this cause. However, an analysis of gender and racial diversity among orthopaedic faculty has not been performed. The purpose of this study was to evaluate faculty appointments for underrepresented minority (URM) and female orthopaedic surgeons. We also aim to draw comparisons between orthopaedic surgery and other specialties. METHODS: Data on gender, race, and faculty rank (clinical instructor, assistant professor, associate professor, and professor) of academic faculty for 18 specialties from 1997 to 2017 were obtained from the Association of American Medical Colleges (AAMC) Faculty Roster. Assistant professors were designated as junior faculty, whereas associate professor and professor were considered senior faculty. URMs were defined using the AAMC definition-groups having lower representation than in the general population. Regression analysis was used to evaluate and compare the change over time and to compare the change across different specialties. RESULTS: Over the 20-year study period, the number of female faculty increased (8.8% pts) but represents a lower proportion than other specialties (13.9% pts) (p = 0.029). Female orthopaedic senior faculty grew slower (7.3% pts) than other specialties (14.7% pts) (p < 0.001). There was no difference in the growth of URM faculty positions (2.0% pts) compared with all other specialties (2.4% pts) (p = 0.165). The proportion of orthopaedic URM senior faculty increased less (0.5% pts) than other specialties (2.5% pts) (p < 0.001), whereas more orthopaedic URM junior faculty were added than other specialties (2.2% pts) (p = 0.012). CONCLUSIONS: Although orthopaedic surgery has increased the representation of female and URM faculty members, it continues to lag behind other specialties. In addition, fewer female and URM orthopaedic faculty members obtained senior faculty status than other specialties. To address the differences seen in faculty diversity, a concerted effort should be made to recruit and promote more diverse faculty, given similar qualifications and capabilities. LEVEL OF EVIDENCE: Prognostic Level IV.

Characteristics and Publication Rates for Podium Presentations at National Hand Surgery Meetings from 2007 to 2012.

The purpose of this study was to evaluate and compare the research presented at the annual meetings of the American Society for Surgery of the Hand (ASSH) and the American Association for Hand Surgery (AAHS). Podium presentation data were extracted from the abstract books of the annual meetings of the ASSH and AAHS from 2007 to 2012. Corresponding publications were identified using searchable online publication databases and an algorithm linking authorship and content. The majority of research was clinical and the most common topics were trauma, degenerative conditions, and biomechanics. The most common body region of interest was the wrist/forearm. ASSH podium presentations were of a stronger level of evidence and were more likely to be published. The mean times to publication for research presented at the ASSH and AAHS meetings were 16.7 and 16.4 months, respectively. Presentations from each society were subsequently published at higher proportions in their affiliated journals. Furthermore, in comparison to AAHS presentations, a significantly larger proportion of research presented at the ASSH meetings was published in the Journal of Bone and Joint Surgery , while a larger proportion of AAHS presentations were published in Plastic and Reconstructive Surgery and Microsurgery .

Analysis of the Sports Medicine Section of the Orthopaedic In-Training Examination: Improvements in Levels of Evidence and Question Taxonomy Over a 12-Year Period.

There has been a recent shift within the orthopedic literature to publish articles with higher levels of evidence. In this investigation, the trends in question taxonomy and the levels of evidence of the references for sports medicine questions on the Orthopaedic In-Training Examination (OITE) during a 12-year period were evaluated. Sports medicine questions were obtained from the OITEs administered between 2005 and 2007 and between 2014 and 2016. The taxonomy of each question was characterized, and levels of evidence for all references were assigned using American Academy of Orthopaedic Surgeons guidelines. Question taxonomy and article levels of evidence from 2005 to 2007 were compared with those from 2014 to 2016. Sports medicine questions comprised 8% of the OITEs in both examination groups. The questions from 2014 to 2016 had a higher mean taxonomic level (2.26 vs 1.52, P=.0001) and a greater proportion of studies with high levels of evidence (levels 1 and 2) (21% vs 10%, P=.027). However, references with low levels of evidence or nonprimary resources made up 82.2% and 68.5% of the total references on the older and more recent examinations, respectively. References from 2014 to 2016 were, on average, 2 years older than those from earlier examinations. This study indicated that sports medicine questions on recent OITEs cite references of higher levels of evidence and contain higher taxonomic question structure than examinations 10 to 12 years ago. However, the majority of questions still cite articles with low levels of evidence or nonprimary sources. These findings can be used to guide resident education and continue improvements in the selection of references for questions on the Sports Medicine section of the OITE.

Evaluation of Spanish Language Proficiency and Resources Available in Academic Pediatric Orthopaedic Centers.

INTRODUCTION: Given the rapidly increasing population of Spanish-speaking patients in the United States, medical providers must have the capability to effectively communicate both with pediatric patients and their caregivers. The purpose of this study was to query the Spanish language proficiency of pediatric orthopaedic surgeons, assess the educational resources available to Spanish-speaking patients and their families, and identify the barriers to care at academic pediatric orthopaedic centers. METHODS: The Web sites of medical centers within the United States that have pediatric orthopaedic surgery fellowships recognized by the Pediatric Orthopaedic Society of North America (POSNA) were accessed. Web sites were investigated for a health library as well as the availability of interpreter services. Profiles of attending surgeons within each Pediatric Orthopaedic Department were evaluated for evidence of Spanish proficiency as well as educational qualifications. Centers were contacted by phone to determine if the resources and physicians who could converse in Spanish were different than what was readily available online and if automated instructions in Spanish or a person who could converse in Spanish were available. RESULTS: Forty-six centers with 44 fellowship programs were identified. The profiles of 12 of 334 (3.6%) surgeons who completed pediatric orthopaedic fellowships indicated Spanish proficiency. Seventeen physicians (5.1%) were identified as proficient in Spanish after phone calls. Thirty-eight pediatric orthopaedic centers (82.6%) noted interpreter service availability online, although services varied from around-the-clock availability of live interpreters to interpreter phones. When contacted by phone, 45 of 46 centers (97.8%) confirmed the availability of any interpreter service for both inpatient and outpatient settings. Sixteen centers (34.8%) had online information on orthopaedic conditions or surgical care translated into Spanish. Twenty centers (43.5%) did not have automated phone messages in Spanish or live operators that spoke Spanish. CONCLUSIONS: There is a scarcity of surgical providers in pediatric orthopaedic centers proficient in Spanish, demonstrating a large discrepancy with the growing Hispanic population. Interpreter services are widely available, although there is variability in the services provided. Considerable barriers exist to Spanish-speaking patients who attempt to access care by phone or online.

Distal Radius Fractures in the Athlete.

Although the technical details of distal radius fracture fixation in athletes are largely similar to the general population, the issues surrounding the injury, desire to return to sport, and rehabilitation require specialized attention. Athletes are generally healthy, with a drive to recover and must balance the risk of long-term consequences of returning to play too early with the potential loss of scholarship, salary, or opportunities for advancement. Outcomes after nonoperative and operative treatment of distal radius fractures are generally excellent in athletes and return to the same level of sport occurs in most patients.

Perceptions of the Educational and Institutional Impact of the Orthopaedic Fellowship Interview Process.

INTRODUCTION: The time spent applying and interviewing for an orthopaedic fellowship has notable financial, educational, and workflow consequences on both residents and their respective residency programs. The purpose of this study was to assess the perceptions regarding the fellowship interview process to suggest changes that could be implemented. METHODS: Mixed-response questionnaires were sent to orthopaedic surgery residency program directors (PDs) and PGY-4 to PGY-6 residents at the 164 accredited allopathic orthopaedic surgery residency programs in the United States (August 2017). RESULTS: Significantly more PDs believed that time away for fellowship interviews negatively affected resident education compared with residents (68% versus 25%, 48 of 65 versus 28 of 113; P < 0.001). About half of all PDs and residents noted a specific amount of time granted for interviews (range, 3 to 20 days). Seventy-one percent of residents included in this study would favor regionally coordinated interview dates. CONCLUSIONS: Orthopaedic surgery residents and PDs perceive differences in the impact of the fellowship interview process on resident education and means for improvement of the process. Two-tiered or regionally coordinated interviews are favored as changes that could be implemented.

Global variability in orthopedic surgery training.

Medical and orthopedic training varies throughout the world. The pathways to achieve competency in orthopedic surgery in other countries differ greatly from those in the United States. This review summarizes international educational requirements and training pathways involved in the educational development of orthopedic surgeons. Understanding the differences in training around the world offers comparative opportunities which may lead to the improvement in education, training, and competency of individuals providing orthopedic care.

What Patient-related Factors are Associated with an Increased Risk of Surgery in Patients with Stenosing Tenosynovitis? A Prospective Study.

BACKGROUND: Numerous patient-related risk factors have been identified as contributors to patient progression to operative treatment of stenosing tenosynovitis (STS). Identifying patients most at risk of undergoing surgery after receiving a corticosteroid injection would enable health care providers to identify patients most likely to benefit from nonsurgical treatment. QUESTIONS/PURPOSES: (1) What proportion of prospectively enrolled patients with a new diagnosis of STS did not require further intervention after a first, second, or third injection when offered up to three corticosteroid injections? (2) Which identifiable risk factors present at the initial evaluation in patients with STS are associated with the patient opting for surgical release after a trial of one, two, or three corticosteroid injections? METHODS: One hundred ninety-six patients with a presumed diagnosis of STS were evaluated between March 2014 and June 2015, and 160 patients with 186 affected fingers were prospectively enrolled after a new diagnosis of STS was made during the study period. STS was diagnosed by assessing for tenderness at the A1 pulley, passive or active triggering, and the absence of other confounding diagnoses. Only the affected finger received a corticosteroid injection, and these patients were followed up during the study period. Patients were followed for 2 years, and 135 of the 160 patients (84%) completed the final followup. Patients with recurrent symptoms were treated with up to three corticosteroid injections before undergoing A1 pulley release, although patients could elect to undergo surgery at any time. Bivariate comparisons and a multivariate logistic regression analysis were used for independent fingers (one per participant) to identify independent variables associated with progression to surgery after injection. The time between treatments (between injection and subsequent injection or between injection and surgery) for those with recurrent symptoms was also calculated. Information collected from the last time the patient could be contacted was carried forward in the analysis for all 160 patients. RESULTS: No further treatment was sought after the first, second, and third injections by 81 of 160 (51%), 16 of 45 (37%), and three of 10 patients (30%), respectively; 100 of 160 patients (63%) did not pursue further intervention. After the first, second, and third injections, 36 of 160 patients (23%), 17 of 43 patients (40%), and seven of 10 of patients, respectively, did not respond to treatment. After controlling for 21 potentially confounding patient- and disease-related variables, we found that only two risk factors at the initial presentation were protective against eventual progression to surgery: osteoarthritis in the fingers (odds ratio [OR], 0.26 [95% CI, 0.085-0.786]; p = 0.017) and a longer duration of symptoms (OR, 0.58 [95% CI, 0.38-0.89]; p = 0.012). There was no association between progression to surgery and hand dominance, finger type (thumb or other), whether the patient had diabetes, or whether the affected finger was one of multiple affected fingers. Patients who presented again for intervention (injection or surgery) did so at a mean of 153 ± 94 days. CONCLUSIONS: Although patients should be counseled that their risk of progressing to surgery after an initial corticosteroid injection is lower than for subsequently administered injections for recurrent symptoms, nonoperative treatment should not be bypassed for patients with any of the studied risk factors. LEVEL OF EVIDENCE: Level II, therapeutic study.

Utility of Prolotherapy for Upper Extremity Pathology.

Prolotherapy is a method of treatment of painful musculoskeletal conditions whereby a sclerosing agent is injected into an area of tendinosis or osteoarthritis to strengthen and repair painful connective tissue. It is a safe, effective, and relatively inexpensive nonsurgical treatment modality. This article provides a history of prolotherapy, discusses its proposed mechanisms of action, and provides a review of the existing literature on prolotherapy as a treatment for upper extremity pathologies, specifically, hand osteoarthritis, lateral epicondylitis, and rotator cuff disease.

Evaluation of Orthopaedic Interest Groups in American Medical Schools.

BACKGROUND: Orthopaedic interest groups (OIGs) are student-run organizations that can provide medical students with early exposure to orthopaedic surgery. OIGs can serve as venues for musculoskeletal education, clinical experiences, and mentorship to students with otherwise limited access to orthopaedics. The purpose of this study was to evaluate the prevalence and opportunities offered by OIGs. METHODS: The websites of all allopathic medical schools in the United States were evaluated. Each website was examined for an established OIG and any pertinent information regarding shadowing, research opportunities, lectures, workshops, or opportunities to interact with residents. OIGs were categorized based on the number and type of offerings provided to their members. RESULTS: Of the 141 allopathic medical school websites evaluated, 108 (108/141, 76%) had evidence of an orthopaedic interest group. Sixty-nine (69/108, 64%) of these schools described the opportunities provided. The most common opportunities were clinical skills workshops (41/69, 59%), lectures (32/69, 46%), and opportunities to interact with current residents (30/69, 43%). The majority of OIGs (39/69, 57%) offered fewer than half of the possible opportunities and only 6 groups (9%) offered all five opportunities. CONCLUSION: The majority of allopathic medical schools in the United States have an OIG; however, the opportunities provided to orthopaedic interest group members vary widely from institution to institution.

Geographic Trends in the Orthopedic Surgery Residency Match.

BACKGROUND: Residency program location may be an important factor for orthopedic surgery residency applicants. More than half of residents locate their practice near the site of their training, and surgical specialties (eg, otolaryngology, plastic surgery, and general surgery) have shown geographic patterns in their residency matches. OBJECTIVE: We analyzed geographic trends in the orthopedic surgery Match. METHODS: Hometown, undergraduate institution, and medical school "preresidency locations" of all allopathic, nonmilitary, orthopedic surgery residents were recorded from program websites for the 2015-2016 academic year. Program and preresidency locations were coded according to state and US census division. Statistical analysis was used to investigate associations between residency program locations and preresidency locations. RESULTS: Of 2662 residents in the study, 1220 of 2614 (47%), 536 of 1329 (40%), and 308 of 744 (41%) matched into the same division as their medical school, undergraduate institution, and hometown, respectively. There were significant differences among divisions (P < .001). Also, 817 of 2662 (31%), 319 of 1329 (24%), and 200 of 770 (26%) residents matched in the same state as their medical school, undergraduate institution, and hometown, respectively, with significant differences between states for medical school (P < .0001) and undergraduate institution (P < .0001), but not hometown (P = .22). Overall, 21% of residents (538 of 2612) matched at the program affiliated with their medical school. CONCLUSIONS: There is an association among hometown, undergraduate institution, and medical school for the training program location in which orthopedic surgery residents match, with variability in locations matched at state and census division levels.

Cost-Effective Management of Stenosing Tenosynovitis.

PURPOSE: Stenosing tenosynovitis (STS) is a common condition treated by hand surgeons. Limited evidence exists to support the nonsurgical management of STS. The purpose of this study was to prospectively evaluate a cohort of patients with STS, and to determine the strategy for treating patients with this condition that is most cost effective in terms of dollars reimbursed by payers. METHODS: Prospective data were collected on patients diagnosed with STS between March 2014 and September 2014. All patients were initially treated with a corticosteroid injection. Patients with persistent symptoms were given the option of injection or surgery. A maximum of 3 injections were offered. All patients were evaluated every 6 months through office appointments or phone calls. A cost analysis was performed in our cohort using actual reimbursement rates for injections, initial and established patient visits, and facility and physician fees for surgery, using the reimbursement rates from the 6 payers covering this patient cohort. Cost savings were calculated based on offering 1, 2, and 3 injections. RESULTS: Eighty-eight digits in 82 patients were followed for an average of 21.9 months (range, 18.7-22.7 mo) after an initial corticosteroid injection. Thirty-five digits went on to surgical release, whereas 53 digits were treated nonsurgically. Had all patients initially undergone surgery, the cost would have totaled $169,088.98 ($1,921 per digit). Offering up to 3 injections yielded a potential savings of $72,730 ($826 per digit) or 43% of the total cost. For the 33 patients who underwent more than 1 injection, offering a second injection yielded potential savings of $15,956 ($484 per digit, 22.7%), and for the 7 patients presenting a third time, a third injection saved $1,986 ($283 per digit, 14.5%). CONCLUSIONS: Based on the data from our cohort, the efficient way to treat STS in terms of health care dollars spent is to offer up to 3 injections before surgical release. The first injection had the highest component of cost savings, at $826 per digit. TYPE OF STUDY/LEVEL OF EVIDENCE: Economic/Decision Analysis III.
