Formal patient complaints and malpractice events involving orthopedic trauma surgeons (OTSs) can have substantial career implications. Our purpose was to analyze formal patient complaints, risk events, and malpractice events against OTSs during a 10-year period. We reviewed all formal patient complaints within our institution's patient advocacy database involving 9 fellowship-trained OTSs throughout a decade. Complaints were categorized using the Patient Complaint Analysis System. Potential risk and malpractice events involving the OTSs were recorded. A control group of all patients seen by the surgeons during the study period was created. Demographics between patients with complaints and the control group were analyzed, as were malpractice, risk, and complaint rates between the surgeons. Of 33,770 patients, 136 filed a formal complaint (0.40%). There were 29 malpractice claims and 2 malpractice lawsuits. The care and treatment domain accounted for the highest percentage of complaints (36%), followed by the access and availability domain (26%). Results of the logistic regression analysis indicated that private insurance (odds ratio, 1.58) and operative treatment (odds ratio, 3.65) were significantly associated with complaints. Despite statistically significant differences in the rates of complaint and risk events between surgeons, malpractice events did not differ. The rate of patient complaints within a large orthopedic trauma practice during a 10-year period was 0.40%. Patients with private insurance and those treated operatively were more likely to file a complaint. Whereas complaint rates among surgeons varied, there was no significant difference in the rate of malpractice events. Understanding patient complaint rates and categorizations may allow surgeons to target areas for improvement. [ Orthopedics . 2023;46(2):121–127.]

To assess the interrater reliability of the CTS-6 for examiners with varying levels of clinical expertise. We also aimed to analyze this instrument's sensitivity (Sn) and specificity (Sp), using the CTS-6 score obtained by a hand surgeon as a reference standard.Three examining groups consisting of medical students, occupational hand therapists, and hand surgeons examined a consecutive series of patients in an academic upper-extremity clinic. A total of 3 examiners (1 from each group) recorded a CTS-6 score for each patient. The examiners were blinded to the scores from the other groups. The interrater reliability was determined between the groups with respect to the diagnosis of CTS and the individual CTS-6 components. Sn and Sp were calculated for each of the groups using the CTS-6 obtained by the hand surgeons as the reference standard.Two hundred seven patients were included. For the diagnosis of CTS (CTS-6 score of 12 or greater as determined by a hand surgeon), there was substantial agreement between the 3 groups (Fleiss kappa 0.73; 95% CI [0.65 -0.82]; P.05). For individual CTS-6 components, the agreement between the groups was highest for assessing subjective numbness and lowest for assessing a Tinel sign (Fleiss kappa of 0.77 and 0.49, respectively). The Sn/Sp for diagnosing CTS was 87%/91% for the medical student group and 81%/95% for the occupational hand therapist group.The CTS-6 can be reliably used as a screening and diagnostic tool for CTS by clinicians with a variety of experience levels and without specific fellowship training in upper-extremity surgery.Diagnostic I.

Purpose To define and compare gender diversity among faculty and trainees within hand surgery fellowship programs. Methods We determined the gender of each program director for all orthopedic residency and fellowship programs. Specific to hand fellowship programs, we determined the gender of the fellowship director and all faculty members for all plastic surgery and orthopedic hand fellowship programs. Lists of prior hand surgery fellows from 2014 to 2019 were obtained from official program websites or program coordinators. The gender distribution of the hand fellowship program directors and faculty was compared to the prior fellows. Results Hand surgery fellowship programs had the second highest percentage of female fellowship directors (13%) behind orthopedic oncology (27%). Within hand surgery, 614 total faculty positions were identified, and 15% were female. Of the 89 hand surgery programs evaluated, 36 (60%) had at least 1 female faculty member. For the 849 prior fellows identified, 213 (25%) were female, and 79% of programs had at least 1 female fellow. Hand programs led by a female director did not have a higher percentage of prior female fellows compared to programs led by a male director (26% vs 25%). Programs with a female fellowship director were as likely to have had at least 1 prior female fellow compared to programs with a male fellowship director. Conclusions For orthopedic subspecialties, hand surgery fellowship programs had the second highest percentage of female fellowship directors (13%). While mentorship plays an important role in surgical education, hand fellowship programs with female faculty did not appear to attract more female fellows or faculty. Clinical relevance Hand fellowship programs should recognize that the presence of female faculty may not be a primary factor in fellowship selection for female applicants, and further study into recruiting qualified female candidates should be encouraged.

Purpose To determine whether demographic differences exist among editors, reviewers, and authors in The Journal of Hand Surgery (JHS). We aimed to test the null hypothesis that there would be no difference among these 3 groups with respect to gender, geographic location, academic productivity, and financial relationships with industry. Methods Editors, reviewers, and physician authors were identified for 2018 JHS. Gender and geographic location were recorded for each person. We used the Scopus database to determine the Hirsch index (h-index) as well as the number of publications and citations for members of each group. Industry payment information was obtained using the Open Payments Web site. Results The editor group contained 20% women compared with the author group (17% women). Authors (59%) were less likely to be from the United States compared with editors (91%) and reviewers (88%). Editors were found to have a higher h-index (16) compared with reviewers (14) and authors (12). Authors demonstrated significantly higher mean total payments from industry ($41,738) compared with editors ($13,712) and reviewers ($20,457). Conclusions In 2018, there appeared to be an even distribution with respect to gender among editors, authors and reviewers in the JHS. International editors and reviewers are relatively under-represented compared to authors. Whereas editors and reviewers demonstrated higher h-indices compared with authors, JHS authors had significantly higher mean total payments in the Open Payments database. Clinical relevance Defining demographics, academic productivity, and conflicts of interest for journal editors, reviewers, and authors may aid in identifying potential sources of both author and peer review bias.

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

Background: Our purpose was to describe structural and morphological features of the median nerve and carpal tunnel on magnetic resonance imaging (MRI) studies obtained before, immediately after, 6 weeks after, and 6 years after endoscopic carpal tunnel release (ECTR). Methods: In this prospective cohort study, 9 patients with a diagnosis of carpal tunnel syndrome (CTS) underwent ECTR. Standardized MRI studies were obtained before ECTR, immediately after ECTR, and 6 weeks and 6 years after surgery. Structural and morphological features of the median nerve and carpal tunnel were measured and assessed for each study with comparisons made between each time point. Results: All 9 patients had complete symptom resolution postoperatively. On the immediate postoperative MRI, there was a discrete gap in the transverse carpal ligament in all patients. There was retinacular regrowth noted at 6 weeks in all cases. The median nerve cross-sectional area and the anterior-posterior dimension of the carpal tunnel at the level of the hamate increased immediately after surgery and these changes were maintained at 6 years. Conclusions: We defined structural and morphological changes on MRI for the median nerve and carpal tunnel in patients with continued symptom resolution 6 years after ECTR. Changes in median nerve and carpal tunnel morphology that occur immediately after surgery remain unchanged at mid-term follow-up in asymptomatic patients. Established imaging criteria for CTS may not apply to postoperative patients. Magnetic resonance imaging appears to be of limited clinical utility in the workup of persistent or recurrent CTS.

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

Although there has been a recent emphasis on standardized resident assessments within Accrediation Council for Graduate Medical Education programs, assessments of faculty teaching performance and effectiveness are less frequent. Our purpose was to compare the teaching performance of orthopaedic surgery faculty receiving compensation for time spent teaching with faculty without compensation.For this prospective investigation, we collected anonymous resident reviews of 23 orthopaedic faculty within a rural, academic orthopaedic residency program over 2 academic years. Performance reviews of the faculty used a validated assessment of clinical teaching effectiveness with nine domains (faculty knowledge, organization, enthusiasm, rapport, involvement in learning experiences, feedback, clinical skill, accessibility, and overall effectiveness). A composite teaching effectiveness score was determined by adding each of the scores from the individual domains. We compared reviews for faculty members with and without compensation for time spent teaching.A total of 202 performance reviews for 23 orthopaedic faculty were analyzed. Most of the faculty were male (91%), and 61% received compensation for teaching. No demographic differences were observed between the two faculty groups. Notable differences between the groups were noted in three domains: enthusiasm, ability to establish rapport as well as direction, and feedback. Faculty compensated for teaching demonstrated a markedly higher composite teaching effectiveness score than those without compensation.These data suggest that orthopaedic faculty compensated for teaching responsibilities provide a better educational experience for resident trainees compared with faculty without compensation for teaching. Future studies should aim to assess varying compensation models for teaching responsibilities across different departments.

Background: Defining an intraoperative radiographic view to best determine the radial styloid screw position in locked volar plating of distal radius fractures may improve fixation and aid in decreasing cortical penetration and implant complication. We used a cadaveric model to demonstrate a reproducible, oblique radiographic view to identify the radial styloid screw position. Methods: Nine fresh-frozen elbow-to-fingertip cadavers were used for this study. A 2.4-mm variable angle volar distal radius locking plate was applied to the distal radius. A Kirschner wire (K-wire) was inserted into the radial styloid through the plate. Placement of the K-wire through the tip of the styloid at the cortical edge was confirmed through a separate radial incision. A second K-wire was placed through the radius shaft into the ulna to aid in angular measurements. Live fluoroscopic imaging was used as the forearm was brought from full 90° of supination toward neutral. Once the K-wire was abutting the cortical edge, rotation ceased, and a goniometer was used to measure the angle of forearm rotation. This was repeated for a total of 3 repetitions on each specimen. Results: The average angle of supination best depicting the position of the radial styloid screw was 68.5° (range = 64.3°-70.5°). Conclusions: Radial styloid screw fixation in locked volar plating of distal radius fractures increases the ultimate strength to failure, but screw penetration and tendon irritation can occur. The 70° supinated oblique intraoperative view provides the most accurate evaluation of the position of the radial styloid screw.

Purpose To assess the use of preoperative, dynamic ultrasound to predict ulnar nerve instability following in situ decompression for cubital tunnel syndrome . Methods Prior to undergoing in situ decompression, 43 consecutive patients underwent dynamic ultrasound to assess the stability of the ulnar nerve during elbow flexion . The dynamic ultrasound findings were compared with the intraoperative assessment of nerve stability following in situ decompression. Results The preoperative dynamic ultrasound agreed with intraoperative findings in 38 of 43 patients (88%). Physical examination of ulnar nerve stability agreed with the intraoperative findings in 5 of 43 patients (12%). For the 5 of 43 cases in which the dynamic ultrasound did not correlate with the degree of ulnar nerve stability after in situ decompression, dynamic ultrasound overestimated the degree of ulnar nerve stability in 4 cases. Conclusions Preoperative dynamic ultrasound can be used to accurately predict the degree of ulnar nerve instability following in situ decompression. Type of study/level of evidence Diagnostic II.

INTRODUCTION Our purpose was to define and categorize patient complaints within a hand surgery practice over a 10-year period. In addition, we aimed to define surgeon and patient factors associated with formal complaints. METHODS All patients who filed a complaint with our institution's patient advocacy service against six hand surgeons in an academic practice over a 10-year period were recorded and categorized using the Patient Complaint Analysis System. A control group consisting of all patients seen by the surgeons during the study period was created. Demographic differences between the complaint and control groups were analyzed, as were complaint rates between surgeons. We obtained the number of malpractice events involving each of the surgeons. RESULTS During the 10-year study period, 73 of 36,010 unique patients seen (0.20%) filed a complaint. Care and treatment category comprised the highest percentage of complaint designations (30%), followed by access and availability (23%). Forty-three patients (59%) who filed complaints were treated surgically. Patients with a complaint had a significantly higher percentage of mental, behavioral, or neurodevelopmental disorders compared with controls (55% versus 42%, P = 0.03). The complaint rate (total complaints/total new patients seen) ranged between 0.09% and 0.29% for the six surgeons, and these results were not statistically significant. DISCUSSION Within an academic hand and upper extremity surgery practice, the rate of patient complaints is 0.20% or approximately one complaint for every 500 new patients seen. Most patient complaints are categorized within the care and treatment domain. Underlying mental health conditions are associated with more frequent complaints. Communication issues appear to represent a modifiable area that hand surgeons can improve to help mitigate potential complaints. Understanding both the frequency and types of patient complaints may allow hand surgeons to recognize areas for improvement and avoid potential exposure to malpractice litigation. LEVEL OF EVIDENCE Prognostic level III (case-control).

Purpose We sought to determine surgeon-pathologist agreement with respect to distinguishing between a previously undivided transverse carpal ligament (TCL) and scar during revision carpal tunnel release (CTR). Additionally, we aimed to describe the histologic findings of the TCL and flexor tenosynovium during revision CTR. Methods All patients undergoing revision CTR for persistent or recurrent CTS by a single surgeon between 2013 and 2019 were included. An intraoperative assessment was made as to the presence of scar versus a previously undivided TCL by the surgeon. Two pathology specimens (1 consisting of flexor retinaculum and 1 consisting of tenosynovium) were sent for histopathological analysis with hematoxylin-eosin staining. The pathologist’s assessment of the flexor retinaculum specimen was categorized as either “ligamentous” if a previously undivided TCL was identified or “nonligamentous” if scar or any other tissue was identified. The surgeon’s intraoperative assessment served as the reference standard when comparing the histologic assessment. Results A total of 40 patients underwent 46 revision CTRs. The histologic assessment agreed with the surgeon’s intraoperative assessment of a previously undivided TCL versus a scar in 30 of 46 (65%) cases. In 12 of 46 (26%) revision cases, the surgeon determined that there was a previously undivided TCL. In these 12 cases, the pathologist identified a ligament 17% of the time. Conclusions Surgeon-pathologist agreement is low with respect to determining previously undivided TCLs versus nonligamentous tissue in the setting of revision CTR. The results of this investigation suggest that pathologists (with limited clinical information) have difficulty confirming the clinical diagnosis of persistent CTS with previously unreleased TCL when using routine hematoxylin-eosin staining. Routine biopsy of the TCL during revision CTR may be of limited clinical utility, as it does not alter the diagnosis or management in these cases. Type of study/level of evidence Diagnostic III.

BACKGROUND: Maladaptive coping strategies can lead to less functional improvement after upper-extremity surgery. It remains uncertain how well surgeons can recognize signs of less effective coping strategies in patients in the absence of formalized questionnaires. Our purpose is to determine if the “Handshake Test” can be used to identify patients with less effective coping strategies. We hypothesize that a simple physical examination finding (a refusal or inability to shake hands) is associated with higher pain level, maladaptive coping strategies and decreased functional status. METHODS: We prospectively analyzed 246 consecutive new patients presenting to one of three surgeons with atraumatic upper-extremity conditions. Patients completed a pain scale (NPRS) and PROMIS instruments including Self-Efficacy (SE) for Managing Symptoms, Pain Interference (PI) and Upper Extremity (UE). Each surgeon recorded a refusal to shake hands as part of a normal greeting, referred to as a “positive Handshake Test”. RESULTS: 200 patients (81%) patients completed all outcome measures and were included in our analysis. 8% demonstrated a positive Handshake Test. Patients with a positive Handshake Test were more likely to use tobacco; otherwise baseline demographics were similar between the two groups. Patients with a positive Handshake Test demonstrated higher pain scores (NPRS and PROMIS PI), lower levels of self-efficacy and worse self-reported functional status on the PROMIS UE. CONCLUSIONS: For patients with atraumatic upper-extremity conditions, those with a positive Handshake Test report higher pain levels, lower self-efficacy, and decreased self-reported functional status than patients who can perform a handshake. This simple test can aid in identifying patients with less effective coping strategies, allowing surgeons to guide patients towards interventions to improve both illness behavior and functional outcomes.

Purpose To define self-reported WALANT use among American Society for Surgery of the Hand (ASSH) members. We aimed to define surgeon and practice demographics relative to WALANT use and identify potential barriers for WALANT implementation. Methods An anonymous multiple-choice survey was electronically distributed to all active ASSH members. Incomplete surveys were included in the final analysis. Surgeons were asked to provide reasons for not performing WALANT, which were categorized based on general themes. We compared practice and surgeon demographic information relative to WALANT use. Results Of 3,826 ASSH members, 869 responded (23%). A total of 79% of respondents had performed at least one WALANT procedure; 62% currently incorporated WALANT into their practice. Hospital-owned outpatient surgery centers were the most common location for WALANT procedures (31%). Canadian surgeons were more likely to use WALANT, compared with US and international surgeons. Surgeons with fewer years in practice and higher-volume surgeons were more likely to use WALANT. There was no statistically significant association between either practice or income structure and WALANT use. For carpal tunnel release (CTR), 13% did not offer patients WALANT, whereas 43% offered WALANT to all patients. Moreover, 51% of surgeons reported that anesthesia staff was required to be present for WALANT cases at their institution. In determining reasons for not using WALANT, 16% reported that they preferred a tourniquet for visualization. Only 2% had concerns regarding epinephrine use in the hand. Conclusions The results of this survey illustrate current WALANT use among ASSH members and defines the demographics of those employing WALANT. Lack of familiarity with WALANT and an acceptance of the use of epinephrine in the hand has increased from prior ASSH surveys. Lack of familiarity with the technique, concerns regarding operating room efficiency, and patient preferences remain considerable barriers to more widespread adoption of WALANT procedures.

Purpose To define technology and social media use among rural upper-extremity patients. In addition, we aimed to assess how patients use social media in relation to health care and their willingness to participate in telemedicine programs. Methods An anonymous multiple-choice written survey was administered to 550 upper-extremity patients at 4 rural outreach clinics. Demographic information was obtained, as was social media use, habits and interests. We compared both users and nonusers of social media to define demographic differences between these groups. Results A total of 412 patients completed surveys and were included in our analysis (75%); 225 reported using social media (55%). Of the respondents, 67% had a high school education or less and 60% reported an income of less than $50,000/y with an unemployment rate of 58%. In addition, 28% reported not owning a smartphone and 20% lacked home Internet access. Multivariable regression demonstrated that age, female sex, and home Internet access were all independently associated with increased social media use. Facebook was the most frequently used social media platform. Moreover, 42% were interested in telemedicine and social media users were significantly more likely to be interested in telemedicine programs compared with non-social media users. Conclusions Within a population of rural and economically disadvantaged upper-extremity patients, 55% currently use social media; 32% used these platforms to research health conditions. Whereas younger female patients with home Internet access were more likely to use social media, older patients were more likely to use these platforms to research health conditions. Clinical relevance As more health information moves on-line and as telemedicine programs continue to evolve, some rural upper-extremity patients may still have technological barriers in the form of smartphone and computer ownership as well as a lack of home Internet access.

Purpose To compare surgeon and patient assessment of upper extremity functional status at the time of initial consultation. We hypothesized that surgeons and patients demonstrate low levels of agreement with respect to assessing pain scores, functional status, and self-efficacy. Methods One hundred forty-three consecutive new patients were evaluated by 1 of 5 fellowship-trained upper extremity surgeons. Patients completed a Numeric Pain Rating Scale as well as the Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE), Pain Interference (PI), and Self-Efficacy (SE) instruments. Surgeons provided their own estimates of patient function on each questionnaire at the conclusion of the visit and were blinded to the results of the patient-reported outcome measures (PROMs) for the duration of the study. Estimation errors, which represent the absolute value of the difference between the patient’s actual score and the surgeon’s estimated score on each questionnaire, were calculated for each questionnaire. Results As a group, surgeons assumed that the PROMIS UE and SE scores were higher than the patients’ actual scores and assumed that patients had lower PROMIS PI scores than were actually reported. Mean estimation errors for all PROMIS instruments were greater than 10 points and larger than the SD for these instruments in the general population. Conclusions Upper extremity surgeons demonstrate difficulty assessing their patient’s self-reported functional status, pain interference, and level of self-efficacy during initial consultations. Clinical relevance Although formalized PROMs are infrequently administered in orthopedic clinics, increased utilization of these questionnaires would allow for a more accurate baseline functional assessment. When evaluating new patients in the outpatient clinic, surgeons should recognize the potential limitations of their assessments of patient-reported function.

Metacarpal fractures account for up to 18% of all upper extremity fractures seen below the elbow. The small finger sustains the most fractures followed by the ring, long, thumb, and index fingers. Stable metacarpal fractures are traditionally treated with immobilization. There is no consensus on how to treat unstable metacarpal fractures. Ideally the fixation utilized should be stable enough to allow for mobility as early as 3 weeks to reduce the risk of stiffness. There are many treatment methods that each have their own advantages and disadvantages. This chapter presents several cases showcasing different fixation methods for various fracture patterns.

The operative and non-operative treatment of phalangeal fractures can be challenging. While fracture non-union is uncommon, adhesions and stiffness are common complications. There are three key principles to treating hand fractures: reduction within acceptable parameters, stable maintenance of reduction, and early mobilization. While brief immobilization post-operatively is common practice, more than 3 weeks of immobilization leads to stiffness. We present several illustrative cases to demonstrate common strategies and pitfalls to avoid when treating these fractures.

Background: Farming remains the most dangerous occupation in the United States and upper extremity (UE) injuries occur frequently in agricultural accidents. The purpose of this study is to describe the injury mechanisms, severity, and health care costs of UE injuries resulting from agricultural accidents and to compare patients with and without injuries to the UE. Methods: We performed a 6-year retrospective review of our level I trauma center registry from January 2006 to May 2013, identifying all patients injured in an agricultural accident. Data collection included baseline demographics, injury type and mechanism, costs and treatment. Patients with UE injuries were compared with those without UE injuries. Results: Ninety-six of 273 patients (35%) sustained an UE injury with fractures of the phalanx and radius/ulna occurring most frequently. Patients with UE injuries were more likely to be injured from table saws ( P = .0003) and farm machinery ( P < .0001). Twenty-one percent with UE injuries sustained a mangled extremity. Patients with UE injuries were more likely to require surgery (68% vs 36%, P < .0001) and were more likely to be readmitted (17% vs 5%, P = .0007) with risk factors for readmission including age >18 years, falls from height, and surgery. Mean hospital charges were $95 147. Conclusions: Patients sustaining agricultural UE injuries have longer lengths of stay and more frequently require surgery despite similar hospital charges compared with non-UE injured patients. Hospital readmissions occur frequently for patients with UE injuries. Understanding injury mechanisms and the epidemiology of these potentially devastating and costly injuries may help guide agricultural injury prevention programs.

Background: The purpose of this cadaveric study is to evaluate the trajectory of percutaneous transverse Kirschner wire (K-wire) placement for fifth metacarpal fractures relative to the sagittal profile of the fifth metacarpal in order to develop a targeting strategy for the treatment of fifth metacarpal fractures. Methods: Using 12 unmatched fresh human upper limbs, we evaluated the trajectory of percutaneous transverse K-wire placement relative to the sagittal profile of the fifth metacarpal in order to develop a targeting strategy for treatment of fifth metacarpal fractures. The midpoint of the small and ring finger metacarpals in the sagittal plane was identified at 3 points. At each point, a K-wire was inserted from the small finger metacarpal into the midpoint of the ring finger metacarpal (“center-center” position). Results: The angle of the transverse K-wire relative to the table needed to achieve a center-center position averaged 20.8°, 18.9°, and 16.7° for the proximal diaphysis, middiaphysis, and the collateral recess, respectively. Approximately 80% of transversely placed K-wires obtained purchase in the long finger metacarpal. Conclusions: These results can serve as a guide to help surgeons in the accurate placement of percutaneous K-wires for small finger metacarpal fractures and may aid in surgeon training.

While hand injuries occur frequently in the athletic population, sagittal band ruptures, boutonniere deformities, and pulley ruptures are infrequently encountered. These injuries represent diagnostic challenges and can result in significant impairment. Early recognition with appropriate treatment is necessary to maximize recovery and minimize return to athletic competition. This review will focus on the underlying mechanism, pathophysiology of injury, diagnosis, and treatment of each of these injuries.With respect to sagittal band ruptures, boutonniere deformities, and pulley ruptures, the recent literature has been limited in scope. For sagittal band injuries, current efforts have focused on alternative techniques for sagittal band reconstruction. Little progress has been made in recent years with respect to boutonniere injuries in the athletic population; prevention of fixed deformities remains the backbone of treatment. The exact contribution from individual and combined pulley injuries in the creation of bowstringing remains controversial. Recent anatomical studies have failed to definitively answer the question of what degree of rupture is necessary to create symptomatic bowstringing. Favorable outcomes, with respect to both preventing bowstringing and returning to full athletic participation, have been newly reported following pulley reconstruction in rock climbers. Due to the infrequent nature of sagittal band ruptures, boutonniere deformities, and pulley ruptures, current treatment is mostly guided by historically established methods, limited case series, and case reports. Nonsurgical treatment remains the mainstay for most injuries and, if employed early, often precludes the need for surgery. Further anatomical and clinical research, including outcome studies, is necessary in guiding treatment algorithms.

Smartphones, computers, and Internet access continue to become more available to both patients and physicians. As these technologies develop with respect to health care, opportunities for telemedicine visits continue to emerge. The purpose of this review article was to analyze the current use and potential applications of telemedicine in hand and upper-extremity surgery. Although the literature pertaining to the use of telemedicine in hand surgery is limited, videoconferencing visits may provide benefits to patients. Particularly in rural and underserved regions, patients can decrease considerable travel burdens. Potential applications for this technology include remote inpatient and emergency room consultations, outpatient clinic visits, and postoperative care. There are unique considerations with respect to confidentiality and security. As with any new technology, it is important to analyze safety concerns. Future randomized, prospective investigations are necessary to define the economic implications of telemedicine programs more clearly within hand and upper-extremity surgery.

Background: The purpose of this investigation was to compare pain control and patient satisfaction for conventional postoperative opioid analgesia and nonopioid multimodal analgesia after elective open or endoscopic carpal tunnel release (CTR). Methods: As part of a randomized, prospective study, patients undergoing primary, elective CTR were randomized to receive either postoperative opioids or nonopioid medications as part of a multimodal pain control strategy. Patients currently taking opioids were excluded. Patients completed a postoperative pain journal and completed the shortened version of the Disabilities of the Arm, Shoulder, and Hand Questionnaire (QuickDASH), Boston Carpal Tunnel Questionnaire, Numeric Pain Rating Scale (NPRS), and satisfaction ratings at their 2-week visit. Results: A total of 68 patients were included. Preoperatively, there were no statistically significant differences between the 2 groups with respect to pain scores, coping skills, or carpal tunnel symptoms. At 2 weeks postoperatively, patients in the nonopioid group had lower average NPRS and QuickDASH scores. Patients who took opioids consumed an average of 5 pills. No patient randomized to the nonopioid group required any opioids. Patients in the nonopioid group demonstrated lower early postoperative NPRS scores. Patient satisfaction with their pain control regimen and outcome was not significantly different between the 2 groups at any time point. Conclusions: Nonopioid medications as part of a perioperative pain control strategy demonstrate improved pain scores compared with opioid medications with similar patient satisfaction and functional outcomes. Considering the risks associated with the use of opioid analgesics, we recommend against prescribing opioids after CTR, particularly in patients not currently taking narcotic medications.

Purpose Despite the associations between workhours, fatigue and motor vehicle accidents, driving abilities for residents post-call have been infrequently analysed. Our purpose was to compare orthopaedic surgery resident performance on a driving simulator after a night of call compared with their baseline. Study design All residents from a single orthopaedic programme were asked to complete baseline and post-call driving simulator assessments and surveys. The primary outcome measure was brake reaction time (BRT) and secondary outcome measures included lane variance, speed variance and accidents on the driving simulator. Results All 19 orthopaedic residents agreed to participate. Compared with the baseline assessment, residents demonstrated significantly higher levels of sleepiness on the Stanford Sleepiness Scale post-call (1.6 vs 3.4; p Conclusions These data suggest that for orthopaedic residents, driving simulator performance does not appear to be worse after a single night of call compared with baseline. Future collaborative, multicentre investigations on post-call driving safety that incorporate different call types and frequencies are necessary to better define the impact of post-call fatigue on driving performance. Recognising that motor vehicle accidents remain the leading cause of death for people under the age of 30 years, these continued areas of study are necessary to truly establish a culture of resident safety.

Background: We aimed to identify risk factors for recurrence of trigger digit following corticosteroid injection. Methods: A retrospective review identified patients 18 years and older who presented to a single fellowship-trained hand surgeon with a symptomatic trigger digit during a 1-year period. Baseline demographic data were recorded. Patients with persistent trigger digit after a single injection were offered a second injection. Patients refusing a second injection were excluded from our analysis. Patients with persistent symptoms after 2 injections were offered surgery. For patients with diabetes mellitus, additional information regarding method of disease control and hemoglobin A1clevel was recorded. Results: The overall success of corticosteroid injection was 84% with 16% of patients requiring surgical release. Of the 240 patients successfully treated with injection, 99 (41%) required a second injection. Injections resulted in persistent triggering in 15% of patients with diabetes and 17% of patients without diabetes. A multivariate regression analysis revealed that the 2 strongest risk factors for requiring surgical release were patient age and patients whose fourth digit of the right hand was injected. Diabetes was not a risk factor for persistent triggering after corticosteroid injection. Conclusions: Our findings can be used to counsel patients prior to their initial injection and suggest that patients with diabetes can be managed with corticosteroid injection with equal efficacy compared with patients without diabetes.

Background: Although analyses of the Orthopaedic In-Training Examination (OITE) subspecialty content domains have been performed, few studies have analyzed the levels of evidence (LoEs) for journal articles used as references to create OITE questions. We present an analysis of reference characteristics and question taxonomy for the hand surgery content domain on the OITE. We aim to determine whether level of evidence (LoE) for hand surgery questions have increased over a 15-year period. Methods: All questions and references in the hand surgery content domain on the OITE from 1995-1997 and 2010-2012 were reviewed. The taxonomic classification was determined for each question. Publication characteristics were defined for each reference, and each primary journal article was assigned a LoE. Results: A total of 129 questions containing 222 references met inclusion criteria: 76 questions from 1995-1997 and 53 from 2010-2012. The Journal of Hand Surgery American and European Volumes, Journal of Bone and Joint Surgery American and British Volumes, and the Journal of the American Academy of Orthopaedic Surgeons were the most frequently cited journals overall. Recent examinations were more likely to have Buckwalter T3 complex clinical management questions. There was a statically significant increase in the LoE used to create hand questions on the 2010-2012 compared with the 1995-1997 OITE. Conclusions: Primary journal articles cited on the hand surgery content domain of the OITE frequently included recent publications from both general and subspecialty journals. More recent examination questions appear to test clinical management scenarios. LoE for hand questions has increased over a 15-year period. Our results can be used as a guide to help prepare orthopedic residents for the OITE.

Objective In the era of evidence-based medicine, understanding study design and levels of evidence (LoE) criteria is an important component of resident education and aids practicing surgeons in making informed clinical decisions. The purpose of this study is to analyze the ability of orthopedic residents to accurately determine LoE criteria for published articles compared with medical students. Design Basic science article. Setting Geisinger Medical Center (Danville, PA), tertiary referral center. Participants Overall, 25 U.S. orthopedic residents and 15 4th year medical students interviewing for a residency position in orthopedic surgery voluntarily participated and provided baseline demographic information. A total of 15 articles from the American Volume of Journal of Bone and Joint Surgery were identified. Study participants were provided with the article title, the abstract, and the complete methods section. The assigned LoE designation was withheld and access to the LoE criteria used by Journal of Bone and Joint Surgery was provided. Each participant was assigned a study type and LoE designation for each article. Results There were more correct responses regarding the article type (67%) than for LoE designation (39%). For LoE, the intraclass correlation coefficient was 0.30. The percentage of correct responses for article type and LoE increased with more years of training (p = 0.005 and p=0.002). Although residents had a higher proportion of correct LoE responses overall than medical students, this difference did not reach statistical significance (42% vs. 35%, p=0.07). Conclusions Although improvements in accurately determining both article type and LoE were seen among residents with increasing years of training, residents were unable to demonstrate a statistically significant improvement for determining LoE or article type when compared with medical students. Strategies to improve resident understanding of LoE guidelines need to be incorporated into orthopedic residencies, especially when considering the increased emphasis on evidence-based medicine.

Background: The purpose of this investigation is to compare the radiographic and intraoperative assessment of scaphotrapezoid (ST) joint arthritis in patients with end-stage carpometacarpal (CMC) arthritis of the thumb base. We aim to define the incidence of ST arthritis in this population and determine whether radiographic features such as lunate morphology, dorsal intercalated segment instability (DISI), and scapholunate (SL) diastasis are associated with the incidence of ST arthritis. Methods: We retrospectively reviewed consecutive patients with end-stage CMC arthritis of the thumb treated operatively with trapeziectomy. Preoperative wrist radiographs were reviewed, and the presence of ST arthritis was determined using the Sodha classification. Lunate morphology, DISI, and SL diastasis were noted. Intraoperative grading of ST arthritis was assessed using a modified Brown classification. The specificity and sensitivity of radiographic assessment was compared with the gold standard of intraoperative direct visualization. Results: In total, 302 thumbs met inclusion criteria. End-stage ST joint arthritis determined by intraoperative visual inspection was noted in 31% of cases. No radiographic or demographic variables were found to be risk factors for ST arthritis. Plain radiographs were 47% sensitive and 94% specific in their ability to detect end-stage ST joint arthritis. Conclusions: We report a 31% incidence of end-stage ST joint arthritis in surgically treated patients with CMC arthritis based on visual inspection which is lower than previous literature. Wrist radiographs demonstrate a 47% sensitivity and 94% specificity in predicting end-stage ST joint arthritis. It is imperative to directly visualize the ST joint after trapeziectomy, as radiographs demonstrate poor sensitivity.

As the use of cement remains prevalent in orthopedic surgery, so do concerns over the safety of its active ingredient, methyl methacrylate (MMA). The Occupational Health and Safety Agency (OSHA) limits the airborne exposure to 100 parts per million (ppm) averaged over an 8 hour period. We measured MMA exposure to operating room personnel during simulated total hip arthroplasty (THA), antibiotic bead fabrication and simulated spill of MMA. Cumulative and peak exposures during simulated THA and antibiotic bead fabrication did not exceed OSHA limits of 100ppm. Vacuum mixing and greater distance from the vapor source reduced measured MMA exposure. Spilled MMA led to prolonged and elevated MMA levels. MMA levels returned to a negligible level in all scenarios by 20 minutes after mixing.

Objective The purpose of this study was to determine if the levels of evidence for primary journal articles used as references for musculoskeletal trauma questions on the Orthopaedic In-Training Examination (OITE) have increased over a 15-year period. Design Basic science article. Setting Geisinger Medical Center (Danville, PA), tertiary referral center. Participants All 329 questions in the musculoskeletal trauma content domain on the OITE from 1995 to 1997 and 2010 to 2012 were reviewed. Baseline characteristics for each question and each reference were recorded. References were categorized as a textbook, a journal review article, an instructional course lecture, or a primary journal article. For each primary journal article, the level of evidence for the article was determined in accordance with the American Academy of Orthopaedic Surgeons Levels of Evidence Guidelines. Results The level of evidence used for primary journal articles demonstrated a statistically significant increase from 1995 to 1997 to 2010 to 2012. Overall, 27% of primary journal articles cited on the 1995 to 1997 OITEs were level I, II, or III studies, increasing to 43% during the 2010 to 2012 period (p = 0.04). The Buckwalter classification for the OITE questions changed significantly between the 2 periods, with questions from 2010 to 2012 including more T1 questions (25% vs 39%) and fewer T3 questions (46% vs 39%, p=0.016). The Journal of Bone and Joint Surgery and the Journal of Orthopaedic Trauma were the most frequently cited journals overall. Conclusions The levels of evidence for primary journal articles cited on the OITE for questions within the musculoskeletal trauma content domain have increased between 1995 and 2012. Our analysis can be used as a guide to help examinees prepare for musculoskeletal trauma questions on the OITE and as an aid in core curriculum development.

Purpose To determine with magnetic resonance imaging (MRI) the morphologic changes in the carpal tunnel and median nerve 3 months after endoscopic carpal tunnel release (ECTR). Methods We enrolled patients who had complete resolution of numbness and pain by 6 weeks after ECTR. Patients who met these inclusion criteria received an MRI at 3 months after surgery. Images were analyzed to determine whether median nerve morphology changes and discrete gap or separation of the flexor retinaculum could be appreciated on MRI. Results There were 17 patients screened and 15 met the inclusion criteria. Three-month MRI in all patients demonstrated changes in the flexor retinaculum over the median nerve. In all 15 patients, a distinct gap or separation in the fibers of the flexor retinaculum overlying the median nerve could not be appreciated. Median nerve width-to-height ratios at the level of the pisiform and at the hook of the hamate were 2.4 and 2.1, respectively. Median nerve cross-sectional area was 14.1 at the pisiform and 13.3 at the hook of the hamate. Conclusions MRI of patients 3 months after successful ECTR does not demonstrate a discrete gap or separation in the flexor retinaculum overlying the median nerve but may be useful for evaluating median nerve morphology. Type of study/level of evidence Diagnostic II.

Background The foot and ankle (FA) content domain is a component of the orthopaedic in-training examination (OITE). Levels of evidence (LoE) have been infrequently studied on the OITE. The purpose of this study is to determine if LoE for primary journal articles referenced for FA questions increased over a 15-year period. We also aim to determine if reference characteristics and question taxonomy have changed during this period. Methods All 132 questions and 261 references in the FA content domain from 1995 to 1997 and from 2010 to 2012 were included. We defined the characteristics of each reference and taxonomy of each question. Every primary journal article was assigned a LoE based on American Academy of Orthopaedic Surgeons (AAOS) guidelines. Results Foot & Ankle International ( FAI ) was the most frequently cited journal. The change in the distribution of the Buckwalter classifications was statistically significant (p = 0.0286) with an increase in the number of clinical management questions. There were more level I studies on the 2010 to 2012 OITE (p = 0.0478) 6/54 (11%) of questions on the 2010 to 2012 OITE cited level I or II evidence compared with 3/78 (4%) on the 1995 to 1997 examinations (p = 0.1035). Conclusions There is a trend toward improved LoE for journal articles within the FA content domain on the OITE over a 15-year period, particularly when analyzing the increase in level I studies. FAI is the most frequently cited journal and questions increasingly test clinical management concepts. Clinical Relevance Our results can be used to help improve resident self-study and suggest that reviewing recent FAI articles may aid OITE preparation. Level of Evidence Basic Science

The radiologist serves as an indispensable consultant for those patients with wrist pain, by determining the causes of the pain and severity of the injury, helping to determine treatment options, and providing preoperative guidance for surgery, if planned. This article reviews normal anatomic variants and potential danger areas encountered by the radiologist when interpreting magnetic resonance imaging of the wrist.

Purpose The purpose of this study was to determine whether use of a lateral meniscal interposition allograft combined with proximal row carpectomy would reduce the peak joint contact pressures and increase the contact area when compared with proximal row carpectomy alone. Methods Six cadaver wrists were cyclically moved through flexion–extension and radioulnar deviation ranges of motion. Joint contact pressure was measured with the carpus intact, after proximal row carpectomy, and after insertion of a lateral meniscal allograft. Contact pressure data were also collected with the wrist in 5 static positions. Results Proximal row carpectomy caused statistically greater peak pressures and smaller contact areas when compared with the intact wrist. Insertion of the allograft statistically restored the pressures and areas to that observed in the intact wrist. Conclusions These results support the clinical trial of a lateral meniscal interposition allograft in patients with contraindications for proximal row carpectomy, such as pre-existing arthritis in the capitate head or lunate facet of the radius.

BACKGROUND Elastic stable intramedullary nailing (ESIN) is an effective means of fixation for unstable, pediatric forearm shaft fractures with the benefit of smaller incisions, less soft tissue manipulation, and ease of removal. This study was designed to evaluate the incidence of and risk factors for extensor pollicis longus (EPL) rupture after fixation of pediatric radial shaft fractures with ESIN. METHODS A retrospective review of all patients younger than 19 years who had a repair of a forearm fracture with flexible intramedullary nailing between 2006 and 2011 was performed. Nineteen consecutive patients were identified from the electronic medical record. All patients were treated with a titanium elastic nailing system using a dorsal approach to the radius. The patients were followed postoperatively for at least 2 years, and all fractures healed. An extensive chart review assessing for persistent pain, EPL function, and risk factors for EPL rupture was performed. Implants were removed in all but 1 patient. RESULTS Seventeen records were available for review. Fourteen (82%) were male, and the mean age at time of fracture was 10 years old (range, 5 to 14 y). Follow-up averaged 5.5 years (range, 2.9 to 7.8 y). The mean weight was 32.7 kg for males and 50.6 kg for females corresponding to the 61st and 60th percentile respectively of weight-for-age (range, 8th to 99.9th percentile). Hardware was removed in all but 1 case, and the median time from surgery to hardware removal was 21 weeks (range, 8 to 63). Three of the 17 patients (18%) experienced rupture of the EPL. Two were treated with additional surgery following hardware removal, and one was untreated due to patient preference. None of the 17 patients (including those with rupture) had independent risk factors for tendon rupture: inflammatory arthritis, diabetes, or prior steroid use. Time to removal, patient age, and percentile of weight-for-age did not correlate with EPL rupture. CONCLUSIONS Although ESIN of pediatric forearm shaft fractures has gained acceptance as a treatment option, our series of 17 patients revealed an 18% rate of EPL rupture. With this small patient cohort, no patient characteristics proved to be significant risk factors for predicting tendon rupture. However, awareness should be raised for an increased risk of EPL rupture with this fixation method. LEVEL OF EVIDENCE Level IV-Therapeutic.

Purpose Standard 0.58 mg (0.25 mL) collagenase Clostridium histolyticum (CCH) preparations result in unused CCH that is often discarded. Our purpose was to assess the results on Dupuytren contractures affecting both the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints in the same digit utilizing an injection containing the maximum CCH volume that can be withdrawn from a single vial. Methods A consecutive series of patients with MCP and PIP cords in the same digit received a single treatment with 2 injections totaling 0.30 mL distributed between the MCP and the PIP cords and underwent manipulation approximately 24 hours later. Reduction in contracture, clinical success, and complications were assessed 30 days after manipulation. Results Thirty-one patients (34 digits) had a mean preinjection flexion contracture of 50° at the MCP joint and 53° at the PIP joint. Clinical success (reduction in joint contracture to 0°–5° of full extension 30-days postmanipulation) was noted in 65% of MCP cords and 38% of PIP joint cords. We had a 24% incidence of skin tears, which correlated with the degree of preinjection contracture. Conclusions For Dupuytren contractures involving the MCP and PIP joints in the same digit, distributing the maximum amount of CCH that can be withdrawn from a single vial provides efficacy at both joints that is similar to that reported in previously published series, with a comparable complication rate. Utilizing excess CCH typically discarded may provide cost savings. Type of study/level of evidence Therapeutic IV.

Background To train surgeons effectively, it is important to understand how they are learning. The Kolb Learning Style Inventory (LSI) is based on the theory of experiential learning, which divides the learning cycle into 4 stages: active experimentation (AE), abstract conceptualization (AC), concrete experience, and reflective observation. The purpose of this investigation was to assess the learning styles of orthopedic residents, faculty, and applicants at an east-coast residency program. Methods A total of 90 Kolb LSI, Version 3.1 surveys, and demographic questionnaires were distributed to all residency applicants, residents, and faculty at an academic program. Data collected included age, sex, type of medical school (MD or DO), foreign medical graduate status, and either year since college graduation, postgraduate year level (residents only), or years since completion of residency (faculty only). Seventy-one completed Kolb LSI surveys (14 residents, 14 faculty members, and 43 applicants) were recorded and analyzed for statistical significance. Results The most prevalent learning style among all participants was converging (53.5%), followed by accommodating (18.3%), diverging (18.3%), and assimilating (9.9%) (p = 0.13). The applicant and resident groups demonstrated a high tendency toward AE followed by AC. The faculty group demonstrated a high tendency toward AC followed by AE. None of the 24 subjects who were 26 years or under had assimilating learning styles, in significant contrast to the 12% of 27- to 30-year-olds and 18% of 31 and older group (p Conclusions The majority of applicants, residents, and faculty in the orthopedic residency program were "convergers." The converging learning style involves problem solving and decision making, with the practical application of ideas and the use of hypothetical-deductive reasoning. Learning through AE decreased with age, whereas learning through AC increased.

Purpose To determine whether patients with diabetes mellitus (DM) are at greater risk for developing postoperative trigger digits (TD) after carpal tunnel release (CTR) compared with patients without diabetes. Methods A retrospective review of our electronic medical records identified all patients who had undergone CTR by a single hand fellowship–trained surgeon from September 2007 through May 2012. For patients with DM, additional information regarding method of disease control and hemoglobin A1c (HbA1c) level was recorded. We recorded HbA1c levels 3 months before and 3 months after CTR. The location and time to development of postoperative, new-onset TD were recorded for each case. Statistical testing included chi-square or Student t test and multivariate logistic regression analysis. Results Of the 1,217 CTRs, 214 had DM. Of the 1,003 CTRs in cases without DM, 3% developed TD within 6 months of CTR and 4% within 1 year of CTR, compared with 8% and 10%, respectively, for diabetic cases. A multivariate regression analysis revealed DM as a significant risk factor for developing TD after CTR at 6 and 12 months. We found no significant association between HbA1c level at the time of CTR and the likelihood of developing TD. Conclusions The incidence of TD after CTR was higher in the diabetic population compared with a nondiabetic cohort. The presence of DM rather than its severity was the most important factor for developing TD. Preoperative counseling for patients with DM undergoing CTR may alert them to the possibility of developing TD. Type of study/level of evidence Prognostic IV.

Multiple techniques with good outcomes have been described for sagittal band reconstruction. We describe 2 cases of sagittal band reconstruction using an anomalous slip of the extensor tendon to the middle finger. This anomalous slip can be a resource for surgical reconstruction that can add stability to primary sagittal band repair.
