If enough force is applied in a wrist ligament injury, a perilunate dislocation may occur. Physicians can readily make the diagnosis, but the injury may be missed in the initial evaluation. With prompt recognition and intervention, the incidence of permanent disability may be lessened. Acute carpal tunnel syndrome may accompany perilunate injuries and frank dislocations. The scapholunate and lunotriquetral ligaments confer significant structural stability and help maintain the anatomical relationships of the carpal bones; when they are compromised, structural integrity is lost. Visual inspection is critical to the physical examination. Neurovascular status should be determined and documented. Radiographic evaluation is recommended for all hand injuries. All perilunate dislocations first need to be closed reduced, followed by surgical treatment. [ABSTRACT FROM AUTHOR]

Radial head and neck fractures are common and at times require operative fixation. No consensus exists on the ideal fixation construct for unstable radial neck fractures. Using 7 fresh frozen cadaveric radii, radial neck fractures were created 2 cm from the articular surface. The fractures were stabilized with 5 different commonly used constructs: crossed Kwires; a 2.4-mm T-plate using screws in the head (T-plate and nonlocked screw construct); aT-plate using a screw and locked buttress pin in the head (T-plate and locked buttress pin construct); a T-plate with an interfragmentary screw from the shaft retrograde through the plate into the head (retrograde interfragmentary screw construct); and a T-plate with an interfragmentary screw from a nonarticular portion of the head antegrade into the shaft (antegrade interfragmentary screw construct). All constructs were tested for bending and torsional rigidity using an Instron mechanical testing machine (Model 306; MTS Systems, Eden Prairie, Minnesota). The highest rigidity in both bending and torsion was the antegrade interfragmentary screw construct. During bending, the antegrade interfragmentary screw construct was significantly stronger than a T-plate and nonlocked screw construct. In torsion, the retrograde interfragmentary screw construct was significantly stiffer than Kwires and approached significance over aT-plate and locked buttress pin construct. Locking bolts vs screws into the head did not significantly increase rigidity in torsion or bending. In this model, plating showed an increase in stiffness in torsional loading as compared to K-wires. The addition of a lag screw across the neck fracture consistently showed an increase in torsional and bending stiftness of the constructs. These data may assist orthopedic surgeons in determining the best fixation for radial neck fractures. [ABSTRACT FROM AUTHOR]

The aim of this study is to compare clinical and radiographic outcomes of open reduction and internal fixation versus closed reduction and percutaneous pinning of metacarpal fractures in relation to anatomic and surgical variables., Methods: Electronic medical records at two institutions were reviewed for patients who underwent surgical intervention for metacarpal fractures. Data were collected from those who underwent reduction and internal fixation with either plates or Kirschner wires (K-wires). Inclusion criteria included minimum postoperative follow-up of 60 days and age 18 years or older. Exclusion criteria included insufficient radiographic data, previously attempted closed reduction with immobilization, pathologic fracture mechanism, history of previous trauma or surgery to the affected bone, and fixation technique other than plate or K-wire., Results: We reviewed data for patients treated over a 22-year time period. Ultimately, 81 metacarpal shaft and neck fractures in 60 patients met inclusion criteria. Among all metacarpal fractures, complications were present in 39 (48.1%) cases. There were no significant associations between complication prevalence and hardware type. Revision surgery was required in 11 (13.6%) patients; there were no significant associations between revision procedures and hardware type. Postoperatively, all patients with imaging data had radiograph follow-up to assess union status. There was no significant association between time to union and hardware type., Conclusions: Outcomes showed no significant difference between plate and pin fixation for metacarpal shaft and neck fractures. These findings suggest that surgeons may have flexibility to decide on the type of operative intervention while considering patient-specific factors, such as the need for early mobilization., Competing Interests: Disclosure: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2023 The Authors.

Abstract: Application of negative-pressure wound therapy dressings to the web spaces and small, often moist, areas of the hand can be technically demanding and time consuming. The researchers present a case report and technique for managing a devastating hand infection and soft-tissue defects by creating a self-fabricated sponge glove that is easily reproducible. Vacuum-assisted therapy for combined volar dorsal soft-tissue defects of the hand, or "Hand Vac," is a novel approach for treating extensive hand wounds. This technique was used in a patient with diabetes with a deep space infection of the hand following serial debridements and antibiotic bead therapy. A single, medium-size sponge was cut using a knife and scissors to create an easily applied glove that was then sealed with adhesive dressing and a single suction port. The patient avoided complete amputation of the hand and deep infection was eradicated. The wounds had progressive granulation and healing and were eventually covered with split-thickness skin grafts. The authors conclude that severe soft-tissue defects involving both the volar and dorsal aspects of the hand can be effectively managed with a single glove-like sponge and suction port., (Copyright © 2021 Wolters Kluwer Health, Inc.

Introduction  Complex distal radius fractures often involve a fragment of the volar-ulnar articular surface and the radial styloid. The volar ulnar corner of the distal radius is an important constraint to volar translation of the carpus and thus requires stable fixation to prevent wrist displacement. The traditional volar Henry approach often requires undue tension on the median nerve while retracting for access to the ulnar aspect of the radius. To protect the median nerve from iatrogenic injury and to improve exposure of the surgical site, we propose a single incision, dual window approach to the distal radius for complex bi-columnar fractures. Methods  This technique combines the trans-Flexor Carpi Radialis (FCR) approach with a subcutaneous dissection to the ulnar aspect of the wrist. This window utilizes the interval between the ulnar neurovascular bundle and the carpal tunnel contents. Results  This technique allows the surgeon to work through either window and thus visualize and directly fixate the various fracture fragments. We have treated complex articular distal radius fractures associated with ulnar communition with this novel technique and it has provided direct reduction with improved fragment access. The surgical technique, a case presentation and results are detailed in this report. Conclusion  This case report has demonstrated that complex bi-columnar fractures of the distal radius can be effectively approached and fixated with a single incision dual window approach., Competing Interests: Conflict of Interest None declared., (Thieme.

Proximal interphalangeal joint (PIPJ) fractures and fracture-dislocations are common hand injuries and recognition of this injury pattern is essential in the management of these fractures. Although a variety of treatment options have been reported in the literature, the optimal treatment remains controversial. MEDLINE, EMBASE, and The Cochrane Library Database were screened for treatment strategies of PIPJ fracture and fracture-dislocation. Demographic data and outcome data were collected and recorded. A total of 37 studies including 471 patients and 480 fingers were reviewed. PIPJ range of motion (ROM) was greatest postoperatively in patients who underwent volar plate arthroplasty at 90.6 degrees. Dynamic external fixation resulted in the lowest PIP joint ROM with an average of 79.7 degrees. Recurrent pain and osteoarthritis were most often reported in extension block pinning at 38.5 and 46.2%, respectively. Open reduction and internal fixation had the highest rate of revision at 19.7%. Overall, the outcomes of PIP fractures and fracture-dislocations are based on the severity of injury, and the necessary treatment required. Closed reduction with percutaneous pinning and volar plate arthroplasty had good clinical and functional outcomes, with the lowest complication rates. Hemi-hamate arthroplasty and dynamic external fixation were utilized in more complex injuries and resulted in the lowest PIPJ ROM. This is a therapeutic, Level III study., Competing Interests: Conflict of Interest J.T.C. reports personal fees from Axogen and Skeletal Dynamics outside the submitted work., (© Thieme Medical Publishers.)

Background: Previous work evaluating the pronator quadratus (PQ) muscle following volar plate fixation (VPF) of distal radius fractures (DRF) suggests that PQ repair often fails in the postoperative period. The purpose of this investigation was to assess PQ repair integrity following VPF of DRF using dynamic musculoskeletal ultrasonography. Methods: Twenty adult patients who underwent VPF of DRF with repair of the PQ with a minimum follow-up of 3 months underwent bilateral dynamic wrist ultrasonography. The integrity of the PQ repair, wrist range of motion (ROM) and strength, and functional outcome scores were assessed. Results: Mean patient age at the time of surgery was 59 ± 14 years, and 50% underwent VPF of their dominant wrist. Patients were evaluated at a mean 9 ± 4 months after VPF. All patients had an intact PQ repair. The volar plate was completely covered by the PQ in 55% of patients and was associated with a larger PQ when compared to patients with an incompletely covered volar plate ( P = .026). The flexor pollicis longus tendon was in contact with the volar plate in 20% of patients, with those patients demonstrating a trend toward significantly increased wrist flexion ( P = .053). No difference in ROM, strength, or outcome scores was noted among wrists with completely or incompletely covered volar plates. Conclusions: The PQ demonstrates substantial durability after repair following VPF. Wrist ROM, strength, and functional outcomes are similar in wrists in which the volar plate is completely or incompletely covered by the repaired PQ.

Background: Over 500 000 carpal tunnel releases costing over $2 billion are performed each year in the United States. The study's purpose is to perform a cost-minimizing analysis to identify the least costly strategy for carpal tunnel syndrome treatment utilizing existing success rates based on previously reported literature., Methods: We evaluate the expected cost of various treatment strategies based on the likelihood of further treatments: (1) a single steroid injection followed by surgical release; (2) up to 2 steroid injections before surgical release; (3) 3 steroid injections before surgery, and (4) immediate surgical release. To reflect costs, we use our institution's billing charges to private payers and reimbursements from Medicare. A range of expected steroid injection success rates are employed based on previously published literature., Results: Immediate surgical release is the costliest treatment with an expected cost of $2149 to $9927 per patient. For immediate surgical release to cost less than a single injection attempt, the probability of surgery after injection would need to exceed 80% in the Medicare reimbursement model and 87% in the institutional billing model. A single steroid injection with subsequent surgery, if needed, amounts to a direct cost savings of $359 million annually compared with immediate surgical release. Three injections before surgery, with "high" expected success rates, represent the cost-minimizing scenario., Conclusions: Although many factors must be considered when deciding upon treatment for carpal tunnel syndrome, direct payer cost is an important component, and the initial management with steroid injections minimizes these direct payer costs.

Background  Open carpal tunnel release (CTR) is one of the most commonly performed operative procedures with operative duration being a primary metric of operating room efficiency. The purpose of this study was to identify factors associated with prolonged operative duration, in performing CTR. Materials and Methods  CTR cases performed by a single surgeon from September 2013 to October 2015 were reviewed. Patient age at the time of surgery, sex, location of surgery (specialty orthopaedic hospital versus ambulatory surgery center), body mass index (BMI), American Society of Anesthesiologists classification, total operative duration (TOD), and procedure time (PT) were recorded. Obesity was defined as BMI > 30 and morbid obesity was defined as BMI > 35. Data were analyzed to identify factors associated with prolonged TOD or PT. Results  One hundred and nine consecutive patients underwent isolated CTR. Mean age at time of surgery was 62 years (range: 24-92 years). Nonobese patients were found to have significantly shorter TOD than obese patients (22.3 vs. 24.4 minutes). Similarly, patients who were not morbidly obese had significantly shorter TOD than morbidly obese patients (22.6 vs. 26 minutes). No other factors were associated with prolonged TOD. No difference in PT was found between normal weight, obese, and morbidly obese groups. Conclusions  TOD, but not procedure time, is significantly affected by obesity. Our findings are relevant when scheduling and preparing obese patients for surgery, which may have a significant impact on health resource utilization. Level of Evidence  This is a Level III, economic/decision analysis study.

Background: Health disparities exist among many patient populations, with race, payer status, hospital size and access to teaching versus non-teaching hospitals potentially affecting whether certain patients have access to the benefits of total wrist arthroplasty (TWA)., Methods: The National Inpatient Sample Database (NIS) was queried from 2001 to 2013 for TWA using the ICD-9 code 81.73. Patient-level data included age, sex, race, payer status, and year of discharge. Hospital-level data included hospital bed size, location, teaching status, and region., Results: There were 1,213 patients identified who underwent TWA between 2001 and 2013. Total number of procedures decreased from 88 TWAs in 2001 to 65 in 2013. The yearly volume ranged from 33 in 2005 to 128 in 2007. The male-female ratio was 2.5 to 1. The majority of TWA procedures were performed at urban teaching hospitals (60.8%)., Conclusions: The NIS database shows a downward trend of total wrist arthroplasty utilization. The majority of total wrist arthroplasties were performed at urban teaching hospitals indicating treatment occurs most often at academic centers of excellence.

Context: Major League Baseball (MLB) players are at risk of hook of hamate fractures. There is a paucity of data assessing the effect of a hook of hamate fracture on MLB players' future athletic performance., Objective: To determine if MLB players who sustain hook of hamate fractures demonstrate decreased performance upon return to competition when compared with their performance before injury and that of their control-matched peers., Design: Retrospective case-control design., Setting: Retrospective database study., Participants: 18 MLB players who sustained hook of hamate fractures., Methods: Data for 18 MLB players with hook of hamate fractures incurred over 26 seasons (1989-2014) were obtained from injury reports, press releases, and player profiles ( www.mlb.com and www.baseballreference.com ). Player age, position, number of years in the league, mechanism of injury, and treatment were recorded. Individual season statistics for the 2 seasons immediately prior to injury and the 2 seasons after injury for the main performance variable-Wins Above Replacement-were obtained. Eighteen controls matched by player position, age, and performance statistics were identified. A performance comparison of the cohorts was performed., Main Outcome Measures: Postinjury performance compared with preinjury performance and matched-controls., Results: Mean age at the time of injury was 25.1 years with a mean of 4.4 seasons of MLB experience prior to injury. All injuries were sustained to their nondominant batting hand. All players underwent operative intervention. There was no significant change in Wins Above Replacement or isolated power when preinjury and postinjury performance were compared. When compared with matched-controls, no significant decline in performance in Wins Above Replacement the first season and second season after injury was found., Conclusion: MLB players sustaining hook of hamate fractures can reasonably expect to return to their preinjury performance levels following operative treatment.

The aim of this investigation was to examine graduating orthopedic resident case logs to evaluate trends in performing pediatric orthopedic procedures and compare pediatric orthopedic case volume among residents in the 90th, 50th, and 10th percentiles (by case volume) to identify caseload variation. Accreditation Council for Graduate Medical Education orthopedic resident case logs were examined for graduating years 2007-2013. Linear regression analyses were carried out to assess temporal trends in pediatric orthopedic case volume. Subgroup analyses were carried out to assess trends in cases by anatomic location. Comparisons of the number of pediatric cases performed by the 90th, 50th, and 10th percentiles of graduating residents were also performed. Pediatric orthopedic case volume increased significantly per graduating resident (295.9-373.2; P<0.001) from 2007 to 2013. Graduating residents in the 90th (494-573; P=0.001), 50th (264-334; P<0.001), and 10th (144-216; P=0.003) percentiles of case volume all sustained significant increases in the number of pediatric orthopedic cases performed. Subgroup analyses showed significant increases in pediatric orthopedic shoulder (4.8-7.3; P<0.001), humerus/elbow (25.9-32.7; P<0.001), forearm/wrist (28.6-40.4; P<0.001), hand/finger (15-16.9; P=0.005), femur/knee (44.5-51.9; P=0.002), leg/ankle (39.4-41.1; P=0.004), and spine case volume (24.9-33.6; P<0.001). On average, graduating residents in the 90th, 50th, and 10th percentiles performed 524, 302, and 169 cases, respectively. The current investigation shows significant growth in the number of pediatric orthopedic cases performed by graduating residents, particularly among upper extremity procedures. However, considerable variation in pediatric orthopedic case volume exists among residents. Although the educational effects of this case volume variation are incompletely understood, the current investigation may be beneficial in efforts to improve pediatric orthopedic educational quality.

Despite educational focus regarding orthopedic oncology during residency, assessment of resident orthopedic oncology caseload has not been performed. The purpose of this study was to evaluate orthopedic oncology caseload trends and variation among residents. The Accreditation Council for Graduate Medical Education case log reports for orthopedic surgery residents were reviewed for graduating years 2007 to 2013. Trends in orthopedic oncology cases and variation in the median number of cases performed by residents in the 90th, 50th, and 10th percentiles of caseload were evaluated. The proportion of orthopedic oncology caseload among all cases performed by residents increased significantly (P = 0.005) from 2007 to 2013. Likewise, the mean number of adult (P = 0.002), pediatric (P = 0.003), and total orthopedic oncology cases increased significantly (P = 0.002). On average, residents in the 90th, 50th, and 10th percentiles performed 83, 28, and 3 cases, respectively. The current study demonstrates a significant increase in adult, pediatric, and total orthopedic oncology caseload. There is also evidence of substantial caseload variation among residents. Caseload variation may influence the education and technical proficiency of orthopedic residents.

Background: Forearm immobilization techniques are commonly used to manage distal radius, scaphoid, and metacarpal fractures. The purpose of our study was to compare the degree of rotational immobilization provided by a sugar-tong splint (STS), short arm cast (SAC), Munster cast (MC), and long arm cast (LAC) at the level of the distal radioulnar joint (DRUJ), carpus, and metacarpals., Methods: Seven cadaveric upper extremity specimens were mounted to a custom jig with the ulnohumeral joint fixated in 90° of flexion. Supination and pronation were unrestricted. K-wires were placed in the distal radius, scaphoid, and metacarpals using fluoroscopic guidance to measure the total arc of rotation referenced to the ulnar ex-fix pin. Baseline measurements followed by sequential immobilization with well-molded STS, SAC, MC, and LAC were obtained with 1.25, 2.5, and 3.75 ft-lb of supination and pronation force directed through the metacarpal K-wire. Each condition was tested 3 times. Digital photographs were taken perpendicular to the ulnar axis to analyze the total arc of motion., Results: The most effective constructs from least to greatest allowed rotational arcs were LAC, MC, SAC, and STS. Above-elbow constructs (MC, LAC) demonstrated superior immobilization compared with below-elbow constructs (SAC) ( P < .001). Circumferential constructs (SAC, MC, LAC) were superior to the noncircumferential construct (STS) ( P < .001). There were no significant differences between the MC and LAC in all conditions tested., Conclusions: Both circumferential and proximally extended immobilization independently improved rotational control of the wrist. However, extending immobilization proximal to the epicondyles did not confer additional stability.

Radial shaft convergence in distal radius fractures is often misdiagnosed. This common deformation is often associated with a radial translation of the distal fragment. This parameter has to be corrected because of the increased risk of distal radioulnar joint instability due to detensioning of the distal interosseous membrane if there is an associated triangular fibrocartilage complex lesion. A new radiologic sign for diagnosis of proximal radius convergence during distal radius fracture is presented as well as technical tips for correction of this deformity.

Flexor tendon injuries of the hand are uncommon, and they are among the most challenging orthopaedic injuries to manage. Proper management is essential to ensure optimal outcomes. Consistent, successful management of flexor tendon injuries relies on understanding the anatomy, characteristics and repair of tendons in the different zones, potential complications, rehabilitation protocols, recent advances in treatment, and future directions, including tissue engineering and biologic modification of the repair site.

Background: Intramedullary headless screw (IMHS) has shown promise as an alternative to other fixation devices for metacarpal neck fractures. The purpose of this study was to assess the biomechanical performance of IMHS versus the commonly-used crossed K-wire technique. We hypothesized that IMHS fixation provides superior stability to K-wires., Methods: A metacarpal neck fracture model in 23 human cadaveric metacarpals was created. The specimens were divided into two groups based upon fixation method: Group 1, 3 mm intramedullary headless screw; and Group 2, 0.045 inch crossed K-wires. A cantilever bending model was used to assess load-to-failure (LTF), maximum displacement, energy absorption, and stiffness., Results: The mean LTF was 70.6 ± 30.1 N for IMHS and 97.5 ± 34.7 N for crossed K-wires. Mean stiffness was 11.3 ± 3.4 N/mm and 17.7 ± 7.8 N/mm for IMHS and crossed K-wires, respectively. The mean maximum displacement was 20.2 ± 4.6 mm for IMHS and 24.1 ± 3.7 mm for crossed K-wires. Moreover, mean energy absorption was 778.3 ± 528.9 Nmm and 1095.9 ± 454.4 Nmm, respectively, for IMHS and crossed K-wires. Crossed K-wires demonstrated significantly higher stiffness and maximum displacement than IMHS (p < 0.05)., Conclusions: IMHS fixation of unstable metacarpal neck fractures offers less stability compared to crossed K-wires when loaded in bending., Clinical Relevance: Crossed K-wires offer superior stability for the treatment of metacarpal neck fractures. These results reveal that IMHS fixation is less favorable biomechanically and should be cautiously selected with regards to fracture stability., Competing Interests: The authors did not receive any funding for this study/ manuscript.

Background: Microsurgery is a specialized surgical technique with wide clinical application. The purpose of this study was to analyze case logs of graduating orthopedic surgery residents to assess trends in case volume for microsurgery procedures., Methods: Accreditation Council for Graduate Medical Education case log reports were analyzed for microsurgery experience from 2007 to 2013. The mean number of adult, pediatric, and total microsurgery cases was noted. In addition, the median number of microsurgery procedures performed by the 90th, 50th, and 10th percentiles of residents (by case volume) was recorded. Temporal changes in case volume were calculated utilizing linear regression analyses., Results: The proportion of microsurgery procedures increased significantly (1.3% to 2%; P = .024). The mean number of adult (24.5 to 41.9; P = .01), pediatric (1.9 to 3.4; P = .011), and total (26.3 to 45.3; P = .01) microsurgery procedures also increased significantly. Similarly, residents in both the 90th (63 to 109; P = .01) and 50th (10 to 21; P = .036) percentiles sustained significant increases in the median number of microsurgery procedures. No change was noted for residents in 10th percentile (0 to 0; P > .999). Graduating residents in the 90th percentile performed over 6 times more microsurgery procedures than residents in the 50th percentile., Conclusions: Microsurgical caseload is increasing among graduating orthopedic residents. However, there is substantial variability in resident microsurgery case volume. Future investigations are needed to explore the educational implications of these findings and should seek to correlate microsurgical caseload with competency.

Background: We compared 3 surgical approaches to the MP joint: a dorsal extensor tendon-splitting approach, a dorsal extensor tendon-reflecting parasagittal approach, and the volar A1 pulley approach. We quantitatively compared each of these approaches by measuring the amount of articular cartilage exposed on the base of the proximal phalanx. We hypothesize that visualization of the articular cartilage of the proximal phalangeal base is enhanced with the volar approach., Methods: The MP joints of the 32 available digits were randomly assigned to 1 of 3 surgical approaches: extensor tendon splitting (A), extensor tendon reflecting (B), or volar approach (C). After each approach, the visible articular surface of the base of the proximal phalanx was stained with methylene blue. The MP joints were then disarticulated, and the proximal phalanges were digitally mapped using a 3-dimensional digitizer. Three-dimensional computer software was used to analyze and calculate the dyed exposed surface area and total surface area of each specimen., Results: The mean % exposed joint surface area for the dorsal extensor splitting, dorsal extensor reflecting and volar approaches were 62%, 67% (over the dorsal side of the proximal phalanx) and 54% (over the volar side of the proximal phalanx), respectively. Multiple linear regression showed statistical significance for a smaller percentage of articular surface area exposed with the volar approach. However, this was not clinically significant. A significant association was found between location in the small finger and greater % exposed joint surface, compared to approaches in the index finger. In all volar approach specimens, the collateral insertion site was visible, but not in the dorsal approach specimens., Conclusions: Knowledge of the limits of each exposure is essential for planning the most appropriate surgical approach. The A1 pulley approach provided greater access to the volar 50% of the joint and collateral ligament insertion without violating the extensor mechanism. The amount of joint surface visualized through all 3 approaches was not significantly different. However, based on the accessibility to the collateral ligament insertion site among three different approaches, we recommend the volar A1 pulley approach for treatment of avulsion fractures of the base of the proximal phalanx. For other injuries of the MP joint, including the intra-articular proximal phalanx base fractures, and metacarpal head fractures, the dorsal approaches are still indicated.

Distal radius fracture (DRF) is a common injury. Treatment options have evolved and now several can be used to address even the most complex fracture patterns. Complex fractures of the distal radius and ulna can be challenging, and specific goals must be kept in mind to achieve definitive anatomical and functional restoration. This article summarizes the concepts, principles, and surgical options regarding complex DRF reconstruction., Competing Interests: Authors’ Disclosure Statement: The authors report no actual or potential conflict of interest in relation to this article.

The internet is a popular resource for orthopedic fellowship applicants. We conducted a study to assess the accessibility of orthopedic trauma fellowship (OTF) program websites and to evaluate the content on the sites. We queried the online database of the Orthopaedic Trauma Association (OTA) and the online Fellowship and Residency Electronic Interactive Database (FREIDA) to assess available OTF program links. We used Google to assess how accessible the sites are from outside the databases. We then analyzed accessible sites for content pertinent to OTF applicants. Of the 49 OTF programs identified, 42 (86%) had their websites accessible from Google and FREIDA links. The OTA database had no OTF website links. Analysis of the 42 accessible OTF sites revealed they had an average of 40% (range, 0%-75%) of assessed content, with operative experience on 88% of sites and a program description on 93% of sites. OTF programs with >1 fellow had significantly more education content (48% vs 33%; P = .043) and total content (46% vs 37%; P = .01) on their sites than OTF programs with 1 fellow. Accessibility and content of OTF websites are highly variable and largely deficient. OTF programs should focus on improving their website accessibility and content., Competing Interests: Authors’ Disclosure Statement: The authors report no actual or potential conflict of interest in relation to this article.

Purpose: Surgical costs are under scrutiny and surgeons are being held increasingly responsible for cost containment. In some instances, implants are the largest component of total procedure cost, yet previous studies reveal that surgeons' knowledge of implant prices is poor. Our study aims to (1) understand drivers behind implant selection and (2) assess whether educating surgeons about implant costs affects implant selection., Methods: We surveyed 226 orthopedic surgeons across 6 continents. The survey presented 8 clinical cases of upper extremity fractures with history, radiographs, and implant options. Surgeons were randomized to receive either a version with each implant's average selling price ("price-aware" group), or a version without prices ("price-naïve" group). Surgeons selected a surgical implant and ranked factors affecting implant choice. Descriptive statistics and univariate, multivariable, and subgroup analyses were performed., Results: For cases offering implants within the same class (eg, volar locking plates), price-awareness reduced implant cost by 9% to 11%. When offered different models of distal radius volar locking plates, 25% of price-naïve surgeons selected the most expensive plate compared with only 7% of price-aware surgeons. For cases offering different classes of implants (eg, plate vs external fixator), there was no difference in implant choice between price-aware and price-naïve surgeons. Familiarity with the implant was the most common reason for choosing an implant in both groups (35% vs 46%). Price-aware surgeons were more likely to rank cost as a factor (29% vs 21%)., Conclusions: Price awareness significantly influences surgeons' choice of a specific model within the same implant class. Merely including prices with a list of implants leads surgeons to select less expensive implants. This implies that an untapped opportunity exists to reduce surgical expenditures simply by enhancing surgeons' cost awareness., Type of Study/level of Evidence: Economic/Decision Analyses I., (Copyright © 2017 American Society for Surgery of the Hand.

Background: The Internet has been reported to be the first informational resource for many fellowship applicants. The objective of this study was to assess the accessibility of orthopaedic foot and ankle fellowship websites and to evaluate the quality of information provided via program websites., Methods: The American Orthopaedic Foot and Ankle Society (AOFAS) and the Fellowship and Residency Electronic Interactive Database (FREIDA) fellowship databases were accessed to generate a comprehensive list of orthopaedic foot and ankle fellowship programs. The databases were reviewed for links to fellowship program websites and compared with program websites accessed from a Google search. Accessible fellowship websites were then analyzed for the quality of recruitment and educational content pertinent to fellowship applicants., Results: Forty-seven orthopaedic foot and ankle fellowship programs were identified. The AOFAS database featured direct links to 7 (15%) fellowship websites with the independent Google search yielding direct links to 29 (62%) websites. No direct website links were provided in the FREIDA database. Thirty-six accessible websites were analyzed for content. Program websites featured a mean 44% (range = 5% to 75%) of the total assessed content. The most commonly presented recruitment and educational content was a program description (94%) and description of fellow operative experience (83%), respectively., Conclusions: There is substantial variability in the accessibility and quality of orthopaedic foot and ankle fellowship websites., Clinical Relevance: Recognition of deficits in accessibility and content quality may assist foot and ankle fellowships in improving program information online., Levels of Evidence: Level IV.

Background: The aim of this study was to assess national trends in the utilization and complication rates of total wrist arthroplasty (TWA) and total wrist fusion (WF) as identified via review of the American Board of Orthopedic Surgery (ABOS) Part II candidate database., Methods: The ABOS Part II candidate database is a collection of cases reported by candidates of the ABOS Part II board certification oral exam. The ABOS database was queried for all TWA and WF cases performed from 2005 to 2014. Linear regression analyses were used to assess trends in procedure utilization. Treatment diagnoses, patient characteristics, and reported complications were also compared between the 2 treatment cohorts., Results: No significant increases in the proportion of candidates performing TWA or WF, number of TWA or WF cases, nor the number of TWA or WF cases performed per candidate performing those procedures were noted during the study period. Significantly less TWA cases were performed when compared with WF cases (68 vs 327; P = .006). Patients undergoing TWA were significantly older ( P = .005), more likely female ( P < .001), and more likely to have a diagnosis of osteoarthritis ( P = .003) than patients undergoing WF. There were no significant differences in complication rates, including postoperative infection, nerve palsy, or rate of secondary surgery, between the TWA and WF cohorts., Conclusions: Utilization of both TWA and WF has remained unchanged among emerging career orthopedic surgeons. Although WF is performed nearly 5 times more frequently than TWA, our short-term findings suggest that TWA compares favorably with WF.

Background: Trochanteric osteotomy still has an important role in hip arthroplasty in cases of (1) preexisting developmental hip dysplasia with superior subluxation, (2) revision arthroplasty, specifically with acetabular component revision in the face of well-fixed femoral component, and (3) recurrent dislocation without component loosening or malalignment, in treatment of complicated trochanteric fixation in osteoporotic bone and nonunions may be difficult. This study reports the clinical outcomes of trochanteric fixation following total hip arthroplasty (THA) utilizing a hook plate construct in a cohort of ten patients., Materials and Methods: The Arbeitsgemeinschaft für Osteosynthesefragen (AO) articulated hook plate was used in nine cases of established approach related nonunion following THA and in one case of osteopenic bone during primary THA. All ten patients returned for interviews and clinical examination. The average time for clinical followup was 35 months (range 5-48 months). The mean age of the study cohort was 65 years (range 56-74 years). Time to union and incidence of postoperative complications were assessed., Results: Union occurred in all ten cases at an average of 3.3 months postoperatively. One patient developed symptomatic trochanteric bursitis and required plate removal. Another patient developed a superficial infection which was successfully treated with local wound debridement and antibiotics. A third patient developed a symptomatic neuroma at the site of the iliac crest bone harvest and was successfully treated with excision of the neuroma. No catastrophic implant failures occurred., Conclusions: The articulated design of the plate allows for ease in application and functional construct stability. The articulated hook plate is an option for fixation of osteopenic bone fragments and established nonunions of the greater trochanter., Competing Interests: There are no conflicts of interest.

Background: Whether percutaneous pinning or plate fixation is more appropriate for metacarpal fractures is still open to debate. Our study purpose was to review the current literature in an attempt to determine the optimal treatment modality for metacarpal fractures on the basis of functional outcomes, radiographic outcome and rates of complications., Methods: We selected Pubmed, Cochrane library, EMBASE and the relevant English orthopedic journals and pooled data from eligible trials including four comparative studies and one retrospective review. Overall, the studies contained 222 patients with 231 fractures, 143 treated with pinning and 88 treated with plates and screws. Mean follow up was 7.5 months (4-12 months). Data were analyzed and the fixed effects are assumed for meta-analysis., Results: Patients undergoing pinning for metacarpal fractures have higher motion scores when compared to open reduction and internal fixation with plate and screws. Functional scores, grip strength, radiographic parameters, time to union and complications were found not to be significantly different between the two groups., Conclusions: There is evidence to support the use of pins over ORIF with plates and screws in the treatment of metacarpal fractures. This may have practical advantages, including minimal dissection, easier insertion and availability of the pins. The limitations of this study include the small number of eligible studies, lack of reporting of standard deviation value, and the lack of DASH score assessments at follow up. Further randomized controlled trials that include a larger patient numbers with longer follow up are needed to substantiate the superiority of one fixation method over another.

Background: Distal radius fractures (DRFs) are common geriatric fractures with the overall incidence expected to increase as the population continues to age. The purpose of this investigation was to compare the short-term complication rates in geriatric versus nongeriatric cohorts following osteosynthesis of DRFs., Methods: The American Board of Orthopaedic Surgery (ABOS) part II database was queried for adult DRF cases performed from 2007 to 2013. Current Procedural Terminology codes were used to identify cases treated via osteosynthesis. Patient demographic information and reported complication data were analyzed. Comparisons between geriatric (age ≥65 years) and nongeriatric (age <65 years) patients were performed., Results: From 2007 to 2013, a total of 9867 adult DRFs were treated via osteosynthesis by ABOS part II candidates. Geriatric patients comprised 28% of the study cohort. Mean age of the geriatric and nongeriatric cohorts was 74 ± 7 and 46 ± 13 years, respectively. There was a greater proportion of female patients ( P < .001) in the geriatric cohort as compared with the nongeriatric cohort. The geriatric cohort demonstrated higher rates of anesthetic complications ( P = .021), iatrogenic bone fracture ( P = .021), implant failure ( P = .031), loss of reduction ( P = .001), unspecified medical complications ( P = .007), and death ( P = .017) than the nongeriatric cohort. The geriatric cohort also showed lower rates of nerve palsy ( P = .028) when compared with the nongeriatric cohort, though no differences in rates of secondary surgery were noted between the two cohorts., Conclusion: Increased rates of complications related to poor bone quality and poor health status may be expected among geriatric patients following osteosynthesis of DRFs. However, geriatric and nongeriatric patients have similarly low rates of secondary surgery. Future studies are needed to delineate the economic, functional, and societal impact of geriatric DRFs treated via osteosynthesis., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: The purpose of this study was to determine the factors that affect hand surgeon operating room (OR) turnover time. We hypothesized that surgeon presence in the OR, decreased American Society of Anesthesiologists (ASA) class, smaller case type, and earlier case time, as well as other factors, decreased OR turnover time. Methods: A total of 685 hand surgery cases performed by 5 attending hand surgeons between September 2013 and December 2014 were identified. Turnover time, patient comorbidities (ASA class), surgeon, prior OR surgical procedure, current OR surgical procedure, location of the surgery (ambulatory surgical center [ASC] vs orthopedic specialty hospital [OSH]), time of surgery, and order of OR cases were recorded. The effect of surgeon routine variables, OR case factors, and patient health status on OR turnover was analyzed. Results: Turnover time was significantly shorter in cases where the surgeon remained in the OR during turnover (27.5 minutes vs 30.4 minutes) and when the surgeon incentivized OR staff (24 minutes vs 29 minutes). The ASC was found to have shorter turnover times than the OSH (27.9 minutes vs 36.4 minutes). In addition, ASA class, type of prior OR procedure, type of current OR procedure, and case order all significantly affected turnover time. Comparison of OR turnover time among the 5 surgeons revealed a statistically significant difference at the OSH but not at the ASC. Conclusion: OR turnover time is significantly affected by surgeon routine, location of surgery, patient ASA class, procedure type, and case order. Interestingly, the effect of hand surgeon routine on OR turnover time may be amplified at an academic OSH versus an ASC., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Recently, intramedullary headless screw (IMHS) has shown promise as an alternative to dorsal plate fixation of metacarpal fractures. The purpose of this study was to assess the biomechanical performance of IMHS versus plating. We hypothesized that IMHS fixation provides inferior stability to plating. Methods: Metacarpal fracture model with 3-mm of volar gapping in forty-four human cadaveric metacarpals was created. The specimens were divided into 5 groups: Group 1, 1.5-mm non-locking plate; Group 2, 1.5-mm locking plate; Group 3, 2.0-mm non-locking plate; Group 4, 2.0-mm locking plate; and Group 5, 2.4-mm short cannulated IMHS. A 4-point bending model was used to assess load-to failure (LTF) and stiffness. Results: Mean LTF was 364 ± 130 N for 1.5-mm non-locking plates, 218 ± 94 N for 1.5-mm locking plates, 421 ± 86 N for 2.0-mm non-locking plates, 351 ± 71 N for 2.0-mm locking plates, and 75 ± 20 N for IMHS. Mean stiffness was 91 ± 12 N/mm for 1.5-mm non-locking plates, 110 ± 77 N/mm for 1.5-mm locking plates, 94 ± 20 N/mm for 2.0-mm non-locking plates, 135 ± 16 N/mm for 2.0-mm locking plates, and 55 ± 15 N/mm for IMHS. IMHS demonstrated significantly lower LTF and stiffness than plates. Conclusions: IMHS fixation of unstable metacarpal shaft fractures offers less stability compared to plating when loaded in bending. The LTF and stiffness of IMHS versus plating of metacarpal shaft fractures has not been previously quantified. Our results reveal that IMHS fixation is less favorable biomechanically and should be carefully chosen in regards to fracture stability., Competing Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: J.T.C. is on the Speakers Bureau for Integra Life Sciences and is a consultant for Wright Medical Technology.

Background: The aim was to determine whether players in the National Basketball Association (NBA) who sustain metacarpal fractures demonstrate decreased performance upon return to competition when compared with their performance before injury and that of their control-matched peers. Methods: Data for 32 NBA players with metacarpal fractures incurred over 11 seasons (2002-2003 to 2012-2013) were obtained from injury reports, press releases, and player profiles (www.nba.com and www.basketballreference.com). Player age, body mass index (BMI), position, shooting hand, number of years in the league, and treatment (surgical vs nonsurgical) were recorded. Individual season statistics for the 2 seasons immediately prior to injury and the 2 seasons after injury, including player efficiency rating (PER), were obtained. Thirty-two controls matched by player position, age, and performance statistics were identified. A performance comparison of the cohorts was performed. Results: Mean age at the time of injury was 27 years with an average player BMI of 24. Players had a mean 5.6 seasons of NBA experience prior to injury. There was no significant change in PER when preinjury and postinjury performances were compared. Neither injury to their shooting hand nor operative management of the fracture led to a decrease in performance during the 2 seasons after injury. When compared with matched controls, no significant decline in performance in PER the first season and second season after injury was found. Conclusion: NBA players sustaining metacarpal fractures can reasonably expect to return to their preinjury performance levels following appropriate treatment., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: There is poor consensus in the literature regarding associated functional limitation and the preferred wrist position for total wrist arthrodesis. The purpose of the current investigation was twofold: (1) to assess the functional limitations of wrist arthrodesis and (2) to determine the optimal position for wrist arthrodesis using a simulated wrist fusion model. Methods: Twenty healthy volunteers underwent simulated wrist arthrodesis in 6 different positions using custom-molded wrist splints: 15° extension with 0° radio-ulnar deviation, 15° extension with 10° ulnar deviation, 15° extension with 10° radial deviation, 0° extension with 0° radio-ulnar deviation, 0° extension with 10° ulnar deviation, and 0° extension with 10° radial deviation. Each volunteer was independently assessed for wrist function using the Jebsen-Taylor hand function test, grip strength, and satisfaction in the simulated wrist fusion positions. Comparisons between all simulated fusion wrists and the baseline unsplinted wrist as well as among the 6 simulated fusion positions were performed. Results: Turning over a card (5.1 vs 4.3 seconds), picking up small objects (7.1 vs 5.8 seconds), and simulated feeding (8.3 vs 7.1 seconds) as well as total Jebsen-Taylor test duration (41.8 vs 37.9 seconds) was significantly longer in simulated fusion wrists. Both grip strength (55.9 vs 80.7 kg) and satisfaction scores (6.4 vs 9.6) were lower in simulated fusion wrists. Wrists in 0° extension also demonstrated significantly shorter durations in stacking checkers than wrists in 15° extension. Conclusion: Our findings suggest that wrist arthrodesis may only compromise select wrist functions. Among the tested wrist fusion positions, wrists fused in neutral may demonstrate better function than wrist fused in slight extension. However, grip strength and satisfaction seem to be unaffected by wrist fusion position., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

The volar Henry approach is most commonly used for surgical fixation of distal radius fractures. However, this approach is limited in achieving adequate exposure for the fixation of the volar-ulnar portion of the distal radius, rendering it difficult for the ideal placement of the fixation construct. We propose the use of the extensile volar-ulnar approach for fixation of distal radius fracture involving a small volar-ulnar fragment. This approach allows optimal reduction of the sigmoid notch and the volar lunate facet, which anatomically reduces both the radiocarpal joint and the sigmoid notch. In addition, extension of this approach may safely be performed if concomitant carpal tunnel release is necessary., (Copyright © 2016 American Society for Surgery of the Hand.

Background  An accessory slip arising from the extensor carpi ulnaris (ECU) tendon that inserts on the fifth metacarpal bone has been identified. We describe the frequency of this accessory slip arising from the ECU tendon and provide both qualitative and quantitative description of the slip via cadaveric examination. Methods  Fifty (28 males and 22 females) cadaveric upper extremity specimens were examined after loupe-aided dissection of the dorsoulnar wrist and hand with identification of the ECU tendon. The presence of an accessory slip arising from the ECU tendon was noted. The insertion and morphology of the accessory slip was also described. Results  An accessory slip arising from the ECU tendon at the level of the radiocarpal joint was found to insert on the fifth metacarpal bone in 11 (22%) specimens. Nine accessory slips inserted at the base of the fifth metacarpal (Nakashima Type A) and two inserted at the fifth metacarpal head (Nakashima Type C). Mean width of the accessory slip was 1.2 ± 0.4 mm. No evidence of sexual dimorphism was found regarding the morphology of the accessory slip. Conclusion  The current study demonstrates the relative frequency and morphology of the accessory slip arising from the ECU tendon. This variant should be of diagnostic consideration in ailments of the dorsoulnar wrist and hand. Hand surgeons should be aware of this anatomic variant and its potential for clinical manifestation.

Background: The objectives of this investigation were to report temporal trends in resident performed upper extremity fracture procedures and analyze case volume variability., Methods: Orthopaedic resident case logs from the Accreditation Council for Graduate Medical Education were reviewed for graduating years 2007 to 2014. The mean number of wrist, forearm, elbow, humerus, and shoulder fracture-dislocation procedures performed by residents was analyzed. The median number of procedures reported by the top 30% and bottom 30% of residents (by case volume) was also recorded. Linear regression modeling was used to assess temporal trends., Results: The mean number of wrist and forearm fracture cases performed per resident fell from 55.3 in 2007 to 46.7 in 2014 (p = 0.325) while the number of elbow and humerus fracture procedures remained relatively constant (45.6 to 45.4; p = 0.224). The mean number of shoulder fracture cases increased significantly (14.7 to 22.5; p < 0.001). Over the 8-year period, residents in the 70th percentile of caseload performed significantly more wrist and forearm (62.6 versus 39.5; p < 0.001), elbow and humerus (55 versus 34.9; p < 0.001), and shoulder (23 versus 12.9; p < 0.001) fracture procedures than residents in the 30th percentile., Conclusion: Resident case volume for wrist, forearm, elbow, and humerus fractures is constant or falling. However, shoulder fracture caseloads are increasing. Regardless, there is substantial disparity in upper extremity fracture case volume among residents. Further investigation is needed to assess possible educational effects of resident caseload disparity.

The Internet is a common resource for applicants of hand surgery fellowships, however, the quality and accessibility of fellowship online information is unknown. The objectives of this study were to evaluate the accessibility of hand surgery fellowship Web sites and to assess the quality of information provided via program Web sites. Hand fellowship Web site accessibility was evaluated by reviewing the American Society for Surgery of the Hand (ASSH) on November 16, 2014 and the National Resident Matching Program (NRMP) fellowship directories on February 12, 2015, and performing an independent Google search on November 25, 2014. Accessible Web sites were then assessed for quality of the presented information. A total of 81 programs were identified with the ASSH directory featuring direct links to 32% of program Web sites and the NRMP directory directly linking to 0%. A Google search yielded direct links to 86% of program Web sites. The quality of presented information varied greatly among the 72 accessible Web sites. Program description (100%), fellowship application requirements (97%), program contact email address (85%), and research requirements (75%) were the most commonly presented components of fellowship information. Hand fellowship program Web sites can be accessed from the ASSH directory and, to a lesser extent, the NRMP directory. However, a Google search is the most reliable method to access online fellowship information. Of assessable programs, all featured a program description though the quality of the remaining information was variable. Hand surgery fellowship applicants may face some difficulties when attempting to gather program information online. Future efforts should focus on improving the accessibility and content quality on hand surgery fellowship program Web sites.

Background: Total wrist arthroplasty (TWA) provides the requisite range of motion to accomplish activities of daily living, especially for low-demand patients with bilateral wrist arthritis. However, there are no large epidemiologic studies to evaluate nationwide trends of TWA and wrist fusion (WF)., Questions/purposes: To analyze data collected from the National Inpatient Sample (NIS) to compare utilization, demographic, and outcome data among patients undergoing TWA versus total WF. We hypothesized that utilization rates of TWA have significantly increased over the prior decade in the United States., Methods: NIS data from 2001 to 2010 were reviewed. Procedures were identified by ICD-9-CM codes 81.73 (TWA) and 81.25 (WF). Utilization rates, primary treatment diagnoses, patient demographic and medical comorbidity data, and procedure costs were compared between TWA and WF., Results: There was a decrease in the number of procedures per year for TWA, while the number of WF remained relatively unchanged. There was, however, a transient increase in the frequency of TWA procedures performed from 2005 to 2008, following a decline in 2005. Patients with traumatic arthritis were more likely to receive WF. Rheumatoid patients were more likely to receive TWA. Patients receiving TWA tended to be older, female, be insured by Medicare, have a greater comorbidity burden, and have rheumatologic disease., Conclusion: WF was performed nearly four times more frequently than TWA. A trend was demonstrated toward a decreasing number of TWA being implanted, and in patients with more underlying comorbidities. TWA was associated with a higher hospitalization charge, which may be expected given the higher implant costs associated with arthroplasty., Level of Evidence: Level II, prognostic study.

Purpose: To assess the risk of injury to the dorsal sensory branch of the ulnar nerve (DSBUN) with percutaneous pinning of commonly stabilized ulnar-sided structures., Methods: Eleven fresh-frozen cadaveric upper extremities were assessed. Percutaneous pinning of the fifth metacarpal base and neck, lunotriquetral joint, ulnar styloid, and distal radioulnar joint (DRUJ) with 1.4-mm Kirschner wires was performed under fluoroscopic guidance. Each specimen was then carefully dissected and the distance from each pin to the DSBUN was measured using a digital caliper. Direct injury to the DSBUN and pins found immediately adjacent to the nerve were recorded., Results: Mean distance from the pin to the DSBUN at the fifth metacarpal neck was 5.0 ± 1.5 mm; fifth metacarpal base, 2.3 ± 2.2 mm; lunotriquetral joint, 1.8 ± 1.6 mm; ulnar styloid, 0.8 ± 1.1 mm; and DRUJ, 3.1 ± 0.9 mm. Two of 11 ulnar styloid pins and 1 of 11 lunotriquetral pin directly penetrated the DSBUN, whereas 4 of 11 ulnar styloid pins, 3 of 11 fifth metacarpal base pins, and 2 of 11 lunotriquetral pins were directly adjacent to the DSBUN. There was an increased overall risk of DSBUN injury (risk of direct injury and risk of adjacent pin) with pinning of the ulnar styloid compared with fifth metacarpal neck and DRUJ pinning., Conclusions: The current study demonstrates the risk of iatrogenic injury to the DSBUN with percutaneous pinning of the ulnar styloid, lunotriquetral joint, and fifth metacarpal base., Clinical Relevance: We recommend identifying and protecting the nerve to mitigate the risk of iatrogenic injury when performing ulnar-sided pinning of structures from the ulnar styloid to the fifth metacarpal base., (Copyright © 2016 American Society for Surgery of the Hand.

Background: Review of the recent literature suggests substantial use of the Internet by patients seeking health care information despite questionable accuracy and readability of information presented on some websites. The purpose of our study was to assess the accuracy, quality, and readability of online information regarding trigger finger., Methods: Three terms ("trigger finger", "stenosing tenosynovitis", and "finger locking") were used to query three Internet search engines to evaluate websites regarding information about trigger finger. Three hand surgery fellows independently assessed website accuracy and quality using standardized scoring criteria. The Fleisch-Kincaid reading grade level score was used to assess website readability. Website authorship and commercial association were also noted., Results: Sixty-nine unique websites were assessed. Internet information obtained using the search term "stenosing tenosynovitis" was written at a significantly higher reading level than information found using "finger locking" or "trigger finger". Website quality and accuracy were both significantly better in websites authored by physicians compared to websites authored by non-physicians. However, website accuracy was significantly poorer in websites featuring commercial association. Additionally, websites presenting information written below the 8(th) grade reading level demonstrated poorer accuracy., Conclusions: Search term has a significant effect on the readability of online information regarding trigger finger. Despite the terminology used in searches, most websites are largely inaccurate and may not be easily understandable by the general population. This demonstrates a substantial barrier to accessing accurate health care information and may impact patient outcomes. Hand surgeons should direct patients towards websites presenting accurate information with easily readable content.

Purpose: To analyze orthopaedic resident case log data to report temporal trends in performing arthroscopic procedures and to assess variability in arthroscopic case volume among residents., Methods: Accreditation Council for Graduate Medical Education orthopaedic surgery resident case logs were reviewed from 2007 to 2013. The mean number of wrist, elbow, shoulder, knee, and ankle arthroscopic procedures performed by graduating residents was analyzed. The median number of arthroscopic procedures reported by the 70th and 30th percentiles of graduating residents (by arthroscopic case volume) was also recorded. Temporal trends were assessed using a linear regression model., Results: From 2007 to 2013, there were significant increases in the mean number of wrist (5.8 to 6.3; P = .038), elbow (2.5 to 3.2; P < .001), shoulder (93.5 to 133.8; P < .001), knee (170.6 to 185.1; P = .011), and ankle (5.8 to 7.4; P < .001) arthroscopies performed per resident. Residents in the 70th percentile of caseload performed significantly more wrist (7 v 2; P < .001), elbow (3.3 v 1; P < .001), shoulder (134.1 v 70.6; P < .001), knee (205 v 128.7; P < .001), and ankle (7.9 v 2.9; P < .001) arthroscopies than residents in the 30th percentile., Conclusions: Our findings indicate that arthroscopic caseload is increasing among orthopaedic residents. However, resident experience performing arthroscopic procedures is substantially disparate. Although the educational implications of this disparity are not well understood, our findings may aid in efforts to optimize arthroscopic training during orthopaedic residency., (Copyright © 2016 Arthroscopy Association of North America.

Background: The objective of this study was to compare the mechanical performance of 4 different constructs for fixation of oblique scaphoid fractures., Methods: Twenty-eight synthetic scaphoids underwent an oblique osteotomy along the dorsal sulcus. Each was randomly assigned to fixation by 1 of 4 methods: two 1.5-mm headless compression screws, one 2.2-mm screw, one 3-mm screw, or a 1.5-mm volar variable-angle plate. After fixation, scaphoids were potted at a 45° angle and loaded at the distal pole by a hydraulically driven mechanical testing system plunger until the fixation failed. Excursion and load were measured with a differential transformer and load cell, respectively. From these data, the stiffness, load-to-failure, and maximum displacement of each construct were calculated., Results: The 2.2-mm screw demonstrated the highest stiffness and the two 1.5-mm screws had the lowest. However, there were no significant differences among the fixation methods in terms of stiffness. Both 2.2- and 3-mm screw constructs had significantly higher loads-to-failure than two 1.5-mm screws. The maximum load for the plate approached, but did not achieve, statistical significance compared with the 1.5-mm screws. There was no significant difference among constructs in displacement., Conclusions: All constructs demonstrated similar mechanical properties that may provide sufficient stability for effective clinical use. Given their significantly higher loads-to-failure, a 2.2- or 3-mm screw may be superior to two 1.5-mm screws for fixation of unstable scaphoid fractures. The volar plate did not have superior mechanical characteristics to the compression screws.

The application of an artificial dermal matrix (Integra Life Sciences, Plainsboro, NJ) in the management of substantial burn injuries has been extensively documented. Use of an artificial dermal matrix has resulted in excellent outcomes and is free of the morbidity associated with harvesting free-tissue flaps. However, coverage of bony defects where the periosteum has been removed is often challenging. In the current report, we present a case wherein the use of an acellular synthetic dermis combined with split-thickness skin grafting resulted in successful coverage of a tibial defect following resection of an osteochondroma., (© The Author(s) 2015.)

Background: Mastery in performing carpal tunnel release (CTR) and hand fracture procedures is an essential component of orthopaedic residency training., Objective: To assess orthopaedic resident case log data for temporal trends in CTR and hand fracture cases and to determine the degree of variability in case volume among residents., Methods: Accreditation Council for Graduate Medical Education orthopaedic surgery resident case logs were reviewed for graduation years 2007 through 2014. Annual data regarding the mean number of CTR and hand fracture/dislocation procedures were recorded, as well as the median number of procedures reported by the top and bottom 10% of residents (by case volume). Temporal trends were assessed using linear regression modeling., Results: There was no change in the mean number of CTRs performed per resident. Over the 8-year period, the top 10% of residents performed a significantly greater number of CTRs than the bottom 10% (62.1 versus 9.3, P < .001). Similarly, no change was noted in the mean number of total hand fracture/dislocation cases performed, with the top 10% of residents performing significantly more hand fracture cases than the bottom 10% (47.1 versus 9.3, P < .001)., Conclusions: Our results indicate no change in CTR and hand fracture caseload for orthopaedic residents. However, as resident experience performing both procedures varies significantly, this variability likely has important educational implications.

Background: The purpose of this study is to evaluate patient's perceptions of physician reimbursement for the most commonly performed surgery on the hand, a carpal tunnel release (CTR)., Methods: Anonymous physician reimbursement surveys were given to patients and non-patients in the waiting rooms of orthopaedic hand physicians' offices and certified hand therapist's offices. The survey consisted of 13 questions. Respondents were asked (1) what they thought a surgeon should be paid to perform a carpal tunnel release, (2) to estimate how much Medicare reimburses the surgeon, and (3) about how health care dollars should be divided among the surgeon, the anesthesiologist, and the hospital or surgery center. Descriptive subject data included age, gender, income, educational background, and insurance type., Results: Patients thought that hand surgeons should receive $5030 for performing a CTR and the percentage of health care funds should be distributed primarily to the hand surgeon (56 %), followed by the anesthesiologist (23 %) and then the hospital/surgery center (21 %). They estimated that Medicare reimburses the hand surgeon $2685 for a CTR. Most patients (86 %) stated that Medicare reimbursement was "lower" or "much lower" than what it should be., Conclusion: Respondents believed that hand surgeons should be reimbursed greater than 12 times the Medicare reimbursement rate of approximately $412 and that the physicians (surgeons and anesthesiologist) should command most of the health care funds allocated to this treatment. This study highlights the discrepancy between patient's perceptions and actual physician reimbursement as it relates to federal health care. Efforts should be made to educate patients on this discrepancy.

There is growing concern that the readability of online orthopaedic patient education materials are too difficult for the general public to fully understand. It is recommended that this information be at the sixth grade reading level or lower. This study compared the readability of shoulder and elbow education articles from the American Academy of Orthopaedic Surgeons (AAOS) and American Society for Surgery of the Hand (ASSH) websites. Seventy-six patient education articles from the AAOS and ASSH concerning shoulder and elbow disorders were evaluated. Each article was assessed for the number of years since its last update, word count, percentage of passive sentences, Flesch Reading Ease score, Flesch-Kincaid grade level, Simple Measure of Gobbledygook (SMOG) grade, and New Dale-Chall grade level. Only one article was at or below the sixth grade reading level. The AAOS and ASSH articles had the following respective scores: a mean Flesch Reading Ease score of 54.3 and 51.8, Flesch-Kincaid grade level of 9.4 and 10.3, SMOG grade of 8.5 and 9.4, and New Dale-Chall grade of 10.4 and 11.0. Articles from the AAOS were longer (p < 0.001), had a lower percentage of passive sentences (p < 0.001), and were more recently updated (p = 0.02) than their ASSH counterparts. Higher percentages of passive sentences were found to correlate with more difficult readability. Patient education materials regarding the shoulder and elbow on the AAOS and ASSH websites have readability scores above the recommended reading level. These may be too challenging for the majority of patients to read and consequently serve as a barrier to proper patient education. Reducing the percentage of passive sentences may serve as a novel target for improving readability.

Background: Fractures and dislocations of the proximal interphalangeal (PIP) joint of the fingers are among the most common causes of injury in the hand. Objective assessment of the kinematic alterations occurring when the supporting structures are disrupted is critical to obtain a more accurate indication of joint stability., Methods: An in vitro cadaver model of the hand was used to evaluate the kinematics of the PIP joint in the finger during active unrestrained flexion and extension. The kinematics of the PIP joint following progressive disruption of the main supporting structures was measured using an optical tracking system and compared with those in the intact joint., Results: Flexion of the intact PIP joint was associated with joint compression, volar displacement, and rotational movements. Release of the main soft-tissue stabilizers and 30 % of volar lip disruption resulted in substantial alteration of several kinematic variables. The normalized maximum dorsal/volar translation was 0.1 ± 1.3 % in the intact group and 14.4 ± 11.3 % in the injured joint., Conclusions: In the intact PIP joint, rotations and translation are strongly coupled to the amount of joint flexion. Gross instability of the PIP joint occurs when disruption of the collateral ligaments and volar plate is accompanied by resection of at least 30 % of volar lip of the middle phalanx. Collateral ligament injuries, volar plate injuries alone, and fractures at the volar base of the middle phalanx that involve less than 30 % of the articular surface are unlikely to result in gross instability and may be managed effectively with non-operative treatments.

Background The pronator quadratus (PQ) muscle is an important and commonly encountered structure in surgery of the wrist. A thorough understanding of the anatomy of the PQ and the anterior interosseous nerve (AIN), which innervates the PQ, is important, particularly during distal radius fracture osteosynthesis and distal AIN transfer to deep branch of the ulnar nerve. Furthermore, there is a paucity of literature regarding sex differences in the morphology of these structures. We describe the morphology of the PQ and AIN and compare PQ and AIN findings in male and female specimens. Methods Twenty-five cadaveric upper extremities underwent loupe-aided dissection of the volar forearm with identification of the AIN and PQ. A digital photograph taken perpendicular to the volar surface of the forearm was used to measure the PQ and assess AIN morphology using ImageJ (National Institutes of Health; Bethesda, MD). Comparisons between male and female specimens were performed. Results Of the 25 specimens, 84% appeared as a single trapezoidal muscle bundle, with the remaining 16% demonstrating a double-bundle morphology. The PQ was a mean 3.8 ± 0.5 cm in radial-ulnar width and 4.6 ± 0.7 cm in proximal-distal length with a mean thickness, area, and volume of 0.6 ± 0.2 cm, 18.2 ± 4.8 cm(2), and 10.5 ± 3.7 cm(3), respectively. The PQ branch of the AIN was a mean 3.8 ± 1.1 cm long and had a mean diameter of 1.4 ± 0.2 mm. Male specimens demonstrated significantly greater radial-ulnar width (p = 0.005), area (p = 0.006), and volume (p = 0.033) of the PQ, as well as a greater distance from the radial styloid to the distal arborization of the AIN (p = 0.005) compared with female specimens. Conclusions The current study informs hand surgeons of the morphologic variability and sexual dimorphism of the PQ and AIN and may help guide operative planning.

Perilunate dislocations and fracture dislocations are the result of an axial load with hyperextension and ulnar deviation of the wrist, combined with intercarpal supination. Prompt treatment injuries is essential. There is a high rate of missed or incorrect diagnosis. In the past, closed management was recommended. These methods proved to be ineffective. Current research and data show better results with anatomic restoration of carpal alignment and direct ligament repair. A combined dorsal and volar approach is preferred. This article reviews the current literature and discusses the surgical techniques to restore carpal alignment and repair the scapholunate interosseous ligament., (Copyright © 2015 Elsevier Inc.

Background: To review the results of plating of various fracture patterns of proximal ulna fractures including isolated olecranon fractures, olecranon fractures combined with a coronoid fracture, and olecranon fractures combined with a coronoid and radial head fracture., Materials and Methods: The study included 38 patients with either an isolated olecranon fracture or combined injuries, all treated with open reduction and internal fixation of the olecranon. Other procedures were performed as needed, including radial head fixation or arthroplasty, fixation of the coronoid, and repair of the lateral collateral ligament complex. There were 27 men and 11 women with an average age of 49 years. Clinical and radiographic assessment was obtained at an average follow-up time of 15 and 8.4 months, respectively., Results: All fractures healed within 5 months. The average arc of ulnohumeral motion was 91° (range 0°-140°); average pronation-supination arc was 128° (range 0°-180°). Subgroup analysis showed a statistically significant lower rotational motion arc in patients with associated radial head (73°) or coronoid fractures (68°) compared to isolated olecranon fractures. All other parameters including ulnohumeral motion, complication rate, and revision rate were similar among the groups., Conclusions: A stable, functional elbow can be restored in most patients with proximal ulna fractures treated with open reduction and internal fixation. Loss of full flexion is likely with high-energy trauma, complex fracture patterns, and concomitant injuries. Fracture patterns involving the coronoid and/or the radial head are associated with restricted forearm rotation., Level of Evidence: III.
