Objectives: Participation in National Collegiate Athletic Association (NCAA) football is at an all-time high. This population experiences a substantial injury burden with many of these injuries affecting the upper extremities. The NCAA has adopted a data-driven decision-making process when providing recommendations for protecting player safety. The purpose of this study was to describe the epidemiology of hand and wrist injury in NCAA football in an effort to provide meaningful data for tailoring effective injury prevention strategies. Methods: An epidemiologic study utilizing the NCAA Injury Surveillance Program (NCAA-ISP) database was performed to investigate rates and patterns of hand and wrist injury in NCAA varsity football teams participating in the NCAA-ISP from 2009 to 2014. Descriptive statistics were used to present demographic data. Injury rates were calculated per 1000 athlete-exposures (AEs) using statistical cross-referencing between injury-level and event-level data. Injury mechanism and severity, as measured by time-loss from play, were determined and compared between exposure factors such as player position, player seniority, and practice versus game setting. Results: 725 hand and wrist injuries were captured in 899,225 AEs. The observed practice hand and wrist injury rate was 0.51 injuries per thousand AEs, which was significantly lower than the game injury rate of 3.60 (p < 0.01). Comparing player demographics for injuries sustained during practice as opposed to game time revealed significant differences based on player year, player position, activity performed at the time of injury, and mechanism of injury (p < 0.01, Figure 1). Player-on-player contact was the most common injury mechanism reported with blocking being the most common activity at injury. Of all sustained injuries, 71.4% resulted in no time loss from competition whereas 9.8% of injuries resulted in greater than 7 days of time loss. On average, fracture resulted in the greatest time loss from competition (8.3 ± 24.0 days for injuries sustained in practice setting, 7.7 ±15.8 days for injuries sustained in game setting). When comparing injury by location, hand injury resulted in greater time loss (3.7 ± 15.1, 4.4 ± 13.8) than to nail/subungual (0±0, 0±0), finger (1.6 ± 6.7, 1.1 ± 4.2), and wrist injury (1.2 ± 3.8, 1.8 ± 4.9). Conclusion: This study characterizes the incidence of NCAA football hand and wrist injuries in both practice and game settings and demonstrates the relatively low rate of injuries leading to loss of playing time. Hand and wrist injury was found to be significantly more common in games when compared to practice. Offensive linemen were the most commonly affected players in the cohort, with most injuries occurring during game time compared to practice. This study provides valuable prognostic data regarding expected time loss from play on a per injury pattern basis. Further investigation on specific injury subtypes and expected time loss as a result of these injures would provide trainers, players, and coaches with useful information on an expected post-injury recovery and rehabilitation timeline.

Wrist fusions and other key issues in upper limb-related surgery
Our study aimed to report the short-term outcomes of patients who underwent partial ulnar head replacement and distal radial ulnar joint interposition arthroplasty. From 2012 to 2016, nine patients underwent this procedure with mean follow-up of 27 months (range 12–55). Seven of the nine patients had previously undergone surgical intervention on the ipsilateral wrist. The procedure resulted in substantial improvements in pain and function. Mayo Wrist Score improved from 37 preoperatively to 73 postoperatively, and six patients achieved a good or excellent outcome. Visual analogue pain scores decreased from 7 preoperatively to 1 postoperatively. Grip improved from 20 kg preoperatively to 30 kg postoperatively. There was no significant change in wrist range of motion. Two patients underwent revision surgery to improve wrist motion. We conclude that over short-term follow-up the procedure provides a feasible option for distal radial ulnar joint arthritis. Level of evidence: IV
» Ulnar-sided wrist pain encompasses a variety of pathologies including arthritis, tendinopathy, ligament injuries, and instability. » A careful physical examination can narrow the differential diagnosis, and adjunctive imaging may prove useful to confirm clinical suspicion. » The mainstay of nonoperative treatment is immobilization, hand therapy, and corticosteroid injections; surgical intervention is dictated by the specific pathology identified, recognizing that multiple pain generators may be present. » In the absence of distal radioulnar joint instability, when indicated, peripheral capsular repair of the triangular fibrocartilage complex may be an effective procedure for relieving pain. If instability is noted, foveal repair is advocated to restore stability. » Treatment of distal radioulnar joint arthritis continues to evolve as new implants and techniques emerge. » Ulnar shortening osteotomy, when indicated, can be a reliable surgical option to reduce pain and improve function.
Epidemiology of Hand and Wrist Injuries in NCAA Men’s Football: 2009–2010 to 2013–2014
Background: Participation in National Collegiate Athletic Association (NCAA) football is at an all-time high. This population of athletes experiences a substantial injury burden, with many injuries affecting the upper extremities. Purpose/Hypothesis: The purpose of this study was to describe the epidemiology of hand and wrist injuries in college football players from the academic years 2009–2010 to 2013–2014. We hypothesized that variables such as event type (practice vs game), mechanism of injury, and player position would have an effect on the injury incidence. Study Design: Descriptive epidemiological study. Methods: An epidemiological study utilizing the NCAA Injury Surveillance Program was performed to investigate rates and patterns of hand and wrist injuries in participating varsity football teams from 2009–2010 to 2013–2014. Results: A total of 725 hand and wrist injuries were captured in 899,225 athlete-exposures. The observed practice injury rate was 0.51 injuries per 1000 athlete-exposures, compared with a game injury rate of 3.60 ( P < .01). Player-on-player contact was the most common injury mechanism reported, with blocking being the most common activity at the time of injury. Offensive linemen were most likely to experience an injury. Of all injuries sustained, 71.4% resulted in no time loss from competition, whereas 9.8% of injuries resulted in longer than 7 days of time loss. A fracture resulted in the greatest time loss from competition (mean ± SD, 8.3 ± 24.0 days; median, 0 days [range, 0-148 days] for injuries sustained in a practice setting) (mean ± SD, 7.7 ± 15.8 days; median, 0 days [range, 0-87 days] for injuries sustained in a game setting). Conclusion: Hand and wrist injuries were found to be significantly more common in games when compared with practices. This study provides valuable prognostic data regarding expected time loss on a per-injury pattern basis. Further investigation on specific injury subtypes and expected time loss as a result of these injures would provide trainers, players, and coaches with useful information on an expected postinjury recovery and rehabilitation timeline.
Comparison of In Situ Versus Subcutaneous Versus Submuscular Transpositions in the Management of McGowan Stage III Cubital Tunnel Syndrome
Background: The objective of the study was to evaluate and compare the clinical outcomes of in situ decompression with subcutaneous and submuscular transpositions for surgical management of advanced (McGowan stage III) cubital tunnel syndrome (CuTS). Methods: A retrospective review of patients in our institution undergoing primary surgery for CuTS from February 1989 to May 2009 was performed. Patients with advanced CuTS with a minimum of 12 months of follow-up without any previous bony or soft tissue procedures around the elbow were included. Seventy-four patients underwent 80 primary ulnar nerve surgeries. Patients’ demographics, presenting symptoms, physical examination, electrodiagnostic findings, and perioperative complications were recorded. Primary surgical techniques were compared and the risk factors for revision surgery were assessed. Results: Of the 80 surgical procedures, there were 17 decompressions (21%), 47 subcutaneous transpositions (59%), and 16 submuscular transpositions (20%). Fifty-two percent of patients had resolution of their symptoms after primary surgery. The overall complication rate after primary surgery was 12.5%. Nineteen patients (24%) had revision surgery at a median of 30 months after their primary procedure. Eight patients (42%) had symptomatic improvement after revision surgery. Patients with their dominant extremity affected, static 2-point discrimination (S2PD) greater than 10 mm, and age less than 50 years at presentation had a higher rate of revision surgery. Three patients had a second revision surgery and neurolysis for persistent symptoms. Conclusions: The overall revision rate in advanced CuTS was 24%. Forty-two percent of patients had reported subjective symptomatic improvement after revision surgery. Younger age at presentation and a greater S2PD were associated with a higher rate of revision surgery.
A Versatile Protocol for Studying Anterior Cruciate Ligament Reconstruction in a Rabbit Model
* The wrist maintains stability through complex articulations of the carpal bones, dependent upon intrinsic and extrinsic ligaments. * Injury to the scapholunate interosseous ligament may lead to dissociative carpal instability, abnormal carpal kinetics, and sometimes arthritis. * The kinematics, kinetics, and self-stabilizing role of the tendons and their influence on the scapholunate interosseous ligament continue to be studied. * Critical to successful treatment of scapholunate interosseous ligament injuries is timely and complementary therapy. * There is currently no gold standard for a treatment algorithm for this condition.
Scapholunate Ligament Internal Brace 360 Tenodesis (SLITT) Procedure: A Biomechanical Study
Background Twelve paired fresh frozen cadaveric wrists were randomized to a 360-degree tenodesis repair group or the 360-degree tenodesis repair with an internal brace (suture tape) construct. Case Description The specimens were preloaded to 5 N and subsequently biomechanically loaded to failure, at a rate of 0.1 mm/s on a jig that allowed for axial load. The maximum load and mode of failure were recorded. Load to failure in the 360 tenodesis group with internal brace was 283.47 ± 100.25 N, compared with the 360 tenodesis group only, whose yield strength was 143.61 ± 90.54 N. The mode of failure within the internal brace construct was either through knot slippage, graft disruption, or bone separation from strength testing construct. The 360 tenodesis group tended to fail via graft slippage or graft rupture. Literature Review The management of scapholunate instability can be a difficult problem to treat. Traditionally, many of the surgical reconstructions have focused upon dorsal ligament reconstruction with Kirschner (K) wire fixation. This results in prolonged immobilization of the wrist with varied outcomes, in part due to the multiaxial instability that may persist due to concomitant volar ligament disruption. To address this instability, surgical techniques have been devised that address both the volar and dorsal ligament injuries. Clinical Relevance Scapholunate reconstruction with a 360-degree tenodesis and internal brace augmentation (SLITT procedure) provided superior biomechanical stability than tenodesis alone.
