Management of Hand and Wrist Injuries in NCAA Division I Football Players From a Single Institution: Factors Associated With Epidemiology, Surgical Intervention, and Return to Play.

Background: Upper extremity injuries account for approximately 16.9% of football injuries in the National Collegiate Athletic Association (NCAA). Purpose: To determine the epidemiology, management, and outcomes of hand/wrist injuries in collegiate football athletes so as to identify factors associated with surgical intervention and delayed return to play (RTP). Study Design: Descriptive epidemiology study. Methods: We retrospectively reviewed hand/wrist injuries that occurred within a single NCAA Division I football team from January 1, 2003, to December 31, 2020. Data analyzed included player position, college seniority, injury characteristics, injury management, surgical procedures performed, and timing of RTP. A univariate analysis was performed to identify factors associated with increased risk for surgical intervention and delayed (>21 days) RTP after hand and wrist injury in this cohort. Results: Overall, 124 patients with 168 hand/wrist injuries were identified (9.9 wrist/hand injuries per year). Sprain of the thumb metacarpophalangeal (MCP) joint ulnar collateral ligament (UCL) was the most common diagnosis (19.6%). Surgery was required in 22% of injuries, with injury of the UCL of the thumb MCP joint (8/37) being the most common indication. Injuries occurring during competitive games (odds ratio = 4.29; 95% CI, 1.2-15.9) were associated with an increased risk for surgery. Most (70%) injuries did not lead to time missed from football, whereas the remaining 30% resulted in an average of 33 ± 36 days missed. Conclusion: Over 17 athletic seasons, the annual incidence of hand and wrist injury in these NCAA Division I football players was 9.9 injuries per year, with 22% requiring surgical treatment. Injury to the UCL of the thumb MCP joint was the most common injury and indication for surgery, and 30% of injuries resulted in approximately 1 month lost. Injuries sustained in games were associated with operative management and delayed RTP.

Harms Reporting in Randomized Controlled Trials Underpinning the American Academy of Orthopaedic Surgeons Clinical Practice Guidelines for Distal Radius Fractures.

PURPOSE: The purpose of this study was to measure the harms-related reporting among randomized controlled trials (RCTs) cited as supporting evidence for the American Academy of Orthopaedic Surgeons clinical practice guidelines regarding the management of distal radius fractures. METHODS: We adhered to the guidance for reporting metaresearch and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines throughout the course of this investigation. We used the American Academy of Orthopaedic Surgeons clinical practice guidelines for distal radius fractures available on Orthoguidelines.org. A linear regression analysis was conducted to model the relationship between the year of publication and the total Consolidated Standards of Reporting Trials percentage adherence over time. RESULTS: Thirty-five RCTs were included in the final sample. The average number of Consolidated Standards of Reporting Trials Extension for Harms items adequately reported across all included RCTs was 9.2 (9.2/18, 50.9%). None of the included trials adequately reported all 18 items. Ten items had a compliance of more than 50% (10/18, 55.6%), 4 items had a compliance of 20%-50% (4/18, 22.2%), and 4 items had a compliance of less than 20% (4/18, 22.2%). The results of the linear regression model showed no significant improvement in Consolidated Standards of Reporting Trials Harms reporting over time. CONCLUSIONS: Adverse events are incompletely reported among RCTs cited as supporting evidence for American Academy of Orthopaedic Surgeons clinical practice guidelines for the management of distal radius fractures. CLINICAL RELEVANCE: Given our findings, specific attention should be paid to improving the standardization of the classification of adverse events to facilitate ease in the reporting process.

Lunate Revascularization With Temporary Internal Radiocarpal Spanning Fixation for Kienböck Disease.

BACKGROUND: The goal in the treatment of stages II and III Kienböck disease is to restore lunate vascularity and halt the progression of avascular necrosis. METHODS: We report the outcomes for patients with stages II and III Kienböck disease treated with fourth extensor compartment artery vascularized bone grafting and temporary radiocarpal spanning internal fixation. Nine patients with a mean age of 28.8 years were included. Mean clinical and radiographic follow-up were 4.9 and 1.9 years, respectively. RESULTS: Six patients had no change in Lichtman stage, 2 patients regressed 1 stage, and 1 patient progressed 1 stage. Mean postoperative quick disabilities of the arm, shoulder, and hand (QuickDASH) was 17.4. Mean postoperative visual analogue pain scale (VAS) was 1.8. Patients under age 25 trended toward improved clinical outcomes compared with patients over age 25. Two patients, aged 33 and 65, underwent proximal row carpectomy at a mean 30.5 months postoperatively. CONCLUSIONS: In conclusion, the use of local vascularized bone graft with temporary internal radiocarpal spanning fixation provides a treatment option with outcomes comparable to existing literature with benefits inherent to internal immobilization.

Single Versus Dual Headless Compression Screw Fixation of Scaphoid Nonunions: A Biomechanical Comparison.

BACKGROUND: Management of scaphoid nonunions with bone loss varies substantially. Commonly, internal fixation consists of a single headless compression screw. Recently, some authors have reported on the theoretical benefits of dual-screw fixation. We hypothesized that using 2 headless compression screws would impart improved stiffness over a single-screw construct. METHODS: Using a cadaveric model, we compared biomechanical characteristics of a single tapered 3.5- to 3.6-mm headless compression screw with 2 tapered 2.5- to 2.8-mm headless compression screws in a scaphoid waist nonunion model. The primary outcome measurement was construct stiffness. Secondary outcome measurements included load at 1 and 2 mm of displacement, load to failure for each specimen, and qualitative assessment of mode of failure. RESULTS: Stiffness during load to failure was not significantly different between single- and double-screw configurations (P = .8). Load to failure demonstrated no statistically significant difference between single- and double-screw configurations. Using a qualitative assessment, the double-screw construct maintained rotational stability more than the single-screw construct (P = .029). CONCLUSIONS: Single- and double-screw fixation constructs in a cadaveric scaphoid nonunion model demonstrate similar construct stiffness, load to failure, and load to 1- and 2-mm displacement. Modes of failure may differ between constructs and represent an area for further study. The theoretical benefit of dual-screw fixation should be weighed against the morphologic limitations to placing 2 screws in a scaphoid nonunion.

Utilizing Google Trends to Track Online Interest in Elective Hand Surgery During the COVID-19 Pandemic.

Introduction Elective hand surgery encompasses a large volume of orthopaedic cases annually. Carpal tunnel syndrome, ganglion cysts, and trigger digits are some of the most common pathologies treated by hand surgeons. In the midst of the COVID-19 pandemic, patient's interest in elective hand surgery for these conditions is uncertain. The objective of this study is to use Google Trends to track online interest in elective hand surgery in the United States during the COVID-19 pandemic. Methods Online search trends regarding elective orthopaedic hand surgery were obtained via Google Trends from November 2019 to November 2020. Three common hand pathologies in lay terms ("carpal tunnel," "'ganglion cyst' + 'wrist cyst,'" and "trigger finger") and three hand surgery-specific keywords ("hand surgery," "carpal tunnel surgery," and "trigger finger surgery") were used as search terms. The search volume index (SVI) graphs for the United States for both sets of search terms were then generated from the Google Trends data and compared to the seven-day average of new COVID-19 cases per day as reported by the CDC. A separate SVI graph was then created for the search term "coronavirus" and was compared against both sets of search terms as above. Results Search trends for all elective hand pathologies and surgery-specific keywords remained constant from November 2019 to the beginning of March 2020 and then decreased significantly within a one-month period following the peak in COVID-19 cases the week of March 15, 2020. Search trends for these keywords increased to baseline levels over the next few months. The search trend for "coronavirus" demonstrated a small search volume index peak of 13 during January 2020 followed by the maximum peak of 100 during the week of March 15, 2020, corresponding to the decrease in search trends of elective hand surgery at that time. Conclusions Online interest in elective hand surgery remained constant prior to the COVID-19 pandemic; however, there was a marked decrease in search trends of elective hand surgery with the rise in daily reported COVID-19 cases, suggesting that patient's interest in elective hand surgery decreased with the onset of the pandemic.

The management of clenched fist injuries with local anaesthesia and field sterility.

Clenched fist injury is associated with a high risk of infectious complications and is commonly managed with formal irrigation and debridement in the operating theatre. The purpose of this study was to determine outcomes associated with irrigation and debridement of clenched fist injuries under local anaesthesia using field sterility outside the operative theatre. In this single centre study, 232 patients were identified with clenched fist injury and 210 were treated with a standard protocol beginning with administration of intravenous antibiotics and then irrigation and debridement at the bedside. Primary outcome measures were the need for repeat debridement and complications. Secondary outcome measures included factors associated with the need for repeat debridement. Fifteen of the 210 patients (7%) required repeat debridement. Patients with cultures positive for gram-negative organisms had a significantly increased risk of repeat debridement. Irrigation and debridement under local anaesthesia using field sterility results in an acceptably low risk of complications or need for repeat debridement.Level of evidence: IV.

Ulnocarpal-Spanning Plate Fixation as a Novel Technique for Complex Distal Ulna Fracture: A Case Report.

CASE: The patient was a 60-year-old woman with a comminuted, open distal radius and distal ulna metadiaphyseal fracture. After fixation of the distal radius, the distal ulna was unstable and crepitant with rotation and anteroposterior translation. Because of limited bone stock and poor soft tissue, we spanned the distal ulna using a wrist spanning plate. This was removed at 6 weeks postoperatively. She healed and was satisfied with her outcomes. CONCLUSION: This case describes the original use of a wrist spanning plate for a complex distal ulna fracture. Ulnocarpal-spanning plate fixation provides an alternative to traditional methods of fixation.

Proximal Radius Fractures in Children.

Fractures of the proximal radius represent 5% to 10% of all elbow fractures in children. These fractures have many treatment options and have a high risk of complication, particularly loss of forearm rotation. Nonsurgical management of minimally displaced radial neck fractures produces excellent results in most patients. For displaced fractures, numerous methods of closed and percutaneous reduction have been proposed, whereas open reduction has been associated with particularly poor outcome. Many additional factors, including fracture angulation, patient age, associated injury, articular involvement, and internal fixation, may lead to worse outcomes. Because the literature is limited to retrospective case series, few studies provide high-level evidence to guide the treatment of pediatric proximal radius fractures; however, certain management principles have been established that are reviewed here.

Redefining Zone II: Anatomy of the Flexor Digitorum Superficialis Insertion.

BACKGROUND: Flexor zone II is defined as the region spanning the proximal aspect of the A1 pulley to the insertion of the flexor digitorum superficialis (FDS) tendon. Descriptions of the FDS insertion are inconsistent in the literature, but zones of injury are frequently determined with reference to superficial landmarks. The purpose of this study was to describe the footprint of the FDS insertion and define its relationship to the proximal interphalangeal (PIP) skin crease. METHODS: The FDS insertion on the index, middle, ring, and small fingers was dissected in 6 matched pairs of fresh-frozen cadaveric hands. A Kirschner wire was used to mark the level of the PIP skin crease on bone before measurements of the FDS footprint and its position relative to the PIP skin crease were made using digital calipers. RESULTS: The radial and ulnar FDS slips inserted a mean distance of 3.22 mm from the distal aspect of the PIP skin crease and varied by digit. The mean distal extent of the FDS insertion was 8.29 mm. The mean length of the insertion of each FDS slip was 5.15 mm and the mean width was 1.9 mm. CONCLUSIONS: The radial and ulnar FDS slips insert on average 3.22 mm distal to the PIP skin crease and vary by digit. Knowledge of the FDS insertion is clinically relevant when differentiating between flexor zone I and zone II injuries, planning surgical approaches to the finger, and in guiding patient expectations for surgery given the variability in outcome based on zone of injury.

Risk of Knee Sepsis After Treatment of Open Tibia Fractures: A Multicenter Comparison of Suprapatellar and Infrapatellar Approaches.

OBJECTIVES: The suprapatellar approach for medullary nailing of the tibia is increasing. This requires intra-articular passage of instruments, which theoretically places the knee at risk of postoperative sepsis in the setting of open fracture. We hypothesized that the risk of knee sepsis is similar after suprapatellar or infrapatellar nailing of open tibia fractures. DESIGN: Retrospective, multicenter. SETTING: Three urban level 1 trauma centers. PATIENTS: All patients treated with medullary nailing for open diaphyseal tibia fractures (OTA 42) from 2009 to 2015. Patients younger than 18 years of age and with less than 12 weeks of follow-up were excluded. We identified 289 fractures in 282 patients. INTERVENTION: Suprapatellar (SP) or infrapatellar (IP) medullary nailing of open tibia fractures. MAIN OUTCOME MEASUREMENT: Occurrence of ipsilateral knee sepsis, defined as presence of a positive culture from knee aspiration or arthrotomy. Deep infection requiring operative debridement, superficial infection requiring antibiotic therapy alone, and all-cause reoperation were also recorded. RESULTS: IP nailing was used for 142 fractures. There were 20 infections (14.1%), of which 14 (9.8%) were deep. Fourteen tibias (9.8%) required reoperation for noninfectious reasons for 28 total reoperations (19.7%). SP nailing was used in 147 fractures. There were 24 infections (16.2%), of which 16 (10.8%) were deep. Fourteen additional tibias (9.5%) required reoperation for noninfectious reasons for a total of 30 reoperations (20.4%). There were no differences in the rates of infection, deep infection, or reoperation between groups. There were 2 cases of knee sepsis after SP nailing (1.4%) but zero cases after IP nailing (P = 0.5). CONCLUSIONS: There was no significant difference in the rate of knee sepsis with SP or IP approaches. The risk of knee sepsis after SP nailing of open fractures is low, but present. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Use of a Defined Surgical Approach for the Debridement of Open Tibia Fractures.

OBJECTIVES: To determine whether a defined approach for debridement of open tibia fractures would result in no change in reoperation rate, but reduce the need for flap coverage. DESIGN: Prospective cohort study. SETTING: Academic Level 1 trauma center. PATIENTS: A total of 66 patients with 68 open diaphyseal tibia fractures were included. Patients under the age of 18 and with orthopaedic trauma association open fracture classification (OTA-OFC) skin score of 3 were excluded. INTERVENTION: Debridement of the open fracture through direct extension of the traumatic wound or through a defined surgical interval. MAIN OUTCOME MEASUREMENTS: Number of operations. Need for soft-tissue transfer. RESULTS: A total of 47 patients had direct extension of the traumatic wound and 21 patients had a defined surgical approach. The groups had similar proportions of Gustilo-Anderson and OTA-OFC subtypes. The average number of surgeries, including index procedure, per patient was 1.96 in the direct extension group and 1.29 in the defined approach group (P = 0.026). Flap coverage was needed in 9 patients in the direct extension group and no patients in the defined approach group (P = 0.048). CONCLUSIONS: A defined surgical approach to the debridement of open tibia fractures is safe and may reduce the need for flap coverage in select patients. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Fluoroscopically Guided Peritendinous Corticosteroid Injection for Proximal Hamstring Tendinopathy: A Retrospective Review.

BACKGROUND: Proximal hamstring tendinopathy is an uncommon but debilitating cause of posterior thigh pain in athletes subjected to repetitive eccentric hamstring contraction, such as runners. Minimal data exist evaluating treatment options for proximal hamstring tendinopathy. PURPOSE: This retrospective study evaluates the effectiveness of fluoroscopically guided corticosteroid injections in treating proximal hamstring tendinopathy. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Eighteen athletes with 22 cases of magnetic resonance imaging-confirmed proximal hamstring tendinopathy were treated with corticosteroid injection and later contacted to evaluate the efficacy of the injection with the use of a questionnaire. RESULTS: The visual analog score decreased from 7.22 preinjection to 3.94 postinjection (P < .001), level of athletic participation increased from 28.76% to 68.82% (P < .001) at a mean follow-up of 21 months, and 38.8% of patients experienced complete resolution at a mean follow-up of 24.8 months. The mean lower extremity function score at the time of follow-up was 60. CONCLUSION: A trial of fluoroscopically guided corticosteroid injection is warranted in patients presenting with symptoms of proximal hamstring tendinopathy refractory to conservative therapy.

Re-learning curve for conventional total knee arthroplasty following 30 consecutive computer-assisted total knee arthroplasties.

A learning curve for returning to conventional total knee arthroplasty (TKA) after using computer-assisted (CAS) TKA has not yet been established. In this study, the postoperative mechanical axes of the first 30 consecutive CAS TKAs performed by a single surgeon were compared to his subsequent 120 conventionally performed TKAs. A "re-learning curve" of 30 conventional TKAs was necessary to attain an average postoperative mechanical axis statistically indistinguishable from the average CAS mechanical axis (1.99°). This is a trend of which surgeons should be aware when converting from CAS TKA to conventional TKA. As a secondary goal, the authors identify the first clinical parameter, preoperative deviation from neutral mechanical axis, that may potentially serve as a guide for the selective use of CAS in TKA.

Intramuscular dissection of a large ganglion cyst into the gastrocnemius muscle.

Ganglion cysts are lesions resulting from the myxoid degeneration of the connective tissue associated with joint capsules and tendon sheaths. Most common around the wrist joint, ganglion cysts may be found elsewhere in the body, including in and around the knee joint. Uncommonly, ganglion cysts can present intramuscularly. Previous reports document the existence of intramuscular ganglia, often without histologic confirmation. This article describes a case of an intramuscular ganglion cyst in the medial gastrocnemius muscle of a 53-year-old woman. The patient initially presented for discomfort associated with the lesion. Examination was consistent with intramuscular cystic lesion of unknown etiology. Ultrasound and magnetic resonance imaging revealed the origin of the mass at the semimembranosus-gastrocnemius bursa. Because of its location, the mass was initially suspected to be a dissecting Baker's cyst, an uncommon but previously reported diagnosis. The patient underwent surgical excision, and examination of the intact specimen revealed a thin, fibrous, walled cyst with no lining epithelium, which was consistent with a ganglion cyst. To the authors' knowledge, this is the first report in the orthopedic literature of a ganglion cyst dissecting into the gastrocnemius muscle. Because ganglion cysts commonly require excision for definitive treatment and do not respond well to treatment measures implemented for Baker's cysts, including resection of underlying meniscal tears, the authors believe it is important for orthopedic surgeons to be able to distinguish between Baker's and other cysts associated with the knee joint, including ganglion cysts, which may require more definitive treatment.
