Retained or missed foreign bodies are a common complication associated with penetrating wounds. Ideal management includes immediate removal of the foreign material without any further damage to local tissues. However, removal is often difficult if the foreign body is small or has penetrated deeply. In this setting, the emergency room is a suboptimal environment for removal. Ultrasound utilized at the time of removal improved our ability to localize the foreign body, however this requires surgeon familiarity with the equipment. We describe the use of preoperative ultrasound guided foreign body localization with careful topographic skin marking to guide intraoperative foreign body removal with increased yield and obviating the need for ultrasound at the time of removal.

Fractures of the capitellum and trochlea are uncommon fractures of the elbow and can be challenging to treat due to their size, location, and articular nature. Because of their intra-articular nature and predilection toward displacement, these fractures are typically treated operatively. Furthermore, capitellum fractures have high rates of associated injuries, including radial head fractures or lateral collateral ligament injury in ~30% to 60% of patients. In addition to open reduction internal fixation, operative options include fragment excision, arthroscopic assisted reduction and fixation, and elbow arthroplasty. In this article, we undertake a comprehensive literature review of capitellum fractures of the distal humerus, in an attempt to summarize the existing body of evidence and propose areas of future study.

Purpose Trigger finger is a commonly occurring hand condition that presents with symptoms of pain, clicking, locking, and catching of the finger. A common non-operative management option is corticosteroid injection. The purpose of this study was to evaluate the short-term patient response to corticosteroid injections for trigger finger.  Methods The patients of six fellowship-trained orthopedic hand surgeons who underwent a corticosteroid injection for trigger finger between June 2019 and October 2019 were invited to participate in this study. Patients were contacted by phone at one week, two weeks, and three weeks after the injection to complete a questionnaire regarding their pain and triggering symptoms. Medical records were also reviewed to collect basic demographic data. Results A total of 452 patients were included in the study. At the final follow-up, 82.4% of patients reported complete pain relief, 16.3% had partial relief, and 1.2% had no relief from their pain. For their triggering symptoms, 65.9% reported complete triggering relief, 30.4% had partial relief, and 3.5% had no triggering relief. It took an average of 6.6 days following injection for patients to experience complete pain relief, and an average of 8.1 days for patients to experience complete triggering relief. Conclusions This analysis found that most patients experience relief of pain and triggering at three weeks following corticosteroid injection. The majority of patients experienced some pain relief within the first week following corticosteroid injection, while improvement in triggering appeared to lag behind pain relief.

INTRODUCTION/BACKGROUND:Orthopedic instrumentation is generally made as one-size-fits-all. The purpose of this study was to evaluate the effects of hand size and sex on ease of use and injury rates from orthopedic tools and surgical instruments. METHODS:An anonymous 21-item online survey was distributed to orthopedic trainees and attendings. Questions regarding demographics, physical symptoms and treatment, perceptions, and instrument-specific concerns were included. The analysis included statistics comparing responses based on sex, height, and glove size, with significance as p<0.05. RESULTS:There were 204 respondents: 119 female and 84 male. Male and female respondents differed significantly in height (mean difference 5.4 in, p<0.001) and glove size (median size 6.5 size for females, size 8 for males, p<0.001). While 69.8% of respondents reported physical discomfort or symptoms they attributed to their operating instruments, female surgeons were significantly more likely to endorse symptoms (87.3% female vs. 45.2% male, p<0.001). Of those reporting symptoms, 47.7% had undergone treatment, with no significant difference by surgeon sex (p=0.073). Female surgeons were significantly more likely than their male counterparts to have negative attitudes toward orthopedic surgical instruments and to report specific surgical instruments as difficult or uncomfortable to use. CONCLUSION/CONCLUSIONS:Female orthopedic surgeons are more likely than their male counterparts to report physical symptoms attributed to orthopedic surgical instruments, to have negative attitudes toward instruments, and to identify a larger number of common instruments as difficult or uncomfortable to use. Further emphasis on ergonomic instrument design is needed to allow all orthopedic surgeons to operate as safely and effectively as possible.

PURPOSE:Guidelines for sterilization of reusable equipment (eg, arthroscopes, surgical equipment) have recently been established. These guidelines are supported by the U.S. Food and Drug Administration and affect costs for sterilization. The current analysis was undertaken to understand if reusable or disposable endoscopic carpal tunnel release (ECTR) equipment is a less-expensive option. METHODS:An activity-based cost analysis was undertaken to determine the costs of reusable versus disposable equipment for ECTR. Costs of disposable equipment were obtained from manufacturers. Costs of processing reusable equipment including labor, time, cost of operating room time, and sterilization supplies and equipment were obtained from the literature and from recent reports identifying these costs. Infection rates and costs of infection were also factored in. Decision analysis software was used to determine the expected costs of each option (disposable vs reusable). A sensitivity analysis was undertaken on those variables that were determined to have the greatest effect on the overall costs of the procedure and sterilization. RESULTS:Costs for each option when totaled were $917 for disposable and $1,019 for reusable equipment, resulting in cost savings of $102 with disposable equipment. Reusable equipment was the least costly option when the following costs/events occurred: cost of a disposable arthroscope, >$452; cost of disposable ECTR, >$647; costs of operating room time, <$28.63/min; set up time, <6.8 minutes for reusable equipment; and cost of disposable ECTR blade used with reusable equipment, <$160. CONCLUSIONS:When considering the cost of operating room time, preparation, and processing of reusable equipment for ECTR, the disposable equipment for this procedure is less costly.

Introduction/UNASSIGNED:Rock climbing is an increasingly popular sport in the United States. Acute and chronic upper extremity injuries related to rock climbing are frequently reported and include flexor pulley ruptures and hamate stress fractures. Deep space hand infections after indoor rock climbing are a sport-related pathology that has yet to be reported. Our purpose is to describe an acute septic carpal tunnel syndrome following rock climbing at an indoor climbing gym in a patient who required urgent irrigation and debridement. Case Report/UNASSIGNED:A 33-year-old Caucasian male presented with an acute septic carpal tunnel syndrome 4 days after rock climbing at an indoor gym. On physical examination, he exhibited numbness over the fingers, significant tenderness to palpation, and pain with passive range of motion. His inflammatory markers were markedly elevated and deep space hand infection was confirmed with computed tomography scans. The patient was taken for urgent exploration, irrigation and debridement, and carpal tunnel release. Conclusion/UNASSIGNED:We theorize that the patient had an abrasion on the finger or palm that created an entryway for a pathogen. We are unaware of another report of a deep space hand infection associated with rock climbing activities. This case report will hopefully spread awareness of this clinical entity to improve evaluation and prevention of hand infections in rock climbers, as well as providing guidelines for appropriate and timely treatment of the condition.

3D printing is an evolving technology which has a potential application in the treatment pediatric forearm fractures. Very little has been published with regard to 3D casting in children. We present two cases in which upper extremity fractures in pediatric patients were treated by wearing a custom made 3D printed cast. At latest follow-up at least one year post-injury, the clinical outcomes were excellent. Orthopaedic surgeons may benefit from familiarizing themselves with the potential of 3D printing technology and utilizing its current applications, as well as devising future applications, in clinical practice.

PURPOSE/OBJECTIVE:Surgical site infection (SSI) can be a challenging complication after hand surgery. Retrospective studies often rely on chart review to determine presence of an SSI. The purpose of this study was to assess reliability of Centers for Disease Control and Prevention (CDC) criteria for determining an SSI as applied to a chart review. We hypothesized that interobserver and intraobserver reliability for determining an SSI using these criteria while reviewing medical record documentation would be none to minimal (κ < 0.39) based on an interpretation of Cohen's κ statistics. METHODS:We created and used a database of 782 patients, 48 of whom received antibiotics within 3 months of a surgical procedure of the hand. Three fellowship-trained orthopedic hand surgeons then evaluated the charts of those 48 patients, in which each reviewer determined whether an SSI was present or absent based on CDC criteria provided to the reviewers. Patients' charts were then reassessed 1 month later by the same reviewers. Kappa statistics were calculated for each round of assessment and averaged to determine intraobserver and interobserver reliability. RESULTS:Overall κ values were 0.22 (standard error, 0.13), indicating fair reliability. Average κ value between reviewers was 0.26 (standard error, 0.13. On average, intrarater reliability was 68.7%. CONCLUSIONS:We found poor interobserver and intraobserver reliability when using CDC criteria to determine whether a patient had an SSI, based on chart review. CLINICAL RELEVANCE/CONCLUSIONS:Better criteria or documentation may be needed in patients with an infection after hand surgery. Retrospective chart reviews to assess infection may be unreliable.

PURPOSE/OBJECTIVE:This study aimed to determine the functional characteristics of various arthrodesis angles of the proximal interphalangeal (PIP) joints of the border fingers. METHODS:The dominant hands of 48 volunteers were tested using custom orthoses to simulate PIP joint arthrodesis. For the index finger (IF), orthoses were made in 25°, 40°, and 55° of flexion (IF25, IF40, and IF55). For the little finger (LF), orthoses were made in 30°, 55°, and 70° of flexion (LF30, LF55, and LF70). Twenty-three volunteers performed grip and pinch (key, tripod, and pulp) strength testing with and without simulated arthrodeses and 25 volunteers performed the Jebsen Hand Function Test (JHFT) with and without simulated arthrodeses. Simulated conditions of arthrodesis were compared with the unrestricted state and with each other within the same finger. RESULTS:For grip and pinch strength, there were no significant differences between simulated arthrodesis angles. Compared with baseline, grip was significantly weaker for all 6 simulated arthrodesis angles. Pinch was tested with simulated IF arthrodesis only; key pinch was significantly weaker for all tested angles and tripod pinch for IF25 and IF40. For JHFT, the 3 experimental angles for the index or ring finger did not show any statistically significant differences for any subtest. Volunteers were slower at completion times for all simulated arthrodesis angles compared to baseline times. This was significant in 5 of 7 tasks for IF25, 3 of 7 tasks for IF40, and 4 of 7 tasks for IF55. Index finger angle of flexion of 40° was significantly faster than IF55 for writing and IF25 for lifting large, light objects. For the LF, LF30 was significantly slower than baseline for 6 of 7 tasks, LF55 for 3 of 7 tasks, and LF70 for 5 of 7 tasks. Index finger angle of flexion of 55° was significantly faster than LF70 for simulated feeding and IF30 for lifting large, heavy objects. CONCLUSIONS:No border digit PIP joint arthrodesis angle was superior for grip and pinch strength. Based on JHFT, IF40 and LF55 might be preferred arthrodesis angles. CLINICAL RELEVANCE/CONCLUSIONS:Intermediate arthrodesis angles may provide the best function for patients undergoing PIP joint arthrodesis of the IF and LF.
