Background: A single-site retrospective study was designed to evaluate the clinical outcomes of single-screw lunocapitate arthrodesis (LCA) using a retrograde approach for the treatment of scapholunate advanced collapse (SLAC) wrist., Methods: We retrospectively identified 31 patients (33 cases) between September 2010 and December 2019 with SLAC wrist changes who were treated with single-screw LCA. Objective outcomes included time to fusion, union rate, range of motion, and grip and pinch strength recovery. Subjective outcomes included Disabilities of the Arm, Shoulder, and Hand (DASH) scores., Results: We report on 33 cases (7 female), mean age 58.4 years (range: 41-85), with SLAC wrist who underwent LCA. Our cohort reported a 94% union rate and a 90-day mean time to fusion. Final active wrist range of motion was 38° dorsiflexion, 35° volarflexion, 17° radial deviation, 17° ulnar deviation, 82° pronation, and 83° supination (mean: 450.8 days). Final grip and pinch strengths recovered was 75% gross grip, 84% lateral pinch, and 75% precision pinch (mean: 379.0 days) compared with the contralateral side. The mean postoperative DASH score was 27 (mean: 1203.9 days). Two nonunions were observed. Two hardware complications occurred: one symptomatic screw and one screw fatigue fracture., Conclusions: We found retrograde single-screw LCA to be an effective salvage procedure for SLAC wrist. LCA is a less-taxing procedure, requires shorter operating time, and produces range of motion and grip and pinch strength recovery comparable to those of 4-corner arthrodesis. Furthermore, the viability of single-screw fixation may reduce hardware-related operative costs without compromising union rates., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: This study aimed to examine the relationship between anatomical surface landmarks in fresh frozen cadavers as related to in vivo endoscopic trigger finger release (ETFR) and present clinical outcomes after a single-portal antegrade ETFR technique., Methods: Endoscopic trigger finger release was performed on 40 cadaveric digits. Each digit was dissected and the following measurements were recorded: distance from palmar digital crease and A1 pulley, length of the A1 pulley, percentage of A1 pulley released, and injury to vulnerable anatomy. A retrospective chart review was performed on 48 patients (62 digits) treated with ETFR. Outcome measures included grip and pinch strength, range of motion, Disability of Arm, Shoulder, and Hand (DASH) questionnaires, and Visual Analog Scale (VAS) pain scores., Results: Release of the A1 pulley was achieved in 33 of the 40 cadaveric digits (83%) with an A2 pulley laceration rate of 25%. No flexor tendon or neurovascular injuries occurred. Gross grasp, lateral pinch, 3-jaw chuck, and precision pinch strength had 85%, 90%, 82%, and 90% recovery, respectively. At the final follow-up, average metacarpophalangeal joint, proximal interphalangeal joint, and distal interphalangeal joint range of motion were within the normal limits. Mean VAS scores decreased from 5.7 preoperatively to 1.0 postoperatively and mean DASH score at the final follow-up was 4.8., Conclusions: With the use of anatomical surface landmarks, ETFR may be performed in an efficient and reproducible manner. Patients treated with ETFR had low complication rates, good functional recovery, and improved pain at short-term follow-up. Further study of long-term outcomes and cost-effectiveness of ETFR is warranted., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: A.M. receives IP royalties, financial or material support, and stock or stock options from A.M.

Background: Open trigger finger release (OTFR) and endoscopic trigger finger release (ETFR) are effective methods in treating stenosing tenosynovitis. However, a paucity of literature exists comparing the techniques. This study describes and compares postoperative complications following OTFR and ETFR at a single institution., Methods: Patients undergoing trigger finger release between 2018 and 2020 within a single institution were identified. Electronic medical records were reviewed for patient demographics, surgical history, surgical characteristics, and clinical outcomes. Major and minor postoperative complications were assessed. Secondary outcome measures included tourniquet time and procedure time. Statistical analysis evaluated associations between postoperative complications, surgical technique, patient demographics, and surgical characteristics., Results: In total, 57 patients (80 digits) were included in the study: 42 digits treated with OTFR and 38 digits treated with ETFR. Mean follow-up time was 57.6 ± 69.0 days (range, 7-307 days) for ETFR and 34.2 ± 26.3 days (range, 6-120 days) for OTFR. Overall, major, and minor complication rates for the cohort were 8.8%, 1.8% and 7.0%, respectively. There were no major complications following ETFR and 1 following OTFR (4%), the isolated case being postoperative Chronic regional pain syndrome. Minor complication rates were similar following OTFR (8%) and ETFR (6%). Persistent digit stiffness and swelling were found to be the most prevalent minor complications (n = 2, respectively), followed by wound dehiscence (n = 1). Female patients were significantly more likely to experience postoperative complications., Conclusions: Major complications following trigger finger release are unlikely; however, minor complications are prominent. Patients treated with OTFR and ETFR showed similar postoperative complication rates. Continued investigations into the benefits of ETFR are warranted., Competing Interests: Ethical ApprovalOwing to the retrospective nature of the deidentified chart review, this study was not submitted for institutional review board review.

Background: To present a retrospective study on the outcomes of a modified version of suture suspension arthroplasty with trapeziectomy on patients with thumb basal joint arthritis and to evaluate the relationship between the degree of subsidence and functional outcome. Methods: We performed a chart review on 67 patients (75 thumbs) who were surgically treated for thumb carpometacarpal osteoarthritis with trapeziectomy and suture suspension arthroplasty from May 2010 to May 2016. Outcome measures included Disabilities of the Arm, Shoulder and Hand (DASH), grip strength, lateral/precision pinch strength, range of motion, and return to work/resumption of usual activities. Radiographic images were used to measure first metacarpal subsidence into the trapezial space. Results: Clinical outcomes were satisfactory, showing an initial postoperative DASH score of 45.94, which decreased to 27.93 at 6 months postoperatively and to 19.69 at 1 year postoperatively. Radiographic images revealed a mean first metacarpal subsidence of 39% compared with the preoperative images. Grip and pinch strengths showed steady improvement from initial postoperative to final follow-up visits, resulting in 90% recovery of gross grasp, 77% recovery of lateral pinch, and 79% recovery of precision pinch compared with the contralateral side. Conclusions: Our study has found that suture suspension arthroplasty with trapeziectomy is an effective treatment for thumb basal joint arthritis. Suture suspension arthroplasty allows for short immobilization time, avoids tendon sacrifice, avoids anchor use, and leaves a cosmetically appealing scar. Furthermore, a relationship of any significance between postoperative first metacarpal subsidence and functional outcomes does not appear.

Background: The purpose of the article was to evaluate clinical and radiographic outcomes in a case series of unstable metacarpal fractures treated with flexible intramedullary nail (IMN) fixation., Methods: A total of 55 patients with unstable metacarpal fractures between 2003 and 2010 were treated with IMN fixation and followed for a minimum of 1 year. The outcomes were assessed via a radiological study of longitudinal and angular collapse, Disabilities of the Arm, Shoulder, and Hand (DASH) score, total active range of motion (ROM) of the wrist, and grip strength testing., Results: In the 55 patients, metacarpal fractures were healed by clinical and radiographic assessment at an average of 12.7 weeks. IMNs were removed in all cases at an average of 13.9 weeks. Patients regained full finger ROM at the final follow-up and were capable of 72.4% of motion at 2 weeks postoperatively. The mean DASH score at the final follow-up was 6.5. Complications included 3 cases of extensor tendon irritation that resolved without functional impairment and 2 cases of "backing out" that required reoperation to replace the pin. In one case, a bony exostosis formed on the affected metacarpal that led to tendon irritation and required operative excision., Conclusions: We found that this technique allowed for the stabilization of fractures, early ROM, resumption of usual activities, reduced immobilization, and minimal complications. A removable orthosis, instead of a cast, allowed for earlier mobilization of the wrist, metacarpophalangeal, and proximal interphalangeal joints.
