Presentation Description

Institution: Royal Brisbane and Womens Hospital - QLD, Australia

Background: Traumatic dislocation of the first carpometacarpal joint (CMCJ) is rare, with significant implications for hand function. Grip and pinch strength can be permanently impacted if not properly managed. No consensus exists on surgical management due to limited literature. Method:A PubMed database search from 1995 to 2025 using terms (first carpometacarpal dislocation) OR (thumb carpometacarpal dislocation) AND (traumatic) and (reconstruction) identified 20 articles. 7 studies meeting inclusion criteria were selected, focusing on surgical management of isolated, traumatic thumb CMCJ dislocation in adults. Results:The analysis included 3 retrospective studies and 4 case reports, with a sample size of 44. 34 patients underwent ligamentous repair, with the technique varing between studies 1 patient had reconstruction with a suture anchor, while 9 patients underwent closed reduction and percutaneous Kirschner wire fixation. 44% of patients managed with closed reduction and percutaneous fixation required revision surgery due to recurrent instability or degenerative osteoarthritis. Conclusion: Current literature demonstrates significant variability in surgical approaches for traumatic first carpometacarpal joint dislocations. Prospective, large-scale studies are essential to develop standardized treatment guidelines that can consistently restore hand structure and function.
