Multiple Carpo-Metacarpal Joint Dislocations: A Case Series

Abstract

Introduction: Dislocations of the carpometacarpal (CMC) joint, particularly those affecting multiple joints, are exceptionally uncommon and frequently misdiagnosed owing to minor clinical and radiological indicators.

Methods: We present two cases of volar dislocation affecting the CMC joints. The initial case pertained to an elderly male who incurred a right-hand injury after a fall from a two-wheeler, leading to volar subluxation of the first, second, and third carpometacarpal joints, accompanied by a comminuted fracture of the trapezium. The second case related to a youngster who sustained a left-hand injury from an assault, resulting in volar dislocation of the second and third carpometacarpal joints. Both patients underwent effective treatment using closed reduction and internal fixation with Kirschner wires, subsequently followed by immobilization and rehabilitation.

Result: At the one-year follow-up, both individuals achieved complete functional recovery with sufficient grip and pinch strength.

Conclusion: These cases underscore the significance of comprehensive clinical assessment and suitable imaging in the diagnosis of CMC dislocations. Timely surgical intervention utilizing K-wire fixation is a straightforward yet efficacious method for attaining superior results in these rare accidents.
