Surgical treatment of Trapezo-metacarpal luxation

Introduction: Trapeziometacarpal dislocation, often resulting from violent trauma in young people, is generally diagnosed clinically and by imaging. It can cause instability of the first column and promote the development of rhizarthrosis . The treatment of fresh dislocations gives rise to debates between orthopedic and surgical approaches. This series reports a number of cases rarely exceeding fifteen.

Material and method: This is a retrospective series of five cases of trapezio -metacarpal dislocation collected between January 2017 and October 2022 in the trauma-orthopedics department of Wing 4 of the Ibn Rochd University Hospital in Casablanca.

Results: The patients were mainly men with an average age of 34 years, with lesions mainly located on the right side and caused by road accidents or falls. The diagnosis was confirmed by radiographs, mainly revealing isolated trapeziometacarpal dislocations. Treatment consisted of percutaneous metacarpo - trapezius pinning , with good short-term results for all patients.

Discussion: Trapeziometacarpal dislocation is a rare pathology. Its diagnosis is based on radiological examinations and therapeutic approaches such as trapeziometacarpal pinning.

Conclusion: Treatment by reduction followed by pin stabilization seems to offer satisfactory results for trapeziometacarpal dislocation.
