Nouvelle ostéotomie métacarpienne: l'ostéotomie cervico-capitale d'accourcissement métacarpien dans la main rhumatismale

Abstract

Volar dislocation of the four long fingers is a common situation in rheumatoid hands. Surgical reduction is rather difficult because of soft tissue retraction, especially interosseous muscles, and requires large releases. The authors propose the use of Weil's osteotomy, initially described in foot surgery. This is an oblique cervico-capital osteotomy which shortens the metacarpal bone, fixed by two screws. This makes soft tissue release less extensive and facilitates relocation of the extensor tendon. Two cases are reported.
