[Reconstruction of the trapeziometacarpal joint and the first metacarpal bone by reversed free osteocutaneous dorsalis pedis flap].

A case of reconstruction after first metacarpal resection by reversed free vascularized osteocutaneous pedis flap is presented. This procedure avoids bone resorption and preserves the trapezio metacarpal joint contrary to conventional bone graft. A double rotation is applied to the flap: the head of the metatarsal becomes proximal and the palmar side becomes dorsal. The metacarpo-phalangeal joint undergo arthrodesis. With a follow up of three years, there is no pain, the Kapandji score is 8/10 (very good range of motion), there is no osteoarthritis.
