[A minimal trapezometacarpal ligamentoplasty].
To correct chronic instability of the trapeziometacarpal joint, the authors reconstructs the posteromedial ligamentous complex using flaps of extensor retinaculum. Two small dorsal incisions allow harvesting free segments of extensor retinaculum detached from the proximal portion of extensor retinaculum to repair dorsal injuries when these prove to be superficial. When necessary, a clip passed via a small palmar cunter incision allows a complementary palmar reconstruction. For repair of anterior ligaments, the palmar incision can be extended and a pedicled flap derived from the retinaculum is used. There is a detailed description of technique and results.
