We describe a new procedure of trapeziometacarpal ligamentoplasty. This ligamentoplasty is both passive and active. The operation is performed in three stages: (1) Transfert of part of the abductor pollicis longus in a posterior and distal direction; (2) Transfert of the radial part of the extensor carpi radialis longus into the proximal first metacarpal; (3) Forming a loop around the flexor carpi radialis tendon with a distally inserted slip of abductor pollicis longus.
