[Palmar dislocation of the metacarpophalangeal joint of the thumb. Apropos of a case initially treated by bilateral ligament suture with tendon reinforcement surgery].
We report a case of complete palmar dislocation of the metacarpophalangeal joint of the thumb with simultaneous rupture of the radial and ulnar collateral ligaments. This highly unstable condition needs a reliable augmentation ligamentoplasty which was achieved with a free palmaris longus tendon graft. This type of transosseous plasty reinforces the collateral ligaments at their anatomical sites. The 7 month end-results is promising: the metacarpophalangeal joint remains perfectly stable and painless in spite of a slight residual stiffness which causes no discomfort to the patient.
