Luxation traumatique de l'appareil extenseur au dos de l'articulation métacarpophalangienne. À propos d'un cas et revue de la littérature

The authors report the case of a dislocation of the extensor tendon over the metacarpophalangeal joint of the long finger, resulting from posttraumatic rupture of the radial sagittal band. A surgical procedure was performed to improve functional rehabilitation. The outcome at six months was excellent and the patient returned to sports, without recurrence of extensor tendon instability.
