[Palmar dislocation of the metacarpophalangeal joint of the thumb. Apropos of a case initially treated by bilateral ligament suture with tendon reinforcement surgery]. / La dislocation palmaire de la métacarpo-phalangienne du pouce. A propos d'un cas traité d'emblée par suture ligamentaire bilatérale avec plastie tendineuse d'appui.

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.

[Dieterich's disease or Kohler III disease or aseptic necrosis of the metacarpal head]. / La maladie de Dieterich ou Kohler III ou nécrose aseptique des têtes métacarpiennes.

This article presents a rare disease, aseptic necrosis of the metacarpal head. The study of the literature on the subject and the author's cases reveal that there is no certain etiology. Some cases have a history of trauma but others are spontaneous. A therapeutic attitude is suggested, although not forgetting the rarity of the disease.

[Injuries of 2 flexor tendons of Verdan's zone II. Multicenter Swiss study]. / Plaies des deux fléchisseurs en zone deux de Verdan. Etude multicentrique suisse.

We report on the results of a swiss multicentric retrospective study collecting 79 complete lesions of both FDP and FDS in zone II and reflecting some variations as well as common habits between the 7 centers when dealing with such settings. After primary repair, striking differences in averaged TAM and TPM motions were observed within the country; some imbalance as nevertheless achieved after tenolysis and other procedures. These proved to be necessary in a relatively high percentage of cases (33%). Thus, it appears that tenorrhaphy still remains a challenging surgical problem.
