[Fenton's syndrome or scapho-capitate fracture (a case report)].

INTRODUCTION

Scapho-capitate fracture is a rare lesion and its mechanism is controversial. Forced extension seems to be the most frequent cause as this movement of the wrist induces scaphoid fracture by compression. Hyperextension of the wrist as a result of the scaphoid lesion, allows contact between the posterior margin of the radius and the neck of the capitate inducing a capitate fracture.

MATERIALS AND

METHODS

We report a case of Fenton's Syndrome, the patient was operated as an emergency by pining and immobilization of the carpus and thumb until bone consolidation had occurred.

RESULTS

Consolidation was noted at 8 weeks with a good mobility of the wrist.

DISCUSSION: Fenton's Syndrome is a rare lesion of the wrist. Analysis of our own case and a review of literature demonstrated extension as a causative mechanism, and the frequency of delayed diagnosis. Because of the presence of instability, scaphoid reduction and osteosynthesis is necessary. Immobilization of the carpus and thumb is essential until bony consolidation is obtained.
