Osteosynthesis of fractures of the base of the first metacarpal by an external fixator.

Among the various methods for treating fractures of the base of the first metacarpal, use of the external fixator appears to be of interest for it maintains a satisfactory reduction while respecting the arch of the first web interspace as well as allowing early mobilization of all joints not involved in the injury. The miniaturization of the material, today possible, facilitates its use. The experience with 20 cases gained at the CTO de la CRAM de Strasbourg is presented. The authors discuss the utilization of the method, the practical means of doing it and their results. Its limitations are indicated as well as its special indications in comminuted and compound fractures.
