[Anatomy of the sulcus of the extensor carpi radialis tendon (author's transl)].

The anatomy of the sulcus of the extensor carpi radialis tendon was analyzed in order to establish the importance of anatomic variation of the bony bed for the development of habitual dislocation of the tendon. Length, width and slope of the lateral walls were measured. Additional morphologic description permitted to distinguish 4 different types of sulcus. The results mean that the anatomy of the sulcus has only an indirect connection with dislocation, via laxity of the retinacula.
