[Subcutaneous rupture of the extensor tendon of the fingers and its treatment].

The process used in 47 cases for treatment of subcutaneous rupture of the extensor tendon at the level of the third phalanx is described. This process of mixed type consists in making a temporary fixation of the third phalanx in slight extension on the second by means of the endomedullary infibulum, to which is added a plaster guardian with 60 degrees flexion of the interphalangeal for six weeks. After illustration of the method, a full set of cases is presented in demonstration of the perfect efficiency of the method through the good results obtained.
