[Functional treatment of fractures of the mandibular condyle and its neck].

The functional treatment of condylar and sub-condylar fractures requires very early mobilisation of the mandible, in protraction. This form of treatment, suggested in France since 1928 by L. Lebourg, is usually carried out with the aid of traction using a plaster helmet. The authors use more simple inter-maxillary traction (as parallel as possible from the standpoint of occlusion) followed by propulsion plates.
