[Epiphyseal fracture-avulsion of the distal extremity of the clavicle. Apropos of a case].

Fracture of the clavicle is the commonest fracture in children. It is generally due to direct trauma to the shoulder. Orthopaedic usually ensures consolidation within three weeks. Fractures of the lateral third is uncommon and unusual. It corresponds to an epiphyseal avulsion of the distal extremity of the clavicle, equivalent to an acromioclavicular "pseudodislocation". The coracoclavicular ligaments remain intact. Surgical reduction of the clavicle into its periosteal sheath is necessary. The authors report a case of fracture of the lateral third of the clavicle in a 5 and a half year old child with spontaneous formation of a "neoclavicle".
