[Bifocal fracture of sternal end of clavicle-pseudodislocation of sternoclavicular joint. Report of a case].

We report an unusual case of bifocal fracture of the sternal part of clavicle, combining a metaphysodiaphysal fracture of the sternal end of the clavicle, a proximal physeal fracture, and a ligament avulsion of sternoclavicular joint, without neurovascular damage. Its surgical repair used an osteosynthesis with K-wires and tension band wiring and synthetic ligamentoplasty of the anterior and posterior sternoclavicular ligaments, without any reconstruction of the costoclavicular ligament. The clinical and radiographic results at six months are presented and the operative technique used in this case of pseudodislocation of sternoclavicular joint is discussed and compared to those previously published.
