Tratamiento quirúrgico de fracturas tipo A3 de húmero proximal

32 cases of A3 type fracture of the proximal humerus are presented. They were treated surgically by reduction and internal fixation with a proximal humeral nail or a locking plate. The results were satisfactory at most of the patients concerning the residual pain (mean Constant-Murley pain score: 11,88/15), the strength (mean Cons- tant-Murley strength score: 15,13/25) and joint mobility of the shoulder (mean Constant-Murley mobility score: 20,88/40). The most important complications were rotator cuff disorders (34,4%), varus consolidation of fracture (31,3%) and prominent hardware to the joint (12,5%). A3 type fractures of the proximal humerus are injuries that evolve normally well, when the surgical technique is performed correctly.
