Measuring secondary deformities of the shoulder in children with obstetric brachial plexus lesion: reliability of three methods.

A rare case of tibial apophyseal fracture with extension in the antero-lateral physis and epiphysis in a 17-year-old boy is described. This type of fracture, which can be associated with intra-articular lesions and lesions of the extensor mechanism, resembles the better known distal tibial triplane fracture. Arthroscopic controlled anatomic reduction with restoration of the articular surface was achieved.
