Abstract
Abduction and external rotation of the shoulder are often limited in birth palsy. The most consistent deformities of the shoulder are contracture of internal rotation and abduction, we have performed rotational osteotomy of the humerus on seventeen-year-old male with internal rotational contracture of the shoulder. A limitation of external rotation made it impossible for the hand to reach the mouth without awkward abduction and flexion of the shoulder. The follow-up period is 5 months. Bugler position almost disappeared after surgery. He gained good abduction, of 180 degrees and 10 degrees of external rotation. Function of the arm, the hand have been improved.
