[Results of rotation osteotomy using the Weber method in the treatment of habitual shoulder dislocation]

Weber's rotational osteotomy is a surgical treatment of recurrent shoulder dislocation. While eliminating recurrence of the complaint, it attempts to regain full range of movement in the joint. Of the 39 operated patients it was possible to follow up 34 cases. The percentage of recurrent dislocation was 5.7%. The range of movement was reduced in some patients; in one by 10 degrees - 20 degrees. Otherwise there were no significant complications or post-operative complaints. The operative technique, the X-ray procedure and the pathogenesis of the original dislocation are described. Typical accompanying injuries require a particular operative method. The most common accompanying damage was normally the typical defect of the humeral head (incidence 91%). The regular overstretching of the subscapular muscle and the defect of the humeral head are considered by the operational technique introduced by Weber.
