[Surgical management of acromioclavicular joint separation with transcutaneous Kirschner wire fixation.  Results of follow-up in 45 patients]. 
45 patients were followed up who had undergone surgery because of acromioclavicular separation of the types TOSSY II and TOSSY III during 1983 to 1985.  In 44 cases a fresh acromioclavicular separation had been treated via transcutaneous Kirschner wire fixation and in one case a chronic acromioclavicular separation had been treated according to the technique described by Bunnell.  the anatomy of the acromioclavicular joint, the pattern of injury as well as the method of surgery with subsequent aftercare measures are described.  The good functional final results make transcutaneous Kirschner wire fixation the method of choice as a brief and low-stress procedure, as far as our clinic is concerned.
