Abstract

• There has been more controversy controversy the acromioclavicular koint regarding treatment for injuries and complications than that iHr any other joint of its size in the body. The aims of the treatment of the acromioclaviclavicular dislocation were regain of function and prvention of the deformity by accurate reduction of the dislocaton At recently. surgical treatment was favored because of many disadvantages of the conservative treatment. However, in the cases of open reduction and internal fixation, there are many complications such as poor cosmetic scar. anxiety of patient to operation. anesthetic complications, and infections. Therefore. open reduction was avoided in spite of surgical indication occasionally. So considrring there problems, we have treated 26 cases of acute acromioclavicular dislocation with percutaneous K-wire pinning from March 1987 to January 1991. The 17 cases were followed up over 6 months after sugery.
  The results were as follows;
  1. There were 4 cases of Type II (23%). 11 cases of Type III(65%), 1 case of Type IV. (6%), 1 case of Type V (5.9%). based on the Rockwoods classification.
  2. Eleven cases (64.7%) were performed with general anesthesia. 6 cases (35. 5%) were performed with local anestheisa.
  3. According to the interval from injury to operation. 13 (76%) cases were below 1 week. 2 cases (12%) were between 1 and 2 weeks, 2 cases (12%) were over 2 wreks.
  4. The results were good in 10 cases (59%), fair in 3 cases (18%) and poor in 4 cases (23%).
  5. causes of poor results were old age. Incomplete reducton, incomplete stable fixation, and delayed operation.
  6. There were complicatons such as 4 cases of bursitis, 2 cases of skin ulceration, 1 case of migration of K-wires, and 4 cases of redislocation.
