There has been more controversy concerning the acromioclavicular joint regarding treatment for injuries and complications than that for any other joint of its size in the boey. The aims of the treatment ofthe acromioclavicular dislocation were
regain of
function and prvention of the deformjty 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, and infections. Therefore, open reduction was avoided in spite of surgical indication occasionally. So considering these problems, we have treated 26 cases
of
acute acromioclavicular dislocation with percutancous K-wire pinning from March 1987 to January 1991. The 17 cases were followed up over 6 months after sugery.
@ES The results were as follows:
@EN 1. There were 4 cases of Type II (23%). l? cases of Type III (65%). 1 case of Type IV (6%), 1 case of Type V (5.9%). based on the Rockwood's 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%0 were be?veen 1 and 2 weeks. w cases (12%) were over 2 weeks.
4. The results were good in 10 cases (59%). fair in 3 cases (18%) and poor in 4 eases (23%)
5. causes of poor results were old age, incomplete reducton incomplete stable fixation. and delayed operation.
6. There were conplicatons such as 4 cases of busitis. 2 cases of skin ulceration. 1 cases of migration of K-wires. and 4 cases of redislocation.
