[Postoperative complications of acromioclavicular joint dislocation of Tossy III].
OBJECTIVE
To analyze retrospectively the postoperative complications of acromioclavicular joint dislocation (Tossy III) and explore the preventative methods for the complications.


METHODS
Forty-eight cases of acromioclavicular joint dislocation (Tossy III) were reviewed, 14 cases treated with open reduction and Kirschner wire combined with steel wire fixation (group A), 11 cases treated with open reduction and lag screw or steel wires fixation (group B), 23 cases treated with open reduction and AO clavicular hook plate fixation (group C). The acromioclavicular ligament, articular capsule, coracoclavicular ligament and coracoacromial ligament were repaired in all patients. The reasons of postoperative complications were analyzed.


RESULTS
Forty-eight patients got average follow-up of 18 months. In group A, 8 patients obtained excellent results, 4 good and 2 poor; in group B, 7, 3 and 1, respectively; in group C, 21, 1 and 1, respectively. The excellence rate showed statistical difference between group A and C (P < 0.05). In group A, 4 cases with postoperative pain, 3 cases with periarthritis of shoulder, 3 cases with arthritides of acromioclavicular joint, 4 cases with internal fixation failure and 2 cases with recurrence of joint dislocation; in group B, 3, 2, 1, 3 and 1, respectively; in group C, 22, 2, 1, 2 and 1, respectively. There was no significant difference in postoperative complications in three groups (P > 0.05).


CONCLUSIONS
Selection of the suitable internal fixation and reconstruction of coracoclavicular and coracoacromia ligaments is the basic operation. Acromioclavicular space debridement, ligamentous reconstruction, rigid internal fixation are effective methods to reduce postoperative complications for the treatment of acromioclavicular joint dislocation.
