Clavicular hook plate in treatment of distal clavicle fractures and acromioclavicular joint dislocation

Objective To study the curative effects of clavicular hook plate (CHP) in treatment of the fractures of distal clavicle and dislocation of acromioclavicular joint. Methods From April 1999 to April 2002, 22 cases with distal clavicle fractures or acromioclavicular joint dislocation were treated with CHP. The broken acromioclavicular ligament was repaired directly in all the cases. The outcomes were evaluated. Results All the cases were followed up for 6 to 24 months (averaging 12 moths). All the dislocated acromioclavicular joints returned to normal 2 weeks after operation, and obtained satisfactory motion with 90 degrees of flexion and 90 degrees of abduction on average. CHP was taken away 6 to 12months (averaging 8 months) postoperatively. Excellent plus good rate of shoulder function was 100%according to Karlsson evaluation. Conclusion When degree Ⅲdislocated acromioclavicular joint is treated with CHP, the acromioclavicular joint can exercise earlier and recover quickly. The curative effect of CHP has proved to be satisfactory.
