ABSTRACT
Objective To analyze the effect of clavicular hook plate (CHP) in treating dislocation of the acromioclavicular joint and fractures of the distal clavicle. Methods From July 2000 to May 2001, 12 cases with acromioclavicular joint dislocation or distal clavicle fractures were treated using CHP and its effect evaluated. Results All patients got good reduction and fixation and 2 weeks after operation they obtained satisfactory motion with average 90 degrees of flexion and 90 degrees of abduction. One patient suffered from impingement of the shoulder joint because of unsatisfactory preliminary flexion but the joint function was not affected posterior to extraction of inernal fixation. The X-ray showed good reduction in all patients. No re-fracture or subluxation occurred after removal of implants with 100% of joint function recovery. Conclusions CHP is a reliable way for acromioclavicular joint dislocation and distal clavicle fractures.
