Abstract

PURPOSE
To analyze results of treating acromioclavicular injuries using clavicle hook plates.
MATERIALS AND METHODS
Between February 2008 and April 2010, 18 patients with acromioclavicular joint injury treated by clavicle hook plates were reviewed. Using the Rockwood classification, 7 dislocations were classified as type III injuries and 11 as type V injuries. Implant removal was done at least 3 months from initial fixation. Simple X-rays were taken for comparing the state of reduction, and clinical outcomes were evaluated by the Korean Shoulder Scoring System and the American Shoulder Elbow Society score. The average follow-up period was 9 months.
RESULTS
On weight bearing X-rays, the average coracoclavicular distance showed a 114% increase compared to the contralateral side at the time of injury. It decreased to 23% by the last follow-up. The mean Korean Shoulder Scoring System and the American Shoulder Elbow Society score were 80 and 74 at the last follow-up.
CONCLUSION
The immediate stability these plates provide allows rapid rehabilitation. Clavicle hook plate fixation for acromioclavicular joint dislocation is considered an effective method for ensuring satisfactory results both radiologically and clinically.
