Comparison of two methods of acute dislocation fiation of acromioclavicular oint with hook plate and screw

Abstract

Acromioclaviculer joint dislocation is one of the most common shoulder injuries, especially in young and athletes, which has a significant effect on patient's function. Therapeutic strategies include non-surgical methods and a variety of surgical methods. Each of the two therapies has some advantages and disadvantages and careful decision making regarding the appropriate therapeutic approach in these patients has not been achieved due to controversial results. Standard surgical treatment is not specified. In this regard the present study was conducted to compare bothrow scale and hook plate. Methods: In this retrospective cohort study, 68 patients were referred to the Tabriz Shohada Medical Education Center in 2014 to 2017 with the dislocation of the 4th, 5th and 6th grade acromyoclavicular joint dislocation. The patients were enrolled in the study, and in this study, 44 patients open reduction and internal fixation with screw and 24 patients underwent ORIF with Hook plate. The retest workers, shoulder range, pain and device failure were compared between the two groups. Results: According to the results, there were no significant differences between 68 patients with acute dislocation of ACJ type 4, 5 and 6 in return to work time and also pain intensity in the two groups (P =0.78 and P =0.29), but in the examinations ROM limits for abduction, forward flexion and external rotation were significantly higher in Hook plate than the screw (P =0.03, P =0.001 and P =0.02, respectively). The maximum motion limitation was in shoulder abduction, but the internal rotation between the two groups was not significantly different. Also, the device failure rate for the screw was significantly higher and was approximately 18.4%, whereas in the hook plate fixed with no plate device failure failed.
