Short term comparison of surgery treatment with pin and screw tools in patients with acromioclavicular joint dislocation

Background: The acromioclavicular joint dislocation is one of the most common joint injuries that despite different methods of repair in cases of dislocation of grade 3 to 6, there are still many conflicts regarding the efficacy of these methods in previous studies. Therefore, in this study, we aimed to evaluate the patients' recovery and function after the fixation of the acromioclavicular joint with grade 3-6 using two surgical methods including pin and screw tools.

Methods: In this cross-sectional study, 34 patients with dislocation of acromioclavicular joint with grade 3 to 6 who were treated with pin (group 1) or screw (group 2) in two groups of 17 patients were studied. Satisfaction from surgery and functional recovery were assessed using the Shoulder score questionnaire.

Results: Overall satisfaction rate was 88.2% in the group 1 and 82.4% in the group 2 (P>0.05). There was no significant difference in the range of motion in different motions of the joint (p>0.05). The score for the shoulder score questionnaire was 11.23 in the first group and 11.70 in the second group was, which did not show significant difference (P>0.05).

Conclusion: Surgical treatment using pin and screw tools in cases of acromioclavicular joint dislocation with grade 3-6 can achieve the same therapeutic and functional results. However, more studies are needed to confirm the efficacy of these two tools in various cases of acromioclavicular joint dislocation.
