Background
The purpose of this study was to research the effect of different hook depths on the efficacy and complications of AC dislocation treatment with hook plate, and to provide valuable reference for clinical treatment.
Method
We retrospectively analyzed the prospectively collected data from 305 consecutive patients with AC joint dislocation between April 2013 and May 2017 at our institute. We defined〝hook tip depth〞as the position of the hook tip relative to the acromion at the coronal plane. According to the division where the tip of the hook was located, the cases were divided into Group A, Group B, Group C, and D group. All patients were required to conform to regular follow up postoperatively. Dislocation and implant maintenance are assessed by routine shoulder imaging. Functional results were evaluated using Constant-Murley criteria.
Results
A total of 305 cases were included in follow-up and 27 cases were lost. We used Constant-Murley criteria to evaluate functional results. The score of Group B was significantly higher than group A and group C (P<0.01). For evaluation of acromioclavicular joint reduction, we used CCD in imaging to evaluate. There was significant difference between the three groups. Joint reduction was obtained in all patients. Postoperative infection and hardware failure did not present. There were no fractures of acromion and coracoids process. There were 83 cases of shoulder pain, 93 cases of SIS and 124 cases of subacromial erosion. The incidence of complications in group A was significantly higher than group B and group C.
Conclusions
The relative position of the hook tip and acromion can significantly affect the efficacy and complications of the clavicular hook plate in the treatment of acromioclavicular joint dislocation. During surgery, we should control the depth of hook tip and try our best to put the tip of the hook into the area of group B to achieve an ideal postoperative effect and avoid the occurrence of various complications.
