Clinical study on treatment of TOSSY type III acromioclavicular joint dislocation with clavicular hook plate combined with coracoclavicular ligament repair

Abstract

Objective: To explore the treatment of TOSSY type III acromioclavicular joint dislocation with clavicular hook plate combined with coracoclavicular ligament repair and its clinical effect.

Methods: 80 patients with TOSSY type III acromioclavicular joint dislocation who were admitted to our hospital from January 2014 to January 2019 were selected. They were randomly divided into the control group (n = 39, treated with clavicular hook plate) and the observation group (n = 41, treated with clavicular hook plate combined with coracoclavicular ligament repair) by the random number table method. The clinical efficacy in 12 months after operation, related clinical indicators, 12-month postoperative recovery and postoperative complications were compared between the two groups.

Results: The excellent and good rate was 92.68% (38/41) in 12 months after operation in the observation group, which was higher than that (76.92%, 30/39) in the control group (p < .05). There were no significant differences in the duration of surgery, intraoperative blood loss and HLOS between the observation group and the control group (p > .05). In 12 months after operation, abduction activity and forward flexion activity of the observation group were higher than those of the control group, and visual analogue score (VAS) was lower than that of the control group (p < .05). The incidence of complications in the observation group was slightly lower than that in the control group, but there was no statistically significant difference between the two groups (p > .05).

Conclusions: For TOSSY type III acromioclavicular joint dislocation, clavicular hook plate combined with coracoclavicular ligament repair has a good clinical efficacy. It can improve shoulder joint function, alleviate shoulder pain and have fewer complications. It can provide a reference for clinical treatment of this type of acromioclavicular joint dislocation.
