Abstract: Objective To compare the short-term curative effects of clavicular hook plate placement and coracoclavicular ligament reconstruction on acromioclavicular joint dislocation. Methods The clinical data of 200 patients with acromioclavicular joint dislocation who were treated with clavicular hook plate placement and coracoclavicular ligament reconstruction in Beijing Tongren Hospital and Beijing Jishuitan Hospital Affiliated to Capital Medical University from August 2016 to August 2018 were retrospectively analyzed. According to the treatment method, they were divided into group A (clavicular hook plate placement, n=108) and group B (coracoclavicular ligament reconstruction, n=92). The operation conditions and hospitalization time of the two groups were compared. The follow-up lasted for 6 months after surgery. The range of motion, score of visual analogue scale (VAS), score of Constant-Murley shoulder joint function and excellent rate of Karlsson grading were compared between the two groups. Results The operation time of group B was significantly longer than that of group A, while intraoperative blood loss was significantly less than that of group A. The hospitalization time was significantly shorter than that of group A (P<0.05). The follow-up last for 6 months. The range of motion of group B was significantly greater than that of group A. The VAS score was significantly lower than that of group A. The prognosis was significantly better than that of group A (P<0.05). The difference in Constant-Murley score and excellent rate of Karlsson grading between the two groups was not statistically significant (P>0.05). Conclusion The surgical injury of coracoclavicular ligament reconstruction is less for patients with acromioclavicular joint dislocation, and the recovery of shoulder joint function and prognosis are better. It is an effective and safe method for the treatment of acromioclavicular joint dislocation with high clinical value.
