Abstract:[Objective] To compare the clinical outcomes of arthroscopic suspension fixation around coracoid versus clavicular hook plate fixation for acromioclavicular dislocation. [Methods] A retrospective study was done on 55 patients who received surgical treatment for acute closed acromioclavicular dislocation in our hospitals from January 2018 to June 2021. According to the results of doctor-patient communication, 21 patients received arthroscopic suspension fixation around the coracoid (ASFC), while the other 34 patients underwent clavicular hook plate (CHP). The clinical and imaging documents were compared between the two groups. [Results] All the patients had op- eration performed successfully in both groups. The ASFC group proved significantly superior to the CHP group in terms of intraoperative blood loss [(9.8±4.9) ml vs (35.9±11.3) ml, P＜0.05] and incision length [(4.1±0.6) cm vs (7.2±1.3) cm, P＜0.05], although the former con- sumed significantly longer operation time than the latter [(89.1±18.7) min vs (61.7±12.5) min, P＜0.05]. The VAS score for pain decreased significantly (P＜0.05), while the ASES and Constant-Murley scores increased significantly over time in both groups (P＜0.05). The ASFC group was significantly better than the CHP group in terms of VAS score [(1.1±0.7) vs (1.8±0.9), P＜0.05], ASES score [(91.2±3.1) vs (80.1± 4.8), P＜0.05] and Constant-Murley score [(90.7±5.5) vs (80.2±7.4), P＜0.05] 6 months postoperatively. Radiographically, the acromioclavic- ular distance (ACD) and coracoclavicular distance (CCD) significantly decreased 6 months after surgery compared with those preoperatively in both groups (P＜0.05), which proved not statistically significant between the two groups at any time points accordingly (P＞0.05). [Conclu- sion] Compared with clavicular hook plate, the arthroscopic suspension fixation around coracoid for acromioclavicular dislocation reduces postoperative shoulder pain, and is more beneficial to the functional recovery of the shoulder.
