Abstract:
Objective:To evaluate the early clinical outcomes of modified suspended fixation with triple plates and double beams through a limited incision in the treatment of acroxoclavicular dislocation.Methods:A retrospective study was conducted to analyze the 23 patients with acromioclavicular dislocation who had been treated at Department of Orthopedics, The People's Hospital of Northern Jiangsu from June 2021 to August 2023 by modified suspended fixation with triple plates and double beams through a limited incision. There were 9 males and 14 females with an age of (52.2±10.6) years. The incision length, operation time, intraoperative bleeding and complications were recorded. The visual analogue scale (VAS) pain score, Constant-Murley shoulder score, American Shoulder and Elbow Surgeons (ASES) score, range of shoulder motion (anterior flexion, abduction, lateral rotation) were recorded and compared between preoperation and the last follow-up. The coracoclavicular distance (CCD), clavicle tract width and coracoid tract width were measured and compared between postoperative day 2 and the last follow-up.Results:The patients were followed up for 12 (12, 16) months. The incision length was 5 (4, 5) cm, the operation time 50 (40, 60) min, and the intraoperative bleeding 30 (20, 30) mL. No such complications occurred as incision infection, fracture, or failure of internal fixation. The VAS pain score, Constant-Murley shoulder score, ASES score, anterior flexion, abduction and lateral rotation of the shoulder at the last follow-up were, respectively, 0 (0, 0) point, (92.8±4.9) points, (90.4±5.7) points, 175 °(170°, 180°), 175°(170°, 175°), and 85°(80°, 85°), significantly improved compared with the preoperative values [6 (5, 6) points, (40.4±7.2) points, (39.3±7.1) points, 85°(80°, 85°), 85°(80°, 90°), and 35°(35°, 40°)] ( P<0.05). The CCD was (6.1±1.3) mm at postoperative day 2 and (7.5±1.7) mm at the last follow-up, showing a significant difference ( P<0.05). Compared with postoperative day 2, the CCD widening at the last follow-up was <4mm in all patients, giving an excellent rate of 100% (23/23). The medial clavicle tract widening and the medial coracoid tract widening at the last follow-up were both <2 mm in all patients, giving an excellent rate of 100% (23/23). The lateral clavicle tract widening at the last follow-up was >2 mm in 2 patients, giving an excellent rate of 91% (21/23). Conclusions:In the treatment of acroxoclavicular dislocation, our modified suspended fixation with triple plates and double beams through a limited incision can lead to reliable reduction fixation and good recovery of shoulder function, showing advantages of short surgical time, easy surgical operation, high safety, and minimal postoperative widening of bone tracts.
