Objective  To investigate the effectiveness of TightRope system combined with Locking-Loop biplane anatomical reconstruction technique in the treatment of acute acromioclavicular joint dislocation. Methods  A clinical data of 28 patients with acute acromioclavicular joint dislocation who met the selection criteria and admitted between June 2018 and December 2021 was retrospectively analyzed. There were 18 males and 10 females, with an average age of 47.7 years (range, 22-72 years). The causes of injury included falling (13 cases) and traffic accidents (15 cases). The acromioclavicular joint dislocation was rated as Rockwood type Ⅲ in 7 cases, type Ⅳ in 16 cases, and type Ⅴ in 5 cases. The time from injury to operation was 4-13 days, with an average of 9.5 days. The acromioclavicular joint dislocation was reconstructed with TightRope system and high-strength wire by Locking-Loop methods during operation. The operation time and complications were recorded. Visual analogue scale (VAS) score, Constant-Murley score, and active range of motion of shoulder (forward flexion and upward lift, abduction and upward lift, and external rotation) were recorded before operation and at 12 months after operation to evaluate the functional recovery of shoulder. The loss of acromioclavicular joint reduction was assessed by comparing the coracoclavicular distance (CCD) based on the anteroposterior X-ray films at 3 days and 12 months after operation. Results  The operation time was 58-100 minutes (median, 85 minutes). All incisions healed by first intention. All patients were followed up 12 months. During follow-up, 2 patients developed shoulder adhesion, which recovered after rehabilitation exercise. At 12 months after operation, the VAS score was significantly lower, the Constant-Murley score was significantly higher, and the range of motion of the shoulder joint (forward flexion and upward lift, abduction and upward lift, and external rotation) significantly increased when compared with preoperative ones (P<0.05). X-ray films showed that the CCD was 8.4 (7.3, 9.4) and 9.2 (8.1, 10.1) mm at 3 days and 12 months after operation, respectively, with a significant difference (Z=−4.665, P<0.001). During follow-up, there was no complication such as infection, titanium plate entrapment, fracture, internal fixation failure, or redislocation. Conclusion The treatment of acute acromioclavicular joint dislocation with TightRope system combined with Locking-Loop biplane anatomical reconstruction has the advantages of small incision, joint reduction under direct vision, high fixation strength, and low incidence of postoperative complications, which can effectively relieve the pain of patients’ shoulder joint and facilitate the recovery of shoulder joint function.
