Novel 3-point positioning technique combined with the TightRope system for treating acute Rockwood type III acromioclavicular joint dislocation

BACKGROUND The TightRope system is a common strategy for treating acute Rockwood type III acromioclavicular joint dislocation (ACJD). However, it requires frequent intraoperative fluoroscopy, which poses potential risks to both patients and operators. A novel 3-point positioning technique was developed to reduce intraoperative fluoroscopy time. AIM To evaluate the efficacy of the 3-point positioning technique combined with the TightRope system in acute Rockwood type III ACJD. METHODS Between January 2024 and October 2024, 26 patients with acute Rockwood type III ACJD underwent treatment via the 3-point positioning technique combined with the TightRope system. Demographic characteristics, operative parameters, and follow-up data were recorded. Preoperative and postoperative clinical evaluations were performed and compared. RESULTS The study included 26 patients, 19 males and 7 females, with a mean age of 41.04 ± 12.93 years. The average intraoperative fluoroscopy time was 8.31 ± 1.54 seconds, and the median follow-up period was 13 months. At the final follow-up, significant improvements in the scores were observed relative to preoperative measurements, with all comparisons yielding statistical significance (P < 0.05). The overall complication rate was 3.85%. CONCLUSION The 3-point positioning technique combined with the TightRope system reduces intraoperative fluoroscopy time and provides a safe and effective treatment option for patients with acute Rockwood type III ACJD.
