Summary
Minimally invasive robotic-assisted fixation for acute acromioclavicular joint dislocation significantly improves shoulder function and reduces pain. This TiRobot-assisted technique demonstrates safety and efficacy for treating AC joint injuries.
Area of Science:
- Orthopedic Surgery
- Robotic-Assisted Procedures
- Trauma Management
Background:
- Acute acromioclavicular (AC) joint dislocation is a prevalent orthopedic injury impacting shoulder function and quality of life.
- Effective treatment is crucial for restoring function and alleviating pain associated with AC joint dislocations.
Purpose of the Study:
- To evaluate the short-term clinical efficacy, feasibility, and safety of minimally invasive closed-loop double endobutton fixation assisted by the TiRobot system for AC joint dislocation.
Main Methods:
- Retrospective analysis of 19 patients treated with TiRobot-assisted closed-loop double Endobutton fixation for AC joint dislocation.
- Assessment of Visual Analog Scale (VAS) pain scores, Constant Murley Score (CMS), and shoulder abduction range of motion preoperatively and postoperatively.
- Computed tomography (CT) analysis of acromioclavicular joint parameters at various postoperative intervals to evaluate fixation stability and tunnel integrity.
Main Results:
- Significant improvements in postoperative VAS, CMS, and shoulder abduction compared to preoperative values (P<0.05).
- No significant changes in most CT parameters at early follow-up points, with some tunnel diameter changes noted at later stages.
- Absence of complications including infection, neurovascular damage, fixation failure, or significant loss of reduction.
Conclusions:
- TiRobot-assisted closed-loop double endobutton fixation is an effective and safe treatment for acute AC joint dislocation.
- This robotic-assisted approach offers accurate localization, minimal invasiveness, and promotes good shoulder function recovery.
