Summary
Navigated suture button implantation for AC joint dislocations is a feasible surgical technique. This method shows potential for reduced invasiveness and improved precision in stabilizing acute traumatic AC joint injuries.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Traumatology
Background:
- Surgical treatment for acute traumatic AC joint dislocations remains debated.
- Arthroscopically assisted suture button stabilization is a common, minimally invasive technique.
- This study introduces navigated suture button implantation for enhanced precision.
Purpose of the Study:
- To evaluate the feasibility of navigated suture button implantation for AC joint dislocations.
- To assess the potential for reduced surgical invasiveness and increased precision.
- To compare outcomes with conventional methods in future studies.
Main Methods:
- Prospective study of 10 patients with Rockwood 3b/5 AC joint injuries.
- Surgical stabilization using a suture button system via a navigated coracoclavicular drill tunnel.
- Data collection included demographics, radiology, and patient-reported outcomes (DASH, NHS, Eq. 5D) pre- and postoperatively.
Main Results:
- Operations performed within 8.8 days post-trauma; average operative time 50.3 minutes.
- No statistically significant loss of reduction observed in vertical coracoclavicular distance.
- Significant improvements in DASH, NHS, and Eq. 5D scores from discharge to 3 months postoperatively.
Conclusions:
- Image-guided 3D C-arm navigated AC joint stabilization is feasible in surgical practice.
- This technique may reduce invasiveness and improve implant positioning accuracy.
- Further studies with larger cohorts and longer follow-up are needed for comparison.
