Summary
This study introduces a minimally invasive open carpal tunnel release technique. This method uses specialized instruments for direct visualization and avoids injury to critical structures, with no reported complications since 1997.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Minimally Invasive Procedures
Background:
- Controversy exists regarding optimal surgical approach for carpal tunnel release (arthroscopic vs. open).
- Traditional open release offers direct visualization but may involve larger incisions.
- Arthroscopic techniques aim for smaller incisions but can have limitations in visualization and risk of nerve injury.
Purpose of the Study:
- To present a novel, minimally invasive open carpal tunnel release technique.
- To evaluate the safety and efficacy of this technique using specialized instruments.
- To retain the benefits of direct visualization while minimizing surgical trauma.
Main Methods:
- Development of specialized instruments including a thin metal guide and an angled knife holder.
- Performance of open carpal tunnel release through a small incision using these instruments.
- Procedure performed and monitored since 1997.
Main Results:
- The described method allows for direct visualization of the carpal tunnel pathology.
- The technique successfully avoids complications related to injuries of important anatomical structures.
- No complications have been reported in procedures performed since 1997.
Conclusions:
- This minimally invasive open carpal tunnel release technique is a safe and effective alternative.
- The specialized instruments facilitate precise dissection and reduce the risk of iatrogenic injury.
- The technique preserves the advantages of open surgery with reduced morbidity.
