Summary
A new reusable median nerve protector for endoscopic carpal tunnel release (ECTR) proved safe and effective. It improved patient symptoms, function, and grip strength with minimal complications, enhancing neurovascular visualization during surgery.
Area of Science:
- Orthopedics
- Neurosurgery
- Surgical Innovation
Background:
- Carpal tunnel syndrome (CTS) affects median nerve function.
- Endoscopic carpal tunnel release (ECTR) is a minimally invasive surgical option.
- Protecting the median nerve during ECTR is crucial for preventing iatrogenic injury.
Purpose of the Study:
- To design and evaluate a novel reusable median nerve protector for ECTR.
- To assess the safety and efficacy of this device in patients with CTS.
Main Methods:
- Prospective evaluation of 72 patients (97 palms) undergoing ECTR with the new protector.
- Postoperative follow-up at 1, 3, 6, 12, and 24 weeks.
- Assessment using symptom severity, functional status, wound pain, scar tenderness, sensory mapping, grip strength, and pinch strength.
Main Results:
- No iatrogenic neurovascular injuries or hematomas occurred.
- Significant improvements in symptom severity and functional status scores were observed by 6 weeks.
- Enhanced sensory mapping, grip strength, and reduced scar tenderness were noted postoperatively.
Conclusions:
- The reusable median nerve protector is a safe and reliable tool for single-portal ECTR.
- It facilitates clear visualization of neurovascular structures.
- This device contributes to successful patient outcomes in carpal tunnel surgery.
