Summary
Endoscopic and subcutaneous carpal tunnel release significantly increase carpal canal volume and median nerve size. These morphologic changes support their clinical effectiveness compared to open carpal tunnel release.
Area of Science:
- Orthopedic Surgery
- Radiology
- Anatomy
Background:
- Carpal tunnel syndrome is a common condition.
- Surgical release is the primary treatment.
- Minimally invasive techniques are increasingly used.
Purpose of the Study:
- To evaluate morphologic changes after single incision endoscopic and two-portal subcutaneous carpal tunnel release.
- To compare these changes with open carpal tunnel release outcomes.
- To provide a morphologic basis for the efficacy of minimally invasive carpal tunnel release.
Main Methods:
- Magnetic resonance imaging (MRI) was used.
- Multiplanar reformation and 3D reconstruction techniques were employed.
- Measurements included canal volume, carpal arch width, median nerve displacement, and cross-sectional area.
Main Results:
- Both endoscopic and subcutaneous release significantly increased carpal canal volume.
- Both methods markedly increased median nerve cross-sectional area.
- Neither method significantly altered carpal arch width.
Conclusions:
- Endoscopic and subcutaneous carpal tunnel release induce favorable morphologic changes.
- These changes provide a basis for equivalent clinical outcomes to open release.
- Minimally invasive carpal tunnel surgery offers a morphologically sound alternative.
