Endoscopic carpal tunnel release safety is concerning due to potential nerve and vessel damage. This study mapped carpal tunnel anatomy using cadavers to assess risks associated with endoscopic tools.

Area of Science:

  • Anatomy
  • Surgical Techniques
  • Medical Device Safety

Background:

  • Endoscopic carpal tunnel release is widely used.
  • Concerns exist regarding potential neurovascular complications.
  • Accurate anatomical knowledge is crucial for safe surgical practice.

Purpose of the Study:

  • To investigate the detailed topography of the carpal tunnel.
  • To evaluate the in situ spatial relationship of an endoscopic blade assembly within the carpal tunnel.
  • To identify potential risks associated with a specific one-portal endoscopic system.

Main Methods:

  • Anatomical dissection of fresh cadaver hands.
  • Plastination technique for detailed serial cross-section analysis.
  • Modified Spalteholz staining for whole-specimen visualization of the blade's position.

Main Results:

  • Detailed topographical mapping of carpal tunnel structures was achieved.
  • The precise in situ location of the endoscopic blade assembly was visualized.
  • Potential for critical structure injury was assessed through detailed anatomical relationships.

Conclusions:

  • The study provides critical anatomical data for assessing endoscopic carpal tunnel release safety.
  • Understanding the topography aids in minimizing risks of nerve, tendon, or vessel division.
  • This research supports the refinement of endoscopic surgical techniques and device design.
