Endoscopic carpal tunnel release (ECTR) offers faster recovery for carpal tunnel syndrome. This study found Chow's two-portal ECTR technique safe and reliable in cadavers, with no vital structure injuries.

Area of Science:

  • Orthopedic Surgery
  • Anatomy
  • Minimally Invasive Procedures

Background:

  • Carpal tunnel syndrome (CTS) is a common condition.
  • Endoscopic carpal tunnel release (ECTR) aims to reduce recovery time.
  • Concerns exist regarding the safety and reliability of ECTR.

Purpose of the Study:

  • To evaluate the safety and reliability of the two-portal endoscopic carpal tunnel release technique described by Chow.
  • To assess potential injuries to vital structures during the procedure.

Main Methods:

  • The Chow two-portal endoscopic carpal tunnel release technique was performed on 20 fresh cadaver specimens.
  • Careful examination for injuries to the ulnar artery, superficial palmar arch, third common digital nerve, and flexor tendons was conducted.

  • Assessment of transverse carpal ligament transection was performed.

    • Main Results:

    • No injuries to vital structures were observed in any of the 20 cadaver specimens.
    • Complete transection of the transverse carpal ligament was achieved in 95% of the specimens.
    • Wrist hyperextension was noted to displace vital structures dorsally and distally.

    Conclusions:

    • The two-portal endoscopic carpal tunnel release technique described by Chow can be reliably performed.
    • This technique appears safe, with no observed injuries to surrounding vital structures in the cadaver model.
    • Specialized instruments enhance the safety of the endoscopic procedure.
