title: A Cadaveric Study for the Improvement of Thread Carpal Tunnel Release.
abstract: OBJECTIVE
  The thread carpal tunnel release (TCTR) technique has been improved and offers more precise control in dissecting thread placement. The purpose of this cadaveric study was to test the procedure operationally and verify the modified TCTR anatomically.
  
  
  METHODS
  Eleven unembalmed cadaver wrists underwent the transverse carpal ligament (TCL) release by using the modified TCTR technique. An experienced observer dissected each specimen and assessed for completeness of release under direct visual assessment. Injury to the superficial palmar aponeurosis (SupPA), the Berrettini and common digital nerve branches were also recorded as a secondary outcome.
  
  
  RESULTS
  Eleven out of 11 wrists (100%) underwent the modified TCTR with complete release of the TCL. All 11 wrists were released without damage to any vital neurovascular structure including the Berrettini branch and the common digital nerves. The SupPA remained intact in all 5 wrists performed with the preservation steps.
  
  
  CONCLUSIONS
  The modified TCTR technique demonstrated complete division of the TCL while protecting the SupPA as well as the Berrettini and common digital nerve branches.
  
  
  CONCLUSIONS
  The modified TCTR has the potential to offer a clinically safe and effective minimally invasive procedure for complete carpal tunnel release.
