Initial experience with endoscopic carpal tunnel release surgery.
A retrospective analysis of patients who underwent endoscopic carpal tunnel release (ECTR) surgery at the authors' institution during the past 18 months was performed. Twenty-six ECTR surgeries were performed in 24 patients. Eighty-seven percent of patients experienced significant improvement or resolution of their symptoms following ECTR. Of the patients in whom surgery failed, those who have undergone postoperative assessment of nerve conduction velocities have experienced improvement or normalization. Three patients (12.5 %) underwent ECTR after a previous open procedure in the contralateral hand; all three patients preferred the ECTR procedure. One significant complication, a lacerated ulnar artery, was noted. It is concluded that ECTR is a promising technique that appears to have similar efficacy to open CTR and has the potential to be a superior technique.
