[Endoscopic decompression of the carpal tunnel]

The aim of the study was to evaluate the efficiency and safety of endoscopic carpal tunnel release using the Wolf one-portal system. The case records for all decompressions performed between January 1995 and June 1998 were reviewed retrospectively. Preoperative complaints, intraoperative findings and postoperative results were recorded for a total of 168 procedures in 138 patients. The median follow-up period was 10.4 weeks (1.1-170.9). An improvement in symptoms was noted after 82.9% of the procedures. The complication rate was 8.9% at the time of follow-up. Nine procedures were converted to open release. No patients sustained nerve or vascular injury. The findings in this study indicate that carpal tunnel release performed using the Wolf one-portal system provides a safe and effective treatment for carpal tunnel syndrome. The technique is today used as a routine in the department in uncomplicated cases of carpal tunnel syndrome.
