Early results of conventional versus two-portal endoscopic carpal tunnel release. A prospective study

Abstract

The authors compare in a prospective, randomized study the early outcome of carpal tunnel release using either a conventional palmar open release (n = 40) or a two-portal endoscopic release (n = 56). Both groups were similar. No statistically significant differences were found regarding pain, disappearing of paraesthesiae or time to return to work. However, better recovery of grip strength was observed in the endoscopic group at 1 and 3 months. No surgical complications were observed in either group.
