Factors that determine reexploration treatment of carpal tunnel syndrome.

Abstract

Eighteen patients (20 hands) underwent reexploration of the carpal tunnel after a primary carpal tunnel release. The patients complained of unrelieved symptoms after their initial surgical procedures. We recommend reexploration for patients with unrelieved carpal tunnel syndrome if they have a positive Phalen's test, have symptoms that cause nocturnal wakening or are exacerbated by activities, or have a short or transverse initial incision. If the incision is adequate and these symptoms are not present, we believe that reexploration will not result in a satisfactory outcome.
