Abstract

Carpal tunnel release (CTR) is a routine and effective surgical treatment for carpal tunnel syndrome. Dissatisfied patients after CTR are uncommon but present diagnostic and therapeutic challenges. This article discusses the most common reasons for unsuccessful CTR, the appropriate ensuing workup, and current evidence regarding revision surgery. The authors' preferred treatment algorithm for the surgical management of the unsuccessful CTR is presented.

Keywords: Carpal tunnel release; carpal tunnel syndrome; electrodiagnostic testing; hypothenar fat flap; nerve conduction study.
