Long-term outcomes of carpal tunnel release: a critical review of the literature.

Abstract

Carpal tunnel release (CTR) is widely accepted as an effective surgical treatment method for idiopathic carpal tunnel syndrome. While the short-term literature is well substantiated, the "long-term" literature has rarely exceeded 2 years of follow-up, which may be inadequate for a chronic and potentially recurring disease such as carpal tunnel syndrome. An English language literature search for long-term outcomes research on carpal tunnel release was made. Long-term is defined as 2 years or more after surgery. CTR is a highly effective procedure, but important aspects remain poorly understood, including recurrence and existing electromyographic data. Some study design issues exist with the current literature. Further high-quality research is needed.
