ABSTRACT
Carpal tunnel syndrome is the most common nerve entrapment syndrome in the United
States. Carpal tunnel release is usually curative, but failure or incomplete relief
of symptoms may be seen in 1.6 to 25% of patients following surgery. Failure may be
divided into either persistent or recurrent carpal tunnel symptoms. Potential etiologies
and the evaluation of failed carpal tunnel surgery are described. Nonoperative and
operative treatment options, which address possible underlying causes, are discussed.
The results of revision carpal tunnel surgery are reviewed and are less predictably
good compared to primary carpal tunnel release.
