Abstract
Purpose
The presence of aberrant anatomy during a limited-open carpal tunnel release does not require conversion to an open procedure. We describe the occurrence of aberrant anatomy seen during limited-open carpal tunnel release, and suggest the safest way to proceed with carpal tunnel release once aberrant anatomy is encountered.
Methods
A retrospective chart review was completed for patients who underwent limited-open carpal tunnel release between January 2000 and June 2007. The surgical record was examined to determine if any aberrant anatomy was encountered during the procedure.
Results
Of the 1,227 hands operated on, 69 anomalies were identified. Two carpal tunnel releases were converted to open releases after it was determined that the aberrant motor branches precluded safe release with a limited-open technique Conclusions An understanding of anatomical variations combined with vigilance and careful dissection enhances the chance for safe and effective limited-open carpal tunnel release.
