Surgical release of the carpal tunnel.

A thorough understanding of the normal anatomy and possible anomalies that may exist is important for the surgeon managing median nerve compression at the wrist. Given the high incidence of anatomic variability occurring in and around the carpal canal, open decompression of the median nerve is the preferred surgical technique for treating carpal tunnel syndrome. This approach provides complete visualization of the region, enabling the surgeon to decompress the nerve thoroughly, identify and treat anatomic abnormalities, and protect important neurovascular structures. Open carpal tunnel release is a safe and reliable operation with a high rate of functional improvement and patient satisfaction.
