Carpal tunnel decompression (Mini Open)

Carpal tunnel syndrome is a condition involving compression of the median nerve within the carpal tunnel of the wrist, due to a raised pressure within this compartment.

Compression of the median nerve leads to symptoms of pain, numbness, and pins and needles in the fingers and accounts for 90% of all nerve compression syndromes.

Carpal tunnel syndrome can be treated conservatively initially with a wrist splint (commonly worn at night) alongside physiotherapy and various training exercises.

Corticosteroids injections can also be trialed. They are administered directly into carpal tunnel to reduce swelling and in turn symptoms.

Surgical treatment is undertaken only when previous treatments have failed.
Carpal tunnel release surgery decompresses the carpal tunnel, involving cutting through the flexor retinaculum, in turn reducing the pressure on the median nerve and is performed as a day case.
