How is carpal tunnel surgery done exactly?

Small incision...: The most common way is to numb the area up (usually with a regional block to make the who arm numb). A small incision is made near the wrist, and the band of connective tissue (flexor retinaculum) that is squeezing on the median nerve is opened up to release the nerve. The wound is then sewed up...And you're done!

Open or endoscopic: Surgery for carpal tunnel syndrome (cts) involves cutting the transverse carpal ligament (tcl). Open capal tunnel release utilizes direct visualization of the tcl, which is then cut through a palmar skin incision. Endoscopic carpal tunnel release uses a small wrist incision to enter the carpal tunnel with an endoscope. The tcl is incised through the scope with a retractable endoscopic knife.
