If conservative treatment is not effective, surgical intervention may be chosen. Surgery can be done as an open procedure or endoscopically.
In endoscopic surgery, a small incision is made in the wrist and a dilator tube is inserted. An arthroscope with a camera is inserted in order to view the anatomy, then a cutting tool is used to sever the transverse carpal ligament in order to reduce pressure on the median nerve.
This type of surgery is less invasive and allows for faster recovery and less postoperative pain.
