Arthroscopic surgery can be used to treat a number of conditions of the wrist. This surgical procedure is used to diagnose and treat problems inside a joint.
Arthroscopy utilizes a small fiber optic instrument called an arthroscope that enables the surgeon to see inside the joint without making large incisions into the muscle and tissue.
Since the wrist is a complex joint with eight small bones and many connecting ligaments., arthroscopic surgery can be used to diagnose and treat a number of conditions of the wrist, including chronic wrist pain, wrist fractures, ganglion cysts, and ligament tears.
During this procedure, the surgeon makes small incisions (called portals) through the skin in specific locations around a joint.
These incisions are less than half an inch long. The arthroscope, which is approximately the size of a pencil, is inserted through these incisions. The arthroscope contains a small lens, a miniature camera, and a lighting system.
The three-dimensional images of the joint are projected through the camera onto a television monitor. The surgeon watches the monitor as he or she moves the instrument within the joint.
Probes, forceps, knives, and shavers at the ends of the arthroscope are used to correct problems uncovered by the surgeon.
Many wrist conditions may be corrected utilizing this procedure type, such as:
Chronic Wrist Pain
Arthroscopic exploratory surgery may be used to diagnose the cause of chronic wrist pain when the results of other tests do not provide a clear diagnosis. Often, there may be areas of inflammation, cartilage damage, or other findings after a wrist injury. In some cases, after the diagnosis is made, the condition can be treated arthroscopically as well.
Small fragments of bone may stay within the joint after a bone breaks (fractures). Wrist arthroscopy can remove these fragments, align the broken pieces of bone, and stabilize them by using pins, wires, or screws.
Ganglion cysts commonly grow from a stalk between two of the wrist bones. During an arthroscopic procedure, the surgeon can remove the stalk, which may reduce the change that these cysts will return.
Ligaments are fibrous bands of connective tissue that link or hinge bones. They provide stability and support to the joints. The TFCC is a cushioning structure within the wrist. A fall on an outstretched hand can tear ligaments, the TFCC, or both. The result is pain with movement or a clicking sensation. During arthroscopic surgery, the surgeon can repair the tears.
Carpal Tunnel Release
Carpal tunnel syndrome is characterized by numbness or tingling in the hand, and sometimes with pain up the arm. It is caused by pressure on a nerve that passes through the carpal tunnel. (The carpal tunnel is formed by the wrist bones and a thick tissue roof.) Pressure can build up within the tunnel for many reasons, including irritation and swelling of the tissue (synovium) that covers the tendons.
If the carpal tunnel syndrome does not respond to nonsurgical treatment, one option is to repair the area surgically. The surgeon would cut the ligament roof and enlarge the tunnel. This would reduce pressure on the nerve and relieve symptoms. This can sometimes be done using an arthroscope.
