Carpal Tunnel Syndrome

Common symptoms of carpal tunnel syndrome are numbness and tingling in the hand, especially at night; pain with prolonged gripping such as holding a steering wheel; or clumsiness in handling objects. Sometimes the pain can go all the way up to the shoulder.

These symptoms are caused by pressure on the median nerve as it enters the hand through a tunnel in the wrist. The tendons that bend your fingers and thumb also travel in this tunnel.

Mild cases can be treated with a splint or brace to rest the wrist. Those cases that do not respond to nonsurgical treatment and those that are diagnosed late often require surgery. This is generally done in an outpatient setting.

Dupuytren's Contracture

Dupuytren's contracture is a hereditary thickening of the tough tissue called fascia that lies just below the skin of your palm. This condition may vary from small lumps or bands to very thick bands which may eventually pull the fingers into the palm.

Dupuytren's disease is familial, and may be associated with cigarette smoking, vascular disease, epilepsy, and diabetes.

The mainstay of treatment is surgical and is recommended if there is progressive contracture drawing the fingers into the hand. Sometimes a steriod injection will be used in a painful nodule. Small nodules or lumps in the palm do not need treatment until they are very large and interfere with hand function. Even with successful surgical removal, the bands may reappear or occur in other fingers.

Ganglion Cysts

Ganglion cysts are the most common mass or lump in the hand. They are most common on the back of the wrist. These non-cancerous, fluid-filled cysts arise from the ligaments, joint linings, or tendon sheaths when they are irritated or inflamed. If the cyst is painful, interferes with function or the patient does not like the appearance, your orthopaedic surgeon can remove the fluid with a needle (aspiration) or remove it surgically.

Trigger Finger

Trigger finger is an irritation of the digital sheath which surrounds the flexor tendons. When the tendon sheath becomes thickened or swollen it pinches the tendon and prevents it from gliding smoothly.

Sometimes the swelling can be treated with rest, activity modification, oral anti-inflammatories, or steroid injections. The tendon sheath will then return to its normal, pain-free condition. More severe cases may require surgery to release the tendon. This can be done as an outpatient procedure.
