Carpal tunnel syndrome

Carpal tunnel syndrome: this condition is a result of abnormal pressure on a nerve (median nerve) that crosses the palm side of the wrist. Swelling of the tendons that flex the fingers can lead to this abnormal pressure.

Conditions such as diabetes, poor thyroid function, recent childbirth, as well as occupations involving repetitive use of the hands and fingers are at risk. Signs/symptoms include pain in the palm of the wrist or the first three fingers, tingling or numbness in the palm of the wrist or first three fingers, loss of finger dexterity or strength. Symptoms typically worst at night.

Treatment

Treatment initially is conservative or nonsurgical and involves limiting the swelling of the tendons surrounding the nerve. Options include wrist splints, anti-inflammatory medicines, steroid injections, and activity modifications.

Surgery

Surgical intervention is reserved for patients who continue to have severe pain despite conservative treatment and involves releasing the tissue which puts the abnormal pressure on the median nerve. An EMG (electromyography) and NCV (nerve conduction velocity test) are important in confirming the diagnosis.
