What Is Carpal Tunnel Syndrome?

By: Jeffrey N. Guttman, M.D.

Jeffrey Guttman is a diligent and detail-oriented orthopedic surgeon based in Westbury, NY. He earned his degree in medicine from New York University. He then completed his residency in orthopedic surgery at St. Luke’s-Roosevelt Hospital and a fellowship in sports medicine at Allegheny University Hospitals. He also holds a bachelor’s from the University of Pennsylvania. He is a board certified physician specializing in orthopedic surgery and orthopedic sports medicine.

The term carpal tunnel syndrome describes a condition that arises when the median nerve, which runs from the forearm into the hand, is compressed at the wrist by a tendinous band. Compression of this nerve can result in pain, weakness, and numbness involving the wrist and hand (mostly involving the thumb, index, middle, and ring fingers).

What Causes Carpal Tunnel Syndrome?

In most cases, no specific etiology can be identified. However, patients who perform repetitive manual tasks (such as assembly line work), or construction workers that use vibrating hand tools are at increased risk of developing carpal tunnel syndrome. The development of carpal tunnel syndrome has been associated with trauma, obesity, pregnancy, multiple myeloma, hypothyroidism and amyloidosis.

How Is Carpal Tunnel Syndrome Discovered?

Symptoms may be bilateral or unilateral. Patients frequently complain of hand weakness (particularly in grip), hand clumsiness and hand numbness. Many patients note a painful numbness in the affected hand while sleeping at night. In severe cases there can be atrophy of the hand muscles. Once these symptoms are brought the attention of a physician, an electromyogram (EMG) and nerve conduction velocities (NCV) can be obtained to confirm the diagnosis.

How Is Carpal Tunnel Syndrome Treated?

Non-surgical management, usually tried in patients with new onset mild symptoms, involves rest, occasional splinting of the hand and wrist, and non-steroidal anti-inflammatory drugs. Steroid injections into the carpal tunnel can provide temporary relief of symptoms. Surgery, usually reserved for more severe or recurrent symptoms, involves incision at the wrist and sectioning of the transverse carpal ligament compressing the median nerve.
