Ulnar tunnel syndrome

Ulnar Tunnel Syndrome is a condition that affects the ulnar nerve in the wrist. The ulnar nerve is one of the three main nerves in the arm. It travels from the neck down into the hand, and can be constricted in several places along the way, such as beneath the collarbone or at the wrist. The most common place for compression of the nerve is behind the inside part of the elbow. Ulnar tunnel syndrome, also known as ulnar nerve entrapment, occurs when the ulnar nerve in the arm becomes compressed or irritated.

Causes

The ulnar nerve can be constricted by a number of factors, including:

• Physical trauma to the area
• Repetitive strain injury (RSI)
• Bone spurs
• Cysts
• Tumors

Symptoms

Symptoms of ulnar tunnel syndrome can vary, depending on the severity of the condition. They may include:

• Pain
• Numbness
• Tingling
• Weakness
• Muscle atrophy

Diagnosis

Diagnosis of ulnar tunnel syndrome typically involves a physical examination and may also include:

• Nerve conduction studies
• Electromyography (EMG)
• Magnetic resonance imaging (MRI)

Treatment

Treatment for ulnar tunnel syndrome can range from conservative to surgical, depending on the severity of the condition. Treatment options may include:

• Physical therapy
• Medication
• Surgery
