Ulnar nerve innervates several muscles in the hand. Its damage reflects in inappropriate movements of hand and fingers. The ulnar nerve is actually not protected by structures such as bones or muscles. This is why it is prone to injury along its whole length. The nerve can be damaged due to numerous causes and if left untreated the consequences may be rather severe.

Causes of Ulnar Nerve Damage

Ulnar nerve starts in the shoulder and ends in wrist. It may be trapped or pinched all the way this path. So, direct trauma to the nerve is only one of the causes of the damage. Injury may be direct or indirect. The injury may also affect cervical spine and plexus brachialis which are the originating place of the ulnar nerve. Bone fractures can directly damage the nerve and this particularly refers to fractures of the elbow since ulnar nerve passes right next to the elbow joint. Apart from the previously mentioned, additional causes of the damage include diabetes, tumors, rheumatism, hypothyroidism and clod clots in the vessels which are in charge with blood supply of the nerve.Symptoms of Ulnar Nerve Damage

The leading symptom of ulnar nerve damage is numbness of the little and ring finger. The numbness intensifies if elbow is bent.

Patients may also complain about severe pain in the elbow. The pain may prevent movements and patients may have difficulties when trying to hold or carry different objects. Even driving or holding a phone may be painful and difficult to perform.

Sometimes the pain and feeling of numbness may resemble the symptoms which occur in carpal tunnel syndrome. However, carpal tunnel syndrome develops due to the injury of median nerve.

Treatment for Ulnar Nerve Damage

The goal of the therapy is to restore the movements in the hand and fingers. Sometimes these movements cannot be as they used to be but at least the hand and the fingers are functioning.

In injuries, a splint or a pad are used to support the elbow. They may accelerate the healing and prevent further damage of the nerve. To reduce inflammation patients are given corticosteroid injections. Pain can be alleviated by different painkillers and analgesics. If symptoms do not withdraw the patient needs to be operated. The surgery is performed only in patients whose symptoms cannot be improved by conservative treatment.

Exercises and physical therapy may be of great help. They can maintain the strength of the muscles and restore movements in the hand and fingers to certain extent.
