The ulnar nerve runs from your shoulder down the arm and into the little and ring fingers. It provides sensation in the associated fingers and assists with fine movements in the hand. The ulnar nerve may become entrapped and dysfunctional, causing weakness and a loss of sensation in your hands and fingers on the affected side. A loss of ulnar nerve functionality can be treated nonsurgically or surgically, with the goal of resuming full functionality.
Ulnar Nerve Entrapment
Ulnar nerve entrapment occurs when the nerve becomes compressed, resulting in dysfunction. Symptoms include numbness and tingling in the ring and little fingers, a weak grip, poor finger coordination or muscle wasting in the hand if the nerve has been compressed for a long time. According to the American Academy of Orthopaedic Surgeons, ulnar nerve compression may occur as a result of a previous elbow fracture, large bone spurs that press on the nerve or swelling of the elbow joint. In addition, a direct hit on the inside of the elbow, pressing or leaning on the elbow for long periods of time or a frequent activity that requires a lot of bending at the elbow can irritate a compressed ulnar nerve.
What To Do
If you have symptoms of ulnar nerve compression like numbness, tingling and weakness, see a doctor right away. Don't prolong a problem that may interfere with your normal daily activities when it can be easily treated. Prompt medical treatment may mean the difference between a return to full functionality and permanent damage.
Treatment
Your current physical condition determines the type of treatment for ulnar nerve entrapment that results in a loss of function. According to the American Academy of Orthopaedic Surgeons, nonsurgical treatment is usually the initial route. Your doctor might recommend using an over-the-counter anti-inflammatory medicine like ibuprofen to minimize swelling around the ulnar nerve. The doctor may also refer you to a physical therapist to do exercises that help with arm, wrist and hand flexibility and strength. If your symptoms don't improve or there is severe nerve compression, you may need surgery to relieve pressure.
Prevention
To prevent ulnar nerve entrapment and loss of function, avoid putting extended pressure on your elbow or palm. For example, don't lean on your elbows when using a computer. Keep your elbow straight when you are sleeping by wrapping a towel around your elbow or strapping on an elbow pad. Finally, make sure casts and splints fit correctly so they aren't pressing on your nerve.
