Nerve injuries in the hand are serious. If left untreated, they can severely affect the mobility, strength and feeling in your hand. Nerves transmit the electrical signals to enable hand movement, and they are an important component in a person’s sense of touch.
The human hand has three nerves: median, ulnar and radial. The hand also very sensitive touch receptors – an astonishing 17,000 – and free nerve endings in the palm. These receptors receive information from the environment, such as sensations of pressure, movement and vibration. The nerves in the hand can be damaged due to trauma, including lacerations, crushing, over extension or twisting injuries. They can also be damaged by inflammation and some chronic conditions.
Nerves carry both sensory and motor signals to and from the brain. Some common symptoms of nerve damage include the following:
If any of these symptoms are present, a visit with a hand specialist is recommended.
A hand specialist will do a physical exam of the hand, including observation of mobility, weakness or pain. The doctor may also conduct tests, such as x-ray, CT (computerized tomography) scan, MRI (magnetic resonance imaging), ultrasound, or EMG (Electromyography).
Treatments for nerve damage in the hand can range from splitting, therapy and rest, to surgery, depending on the type and extent of damage. A pressure or stretching injury, for example, may resolve on its own with proper supportive care, like splinting and therapy, to keep the joints flexible while the nerve injury heals. Nerves that have been completely severed, however, may require surgery to reconnect the broken nerve fibers.
