Nerve Injuries and Nerve Compression Syndrome

Nerve Injuries

Nerves, known as the “electrical wiring” of the body, are responsible for sending signals from the brain to various parts of the body, including the hand and upper extremities. Some nerves carry signals from the brain to make muscles move, while other nerves carry signals back to the brain and relay information such as pain and temperature. Nerves can be damaged from a variety of traumatic injuries including a cut or a stretch. Nerve injuries might present themselves with a difficulty in moving a muscle in the arm or hand or with an altered or absent sensation in a specific part of the hand or fingers. Nerves in the fingers may be easily injured when you suffer a laceration or cut to the finger. There are a multitude of factors that determine how to best treat a nerve injury.

The brachial plexus is the “command center” for upper extremity nerves – all functional nerves of the upper extremity originate from the brachial plexus. The brachial plexus can be injured in a multitude of traumatic situations, and the management of these injuries is very complex. To learn more about brachial plexus injuries, please click here.

Nerve Compression Syndromes

Nerves of the upper extremities can be subject to excessive pressure, known as “compression” or “pinching” of the nerve. This may cause numbness and pain in certain areas of the hand, wrist and fingers. The compression of different nerves may lead to a nerve compression syndrome, such as: carpal tunnel syndrome, cubital tunnel syndrome and radial tunnel syndrome.
