Nerve Injuries

Penetrating wounds to the palmar surface of the hand or fingers may result in lacerations (cuts) to the critical digital nerve compartments, which lie just underneath the skin. In the fingers and thumb, nerves provide only sensory function. Nerves at the wrist and hand level provide both sensory and motor functions. Symptoms after nerve laceration include loss of sensation, motor loss, as well as pain at the site of laceration secondary to neuroma formation. Treatment involves surgical repair of the lacerated digital nerve. Repair attempt of lacerated nerves involve microsurgical techniques to optimize the repair and minimize scar. In certain situations, use of synthetic nerve tubes can be employed to bridge gaps and/or minimize scar formation about the site of the nerve repair. The results after nerve repair are relative to the competence of the repair, site of the nerve injury, and the age of the patient.
