Closed partial rupture of a common digital nerve in the palm: a case report.

Nerve injuries in the upper extremity after trauma are common. Typically nerve damage is the result of traction, crush injury, ischemic insult, or direct laceration of the peripheral nerve. Examination of the literature shows that nerve damage in closed traumatic injury is much less common than in open trauma, especially when this standard is applied to closed nerve injuries distal to the wrist. We report a case of closed partial neurotomy of a common digital nerve.
