NC55/S64 Injury of nerves at wrist or hand level



Injury to nerves at the wrist or hand level is usually caused by trauma, such as a fall, car accident, or other sudden impact. It may also be caused by repetitive stress or movement, entrapment, or pressure on the nerve.


Diagnosis of nerve injury is typically done through a physical examination, which may include testing of nerve strength and sensation. An x-ray, CT scan, or MRI may also be used to determine the extent of the injury.

Differential diagnosis

Differential diagnosis for nerve injury at the wrist or hand level may include carpal tunnel syndrome, radial nerve palsy, ulnar nerve palsy, and Guyon’s canal syndrome.


Treatment for nerve injury may include rest, splinting, pain medications, physical therapy, and in some cases, surgery.


Prognosis for nerve injury depends on the severity and extent of the injury. Most injuries with appropriate treatment can improve over time, although some may require more invasive treatments.
