Injury of the median nerve at the wrist or hand level can be caused by any direct trauma to the area, such as a blunt force or a laceration. It can also be caused by repetitive motion or entrapment of the nerve in a confined space, such as a cast or splint.
Injury of the median nerve can be diagnosed through a physical examination, which may include testing of hand and wrist strength, sensation, and range of motion. Additionally, an imaging test, such as an X-ray or MRI, may be ordered to confirm the diagnosis.
Other potential causes of hand and wrist pain include carpal tunnel syndrome, tendinitis, and arthritis.
Treatment for injury of the median nerve may include rest, pain medications, physical therapy, and/or splinting. In severe cases, surgery may be necessary.
The prognosis of injury of the median nerve depends on the severity of the injury and how quickly it is treated. If treated promptly and appropriately, the prognosis is usually good.
