How is claw hand diagnosed?

Doctors can make a diagnosis of claw hand based on the appearance of your fingers. However, your doctor may perform tests to determine the cause and severity of the condition.

Your doctor may ask you questions about your medical history to determine if a past injury or illness is the cause of your symptoms. Your doctor may ask you to bend your fingers and grasp objects, in addition to other tests, to see how much strength and flexibility you have in your fingers and hand.

An electromyography (EMG) test checks how well your nerves are working. To perform an EMG, your doctor will insert thin needles through your skin into the muscles of your hand. The needles connect to a machine that measures electrical impulses from your nerves when you move. You may feel a little bit of discomfort from the small needles, but it’s usually mild. You may also have slight bruising or experience minor soreness for a few days after the test.

If the EMG test results show that you have abnormal nerve activity, your doctor may run more tests to determine the cause of your nerve damage. The tests your doctor will perform depend on your medical history and any other symptoms you may be experiencing.

How is claw hand treated?

The treatment for claw hand includes both non-surgical and surgical methods, and this depends on the cause of claw hand.

  • Nonsurgical treatment measures for acquired form of claw hand include:
  • Non-steroidal anti-inflammatory oral medications, such as indomethacin and naproxen, may be used to help decrease the pain and swelling
  • Complete immobilization of the hand with a cast may be required, to restrict movement
  • Corticosteroid injections may help provide temporary relief of symptoms and improve the range of motion
  • Physical therapy: After symptoms have abated, it is important to begin some light motion exercises. Physical therapy may help restore strength, flexibility, and function of the hands. This can be used for congenital form of claw hand also

Surgical treatment measures for claw hand involve fixing the underlying issues contributing to the deformity. This can include nerve problems, tendon abnormalities, or scar tissue. You may need surgery to repair damaged nerves, ligaments, or muscles that are the cause of your symptoms. If your injury is due to tight skin, as is seen in people who have burn injuries, skin grafts and surgery to remove scar tissue may be necessary. Multiple surgeries may be necessary for serious defects and for burn injuries.
