Volkmann ischemic contracture
Toggle: English / Spanish
Volkmann contracture is a deformity of the hand, fingers, and wrist caused by injury to the muscles of the forearm.
Volkmann contracture occurs when there is a lack of blood flow (ischemia) to the forearm. This usually occurs when there is increased pressure due to swelling, a condition called compartment syndrome.
Injury to the arm, including a crush injury or fracture, can lead to swelling that presses on blood vessels and can decrease blood flow to the arm. A prolonged decrease in blood flow will injure the nerves and muscles, causing them to become stiff (scarred) and shortened.
When the muscle shortens, it pulls on the joint at the end of the muscle just as it would if it were normally contracted. But because it is stiff, the joint remains bent and stuck. This condition is called a contracture.
In Volkmann contracture, the muscles of the forearm are severely injured. This leads to contracture deformities of the fingers, hand, and wrist.
There are three levels of severity in Volkmann contracture:
Mild -- contracture of two or three fingers only, with no or limited loss of feeling
Moderate -- all fingers are bent (flexed) and the thumb is stuck in the palm; the wrist may be bent stuck, and there is usually loss of some feeling in the hand
Severe -- all muscles in the forearm that both flex and extend the wrist and fingers are involved; this is a severely disabling condition
The injury that usually causes this condition is an elbow fracture in children. Other conditions that can cause increased pressure in the forearm include:
The main symptom is pain that does not improve with rest or pain medicines, and continues to get worse with time. If the pressure continues, there will be:
Paleness of the skin
Exams and Tests
The doctor will perform a physical exam. If you have compartment syndrome in the forearm, you will have severe pain when the doctor moves the fingers up and down. Your forearm may be very swollen and shiny. You will feel pain when your forearm is squeezed.
The diagnosis can be confirmed with a test that directly measures pressure in the area. This involves inserting a needle into the affected area. The needle is attached to a pressure meter. There is a specific pressure level that confirms the diagnosis of compartment syndrome.
If there is a forearm or elbow fracture, you should use a sling or splint to keep the area still and raise the arm above heart level. This helps prevent further injury and excessive swelling.
The best treatment is early surgery to release the pressure in the forearm before permanent injury to the muscles and nerves occurs. Surgery to lengthen and sometimes transfer muscles is necessary to try to regain some hand function. But surgery is not as successful as early diagnosis and treatment.
How well a person does depends on the severity and stage of disease at the time treatment is started.
If surgery is done before permanent damage occurs, the outcome is usually excellent. If there is high pressure in the forearm for a long period, the muscles and nerves can be permanently damaged. If a nerve is compressed for longer than 12 to 24 hours, it will usually become permanently damaged.
People with mild muscle contractures involving only a few fingers have a better chance of returning to normal function. People who lose normal function of all the muscles that move the fingers and wrist need major reconstructive surgery and will not have a complete recovery.
The more severe the contracture, the worse the function of the hand and wrist. In severe cases, the hand may not work at all, and you may have a loss of sensation (feeling) in the area.
When to Contact a Medical Professional
Contact your health care provider for an appointment if you have had an injury to your elbow or forearm and have developed swelling, numbness, and pain keeps getting worse.
