Volkmann contracture

Definition

Volkmann contracture is a deformity of the hand, fingers, and wrist caused by injury to the muscles of the forearm. The condition is also called Volkmann ischemic contracture.

Causes

Volkmann contracture occurs when there is a lack of blood flow (ischemia) to the forearm. This 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 decreases blood flow to the arm. A prolonged decrease in blood flow injures 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:

Conditions that can cause increased pressure in the forearm include:

Symptoms

Symptoms of Volkmann contracture affect the forearm, wrist, and hand. Symptoms may include:

Exams and Tests

The health care provider will perform a physical exam, focusing on the affected arm. If the provider suspects Volkmann contracture, detailed questions will be asked about past injury or conditions that affected the arm.

Tests that may done include:

Treatment

The goal of treatment is to help people regain some or full use of the arm and hand. Treatment depends on the severity of the contracture:

Outlook (Prognosis)

How well a person does depends on the severity and stage of disease at the time treatment is started.

Outcome is usually good for people with mild contracture. They may regain normal function of their arm and hand. People with moderate or severe contracture who need major surgery may not regain full function.

Possible Complications

Untreated, Volkmann contracture results in partial or complete loss of function of the arm and hand.

When to Contact a Medical Professional

Contact your provider right away if you have had an injury to your elbow or forearm and have developed swelling, numbness, and pain keeps getting worse.
