MGH patient tests positive for malaria. A patient admitted to Massachusetts General Hospital amid concerns he might have Ebola tested positive for malaria, with an initial test for Ebola coming back negative, the hospital said. But doctors were not ready to rule out Ebola because the first test sometimes fails to detect the deadly virus.

Volkmann's Ischemic Contracture - Compartment Syndrome


Overview, Causes, & Risk Factors

Compartment syndrome occurs when blood supply is dramatically reduced to muscles in a closed body space, known as a compartment. Compartments are found in the hand, forearm, upper arm, abdomen, buttock, and leg. The muscles most frequently involved are those on the front of the lower leg or the palm side of the forearm.

What is going on in the body?

A muscle group is surrounded by a tough, fibrous membrane called the fascia. Small blood vessels supply the muscle with oxygen and other essential nutrients. Insufficient blood supply to tissues and compartment syndrome can occur if:

  • the muscle compartment size is reduced, as when a cast is too tight
  • the muscle compartment contents are increased, such as by swelling or bleeding associated with injury
  • If the affected muscles are deprived of blood supply for more than 6 hours, nerve and muscle tissue can be permanently damaged or destroyed.

    What are the causes and risks of the condition?

    Some common causes of compartment syndrome include:

  • bleeding, from a bone fracture or other injuries
  • the amount of body surface area, also called BSA, that is injured\ \the depth of destruction\ \the location of the burn\ ',CAPTION,'Burns');" onmouseout="return nd();">burns
  • casts applied to treat bone fractures or other abnormalities
  • a crush injury
  • intense exercise
  • leaking of intravenous fluid or injections into the compartment
  • repeated use of a muscle group
  • seizures that involve the muscles in the compartment
  • snakebite
  • swelling of the muscle itself

  • Symptoms & Signs

    What are the signs and symptoms of the condition?

    The person will usually complain of increasingly severe, constant pain in the affected muscles. Often the degree of pain seems more than expected for the severity of the injury. Other symptoms of compartment syndrome include:

  • decreased pulses below the affected area
  • difficulty making the muscle move
  • intense pain with stretching of the muscle
  • numbness in the skin
  • pale skin
  • swelling and tenderness of the muscle
  • Intermittent compartment syndrome can occur. A runner with this condition may complain of tightness and aching in the calf muscles. The person may run a relatively short distance and need to stop due to discomfort. The tightness gradually goes away after the person stops running.


    Diagnosis & Tests

    How is the condition diagnosed?

    Diagnosis of compartment syndrome begins with a medical history and physical exam. The raised pressure within the compartment can be measured with specialized instruments.


    Prevention & Expectations

    What can be done to prevent the condition?

    Acute compartment syndrome can sometimes be avoided by early stabilization of a fracture. This may involve splinting, elevating the injured limb on a pillow, and applying ice to reduce swelling. If a person has a cast, circulation to the area below the cast will be checked frequently. If circulation is impaired or the person has severe pain, the healthcare provider may choose to cut the cast to relieve pressure.

    What are the long-term effects of the condition?

    If compartment syndrome is untreated, death of the muscles can occur. Muscles can become inactive and excessively tight. Toes or fingers may become fixed in a curled position with permanent numbness. Severe tissue death may lead to the need for amputation of the affected limb.

    What are the risks to others?

    Compartment syndrome is not contagious and poses no risk to others.


    Treatment & Monitoring

    What are the treatments for the condition?

    Diagnosis must be made accurately and promptly to assure a good outcome. Initial treatment consists of elevating the limb above the level of the heart. If a cast has been applied, it is removed. A surgical procedure known as a fasciotomy may be used to open the membrane leading to the affected muscles. Pressure is relieved, and the blood flow can return to normal. Often the skin needs to be left open for a few days. It can be closed with sutures or a skin graft after the swelling goes down.

    What are the side effects of the treatments?

    Surgery can cause bleeding, infection, or allergic reaction to anesthesia. The muscle and nerves may not return to normal after recovery.

    What happens after treatment for the condition?

    A scar may appear where the skin was left open following surgery.

    How is the condition monitored?

    Any new or worsening symptoms should be reported to the healthcare provider.
