Compartment syndrome

What is compartment syndrome?

Compartment syndrome is a painful condition caused by high pressure in a group of muscles (a muscle compartment), most commonly in the leg. High pressure can be caused by bleeding or swelling. When pressure reaches dangerous levels, it reduces blood flow, oxygen and nourishment to nerves and cells.

What is a compartment?

A compartment is a group of muscles enclosed in a tough sheath called fascia keeping the muscles together.

The sheath does not stretch easily, so if there is a build-up of blood or fluid inside the compartment, pressure can build up.

What are the types of compartment syndrome?

Compartment syndrome can be acute or chronic.

Acute compartment syndrome usually happens suddenly after severe injury. It is extremely painful and needs urgent treatment to prevent permanent damage.

Chronic compartment syndrome happens gradually, and is reversible. It is a rare condition that occurs more often in the legs than the arms.

What causes compartment syndrome?

You can develop acute compartment syndrome after serious injury such as bone fracture, crush injury (for example, from a car accident) or surgery. It is extremely painful.

Other causes include:

• very tight bandages or plaster casts
• snake bite
• severe burns
• severe bruising
• anabolic steroid use
• blood flow building up after blocked circulation

Repetitive exercise, such as running, cycling or rowing, can cause chronic compartment syndrome.

What are the symptoms of compartment syndrome?

Acute compartment syndrome symptoms include:

• intense pain — more painful than you might expect from your injury
• increased pain and a feeling of tightness when you stretch affected muscles
• pale, cold skin
• a tingling or burning sensation in your skin
• numbness and paralysis

Chronic compartment syndrome symptoms include:

• pain or cramping during exercise that stops once the activity stops
• difficulty moving your foot
• a muscle bulge big enough to see

When should I see my doctor?

If you’re experiencing the symptoms listed above, you should see your doctor.

How is compartment syndrome diagnosed?

Your doctor will talk to you, examine you and measure the pressure inside the compartment.
