At Risk for Compartment Syndrome
Within the arms and legs, sheets of thick tissue called fascia separate groups of muscles. These sheets of tissue create a confined space, called a compartment. Compartment syndrome occurs when a muscle swells too much within this space. Fascia does not stretch, so it can’t expand. As the muscle swells, it's squeezed tighter and tighter. This slows or stops blood flow in the muscle. It also can injure nerve function. Long-term damage can result. In severe cases, the muscle dies, which may result in amputation.
Swelling that leads to compartment syndrome is most often due to injury. This may be from an accident or other trauma, most often one with a lot of force and damage. Repeated, high-intensity exercise can also sometimes lead to compartment syndrome.
If compartment syndrome is suspected, a healthcare provider can measure the pressure within a compartment. A needle is put into the affected area. The needle is attached to a pressure meter. Pressure readings are then taken. If compartment pressure readings become too high, blood flow and nutrient supply to the tissue may be compromised. If your healthcare provider diagnoses compartment syndrome, emergency surgery is often needed to help relieve it before damage becomes permanent.
Due to your injury, you must watch for symptoms of compartment syndrome (see below). Compartment syndrome is a dangerous condition. It can cause death of the muscle in as little as a few hours. Call your healthcare provider and get treatment right away if you have any of the symptoms listed below.
You may be given medicines for swelling and pain. Follow all instructions for taking these medications.
To help reduce swelling:
Apply an ice pack over the injured area. Do this for 20 minutes every 1 to 2 hours the first day. Continue 3 to 4 times a day until the pain and swelling subside. To make an ice pack, put ice cubes in a plastic bag that seals at the top. Wrap the bag in a clean, thin towel or cloth before using it. Never put ice or an ice pack directly on the skin.
Keep the affected arm or leg raised above the level of your heart. This is most vital during the first 48 hours after an injury. Place pillows under the arm or leg when sitting or lying down and at night while sleeping.
Follow up with your healthcare provider as advised.
Call 911 or get medical care right away if any of these occur:
Pain that gets worse when you stretch, move, or touch the muscle
Pain that does not respond to pain medicines or is getting worse
Pain out of proportion to your injury
Shiny, swollen, pale skin over the injury
Purple foot or hand color past the level of the injury
Decreased feeling in the injured limb
Unusual weakness of the injured muscle
Inability to move the injured muscle
New or worsening numbness or tingling in the injured arm or leg
