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.
Surgery can cause bleeding, infection, or allergic reaction to anesthesia. The muscle and nerves may not return to normal after recovery.
A scar may appear where the skin was left open following surgery.
Any new or worsening symptoms should be reported to the healthcare provider.
