Ch 30 Musculoskeletal Trauma

A compartment is a section within the body that contains muscles and nerves and is surrounded by fascia. In the human body, limbs such as the arms and legs contain multiple compartments. For example, there are two compartments in the upper arm: anterior and posterior and 4 compartments in the lower leg: anterior, lateral, and posterior (deep and superficial).

Compartment syndrome is increased pressure within one of the body's compartments which contains muscles and nerves. Compartment syndrome most commonly occurs in compartments in the leg or arm. There are two main types of compartment syndrome: acute and chronic.

Acute compartment syndrome occurs after a traumatic injury such as a car crash. The trauma causes a severe high pressure in the compartment which results in insufficient blood supply to muscles and nerves. Acute compartment syndrome is a medical emergency that requires surgery to correct. If untreated, the lack of blood supply leads to permanent muscle and nerve damage and can result in the loss of function of the limb.[1]

Chronic exertional compartment syndrome is an exercise-induced condition in which the pressure in the muscles increases to extreme levels during exercise. The pressure creates a decrease in blood flow to the affected area which leads to a deprivation of oxygen to the muscles.[2] The symptoms are a sensation of extreme tightness in the affected muscles followed by a burning sensation if exercise is continued. Chronic exertional compartment syndrome usually occurs in athletes who participate in repetitive impact sports such as running
