Examples of injuries that can cause compartment syndrome include:
Badly bruised muscle.
Car accident.
Crush injury, such as when something falls on you.
Fracture (broken bone).
Sudden return of blood flow after something blocks circulation, such as surgery or loss of consciousness.
Anabolic steroids can also cause compartment syndrome by increasing muscle size too quickly. Other causes include casts or large bandages that are too tight and worn for a while.
