Atraumatic compartment syndrome of the foot in a 15-year-old female.

Compartment syndrome is a surgical emergency that usually occurs as a sequel to high-energy trauma. We report an uncommon presentation of atraumatic compartment syndrome of the right foot involving the abductor hallucis muscle. A 15-year-old female presented with pain and mild swelling of the right foot after taking part in a school sports activity. Compartment syndrome was diagnosed, >2 months of conservative treatment failed to improve her symptoms, and surgical release and debridement were performed. Our clinical experience demonstrates that compartment syndrome of the foot may occur after mild sports activity in physically inactive children.
