Compartment syndromes of the foot after calcaneal fractures

Approximately 10% of calcaneal fractures develop compartment syndromes of the foot, and of these, one half develop clawing of the lesser toes and other foot deformities, including stiffness and neurovascular dysfunction. Tense swelling and severe pain are the hallmarks of an impending compartment syndrome. The diagnosis is confirmed by multistick invasive catheterization, particularly of the calcaneal compartment in the hindfoot. Immediate fasciotomy is recommended to prevent the development of ischemic contracture. It is recommended that open reduction and internal fixation of a calcaneal fracture is performed on a delayed basis, after the fasciotomy wounds are closed.
