Calcaneal compartment syndrome after tibial fractures.

Compartment syndrome of the newly discovered calcaneal compartment of the foot is a theoretical possibility following tibial fracture due to the communication with the deep posterior compartment of the calf. Forty-nine patients were reviewed at least 18 months after open or closed tibial shaft fractures treated with tibial nailing in order to determine the prevalence of foot deformities secondary to previously undetected calcaneal or leg compartment syndromes. Ankle movements, foot height, length of feet and degree of clawing of the toes were all measured and compared with the unaffected opposite side. None of the patients complained of any symptoms from their feet and none had any significant foot deformities. Calcaneal compartment syndrome is rare after tibial fracture and routine measurement of calcaneal compartment pressures after such injuries is not indicated.
