Compartment syndrome with foot ischemia after inversion injury of the ankle

This article reports the case of a 17-year-old girl who presented with compartment syndrome and acute ischemia of the foot after a minor ankle sprain. The suspected cause of compartment syndrome was secondary emergence of swelling and palsy of the foot. The posterior tibial and dorsalis pedis pulses were nonpalpable. The syndrome was confirmed by measurement of the pressures in the compartments of the foot, which were >30 mm Hg. Foot fasciotomy was successfully performed by using a three-incision technique. In contrast with previous case reports, no bone or vessel lesion was detected to explain the onset of a compartment syndrome. To our knowledge, this is the first case report compartment syndrome of the foot after an isolated minor ankle injury. Physicians should be aware of the possibility of compartment syndrome of the foot emerging irrespective of the severity of the initial trauma.
