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.

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
