Acute Compartment Syndrome of the Lower Extremity Secondary to Noncontact Injury

We retrospectively reviewed the cases of three patients with injuries similar to the mechanism of an ankle sprain which resulted in compartment syndrome of the lower extremity. All three patients presented with sharp, proximal, anterolateral pain in the leg after an indirect, twisting injury. None of the injuries involved direct contact. Two of the three athletes initially presented to local hospitals, where the injury was misdiagnosed as an ankle sprain. The mechanism appears to be a muscle strain or tear with resultant hemorrhage in the compartment. All three patients returned to high-level athletics after prolonged recovery periods.
