Bilateral thigh compartment syndromes from extended sitting with forward bending

Abstract

Alcohol consumption and subsequent sleeping in unusual positions often causes compression neuropathies. In this case, we experienced a unique case of bilateral leg palsy after sleeping in a forward bending position that was photographed by his colleague. We expected that prolonged blockage of the circulation of the femoral arteries resulted in bilateral thigh compartment syndromes (TCSs), leading to sciatic nerve damage. The muscle MRI and needle EMG support this hypothesis. A couple of similar cases have been reported, but the causes of TCS was undetermined due to lack of medical history. This case illustrates that atraumatic compartment syndrome with sciatic nerve palsy can be occurred by prolonged unusual positions.
