[Exercise-induced acute bilateral isolated anterolateral compartment syndrome of the leg: a case report of a rare condition]. / Syndrome de loge d'effort de jambe antéro-latéral isolé, aigu et bilatéral. Une entité clinique rare: à propos d'un cas.

Acute compartment syndrome of the leg is generally a consequence of trauma. Exercise-induced acute compartment syndrome of the leg is an exceptional clinical entity observed in the context of a chronic compartment syndrome or as an isolated acute syndrome subsequent to an intense effort. Our patient was a young athlete with no history of exercise-induced leg pain. Following a soccer game, he developed an acute leg syndrome involving the anterolateral compartment of both legs. The diagnosis was not suggested by the patient's history (no notion of chronic compartment syndrome) nor the natural history of the condition but was retained on the basis of the clinical presentation and course then confirmed by intramuscular pressure measurements. Emergency treatment by fasciotomy under general anesthesia in the operating room led to cure with no sequela. The fasciotomy was closed on day 9 with simple skin sutures. Surgeons should be aware that acute exercise-induced compartment syndrome (with the risk of severe functional consequences) may be the cause of unexplained intense leg pain. The diagnosis is established on the basis of clinical findings and measurement of intramuscular pressures. Pain is the cardinal sign, sometimes associated with sensorial deficit. The compartment is hard and painful at palpation. Passive stretching exacerbates the pain. Compartment pressure is required for certain diagnosis, most Authors accepting > 30mmHg as a positive test. Emergency fasciotomy is required.
