Lower limb compartment syndrome following lumbar discectomy in the knee-chest position.
We report on two cases of compartment syndrome following lumbar discectomy in the knee-chest position. This complication has only been described once since 1953. Seven cases of compartment syndrome following other surgical procedures were found in the literature. Any increases in tissue pressure of a muscle compartment exceeding 35-40 mmHg over a longer period of time can result in this complication for example, too tight cast, space-occupying intrafascial bleeding, or postischemic swelling. The diagnosis is purely clinical and is based on the typical combination of extremely painful edema with rapid onset of sensory loss and subsequent motor deficits. The muscle necrosis leads to myoglobinaemia and myoglobinuria, recognizable by brown urine. The therapy consists of urgent fasciotomy of swollen compartments without skin suture. The prognosis is highly dependent on the time of the surgical decompression: within 6 hours serious deficits are avoidable; after 24 hours irreversible necrosis of muscle occurs. It seems that the possibility of a compartment syndrome is a specific, but a rare risk of a prolonged knee-chest position.
