Anterior and posterior motor compartment syndrome have been observed in four burn patients. Recognition was difficult because of multiple concurrent problems, including burns and thrombophlebitis of the involved extremities. Early fasciotomy was performed in one case, with good return of function. Muscle necrosis occurred in two patients in whom diagnosis was delayed. Electromyography is of benefit in confirming the diagnosis and providing follow-up management. It is important to maintain a high index of suspicion of this syndrome in patients with overlying burns.
