Heterotopic bone is a rare complication of burns. The factors to be considered in its development are the percentage of burn, the location of burn, the length of bed confinement, osteoporosis, superimposed trauma, and genetic predisposition. Characteristically, heterotopic bone develops between one and three months after the acute burn. It may continue to proliferate as long as there are open wounds but it tends to regress once the burn wound has healed. If it has bridged a joint it may be surgically excised after the burn has healed. The more extensive the heterotopic bone the poorer the prognosis for restoration of motion after excision. Prevention of heterotopic bone appears to be linked in part to early mobilization of the patient and recovery from the postburn hypermetabolic and catabolic state.
异位骨是烧伤的一种罕见并发症。其发生需考虑的因素包括烧伤百分比、烧伤部位、卧床时间、骨质疏松、叠加创伤和遗传易感性。典型的情况是，异位骨在急性烧伤后1至3个月内形成。只要有开放性伤口，它可能会持续增生，但一旦烧伤创面愈合，它往往会消退。如果它跨越了关节，可在烧伤愈合后进行手术切除。异位骨越广泛，切除后运动恢复的预后就越差。异位骨的预防似乎部分与患者的早期活动以及从烧伤后的高代谢和分解代谢状态中恢复有关。
