In order to decrease the time for treatment in lengthening of limbs, a method has been developed for cortical allografting of the distraction gap. After distraction of a middiaphyseal subperiosteal osteotomy at 1-2 mm per day using a circular external fixator and with an unreamed flexible nail in place, the distraction gap is allografted using a tubular bone segment. In contrast to conventional tubular bone allografting, this graft is slotted. The open end is placed into the most vascular and osteogenic aspect of the bed. This was believed to lead to more rapid consolidation and incorporation of the graft by the host. While some complications occurred, the goals of treatment were achieved in most patients.
为了缩短肢体延长治疗时间,已开发出一种用于皮质同种异体骨移植填充牵张间隙的方法。使用环形外固定器每天以1-2毫米的速度对骨干中段骨膜下截骨进行牵张,并同时置入未扩髓的弹性髓内钉,之后使用管状骨段对牵张间隙进行同种异体骨移植。与传统的管状骨同种异体移植不同,该移植物上开有槽口。开口端放置在骨床血运最丰富和成骨能力最强的部位。据信这会使移植物更快地被宿主骨愈合和整合。虽然出现了一些并发症,但大多数患者实现了治疗目标。
