摘　　要：采用髓内皮质骨移植和松质骨充填，互锁双钢板固定治疗长骨干节段性骨缺损，观察移植骨和宿主骨的修复愈合过程和转归特点。结果显示：１２～２４周时植骨愈合良好，１２周时髓内植骨两端已与宿主骨愈合，２４周时髓内植骨两端呈松质骨化，充填的松质骨部分已改建为板层骨，骨缺损已大部分修复。新骨的形成是以哈氏系统为中心向外呈同心圆扩展，不同时期的新骨形成清晰可见。本法不仅可以恢复骨结构的完整性、固定可靠，而且具有良好的生物诱导作用，可满足早期活动的需要，减少或避免并发症。Observations were made on the repairing healing courses and transformation between graft bone and host bone in the treatment of segmental defects of long bones by IDP with intramedullary cortical bone graft and packed iliac chips.It was showed that the bone defect repaired in 12 to 24 weeks.The intramedullary graft united with fragment ends in 12th week.The bone defect repaired mostly in 12th week with cancellous ossification at two ends of graft and lamellar of packed iliac chips.The way of new bone formation is a process from inner to outer layer with Haversian system as its circle center.The newly formed bone can be seen clarely at different stages.IDP used in the treatment of segmental defects of diaphysis of long bones with intramedullary cortical bonegraft and packed iliac chips,not only can maintain the intact of bone structure and firm immobilization,but also has the function of biological induction.Patients treated with IDTP can be ambulatory early with few complications.(Original aritcle on page 94)
