摘　　要：目的　了解骨节段性延长转移 (SBTL)对长骨大段骨缺损断端和延长区血循环的影响以及骨修复重建过程。　方法　通过建立 18只山羊胫骨 35 %以上长骨干缺损模型 ,采用SBTL方法进行实验性治疗 ,并行X线、墨汁灌注透明切片及组织学观察。　结果　骨节段延长转移的长骨骨缺损断端血循环丰富 ,骨愈合良好 ,延长区血供丰富 ,骨修复迅速。Objective To study the effects of segmental bone transport by lengthening(SBTL)on the blood circulation and the repair-reconstruction of the lengthened area and the large segmental bone defect(LSBD). Methods Segmental bone defects of 37.72% of the original length on average were treated by SBTL in 18 mature goats. The effect was observed with X-ray and histomorphology. Results Ample blood circulation and sound bone union were observed in the lengthening area and the bony defect ends. The limb discrepancy was corrected completely. No disorder of nerve was found. Conclusions Devoid of bone grafting, SBTL offers a new alternative to the treatment of LSBD.
