86例胫骨缓慢牵伸延长治疗下肢短缩

86 Cases of Shortened Legs by Slowly Lengthen the Tibia With Pulling

目的 探讨胫骨缓慢牵伸延长的方法以及骨膜在骨延长中的作用。方法 胫骨骨骺延长是分离骨骺的方法。胫骨干骺端是剥离骨膜后采用不同的截骨方式。结果 骨骺分离实际延长 3～ 5cm ,干骺端截骨实际延长 3～ 10cm。本组 86例无一例神经血管损伤 ,骨的愈合达 10 0 %。结论 截骨方式不同在骨延长中无明显差异 ,而骨膜的完整性及剥离骨膜的范围对骨延长的影响 ,更值得重视。

Objective To search the method of slowly lengthening the tibia by pulling, and roles of periosteum in the lengthening of bones.Methods Separating the epiphysis by lengthening the epiphysis of the tibia.Result 3 to 5cm was lengthened by separating epiphysis, while 3 to 10cm was lengthened in the main end of epiphysis by cutting bone.Conclusions Different ways of cutting bone don't have any obvious differences in lengthening bone,the surgeon should pay much more attention to the integrity of periosteum and how range of separation periosteum will produce an effect on the lengthening of bones.
