摘　　要：为评价胫骨内侧骨瓣截取后对供区骨骼生物力学性质的影响。选取经防腐固定的成人胫骨36根,随机分为三组,分别在胫骨内侧从内踝上5.0cm处起切取长度为10cm的骨瓣,厚度分别为一个骨皮质(A组)、胫骨横截面的1/3(B组)和胫骨横截面的1/2(C组),分别对其进行抗压、三点抗弯曲及抗扭转能力生物力学测试。结果显示,三组造模前后在抗压、三点抗弯曲及抗扭转能力上均有显著性差异(P<0.05);造模后,三组间在抗压、三点抗弯曲及抗扭转能力方面均无显著性差异(P>0.05)。表明应用胫骨皮瓣修复骨缺损,切取胫骨瓣范围在一个皮质至胫骨横截面的1/2之间具有可行性。To estimate the influence on ossature vitodynamics of donor site postoperation of tibia skeletal flap being cut. 36 cases of adult tibias, fixed by corrosion protection, were randomly divided into three groups, group A, group B and group C. All of them 10-cm-length skeletal flaps were fetched on the wall of tibia (5 cm above the inner malleolus ) respectively, and thickness of three groups were a cortical bone, 1/3 and 1/2 of tibia transverse sections. Items of Anti-pressure, bent on three points and torquing ability of them were examined. It showed in three groups all had significant difference on Anti-pressure, bent on three points and torquing ability ante-and hypo-making models(P<0.05), and there had no significant difference of them post-making models (P>0.05). It indicated that the ranges of tibia skeletal flap cut from a cortical bone to 1/2 of tibia transverse section was feasible, used for bone defect recovery.
