2、同时问点(2,6和12周)采用大体观察、x片影像学、组织学等方法观察和评估CSC植入后在椎体松质骨内的成骨和降解情况。结果术后兔进食,活动正常,标本周围软组织无炎症反应。CSC在植入2周见少量新生骨,6周植入物部分吸收,见大量新生骨,l2周植人物全部吸收,并有编织骨形成,成骨量明显高于对照组(P<0.05)。结论可注射性硫酸钙有良好的生物相容性,植入椎体后成骨作用明显,新生骨与植人材料的吸收降解同步.是一种良好的骨移植材料。关键词:可注射性;硫酸钙;兔;成骨I生能中图法分类号:R687.34文献标识码:A文章编号:1009-88ix(2ol1)03-0404.03BoneFormationof
