摘要
取自身对照方法对18条成年雄性家犬36侧股骨头颈部,分为两组。分别制成陈旧性股骨颈骨折和股骨头缺血性坏死模型,2周后进行吻合血管腓骨移植。术后分别进行X线片、病理组织学、电镜、99锝一亚甲基二膦酸盐骨扫描和四环素荧光标记等观察。实验结果表明:吻合血管腓骨移植为损伤股骨头提供了新的血供系统;坚硬的游离腓骨和金属内固定同时插入股骨头颈部,术后腓骨在骨折区形成骨桥,不仅能消除剪力,而且防止骨折断端旋转移位;移植腓骨骨膜也参与了股骨头缺血性坏死的修复过程。
The authors adopted an auto control experimental research on 18. male adult dogs with 36 sides of femoral heads and necks which were
divided into two groups. They were separately made models of-old fracture of femoral neck and avascular necrosis of femoral head . Two weeks
later,The free fibula with microvascular anastomosis was transplanted. All experimental dogs were examined with X-ray,pathohistology,electron microscopy ,99mTC MDP scanning and Tetracycling labeling after operation.
The experiment showed that the free fibular graft with microvascular anastomosis could provided a new system of vascular supply to the injured femoral head. After the operation, In the fracture area the fibula formed a bone-bridge which not only diminished the stress force but also prevented rotation displacement of the bone fracture. The periosteum of the transplanted fibula also took part in the repair course of avascular necrosis of femoral head .
