Vascularized and conventional autogenous rib grafts were used to reconstruct 6-cm ulnar defects in the forelegs of the nine dogs. Each dog served as its own control. Biomechanical torsional testing of the grafted ulnas showed that vascularized grafts were 234 percent stronger than the conventional grafts. Bone toughness (energy absorbed) was 483 percent greater in the vascularized grafts, and elastic modulus and proportional limits were 263 and 246 percent greater, respectively. We conclude that vascularized bone grafts are significantly stronger than conventional autogenous bone grafts after 3 months of healing in the dog ulna model.
采用带血管蒂和传统自体肋骨移植,对9只犬前肢6厘米尺骨缺损进行修复。每只犬均作为自身对照。对移植后的尺骨进行生物力学扭转测试,结果显示带血管蒂移植骨的强度比传统移植骨高234%。带血管蒂移植骨的骨韧性(吸收能量)比传统移植骨高483%,弹性模量和比例极限分别比传统移植骨高263%和246%。我们得出结论,在犬尺骨模型中愈合3个月后,带血管蒂骨移植比传统自体骨移植明显更强。
