| 摘 要： | 目的比较颈前路减压后分别植入钛合金螺纹融合支架、异体骨螺纹融合支架和自体髂骨的拔出载荷。方法以人尸体颈椎为标本，颈前路环锯减压后，分别植入钛合金螺纹融合支架、异体骨螺纹融合支架和自体髂骨，测试以上植入物的最大拔出载荷。结果减压后植入钛合金螺纹融合支架、异体骨螺纹融合支架、自体骼骨的最大拔出载荷分别为(114.7±23.3)、(101.5±15.7)、(58.7±8.3)N。结论Cloward术减压后，钛合金螺纹融合支架、异体骨螺纹融合支架拔出载荷均大于植入自体髂骨。

| Abstract: | Objective:To compare the extraction force of different interbody graft fixation at C4 and C5 after cervical decompression with the method of Cloward.Methods:Cervical vertebra was operated at C4 and C5 using orifice through anterior approach.The extraction force was measured after the allograft threaded fusion cage,titanium threaded fusion cage and autograft iliac bone graft were inserted separately into the interbody space.Results:The extraction force of titanium threaded fusion cage,allograft threaded fusion cage and autograft iliac bone graft were 114.0±23.3N and 101.5±15.7N and 58.7±8.3N respectively.Conclusion:Measured with the method of Cloward,the extraction forces of the allograft threaded fusion cage and titanium threaded fusion cage at C4 and C5 are bigger than that of autograft iliac bone graft after cervical decompression. |
