摘　　要：目的研究不同脱水程度的同种异体骨螺钉生物力学。方法制作120根同种异体骨螺钉，按脱水程度分为A、B、C、D4组，进行生物力学参数测定。结果A组与对照组相比较生物力学参数无差异；B组与对照组相比较生物力学参数存在差异；C组与对照组相比较生物力学参数存在显著性差异。结论冻干8h（含水量5％）的同种异体骨螺钉，生物力学强度良好。Objective To study the hiomeehanies of different degree of dehydration allogeneie bone screw. Methods According to dehydration degree, 120 allogeneie hone screws were divided into A, B, C, D team,and tested their hiomeehanieal parameters. Results Group A,B ,C and the control group were compared in hiomeehanieal parameters, and group A and the control group were not differences, group B and the control group were differences,group C and the control group were significantly differences. Conclusion Freeze-dried 8 hours（5% water content）of allogeneie bone screws had good hiomeehanieal strength .
