摘要 目的探讨治疗股骨远端粉碎性骨折的新方法。方法应用10件成人鲜尸股骨,造成股骨远端髁间、髁上粉碎性骨折,内侧采用聚乙烯板、外侧采用钢板双向固定,分别作压缩、弯曲、扭转等生物力学实验研究。另取10件标本进行单向外侧钢板固定作为对照。结果双向固定组抗弯曲、扭转能力显著增强(P<0.01),抗压缩能力也较单侧固定组强(P<0.05)。结论双向固定治疗股骨远端粉碎性骨折有明显的应用价值。 Objective To explorethenewtreatmentapproachfor comminutedfracturesof thedistalfemur.Methods Supra-andintercondylarcomminutedfractureswereinducedinthefemursof20freshadultcadavers,10of whichreceivedfixation withlateralsteelplatesandmedialpolyethylenesplateswhiletherestwithsingleplateinthelateralonly.Biomechanicaltests of bending,torsionandcompressionwereperformed.Results Biomechanicaltestdemonstratedthatdouble-platefixation providedbetterresistanceto compression(P<0.05)as wellas bendingandtorsion(P<0.01)thansingle-platefixationdid.Conclusion Double-platefixationis effectiveandmay havepotentialclinicalvaluein treatingcomminutedfracturesof the distalfemur.
