摘　　要：目的:评价Segond骨折的影像学特征并探讨其在膝关节外侧不稳中的临床应用价值。方法:回顾性分析45例临床影像诊断为胫骨平台外缘撕脱骨折(Segond骨折)的病例,分析骨折的特点,包括骨折与膝关节周围韧带、半月板损伤的关系、骨折块的大小、位置,探讨Segond骨折对临床治疗的意义。结果:45例Segond骨折中有41例(91.11%)合并前交叉韧带(ACL)损伤,31例(68.89%)合并前外侧韧带(ALL)损伤,12例(26.67%)合并髂胫束(ITB)损伤。ALL全部附着于骨折块上,ITB附着25例(55.55%)。骨折块体积越大、与Gerdy结节中心的距离越小,ITB附着折块的可能性就越大。结论:Segond骨折常合并ACL损伤、累及ALL、ITB,骨折块越大、距Gerdy结节中心越近累及ITB的可能性就越大,Segond骨折患者应警惕膝关节外侧不稳。Objective:To evaluate the imaging features of the Segond fracture and explore its clinical value in lateral instability of the knee joint.Methods:We retrospectively analyzed 45 cases of the Segond fracture.This involved the analysis of the characteristics of the fracture,including the relationship between the fracture and the ligaments around the knee joint,meniscus injury,and the size and location of the fracture block.Moreover,the significance of the Segond fracture in clinical treatment was discussed.Results:Among 45 cases of the Segond fracture,41(91.11%)had anterior cruciate ligament(ACL)injury,31(68.89%)had anterolateral ligament(ALL)injury,and 12(26.67%)had iliotibial bundle(ITB)injury.The ALL were all attached to the fracture block,and 25 cases(55.55%)were attached to the ITB.The larger the size of the fracture block and the smaller the distance from the center of Gerdy's nodule,the more likely that the fracture block was attached to the ITB.Conclusion:The Segond fracture is often associated with ACL injury,involving the ALL and ITB.The larger the fracture block and the closer to the center of Gerdy's nodule,the greater the possibility of ITB involvement.Therefore,patients with Segond fractures should be alert to lateral instability of the knee joint.
