平片与MRI在胫骨髁间隆突撕脱性骨折中的诊疗价值

目的评价X线平片与MRI检查对胫骨髁间隆突撕脱性骨折的诊疗价值。方法回顾性分析32例胫骨髁间隆突撕脱性骨折患者X线及MRI影像资料，所有骨折病例均经关节镜证实。X线摄片采用膝关节正侧位，部分加摄斜位；MRI检查采用横断位FSE-T2WI，斜矢状位SE—T1WI、FSE-T2WI、STIR及冠状FSE-T2WI、梯度回波脂肪抑制序列扫描，检查时患者取仰卧位。结果X线平片确诊28例（87．5％），漏诊4例（12．5％）；MR确诊32例（100％）；经X线确诊的患者中，MRI检查均合并周围其他结构的损伤（28／28），其中交叉韧带损伤26例，半月板损伤7例，侧副韧带损伤4例，骨挫伤26例，其他部位的骨折6例；X线漏诊的患者中，合并交叉韧带损伤3例，半月板损伤1例，骨挫伤2例。结论胫骨髁间隆突撕脱性骨折通常合并周围其他结构的损伤，经X线平片确诊的病例可直接行关节镜诊疗：疑似髁问隆突骨折的患者应行MR检查，为临床诊疗提供有效的影像资料。

X-ray and MRI diagnostic value of avulsion fracture in intercondylar eminence of tibia

Objective To evaluate the diagnostic value of X-ray and MRI of avulsion fracture in tibial intercondylar eminence. Methods X-ray and MRI images of 32 patients with avulsion fracture in tibial intercondylar eminence were retrospectively analyzed.All the cases were confirmed by arthroscopy.X-ray examinations were obtained from a standard anteroposterior and lateral views,part of them with oblique views.Axial FSE-T_2WI,sagittal SE-T_1WI,FSE-T_2WI,STIR and coronal FSE-T_2WI,GRE-STIR were examined in MRI examina...
