摘　　要：目的：探讨隐匿性骨折ＭＲＩ诊断的价值。方法：３２例患者，男２１例，女１１例。平均年龄３４岁（年龄范围８～６６岁）。患者均有明确外伤史，Ｘ线片显示骨质正常，患者有不能缓解的膝关节疼痛。结果：３２例患者骨折发生在股骨１８处，胫骨２１处，腓骨小头１处，髌骨２处。７例患者股骨、胫骨同时受累；３例患者股骨内、外髁同时被累及。６例患者同时有前交义韧带损伤；１例有后交义韧带撕裂；１例有髌下脂肪垫损伤。结论：ＭＲＩ检查可以发现膝关节急性创伤患者Ｘ线平片表现正常而确有骨折存在的隐匿性骨折。诊断准确并可以发现其它合并损伤。Objective:To study the diagnostic value of the occult fracturcs of knee by MRI.Methods:Thirty-two patients were studied,there were 21 man and 11 woman.The ages of the patients ranged from 8～66 years with average of 34 years.All of the cases had clear traumatic history and pain in diseased knee,the plain radiographs of knee were all normal.Results:There were 18 fractures in the femurs,21 in the tibiae,1 in the caput fibulae and 2 fractures in the patellas.Both femur and tibia involved in 7 cases,both condyles of femun involied in 3.There were ACL injury in 6,PCL and infrapatellar fat injury in 1 respectly.Conclusion:MR examination can detect the occult fracture of knee which shows normal on plain radiography after acute trauma,The diagnosis of the occult fracture is correct and can discover the associated injuries in most instances by MRI.
