【摘要】 目的 探讨股骨颈疝窝的CT表现。方法 回顾性分析450例髋关节CT,分析股骨颈疝窝的发生率及CT表现。结果450例髋关节中,发现股骨颈疝窝24例(31侧),发生率为5.3%,其中男17例,女7例,左侧14例,右侧3例,双侧7例。男女性别组间股骨颈疝窝的发生率有统计学意义(P<0.05),各年龄组间股骨颈疝窝的发生率无统计学意义(P>0.05)。CT表现为股骨颈外上侧皮质下的圆形低密度区,边界清楚,周边有硬化缘。结论 股骨颈疝窝的发生率为5.3%,有典型的CT表现,它的出现提示髋关节撞击综合征可能。更多还原

【Abstract】 Objective To study the CT findings of the herniation pit of the femoral neck.Methods Hips in 450 cases were examined by CT.The incidence and CT findings of the herniation pit of the femoral neck in these 450 cases were analysed.Results Of450 cases,there were 24 cases(31 sides)(5.3%) with the herniation pit of the femoral neck,including 17 men and 7 women.The lesions located in the left joint in 14 cases,the right joint in 3 cases and bilateral joints in 7 cases.There was obvious significant difference in incidence between sexes(P<0.05),but there was no significant differences among age groups.CT showed a round radiolucency with thin clear sclerotic rim.Conclusion The incidence of the herniation pit of the femoral neck is 5.3%,which has a typical CT characteristics,and may indicate the femoroacetabular impingement.更多还原
