MPR及X线测量股骨头颈比的对比研究

MPR and X-ray measurement of the femoral head-neck ratio

目的对比MPR及X线测量股骨头颈比,为临床治疗提供参考。方法 MPR组为150例行髋关节CT检查患者,X线组为同期行骨盆正位片检查的患者,分别测量股骨头最大直径和股骨颈最小直径,并计算头颈比例。结果MPR组的股骨头颈直径比例为1.48±0.17;X线组的股骨头颈直径比例为1.45±0.12。MPR组的股骨头最大直径为(42.98±6.18)mm,X线组的股骨头最大直径为(42.76±3.98)mm。MPR组的股骨颈最小直径为(27.15±6.12)mm,X线组的股骨颈最小直径为(29.16±2.67)mm。结论股骨头颈比例的测量在髋关节撞击综合征的诊断、分型以及异常影像征象的量化方面有一定指导意义。

Objective To measure and compare the femoral head-neck ratio of MPR and X-ray imaging data respectively, and provide reference for clinical treatment. Methods MPR group includes 150 patients underwent CT examination of the hip, X-ray group includes the same patients underwent X-ray examination of the pelvis. We measure the biggest diameter of the femoral head and femoral neck minimum diameter respectively, and calculate the proportion of head and neck. Results MPR group＇s femoral head-neck ratio was 1.48±0.17. X-ray group was 1.45± 0.12. MPR group＇s the largest diameter of the femoral head was 42.98±6.18mm. X-ray group was 42.76±3.98mm. MPR group＇s the smallest diameter of the femoral neck was 27.15± 6.12mm. X-ray group was 29.16±2.67mm. Conclusion Femoral head-neck ratio measurement have certain guiding siguificanee in the diagnosis of hip impingement, classification and quantitative aspects of abnormal imaging signs.
