我们开发了一种仅使用髋关节正位X线片来估计股骨头三维髋臼复盖度的方法。这项技术还允许重新计算中性骨盆倾斜时的覆盖率校正值。在髋臼和股骨头呈球形和一致的情况下，其结果与计算机断层重建的结果一样准确，辐射剂量要小得多，计算所需的时间也要短得多。286名正常受试者的髋关节显示出随着年龄的增长，骨盆的前后覆盖率增加，骨盆后倾角增加，前后覆盖率下降。女性受试者髋臼前部覆盖比例小于男性受试者。受试者站立时骨盆向后倾斜较多，前后复盖率小于仰卧位。
We developed a method for the estimation of three-dimensional acetabular coverage of the femoral head with use of only an anteroposterior radiograph of the hip. This technique also allows recalculation of the corrected value for coverage at neutral pelvic tilt. Provided that the acetabulum and femoral head are spherical and congruent, the results are as accurate as those obtained with computerized tomographic reconstruction, the dose of radiation is much lower, and much less time is required for calculation.The hips of 286 normal subjects showed increases with age in both anterior and posterior coverage and backward tilt of the pelvis, along with a decrease in the anterior-posterior ratio of coverage. The proportion of anterior acetabular coverage in female subjects was smaller than that in male subjects. There was more backward tilt of the pelvis and the anterior-posterior ratio of coverage was smaller when the subjects were standing than when they were supine.
