Abstract

In evaluations of a cam deformity on femoroacetabular impingement, the head-neck junction (HNJ) must be accurately assessed. We conducted this study to determine the ability of plain radiography to visualize the end-to-end bone surface of the HNJ. We used six human bone models. Ten examiners evaluated the degree to which attached stainless wire marker at the 1:00, 1:30, and 2:00 radial plane defined in reconstructed computed tomography can be accurately detected on the bone surface on plain radiographies. We employed 13 plain radiographies: the cross-table lateral view, frog-leg lateral view, Espié frog-leg lateral view, false-profile view, modified false-profile view, 30° Dunn view (DV), 45° DV, 60° DV, 90° DV, 30° modified Dunn view (MDV), 45° MDV, 60° MDV, and 90° MDV. Examiners scored the degree to which the radiographic images accurately detected the stainless wire marker on the bone surface of the HNJ on a scale of 1 point (0% match) to 5 points (almost 100% match). The highest score for the 1:00 plane was 4.98 points on the 45° DV. Similarly, the highest scores of the 1:30 and 2:00 planes were 4.98 points for the 45° MDV and 4.68 points for the 90° MDV, respectively. On these bone model studies, the most suitable plain radiography for describing the HNJ at the 1:00, 1:30, and 2:00 planes were both the 45° DV, the 45° MDV, and the 90° MDV, respectively.

x线平片准确描述股骨头颈交界处骨表面的能力:一项使用人骨模型的研究。
在评估股髋臼撞击的凸轮畸形时,头颈连接处(HNJ)必须准确评估。我们进行了这项研究,以确定平片显示HNJ端到端骨表面的能力。我们使用了6个人体骨骼模型。10名检查人员评估了重建计算机断层扫描中定义的1:00、1:30和2:00径向平面上附着的不锈钢丝标记物在x线平片上准确检测骨表面的程度。我们使用了13张x线平片:交叉桌侧位视图、蛙腿侧位视图、espieve蛙腿侧位视图、假侧位视图、修改假侧位视图、30°Dunn视图(DV)、45°DV、60°DV、90°DV、30°修改Dunn视图(MDV)、45°MDV、60°MDV和90°MDV。检查人员对放射图像准确检测HNJ骨表面不锈钢丝标记的程度进行评分,评分范围为1分(0%匹配)至5分(几乎100%匹配)。1:00飞机在45°DV上的最高得分为4.98分。同样,在1点30分和2点的最高分中,45°MDV为4.98分,90°MDV为4.68分。在这些骨模型研究中,在1:00、1:30和2:00平面上描述HNJ最合适的x线平片分别是45°DV、45°MDV和90°MDV。
