Abstract：
UNASSIGNED: A plain pelvic radiograph is usually conducted with the lower limbs in internal rotation. This is to correct the anteversion of the femur. However, in the fracture neck of the femur, internal rotation of the fractured limb is avoided, because it would be painful. We examined the effect of correction of anteversion or otherwise on the diameter of the head of the femur using imaging.
UNASSIGNED: This study aimed to determine if there was a significant difference between the femoral head diameter at two different positions, at the normal anatomical position (without correcting the anteversion) and at the corrected anteversion position. It also aimed to document the correlation and the statistical significance between the differences in the size of the diameter at these two different positions with the anteversion angles of the femoral bone.
UNASSIGNED: Two sets of digital photographs of the proximal part of 55 non-sexed, non-paired femoral bones were taken. Images obtained were at two positions: normal anatomical (with anteversion uncorrected) and anteversion corrected positions. The diameters of the head of the femur were documented at these two different positions. The anteversion angles and actual femoral head (AFH) diameters were also measured and documented.
UNASSIGNED: The femoral head diameters at anatomical positions were persistently larger than those measured after the anteversion was corrected, except in three femoral bones (5%) where no differences were observed. The difference in the two measurements was statistically significant to the anteversion angle of the femoral bone. (P = 0.0005). The means of the two sets of measurements were statistically different from each other. Pairwise correlation showed that both were strongly associated with the AFH diameter but the measurements from images with corrected anteversion had a higher value (0.8166) than the measurements from normal anatomical position (0.7526).
UNASSIGNED: The correction of femoral anteversion produced femoral head size measurements that were closer to AFH diameters compared to those without the correction of the femoral anteversion. Femoral anteversion should always be corrected as per protocol.

摘要：
■通常在下肢内部旋转的情况下进行骨盆平片。这是为了纠正股骨的前倾。然而,在股骨颈骨折处,避免了骨折肢体的内部旋转，因为那会很痛苦.我们使用成像检查了前倾矫正或其他方式对股骨头直径的影响。
■这项研究旨在确定在两个不同位置的股骨头直径之间是否存在显着差异，在正常解剖位置（不校正前倾）和校正的前倾位置。它还旨在记录这两个不同位置处的直径大小与股骨的前倾角之间的相关性和统计显著性。
■两组55个非性别的近端部分的数码照片，取非配对股骨。获得的图像位于两个位置：正常解剖位置（前倾未校正）和前倾校正位置。在这两个不同位置记录股骨头的直径。还测量并记录了前倾角和实际股骨头（AFH）直径。
■解剖位置的股骨头直径持续大于前倾矫正后的股骨头直径，除了在三个股骨（5％）没有观察到差异。两种测量值的差异对股骨的前倾角具有统计学意义。（P=0.0005）。两组测量的平均值在统计学上彼此不同。成对相关性表明，两者都与AFH直径密切相关，但是具有校正前倾的图像的测量值（0.8166）比正常解剖位置的测量值高（0.7526）。
■与未校正股骨前倾的测量相比，股骨前倾的校正产生的股骨头尺寸测量值更接近AFH直径。股骨前倾应始终按照方案进行纠正。
