When adjusting for femoral neck measurements, what factor may influence the results?

The rotation of the femoral neck is a critical factor when adjusting for femoral neck measurements because it can significantly impact the accuracy of bone density assessments. Proper positioning is essential for obtaining reliable dual-energy x-ray absorptiometry (DEXA) scans, as misalignment due to rotation can lead to incorrect measurements of bone mineral density (BMD). When the femoral neck is rotated, it may appear either denser or less dense than it actually is, which can skew the results and lead to misinterpretation of a patient's bone health.

Other factors, such as a patient's height, age, or previous injuries, can also be relevant in different contexts of bone health assessment, such as determining risk factors or understanding general skeletal changes. However, the specific impact of femoral neck rotation on measurement accuracy makes it a significant concern when analyzing DEXA results for the femoral neck.
