Hip Axis Length

The single best predictor of hip fracture is femoral bone density. But bone density is not the only factor influencing weather or not a fracture will occur. According to engineering principals, strength depends on (1) the mechanical properties of the materials, (2) the objects geometry and shape, and, (3) the loading conditions, in terms of magnitude, rate, and direction, of force applied to the object. If geometry of the hip is related to fracture risk, geometric measurements might be used together with densitometric evaluations for a better assessment of hip fracture risk than might be obtained from just a density measurement alone. Prospective studies show that HAL has demonstrated the ability to predict fractures!¹

Dual Femur

The DualFemur application atomically measures, and averages, both the left and right femora in one measurement sequence. This procedure promises to improve diagnostic accuracy by identifying the femur with the lowest density. An equally important benefit is a 30% decrease in precision error, which improves sensitivity for monitoring response at the femur itself!¹

Upper Neck Region

The upper portion of the femoral neck has been reported to be a sensitive predictor of neck fractures. Studies have demonstrated that femoral fractures are usually initiated in the upper neck region. The thickness and porosity of the bone in the upper neck region is believed to be critical to maintaining femoral strength. The upper neck demonstrates a more rapid age related decline than the standard femoral neck region, suggesting it may provide some advantage for early detection of osteoporosis.¹
