Correlation between Parameters of Calcaneal Quantitative Ultrasound and Hip Structural Analysis in XXXX @entity1 .

@entity3604 @entity1 @entity170 @entity1555 @entity3330
BACKGROUND: Calcaneal quantitative ultrasound (QUS), which is used in the evaluation of @entity170 , is believed to be intimately associated with the characteristics of the proximal femur. However, the specific associations of calcaneal QUS with characteristics of the hip sub-regions remain unclear. DESIGN: A cross-sectional assessment of 53 @entity3604 @entity1 was performed for the skeletal status of the heel and hip. METHODS: We prospectively enrolled 53 female @entity3604 @entity1 with @entity3330 . Calcaneal QUS, dual energy X-ray absorptiometry (DXA), and hip structural analysis (HSA) were performed for each @entity1 . Femoral heads were obtained during the surgery, and principal compressive trabeculae (PCT) were extracted by a three-dimensional printing technique-assisted method. Pearson's correlation between QUS measurement with DXA, HSA-derived parameters and Young's modulus were calculated in order to evaluate the specific association of QUS with the parameters for the hip sub-regions, including the femoral neck, trochanteric and Ward's areas, and the femoral shaft, respectively. RESULTS: Significant correlations were found between estimated @entity1555 (Est. @entity1555 ) and @entity1555 of different sub-regions of proximal femur. However, the correlation coefficient of trochanteric area (r = 0.356, p = 0.009) was higher than that of the neck area (r = 0.297, p = 0.031) and total proximal femur (r = 0.291, p = 0.034). Furthermore, the quantitative ultrasound index (QUI) was significantly correlated with the HSA-derived parameters of the trochanteric area (r value: 0.315-0.356, all p<0.05) as well as with the Young's modulus of PCT from the femoral head (r = 0.589, p<0.001). CONCLUSION: The calcaneal bone had an intimate association with the trochanteric cancellous bone. To a certain extent, the parameters of the calcaneal QUS can reflect the characteristics of the trochanteric area of the proximal hip, although not specifically reflective of those of the femoral neck or shaft.
