Abstract

Comparative assessment of software HAS for Hologic densitometer was performed in two groups of osteoporotic patients (mean age 60.4 years) with and without proximal femur fractures. The area of cross-section, cross-section moment of inertia, axial moment of section resistance, cortical bone thickness and coefficient of bending were assessed in three zones of the femur (narrow part of the neck, intertrochanteric and diaphyseal zones). Results of linear discriminant analysis showed that totality of 9 out of 15 geometric parameters assessed by that program enabled with 100% probability to differentiate patients with and without fractures and gave the background to introduce that method into clinical practice for timely detection of patients with high risk of proximal femur fracture.
