Biochemical bone markers and bone density in hip fracture patients - Weak correlation in 106 women

Biochemical markers of bone formation and bone resorption were measured pre operatively, within 18 hours after a hip fracture (n 106) and bone mineral density (BMD) was measured with quantitative computer tomography (QCT), dua l-energy x-ray absorptiometry (DXA) and heel ultrasound in 63 hip fracture patients. Patients with pertrochanteric fractures had more osteoporosis in all measur ements than patients with femoral neck fractures, We found no differences i n biochemical markers of bone formation or bone resorption in patients with femoral neck fractures and in those with pertrochanteric fractures. Correl ations between biochemical bone markers and bone density, bone mass and sti ffness on admission were weak.
