| Abstract: | We measured the levels of biochemical markers of bone formation and bone resorption in hip fracture patients preoperatively and after 6 and 12 months. Bone densitometry was done with quantitative computer tomography (QCT), dual-energy X-ray absorptiometry (DXA) and heel ultrasound. After 6 months, the biochemical markers of bone formation and bone resorption had increased. The levels remained high after 1 year and no change occurred between 6 and 12 months. We found no correlations between biochemical bone markers and bone density/ stiffness on admission and change in bone mineral density (BMD) during the first postoperative year, despite the changes in bone markers and bone density. In our opinion, biochemical bone markers can not be used to predict bone loss in the individual patient after a hip fracture. |
