Evaluation of quantitative CT vertebral bone mineral density measurement and the Singh index in elderly females with hip fractures--a case control study.
This study aims to evaluate the ability of quantitative computed tomography (QCT) bone mineral density (BMD) measurement of vertebral bodies to predict risk of hip fracture. We also examine the predictive value of the radiographic Singh index and its relationship to the vertebral BMD. The vertebral BMD (using a QCT protocol) and radiographic Singh index were evaluated in 86 white females who had sustained a hip fracture after minor trauma. 86 age-matched female controls were also studied. All patients were post-menopausal, the age range was 52-95 years. BMD values were found to be low in both the study group and controls; there was no statistically significant difference between the groups. A low Singh index did not correlate with hip fracture, nor did it correlate with low vertebral BMD measurement. We conclude that vertebral BMD and radiographic Singh index are not reliable predictors of hip fracture in the elderly female.
