    • Few studies have examined different bone densitometry techniques to determine male hip fracture risk. We conducted a case-control study of 31 noninstitutionalized men, mean age 77 yr, with a first hip fracture and compared the results with 68 randomly selected age-matched control subjects. The methods used were dual X-ray absorptiometry (DXA) of the proximal femur, quantitative ultrasound (QUS) of the heel and fingers, and radiographic absorptiometry of the fingers. Case patients had significantly lower values (4-17%; p < 0.01) for all methods. The odds ratios for every SD reduction in bone values were 4.8 (95% confidence interval [CI]: 2.3-9.9) for DXA of the femoral neck, 2.2 (95% CI: 1.2-3.9) for QUS of the heel, 2.0 (95% CI: 1.2-3.3) for QUS of the phalanges, and 3.1 (95% CI: 1.5-6.6) for radiographic absorptiometry of the phalanges. The results indicate a strong capability of DXA of the femoral neck to distinguish between men with a first hip fracture and control subjects. Furthermore, ultrasound of the heel and fingers as well as radiographic absorptiometry proved capable of discriminating men with hip fractures from control subjects.

  • DXA of the hip and heel ultrasound but not densitometry of the fingers can discriminate female hip fracture patients from controls : a comparison between four different methods
  • 2001
  • Ingår i: Osteoporosis International. - : Springer Science and Business Media LLC. - 0937-941X .- 1433-2965. ; 12:3, s. 185-191

    • Dual-energy X-ray absorptiometry (DXA) of the proximal femur and in more recent years quantitative ultrasound (QUS) of the heel are the most established methods for assessing hip fracture risk. Measurement of the fingers offers a new approach. We performed DXA of the proximal femur, QUS of the heel and fingers, and radiographic absorptiometry (RA) of the fingers in 87 non-institutionalized women, 65-85 years of age, with a first hip fracture and compared them with 195 randomly selected age-matched controls. Bone mineral density (BMD) of the femoral neck and heel Stiffness Index were significantly lower among cases than among controls (by 15% and 17%, respectively; p < 0.0001), whereas no significant differences were found for finger measurements. When applying the WHO criterion of osteoporosis, 62-98% of the patients were classified as osteoporotic, compared with 19-85% of the controls, depending on method and site. The risks of hip fracture, estimated as odds ratios for every 1 SD reduction in femoral neck BMD, heel Stiffness Index, finger QUS and finger RA, were: 3.6 (95% CI 2.4-5.5), 3.4 (95% CI 2.2-5.0), 1.0 (95% CI 0.7-1.3) and 1.2 (95% CI 0.8-1.6), respectively. Compared with women with normal BMD of the femoral neck, those classified as osteopenic had an odds ratio of hip fracture of 14 (95% CI 2-110), whereas those classified as osteoporotic had an odds ratio of 63 (95% CI 8-501). We conclude that hip DXA and heel QUS have similar capacities to discriminate the risk of a first hip fracture, whereas QUS and RA of the phalanges seem inferior techniques for differentiating female hip fracture patients from controls.
