Hip axis length as an independent risk factor for hip fracture independently of femural bone mineral density in Caucasian elderly Brazilian women.
Studies carried out in several countries and in different ethnic groups have suggested that the hip axis length (HAL) may be a risk factor for hip fractures. To evaluate if the HAL is an independent risk factor for hip fractures in elderly Caucasian Brazilian women, this study includes 112 participants sustaining proximal femur osteoporosis. Through HAL and bone mineral density (BMD) measurements, a statistical analysis using a multivaried regression curve was done. HAL was significantly longer in women sustaining a hip fracture than in the control group (99.24 +/- 5.9 mm vs. 96.95 +/- 5.6 mm, P < 0.05). After adjusting the standard HAL deviation for neck and trochanter BMD, OR was 1.43 (IC 95% 0.29 - 1.07; P < 0.08). When HAL was categorized for 97.8 mm (average HAL in all women), OR was 2.24 (IC 95% 1.04 - 4.84; P < 0.05). In conclusion, HAL may be associated with risk of hip fracture regardless of age, weight or BMD of elderly Brazilian Caucasian women.
