Objective: To evaluate the differences between postmenopausal women with previous medial or lateral hip fracture in terms of BMD and bone geometry. Material and Methods: We included all consecutive postmenopausal women with a previous proximal femur fracture, aged more than 60 years, referring to our outpatient clinic from September 2015. We divided our population into 2 groups, according to the site of femoral fracture: medial or lateral. We performed a hip structural analysis (HSA) from contralateral hip DXA images to measure the following parameters: hip axis length (HAL), femoral strength index (FSI), cross-sectional moment of inertia (CSMI), cross-sectional area (CSA), section modulus (Z), and buckling ratio (BR). Results: We evaluated 28 postmenopausal women, mean aged 75.57 ± 6.99 years, with a mean BMI of 25.49 ± 3.05 kg/m2. Of these, 9 had a previous medial fracture (mean aged 74.67 ± 6.61) and 19 had a previous lateral fracture (mean aged 76.00 ± 7.30). There were statistically significant differences between groups in lumbar spine BMD (0.926 ± 0.204 g/cm2 vs. 1.107 ± 0.171; p = 0.010) and femoral neck BMD (0.652 ± 0.066 g/cm2 vs. 0.730 ± 0.097; p=0.019). However, women with a previous medial hip fracture had a greater HAL than lateral hip fracture group (109.06 ± 9.58 vs. 107.07± 6.00; p = 0.508), although there was not a statistically significant difference. Conclusions: Our results showed that in our population of postmenopausal women the group with a previous lateral hip fracture had a worse BMD and a lower HAL than the group with a previous medial hip fracture.
