Morphometric study of proximal femur in fractured and non-fractured post menopausal women
Objective: This study was conducted to investigate the risk of hip fracture using proximal femoral morphometry in fractured and nonfractured postmenopausal women.
Methods: We conducted an observational cross-sectional study with 138 postmenopausal women (49 fractured and 89 nonfractured). The hip axis length (HAL), femoral neck axis length (FNAL), acetabular width (AW), femoral head width (FHW), femoral shaft width (FSW), and femoral neck shaftÂ angle (FNSA) were measured in all cases by dual energy X-ray absorptiometry. We also studied the correlation between body mass index (BMI) withÂ all the parameters in fractured and control groups.
Results:The mean age, height, weight, and BMI were 61.24Â±3.23, 163.94Â±7.84 cm, 71.88Â±9.14 kg, and 26.72Â±2.78 kg/mÂ², respectively, in fracturedÂ patients. In nonfractured patients the values were 59.73Â±5.32, 161.73Â±4.25 cm, 69.54Â±6.25 kg, and 26.74Â±2.23 kg/mÂ² respectively. The mean HAL,Â FNAL, AW, FHW, FSW, and FNSA were 130.5Â±3.18 mm, 111.26Â±3.64 mm, 18.2Â±1.91 mm, 53.46Â±1.51 mm, 37.45Â±1.82 mm, and 132.76Â±3.15 degree in case group and 130.84Â±4.74 mm, 112.48Â±4.08 mm, 17.57Â±2.32 mm, 53.4Â±1.86 mm, 35.29Â±1.82 mm, and 128.76Â±3.6Â° in control group, respectively.
Conclusion: The femoral parameters such as HAL, FNAL, AW, and FHW do not indicate any correlation between fractured and control groups, whereasÂ FSW and FNSA were significantly higher in case group. The FNSA was having significant negative correlation with BMI in fractured group while thatÂ was having a significant positive correlation in the nonfractured group. This observation will be helpful in exploration of its clinical significance inÂ proximal femoral fracture.
