Multivariate Analysis of Human Adult Femur Length by Various Parameters of Neck of Femur

Abstract

Introduction: Bones forms the main framework of the human body. Bone structure is different in different individuals depending upon race, sex, height, work, nutrition and geographical area. Femur is the bone which is the longest and strongest in human body and shows highest correlation with stature. Aims: This study has been done to determine the relationship of neck measurements with femur length in Maharashtrian population. Methodology: In the present Study, 54 human femur bones were studied for the following parameters using standard procedures. We took femur length (FL), neck length (NL), neck diameter at narrowest site (NDN) and neck diameter at widest site (NDW) in mms. Results: The data was analysed through SPSS software. The descriptive statistics was analysed. Univariate and Multivariate Regression equations were derived to estimate Femur Length from various neck parameters. In univariate analysis, FL was 344.06 + 2.856 NL with R value 0.513 and in multivariate analysis, FL was 209.457+ 0.89 NL + 10.85 NDN -2.98 NDW with R value 0.867. Conclusion: It has been concluded that femur neck length has a positive correlation with total length of femur and femur length can be calculated if measurements of one or more neck parameters are available.
