Classification of diaphysis based on the mechanical response of femur bone

Abstract

This work deal with the biomechanical analysis of the Captum Collum Diaphysis (CCD) femur bone. The femur is the largest bone in the upper leg. The angle between femur neck and femur shaft of the femora is a parameter in determining the CCD or FSA angle. 126 ° is the usual angle for a healthy adult and variation in this angle leads to the CCD. This angle in the femur bone helps in determining the knock knee and bow leggedness orthopaedic disease. This angle impacts on the distribution of stress and deflection in the femur bone during the daily activities. Computational Multi-Scale analysis has been done for homogenized properties of femur bone. A Numerical simulation has been made for the biomechanical analysis of CCD femur bone using Finite Element Method. There is significant impact of stress distribution and deflection over the femur bone in case of change in optimum CCD angle (coxa norma) and also leads to change the natural frequency of the bone. Predicted results shows the above mentioned disease behaviour over the healthy bone. The study of these deformity and their results are of clinical importance in musculoseketal behaviour of the human femur bone.

The impacts on the locomotor system triggered by the coxa valga and coxa vara pathologies: an integrative review

“…Por outro lado, na coxa vara pode ocorrer o "geno valgo", que consiste nos joelhos voltados para a face mediana e mais próximos um do outro. Indivíduos com geno varo podem ter sobrecarga da parte interna do joelho e no geno valgo podem ter sobrecarga da porção externa, propiciando lesões em estruturas ósseas, musculares e ligamentares, além do risco de osteoartrite de joelho (Gautam & Rao, 2019).…”
