It has been hypothesized that the abnormal stress and strain energy distributions in an impinged femur can result in an unusual rate of bone remodelling which ultimately can cause cartilage destruction and oseoarthritis. Finite element models were created to simulate the healthy control case and the abnormal impingement case. Implementing inverse dynamics data onto the finite element models, it was found that stress and strain energy concentrated at the antero-superior portion of the femoral head-neck junction. IN this comparative study, the abnormal geometry demonstrated a higher stress concentration by 21.0% and a higher strain energy density by 29.2% – further suggesting higher prescence of mechanical stimuli.
