CONTEXT It is believed that about 25% of menopausal women in the USA will exhibit some kind of fracture as a consequence of osteoporosis. Fractures of the proximal femur are associated with a greater number of deaths and disabilities and higher medical expenses than all the other osteoporotic fractures together. OBJECTIVE To study the clinical and epidemiological features of patients with pro...

Studying stress and strain trends in the femur and recognizing femur failure mechanism is very important for preventing hip fracture in the elderly. The aim of this study was to identify high stress and strain regions in the femur during normal walking and falling to find the mechanical behavior and failure mechanism of the femur. We developed a finite element model of the femur from the subjec...

PURPOSE We aim to retrospectively evaluate patients with non-ossifying fibroma (NOF) of the distal femur by radiographs, CT and MRI, and to provide a theory describing the reasoning for the distal femur NOF's location and aetiology. METHODS Charts of patients with NOFs between 2003 and 2014 were retrospectively reviewed. Inclusion criteria encompassed a diagnosis of NOF of the distal femur by...

BACKGROUND Ethnic dimorphism in the distal femur has never been studied in a three-dimensional analysis focused on shape instead of size. Yet, this dimorphism has direct implications in orthopedic surgery and in anthropology. The goal of this study was to show that differences in distal femur shape related to ethnic dimorphism could be identified, visualized, and quantified using 3D geometric m...

BACKGROUND The non-union within the femur with shortening of the limb as a consequence of trauma is an indication to choose external stabilisation as a method of treatment for that reason, that healing of the bone and surrounded soft tissues is disordered. MATERIALS AND METHODS Authors discuss the results of treatment of 16 patients with post-traumatic bone defect and pseudarthroses with femu...

BACKGROUND The femur has a complex shape with marked individual differences. The aim of our study was to investigate the anatomy of the femur in normal subjects using computed tomography imaging with the aim of building a digital database of human femoral anatomy. MATERIAL AND METHODS We studied age- and sex-related variation in the shape of the femur in 169 normal subjects (80 men and 89 wom...

INTRODUCTION In the normal hip, stress is distributed over the entire crossection of the femur. Bending and axial compression are the major modes of loading. Following THA, the stress in the bone is significantly different mainly due to the manner in which the load is transferred to the femur (Huiskes, 1990, Huiskes, 1995). In this case, the load is primarily transferred through shear across th...
