UNLABELLED Patients with extensive malignancies involving the femur often require total femoral replacement when their limbs can be salvaged. Reported series are small and involve heterogeneity of tumours. We present nine patients with osteosarcomas of the femur treated at our institution between 2003 and 2010 with a mean follow-up of 27 (6 to 56) months. Their ages ranged from 9 to 17 (mean 14...

In this paper, a mathematical model is developed to simulate three-dimensional femur bone, taking into account the stress distribution and total displacement during horizontal walking. The principles of continuum mechanics, the field equations governing the displacement and stress fields in the femur bone including the stress equilibrium equations are used in the model. Realistic domain is crea...

Femur fracture is an emerging public health concern in aging societies, owing to the substantially high morbidity and mortality. Because the recent increase in femur fracture incidence in Asian populations is comparable to that in the West, it is necessary to investigate the association between socioeconomic status (SES) and mortality after femur fracture in developed Asian societies.Data were ...

The proximal femur is abnormally shaped in patients with cam-type femoroacetabular impingement (FAI). Impingement may elicit bone remodeling at the proximal femur, causing increases in cortical bone thickness. We used correspondence-based shape modeling to quantify and compare cortical thickness between cam patients and controls for the location of the cam lesion and the proximal femur. Compute...

BACKGROUND This study aimed to identify risk factors for vascular injury in proximal femoral fracture through identifying frequency and distances between femur and femoral arteries with computed tomography angiography and 3-dimensional reconstruction. MATERIAL AND METHODS In a series of 400 participants, based on measurement results regarding the distribution of femoral arteries in the medial f...

OBJECTIVE The aim of this study was to assess bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA) in a group of patients with ankylosing spondylitis (AS) and the factors which have an impact on bone mass. Also, a subgroup of patients not treated with anti-osteoporotic or disease-modifying anti-rheumatic drugs was followed for 24 months to assess potential influencing factors...

BACKGROUND AND PURPOSE Stroke increases the risk of hip/femur fracture, as seen in several studies, although the time course of this increased risk remains unclear. Therefore, our purpose is to evaluate this risk and investigate the time course of any elevated risk. METHODS We conducted a case-control study using the Dutch PHARMO Record Linkage System database. Cases (n=6763) were patients wi...

BACKGROUND Trauma is associated with altered host defense and susceptibility to infection, in part due to cytokine dysregulation and altered T-cell immunity. The gut-associated lymphoid tissue (GALT) provides a defense against infection and contributes to the process of mucosal healing by T-cell activation and cytokine production. OBJECTIVE To determine whether femur fracture induces alterati...

Angular deformities of the distal femur occur in congenital diseases or due to acquired causes, such as malunion after a fracture of the distal femur. Angular deformities of the lower extremities affect the mechanical axis, causing changes in the weight pressure on the articular surface. As a result, angular deformities quicken the progression of osteoarthritis. Therefore, correction of deformi...
