Accepted: 31.12.2014 In this study, analysed using finite element method (FEM) of biomechanical behaviours of human femur model under the different loads. Geomagic and Soldiworks program were used for 3D model human of femur model, and Ansysworkbench was used for finite element analysis (FEA). Compression, tension, bending and torsional loading were applied to 3D human femur model. Femur bone w...

Using a cluster sampling method, a group of menopausal women from three geographic areas in Tehran were asked to participate in the study. Demographic data was obtained using a questionnaire. Subjects were than referred to perform bone mass densitometry (BMD). The relationship between various variables (i.e. age of menarche, number of years of endogenous estrogen exposure, ... ) with minera...

at neck region called as Trans cervical neck fracture. Third bone shows fracture that happens at intertrochanteric line of femur bone known as Intertrochanteric fracture. The fourth bone shows the fracture that happens at sub trochanteric region named as subtrochanteric fracture, Fracture that happens at greater trochanter region shown in fifth bone is known as fracture at greater trochanter, i...

Tunnel enlargement can appear after anterior cruciate ligament reconstruction. We investigated the influence of the bone block position of a patellar tendon autograft on the tunnel enlargement in the femur and in the tibia from two aspects. On the one hand, we examined the influence of the tunnel position in respect to the ap-diameter. On the other hand, we examined the influence of the bone bl...

Osteoporosis is a disease affecting bones which characterized by decreased bone density; become porous and susceptible to fractures. occurs because of an imbalance during remodeling phase between resorption formation processes. This study aims simulate the effects mechanical stimulations on femoral elasticity limit. It hoped that these stimuli can provide information limits. Initially, we const...

PURPOSE The proximal femur is one of the most common locations for benign bone tumors and tumor like conditions. We describe the clinical outcomes of the surgical treatment of benign lesions of the proximal femur including femoral neck using compression hip screw and synthetic bone graft. METHODS Thirteen patients with benign bone tumors or tumor like conditions of the proximal femur includin...

Biomechanics is a field that combines the disciplines of biology and engineering mechanics and utilizes the tools of physics, mathematics, and engineering to quantitatively describe the properties of biological materials. Finite element modeling has been widely used to describe the mechanical behavior of the long bones which have been created from CT (Computer Tomography) images In this study a...

Osteoporosis is a public health problem characterized by increased fracture risk secondary to low bone mass and microarchitectural deterioration of bone tissue. Almost all fractures of the hip require hospitalization and major surgery. Early diagnosis of osteoporosis plays an important role in preventing osteoporotic fracture. Magnetic resonance imaging (MRI) has been successfully performed to ...

BACKGROUND Revealing data on the role of vitamin D and calcium supplementation in bone health has led some to suggest that vitamin D and calcium treatment could also play a role in protecting bone against microgravity-induced mineral loss. OBJECTIVES The aim of the present study was to investigate the effects of vitamin D and calcium administration on microscopic and densitometric changes of ...
