Based on the thermo elasticity, using finite element method to analyze the stress of femur-prosthesis system when the hip joint has been replaced, a reference for the selection of prosthesis material is presented after discussing the thermo physical property of material which has an effect on the stress of femur-prosthesis system. We assume that prosthesis, bone cement and femur are linear elas...

The authors examined the associations of maternal smoking in pregnancy with various fetal growth characteristics among 7,098 pregnant women participating in the Generation R Study (2002-2006), a population-based prospective cohort study of pregnant women and their children in Rotterdam, the Netherlands. Maternal smoking was assessed by questionnaires administered in early, mid-, and late pregna...

Histomorphometric analyses of the mandible and femur were performed in senescence-accelerated mice (SAM) using SAMP6 as a senile osteoporosis (OP) model, SAMP8 as a temporomandibular joint osteoarthritis (TMJOA) model, and SAMR1 as control. Thirty-six male mice at 2 or 4 months of age (6 for each strain and age) were used. The cortical thickness index (CTI), bone area (B.Ar/T.Ar), trabecular wi...

Femur parameters are key prerequisites for scientifically designing anatomical plates. Meanwhile, individual differences in femurs present a challenge to design well-fitting anatomical plates. Therefore, to design anatomical plates more scientifically, analyses of femur parameters with statistical methods were performed in this study. The specific steps were as follows. First, taking eight anat...

The Birmingham mid head resection (BMHR) arthroplasty can be used as an alternative to conventional stemmed total hip arthroplasty in young patients unsuitable for hip resurfacing. This study investigated the effect of stem size on femoral neck fracture in the BMHR. Sawbones composite femurs were randomly allocated to one of the following groups: (1) unprepared femur with no prosthesis, (2) fem...

background:  distal femur wedge osteotomies for varus or valgus alignment of the lower extremity could be done in either uniplanar or biplanar fashion.:union: time and stability of the osteotomy site has been considered important in this anatomic region. in this study, clinical and radiographic findings of biplane distal femur osteotomy were reported. methods: clinical, functional, and radiolog...

background: the principal aim of this study was therefore to investigate association between family history of osteo porotic hip fracture, bmd and femur geometry in bushehr city in south of iran. methods: in this cross-sectional study, data were obtained from iranian multi-center osteoporosis study (imos) in bushehr. healthy men and women aged 50 to 75 years were selected based on randomized cl...

OBJECTIVE The aim of this study was to assess the incidence and the effectiveness of treatment of fat embolism in patients with hip and long bone fractures (femur and tibia) in Albania. METHODS 229 patients (68% men) with combined hip and long bone fractures (femur and tibia) hospitalized at the Orthopedics-Traumatology Services of the University Center "Mother Teresa" during 2004-2006 were i...

OBJECTIVE The objectives of this study were to determine the incidence of femur fractures in Colorado children, to assess underlying causes, to determine the prevalence and predictors of associated injuries, and to identify potentially modifiable risk factors. METHODS The study population included all Colorado residents who were aged 0 to 17 years at the time of injury between January 1, 1998...
