neglected, untreated and delayed femur neck fractures are commonly encountered and the treatment dilemma arises especially when the patient is physiologically young and osteosynthesis is the preferred option. controversy exists in the current literature as the various head salvage surgeries like valgus subtrochanteric osteotomy, non-vascularized fibular bone grafting, muscle pedicle bone grafti...

This paper deals with the development of a medical support model that can be used as prototype to study anatomy femur and for biomechanical research experimentation related bone plates. CT scan data are converted into 3D using MIMICS software imported finite-element analysis. The materials selected fabrication were PEEK CF (infused chopped carbon fibre). was analysed ANSYS® WORKBENCH® 2021 R2 d...

background: the aim of the present study was to evaluate the relationship between the bone density of various regions of jaws and skeletal bones. materials and methods: a total of 110 patients with a mean age of 55.01 ± 10.77 years were selected for the purpose of the present descriptive study. dual x-ray energy absorptiometry (dxa) was carried out to determine bone mineral density (bmd) of the...

ABSTRACT: Relationship between bone fluoride content, pathological change in bone of aborted fetuses and maternal fluoride level was studied in 46 pregnant women and their inducedly-aborted fetuses. Results showed fluoride content in fetal femur averaged 368.2 micrograms(ug)/g, and 41.4% of the bone with pathological change. Fluoride levels in maternal urine and amniotic fluid and fluoride cont...

background: fluoride (f−) is a trace element that is incorporated into bone mineral during bone formation. this study assessed the effect of increasing fluoride doses on the bone formation and microarchitecture on the femur of rats by histological, and histometrical methods. materials and methods: a total of 16 rats was divided into one group of control and three groups of animals that received...

  This is the early results of 20 cases of massive osteoarticular allograft performed for reconstruction of lower limb s after resection of bone tumors. These cases include 7 distal femur and hemiarticular ,6 proximal tibio and hemiarticular, 3 total knee joints and 4 proximal femur with total hip replacement. Bone allografts were taken at steril condition from early postmortum cadavers and st...

Introduction: The human anthropometric characteristics are surveyed in anthropology. Anthropology is used in archeology, rehabilitation and legal medicine. The purpose of this study was to determine femur which has a special place in the science of anthropometry. Methods: To measure the femur, both direct and indirect methods was used. The direct method of measuring the 113 femur in dissection...

The natural distribution of stress in the femur is altered when total hip arthroplasty (THA) performed. In fact, a stem inserted inside femur, there variation due to difference rigidity between material with which made and femur. This generates phenomenon shielding. aim this study design an optimized prosthesis that guarantees excellent rotational stability reduced Methods: Through finite eleme...
