INTRODUCTION Posterior hip dislocation of the hip with acetabular fracture is a challenging problem to treat. Such dislocations are associated with avascular necrosis of the femoral head if neglected. Managing such conditions with total hip replacement (THR) is very difficult because of associated altered anatomy. CASE PRESENTATION We hereby report a two-year neglected hip dislocation with as...

BACKGROUND Human parathyroid hormone (PTH) (1-34) or teriparatide (TPTD) is an anabolic agent for osteoporosis. This recombinant protein stimulates positive bone formation balance and bone remodeling. However, when concomitantly used with antiresorptive (AR) agents, previous studies reported conflicting results in their potential additive and synergistic effects on bone metabolism and bone mine...

The skeletal response to short-term exercise training remains poorly described. We thus studied the lower limb skeletal response of 723 Caucasian male army recruits to a 12-wk training regime. Femoral bone volume was assessed using magnetic resonance imaging, bone ultrastructure by quantitative ultrasound (QUS), and bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA) of the ...

Background & Aims: Osteoporosis is the most common metabolic bone disease .In the recent decades due to the increase of population age, the prevalence of osteoporosis has been increased. The most important complication of osteoporosis is bone fracture, especially in the hip. The aim of this study was to evaluate the prevalence of osteoporosis, its mortality rate and direct treatment costs in...

AIM Patients with incipient hip arthrosis may benefit from a relatively new therapeutical approach using resurfacing total hip replacement, but in those with associated osteoporosis, this type of surgical intervention is contraindicated, given the poor quality of osteoporotic bones. We assessed the efficacy of the antiosteoporotic pharmacological therapy to improve bone quality and bone strengt...

We present a method for modeling solid objects undergoing large spatially varying and/or anisotropic strains, and use it to reconstruct human anatomy from medical images. Our novel shape deformation uses plastic strains the finite element successfully model shapes specified by sparse point constraints on boundary of object. extensively compare our standard second-order methods, variational surf...

Bone mineral density (BMD) estimates for the proximal femur using Dual Energy X-ray Absorptiometry (DXA) are currently considered the standard for making a diagnosis of osteoporosis in an individual patient using BMD alone. We have compared BMD results from a commercial Quantitative CT (QCT) BMD analysis system, "CTXA Hip", which provides clinical data for the proximal femur, to results from DX...

INTRODUCTION: Bone conserving designs, such as hip resurfacings, are an alternative treatment option to conventional total hip arthroplasty (THA) in young, active patients. Previous studies have shown that medullary fixation can result in significant proximal bone resorption through stress shielding [1,2], while it has been suggested that hip resurfacing arthroplasty will load the proximal femo...

One of the most successful techniques in restoration of degenerated joint functions is total hip replacement. This surgical approach includes removal of diseased cartilage and bone parts, and replacement by the corresponding joint prostheses. By using metal alloys, high quality plastic and polymer materials, orthopedic surgeons can reconstruct hip fractures, or replace a painful, dysfunctional ...
