Simultaneous bilateral femoral neck fractures are extremely rare and associated with various conditions. Up to now Most cases had correlations with major trauma, repetitive minor trauma, seizure, parathyroid or renal dysfunction, anti-epileptic medications, seizure, etc. A 28-year-old addict man referred to us with a 10-year history of narcotic drug abuse and history of 8 months bilateral groin...

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...

Computational studies have recently gained significant interest in engineering applications for the virtual monitoring of bone pathologies such as osteoporosis and fracture healing. Several authors have investigated numerically the role of quantitative ultrasound as a diagnostic and monitoring tool of the fracture healing process since ultrasonic techniques are non-invasive and non-ionizing mea...

Most long-bone fractures heal through indirect or secondary fracture healing, a complex process in which endochondral ossification is an essential part and bone is regenerated by tissue differentiation. This process is sensitive to the mechanical environment, and several authors have proposed mechano-regulation algorithms to describe it using strain, pore pressure and/or interstitial fluid velo...

Background: Osteoporosis and hyperkyphosis could impose a considerable financial and therapeutic burden on the affected society. Thus, new strategies to prevent or manage such complications are of significant importance. Here we evaluate the effect of ‘Dynamic Hyperextension Brace’ (DHB) on bone density, and hyperkyphosis correction. Methods:Sixty postmenopausal women were randomly assigned to ...

Bisphosphonates are highly effective agents for reducing osteoporotic fractures in women and men, decreasing fracture incidence at the hip and spine up to 50%. In a small subset of patients, however, these agents have recently been associated with 'atypical femoral fractures' (AFFs) in the subtrochanteric region or the diaphysis. These fractures have several atypical characteristics, including ...

Osteoporosis currently affects over twelve million Americans with another forty million affected by osteopenia or low bone mass [1]. Low bone mineral density has long been known to increase the risk of fragility fracture defined as “any fracture caused by injury that would be insufficient to fracture a normal bone”, typically occurring in the hip, vertebrae, wrist, and proximal humerus [2]. The...
