A cortical lesion of the tibial diaphysis in a young patient poses a diagnostic challenge to the clinician. Brown tumors, although not very common, may mimic malignancies on radiographs. Brown tumors are destructive lytic lesions of the bone due to increased osteoclastic activity and fibroblastic proliferation in patients with uncontrolled hyperparathyroidism (HPT). They occur after primary or ...

Objective: The aim of this work was to assess the epidemiological factors of the pseudoarthroses of diaphyseal humeral fractures in order to prevent them and also to assess the results of their treatment by screwed plate associated with an auto-graft. Material and method: This was a retrospective series of 36 aseptic pseudoarthroses of the humeral diaphysis treated by screwed plate, associated ...

As temperature is a common regulator of temperate plant phenology, future increases in global temperatures are likely to cause shifts in the timing of plant phenophases such as flowering and senescence, with potential feedbacks on species interactions and carbon cycling. We used a 3-year field warming study in a temperate grassland to investigate the effects of two levels of warming (þ;1.58C an...

Faithful modeling of the femur accounting for bone distribution and material orthotropic behavior is presented. In this study, a biofidel Finite Element Model (FEM) has been developed from Computerized Tomography (CT) scans using specific combination software’s to correctly represent physiology structural behavior. Proper identification trabecular arrangement in proximal diaphysis enabled defin...
