A finite element model was developed for numerical simulations of nanoindentation tests on cortical bone. The model allows for anisotropic elastic and post-yield behavior of the tissue. The material model for the post-yield behavior was obtained through a suitable linear transformation of the stress tensor components to define the properties of the real anisotropic material in terms of a fictit...

Structural bone allografts have become an alternative in the treatment of limb bone tumours with a chance of limb-saving surgery. We present an observational retrospective study on the use of structural bone allografts in bone tumours of the long bones in our hospital between January 1993 and January 2010, with a sample of 37 patients subjected to this surgical technique. After obtaining clinic...

although various techniques have been described for treatment of severe nose deformities, these problems have high revision rates.  conventional nasal septal surgery may not be adequate for all cases. a 21-year-old male patient with nose deformity underwent a nasal surgery. patient had both functional and aesthetic nasal problems. rigid fibular bone graft was used for corrective nasal surgery. ...
