the finite element method (fem) is one of advanced methods in modeling of solid mechanics used in the design and analyzing of prosthesis in the human body. one of the important factors in designing a femur (the linkage between basin and knee) which is under complicated stresses is to minimize the amount of the stress in the components of the prosthesis due to the body weight. in this research t...

To be human is great; to look human is wonderful! It is nature's greatest gift! Mother nature's womb is the safest place on earth for any life, but the calamity strikes and no one knows how Hence, Treasure your exceptions!, since nature seems nowhere accustomed more openly to display, its secret mysteries than in cases where it shows traces of its workings apart from the beaten path. A dismorph...

Background & Aims: The orbital cavity is an important anatomic structure in the face. It is in close connection with the skull, paranasal sinuses, and the nose. Precise knowledge of the orbital cavity dimensions can be helpful in the diagnosis and treatment of diseases associated with the orbital cavity. Due to the lack of adequate research on orbital size in Iran and the city of Kerman, the ai...

OBJECTIVE To determine the orbital tolerance of a microporous implant fitted with an integrated stainless steel post and the enhanced motility associated with magnetic coupling of the prosthetic and the implant in a rabbit model. METHODS Six New Zealand white rabbits underwent primary enucleation with implantation of a 12-mm microporous polyethylene implant with a 2 x 3-mm stainless steel pos...

Hemophilic pseudotumor (HP) is a rare complication of hemophilia, which occurs in a wide spectrum of bones and soft tissues. A case of a massive femoral HP in a Chinese adult is reported. With adequate infusion clotting factor VIII replacement therapy in the perioperative period, the patient had a radical resection of HP and reconstruction with a custom total femoral prosthesis. The patient was...

orbital lynphangioma is a low-flow or no-flow vascular malformation. it is a congenital and isolated hemodynamic lesion in which the clinical presentation and onset are related to orbital, peri-orbital or intracranial involvement. in addition, history of previous trauma and upper respiratory tract infection are important predictor factors. high resolution mri, doppler ultrasound and ct-scan are...

Introduction: Recently the most accurate diagnostic method in the diagnosis of prosthesis infection is the combination of Tc-99m labeled leukocyte/bone marrow imaging. However the diagnostic efficiency of the test is influenced because of its low spatial resolution. Recently SPECT/CT imaging is implicated in this test with efficient additional diagnostic improvement. In the dep...
