2. External Iliac Artery Laceration Caused by Hip Prosthesis Migration
Resumo A artroplastia da anca é uma intervenção frequente e segura na cirurgia ortopédica. No entanto, a proximidade dessa articulação com vasos de grande calibre faz com que a ocorrência de lesão vascular maior seja uma complicação rara, mas grave e possivelmente letal, dessa técnica cirúrgica. As lesões vasculares agudas no contexto de uma art

5. Case for diagnosis. Suppurative nodule or something deeper?
Abstract: The authors report the case of a 62-year-old man with a history of total left hip arthroplasty nine years previously presenting with a large infiltrated plaque on the posterior area of the left thigh with three months of evolution without systemic symptoms or elevated inflammatory markers. Computed tomography of the left lower limb revealed a 12-ce

6. Accuracy of dose planning for prostate radiotherapy in the presence of metallic implants evaluated by electron spin resonance dosimetry
Radiotherapy is one of the main approaches to cure prostate cancer, and its success depends on the accuracy of dose planning. A complicating factor is the presence of a metallic prosthesis in the femur and pelvis, which is becoming more common in elderly populations. The goal of this work was to perform dose measurements to check the accuracy of radiotherapy

7. Investigation of Fracture in an Interface Crack Between Bone Cement and Stainless Steel
AbstractInterface strength is considered as one of the most influential factors in the long-term durability of the replaced joint in cemented total hip replacement. Several researchers have suggested that the damage initiation in a replaced joint is a mechanical phenomenon primarily taking place in the vicinity of cement-prosthesis interface. In this study,

8. Estudo de técnicas conceituais de recapeamento de quadril de cães / Study of conceptual techniques for dogs hip resurfacing
The study conceptually describes a surgical model for dog hip resurfacing technique. Hip arthroplasty was developed to restore joint mobility and relieve of human patients pain. In animals, especially dogs, total arthroplasty is a surgical procedure commonly used to correct traumatic, degenerative and inflammatory hip diseases and alleviate pain. The resurfa

9. Numerical evaluation of reduction of stress shielding in laser coated hip prostheses
The increasing use of titanium alloys as biomaterials can be attributed, among other factors, to their low Young modulus compared to other alloys with similar mechanical strength. However, Ti-6Al-4V alloy, the alloy most widely used in implants, has a stiffness of about 110 GPa, which is much higher than the typical stiffness of 20 GPa of human bone. In the

11. Effect of niobium´s content and the cooling rate on the microstructure and corrosion resistance of the Ti-Nb / Efeito do teor de niobio e da taxa de resfriamento sobre a microestrutura e resistencia a corrosão de ligas Ti-Nb
Pure titanium is used commercially as biomaterial in the manufacture of odontologic and orthopedic prosthesis, due to its high biocompatibility and good corrosion resistance. The use of the pure titanium shows deficiency in mechanical proprieties because the mechanics requests are high. When the mechanic s requests are high, like in the hip s total implant,

12. Proposta de intervenção fisioterapêutica precoce em pacientes submetidos a artroplastia total de quadril.
The loss of hip mobility, spontaneous or surgical, is an important and frequent functional impairment. In the evolvement of operative techniques of the muscoskeletal system, the cemented total hip replacement is pointed out since it improves the patients quality of life. Physiotherapy is an important resource in the patients care after Total Hip Replacement
