摘要: AbstractLumbar fusion cages are devices used in spinal procedures for disorders such as spondylosis and degenerative disc diseases that may occur due to age, trauma or genetic reasons. These most frequently made of metals polymers. The mechanical properties should be comparable the bone avoid stress shielding. Besides, interact with cells prevent extrusion achieve satisfactory fusion. In this study, poly(methylmethacrylate) (PMMA) hydroxyapatite (HAp) were compounded create products HAp contents up 40% (w/w), processed by hot melt injection molded produce composites maximum polymer-mineral interaction. morphology, interaction plates rate proliferation human osteoblast-like (HOB) studied vitro. We learned more when content is higher than 20%. Tensile compressive PMMA significantly increased increasing ...
