摘要: A fusion cage is used to aid of an intervertebral joint. To date, cages have been commonly made materials (metals or polymers) that remain in the body. Postoperative complications with these permanent fixtures might be overcome by using biodegradable/bioabsorbable composite (BBC) cages. There are requirements for BBC as a material, including load bearing ability. The aim this study was evaluate feasibility material. This would degrade gradually simultaneously replaced bone. Post-operative reduced no foreign bodies within patient and bone growth unrestricted. design has also optimized based on material properties. Cage features such teeth holes investigated obtain suitable BBC. Finite Element Analysis carried out concept models, properties polyetheretherketone (an existing material) comparison purposes. results, from engineering view point, determined
