Abstract

By establishing micro finite element models of cement-bone composite materials and fusion surgery models (C4-C7), the mechanical properties of cement-bone composite materials (Polymethyl methacrylate (PMMA) and a mixture of PMMA and calcium phosphate bone cement (PMMA/CPC)) were analyzed, and the influence of bone cement on the biomechanical properties of anterior cervical discectomy fusion surgery with partial vertebral osteotomy was evaluated. The results revealed that compared with bone cement, the elastic modulus of cement-bone composite material decreased, the PMMA/CPC+bone (osteoporosis) decreased by 73.65% compared to PMMA/CPC. Furthermore, compared with the PMMA/CPC+bone (osteoporosis), the mechanical properties of the PMMA/CPC+bone (osteoporosis) composite material are closer to those of healthy cancellous bone, exhibiting a lower elastic modulus and higher strain compatibility. This study suggests that choosing PMMA/CPC as a reinforcement material may be more beneficial for cervical fusion surgery in patients with osteoporosis.
