Quasi-static analysis of hip cement spacers

The use of temporary hip prosthesis made orthopedic cement (spacer) in conjunction with antibiotics became a widespread method used for treating prosthetic infections despite the fact that this makes bone (PMMA) more fragile. necessity to incorporate reinforcement is therefore crucial strengthen cement. In study, validated Finite Element Modelling (FEM) was analyze behavior spacers. This FEM model uses non-linear dynamic explicit integration simulate mechanical spacer under quasi-static loading. addition FEM, Extended Method (XFEM) also investigate fracture spacers reinforced titanium, ceramic and stainless-steel stems. effect material on performance analyzed. results showed numerical modelling based finite element using ABAQUS/Explicit an effective predict different spacers' behavior. simulated crack initiation propagation were good agreement experimental observations. models developed study can help designers engineers improve prostheses’ quality durability.
