A simplified computational model of the L4-L5 functional spinal unit is presented to explore relevant parameters in minimally invasive surgeries such as percutaneous cement discoplasty. Using open-source software (Gmsh, Dolfinx, Paraview), variations in disc height and bone cement volume can be customized. The results include verification with a clinical case, estimation of injected cement volume, and analysis of pre- and postoperative stresses. This work aims to contribute to the optimization of surgical parameters.
