A spinal training simulator kit with an operable module unit for surgical training is described. The spinal training simulator kit includes an anatomical base model of at least a portion of a spinal column and at least one high-fidelity module unit, the module unit comprising intervertebral disc analogues and vertebral segment analogues, and the module unit configured to fit within the base model in an anatomically correct orientation and location. The module unit may be acted upon, i.e. surgical instruments may be passed through, thus, providing a realistic simulator for surgical training.
