Intervertebral Fixture 01

 

We designed, developed and assembled a 6 degrees of freedom (X, Y, Z, A, B, Theta) stage for multiple applications in measuring specific contact forces of artificial vertebral discs at various positions. The specific goal was to construct pressure distribution maps using contact film and correlating those forces with an compression load cell to optimize the structure of the disc replacement component. The machine used for testing was Instron’s Electropuls E1000 with a +/-2kN dynamic load cell.
