The posterior resections appeared so be significantly smaller than what the trumatch plan called for, about 4-5mm smaller on each side.The surgeon double checked rotation with a traditional sizer but then proceeded to use the trumatch placed distal pins for rotation and resection.They used the sized implants that trumatch planned for and the case had good results in the end, though the posterior resections were much different than the plan had originally called for.
