Spinal instrumentation is one method of therapy for spinal damage. In such therapy, robust fixation of vertebrae by inserting rod screws is required. For vertebral robust fixation, the therapists have to understand the bone strength of the point of insertion. The purpose of this study is the fabrication of a probe to measure the thrust force during the bone drilling of bovine vertebrae and evaluate the data measured. The drilling condition such as drilling revolution, feed rate, and drill bit geometry were considered. The best condition for bone strength evaluation is selected by making a comparison of the profile of thrust-depth curve and the accuracy of the thickness of cortical bone calculation. Thrust-depth data obtained was evaluated by two regions. The cortical bone-region was evaluated by profile and mean thrust force.
