Abstract
A system and method for a system and method for providing an electronic signature as a method and apparatus for sizing bone for press fit arthroplasty. Electrical signatures of driving motive systems used in bone preparation for the press fit arthroplasty, such as driving motors of reamers and broaches, provide a metric for proper sizing.
