Abstract: A computer assisted surgery (CAS) system and method for preparing an anatomical structure to receive an orthopaedic implant. The method generally involves the steps of determining a contour of the anatomical structure by using the CAS system to acquire a plurality of points on the anatomical structure and provide a best fit approximation of the anatomical structure based on the plurality of points, selecting an implant to replicate the anatomical structure, and preparing the anatomical structure to receive the implant.

Abstract: A slap hammer tool and associated instrumentation to engage with the slap hammer tool are disclosed herein. In some examples, a slap hammer tool including an end adapted for engagement with a quick release connector of an instrument is provided. The instrument can be adapted to receive the distal end of the slap hammer for engagement, the engagement being provided through rotation of the slap hammer relative to the instrument. Once the slap hammer and instrument are engageably coupled, the slap hammer can be used to provide force and accompanying motion away from the instrument in the direction of the slap hammer instrument. Force can be provided by the slap hammer tool to a coupled instrument, for example, to move or extract the coupled instrument from placement on a surgical area.

Abstract: An orthopedic guide for preparing a particular patient's bone to receive a prosthesis using a milling tool with a rotating burr comprises a platform having a top surface and a bottom surface adapted to face the patient's bone. The platform defines an elongate milling track that extends through the platform from the top surface to the bottom surface of the platform, the milling track being sized and shaped so as to be adapted to guide the milling tool across the patient's bone with the burr of the milling tool rotating beneath the bottom surface of the platform to be adapted to remove a first bone portion from the patient's bone. A plurality of legs are coupled to the platform and each comprise a referencing end that is contour-matching fabricated as a function of the patient's bone data to be adapted to abut the patient's bone, the referencing ends of the plurality of legs adapted to cooperate to locate the orthopedic guide at a single predetermined location of the patient's bone.
