PATIENT SPECIFIC BONE PREPARATION FOR CONSISTENT EFFECTIVE FIXATION FEATURE ENGAGEMENT

摘要

An optimized press-fit between a resected bone and an articular implant may, for instance, reduce undesirable qualities, including excess micromotion, stress transmission, and/or strain. By taking into account heterogeneous bone properties, the parameters of a bone resection can be determined as to optimize the press-fit between a resected bone and an articular implant. An optimized press-fit is obtained by determining ideal engagement characteristics corresponding to the fit between the fixation features of an articular implant and a bone. Then, taking into account a bone's heterogeneous properties, the parameters of a bone resection that would substantially achieve the determined ideal engagement characteristics are determined.

主权项

1. A method of determining one or more parameters relating to bone quality of at least one joint, the method comprising the steps of:
obtaining bone quality data corresponding to a bone of the joint; determining one or more desired engagement characteristics corresponding to a desired press-fit between a fixation feature of an implant and the bone; and determining the one or more parameters based on the bone quality data in order to substantially achieve the one or more desired engagement characteristics between the bone and the fixation feature.
