20150045801 | NATURAL ALIGNMENT KNEE INSTRUMENTS - A method for aligning an orthopedic implant in a joint replacement includes determining the bone and cartilage deficiency from an undegenerated state caused by wear of a joint. Then a resection of a bone in the joint is made based on the deficiency of bone and cartilage from the undegenerated state and the size of a joint implant so as to locate the joint surface of the implant in the undegenerated cartilage location. The condylar wear from the undegenerated states may be assessed at a distal and posterior location on each of a medial and a lateral femoral condyle. A distal cut is made on the femur at a location adjusting for the condylar wear from the undegenerated state. The distal cut varus-valgus angle is oriented parallel to a plane across the distal femur after adjusting for wear in the distal location on the medial and lateral condyle. | 02-12-2015 |
20150080717 | PATIENT SPECIFIC BONE PREPARATION FOR CONSISTENT EFFECTIVE FIXATION FEATURE ENGAGEMENT - 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. | 03-19-2015 |
20150119987 | IMPLANT DESIGN USING HETEROGENEOUS BONE PROPERTIES AND PROBABILISTIC TOOLS TO DETERMINE OPTIMAL GEOMETRIES FOR FIXATION FEATURES - An implant, and a method of designing the implant, takes into account heterogeneous bone properties. The method may be directed to designing a fixation feature of the implant using a virtual bone model. Bone property information derived from image data may be mapped to the virtual bone. A virtual model of the implant may be created, including a virtual fixation feature characterized by an input parameter. One or more simulations may be performed, the simulations being of an implantation of the virtual implant on the virtual bone. Values for at least one input parameter may be used for each simulation, each simulation resulting in a value for an output parameter. The input and output values may be analyzed to derive a relationship between the values, the relationship being used to design the fixation feature of the implant. | 04-30-2015 |
