摘要： A cutting block having a base, and a top connected to the base via four walls is disclosed. Each wall has an outwardly facing surface to guide a cutting tool. Each wall also has an attachment hole where a tracker may be attached. The cutting block is floated on the bone using the navigation system to position it at correct locations for the bone resection. After correctly locating the cutting block for each required cut, cutting block is fixed to the bone using pins and the bone resected. Same cutting block is suitable for resection of bone for installation of any size prosthetic device. For certain resections, the rotation angle may be mechanically set and need not be navigated.

摘要： A knee prosthesis and method for emulating movements, during flexion, of a natural knee joint replaced by the knee prosthesis, by enabling engagement and relative movement between the femoral component and the tibial component of the knee prosthesis along arcuate tracks, including rotational movement about a longitudinal axis of rotation, during flexion about a transverse axis of rotation, and maintaining the transverse axis of rotation essentially in a generally medial-lateral longitudinal plane maintained in close proximity with a generally coronal plane passing through the centers of curvature of the arcuate tracks during flexion within at least a prescribed range of flexion extending from about 0° of flexion to a predetermined degree of flexion, preferably about 60° of flexion. A stabilizing mechanism couples the femoral component with the tibial component within a portion of the prescribed range of flexion, the portion being between about 45° of flexion and about 60° of flexion, for providing stability and for assisting in maintaining the transverse axis of rotation essentially in the longitudinal plane, and the longitudinal plane in close proximity with the coronal plane as the longitudinal plane is rotated about the longitudinal axis of rotation.

摘要： 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.

摘要： Disclosed herein are systems and methods for performing total hip arthroplasty with patient-specific guides Pre-operative images of a pelvic region of a patient are taken in order to predefine the structure of the guides and corresponding implants. From the obtained image data an insertional vector for implanting an acetabular implant or component into an acetabulum of the patient is determined, wherein the insertional vector is coaxial with a polar axis of the acetabular component. Also from the obtained image data, a superior surface of the guides and implants can be shaped to match the acetabulum of the patient. A nub portion extending outwardly from the superior surface of the guides and implants is shaped to substantially match the shape of a fovea of the acetabulum. A guide portion of the guides forming a slot has a longitudinal axis coaxial with the determined insertional vector of a corresponding acetabular component.
