    Abstract: A haptic robotic system for reaming an acetabulum prior to inserting an acetabular cup is more accurate than conventional instruments and may reduce the risk of dislocation and improve durability of a hip implant. Disclosed is a three-dimensional tool path, referred to as a haptic volume. Once the haptic volume is implemented into the software of a haptically constrained surgical robotic system, the cutting tool or reamer can only be utilized within the haptic volume. The haptic volume guides the surgeon in preparing the final reamed bone surface with a greatly reduced chance of the reaming unintended bone and greatly increases the chance that the reaming procedure may be carried out using one reaming tool, or using a single-stage reaming process.

    Abstract: A computer-implemented method for determining changes in parameters of a hip joint due to modification of the hip joint comprises establishing a first position of a pre-operative center of rotation of the joint in a first coordinate space. The method further comprises estimating a second position of the pre-operative center of rotation of the joint in the first coordinate space, when the estimated pre-operative center of rotation is maintained in a constant position in a second coordinate space. A change in a parameter associated with the joint is determined based on the first and second positions of the pre-operative center of rotation of the joint.

    Abstract: A system for calculating a position and orientation of an acetabular cup in computer-assisted surgery comprises a first trackable reference secured to a pelvis, with a frame of reference being associated with the first trackable reference. A device is positionable between a femoral neck and the acetabulum of the pelvis in a known relation, the device having a second trackable reference. Sensors track the trackable references for position and orientation. A position/orientation calculator calculates a position and orientation of the frame of reference and of the device and for determining an orientation of the neck axis with respect to the frame of reference from the known relation at a desired position of the femur. An implant position/orientation calculator provides cup implanting information with respect to the orientation of said neck axis as a function of the tracking for position and orientation of at least the first trackable reference.

    Abstract: A system and method for determining inclination and version of a prosthetic acetabular cup relative to a coronal radiographic plane is provided. The system and method include the identification of a coronal radiographic plane in a three dimensional medical image. The system and method further include the identification of two symmetric landmarks on the pelvis to determine a mediolateral axis. The version and inclination can then be calculated based on the relationship between the axis of the acetabular cup, the coronal radiographic plan, and the mediolateral axis.
