    Abstract: Systems and methods provide patient-specific cutting blocks that allow for bone resurfacing procedures, such as milling or burring, with simplified devices. A computer assisted surgical cutting block is produced having a surface region that matches with the surface region of a patient's bone to be altered. A cutting tool may be provided having a contoured bone mating surface and a contoured and patient-specific shaped cutting guide surface, which is located in a plane above the bone mating surface. One or more channels are provided in the cutting block, and as the surgeon moves the cutting tool (a milling or burring, for example) in the channels the tool cuts the bone both laterally along the surface of the bone and vertically into the bone according to the cutting guide surface and other preselected surface features of the cutting block.

    Abstract: Patient-matched devices according to certain embodiments may include a patient-matched surface that generally conforms to a portion of the patient's anatomy, and an alignment mechanism that is positioned at a fixed orientation with respect to the patient-matched surface. In some embodiments, the alignment mechanism is an alignment post extending away from the patient-matched surface along a predetermined axis. This axis may be pre-operatively determined to correspond to (or at least indirectly reflect) the proper orientation of surgical instruments and/or implants that are used in the surgery. An alignment base and platform may selectively couple to the patient-matched device and other instruments (such as a reamer or an impactor). The surgeon may use alignment indicators on the alignment platform to ensure that the proper orientation is maintained throughout the surgery.

    Abstract: Systems, devices, and methods for accurately aligning a reference pin within a patient's acetabulum are provided. A patient's acetabular anatomy is imaged and modeled using a computer modeling approach to identify landmarks on the patient's acetabulum. A coordinate system is applied to the anatomical model, and a desired implant axis is defined based on the applied coordinate system. A guide device is created with one or more guide passages aligned with the desired implant axis for accurately placing an acetabular reference pin. The guide devices are patient-matched to an individual patient's anatomy and are expandable to provide an adequate grip on the acetabulum during pin placement. A reference pin fixed into the acetabulum provides a reference axis that corresponds to the desired implant access and can be used for alignment of tools and implants in the acetabulum.
