Abstract: Medical implant surface treatments and methods are described. Such a surface treatment may provide an uneven texture that is configured to interlock with adjoining bone and/or an uneven texture on another implant, such as an augment for an acetabular cup for revision hip surgery. At least one of the uneven texture of the cup bone-facing surface and the uneven texture of the augment cup-facing surface may include a web of rods. The rods may be configured to interlock with each other when the two implants are urged together.

Abstract: Systems and methods for guiding a surgical procedure based on a surgical procedure plan may include an image capture device that captures one or more images of an exposed anatomical feature of a patient. These systems and methods may also include a computing device configured to receive a surgical procedure plan based on one or more desired attributes related to an anatomical 3D model representing the exposed anatomical feature of the patient. The computing device may register the anatomical 3D model to the exposed anatomical feature of the patient based on the one or more images of the exposed anatomical feature and a projector may further provide surgical guidance information to a surgeon based on the surgical procedure plan to facilitate performance of the surgical procedure.
