Abstract: Disclosed herein are a reversible bone plate template and a method for using the same to size an implant. The bone plate template may include first and second portions. The second portion may be wider than the first portion and asymmetrical about a longitudinal axis. A section between the first and second portions may allow the second portion to be moved between first and second positions such that either a first or a second surface may be a bone contacting surface. A method for sizing an implant with a bone plate template may include determining whether a first or second surface is to be placed on bone, moving a portion of the bone plate template, placing it on bone and selecting an implant based upon the bone plate template.

Abstract: A technique of providing user guidance for surgical navigation is provided. A method implementation of the technique includes obtaining a predetermined spatial relationship between an optical tracking pattern and a through-hole extending through an implant, obtaining image data of the optical tracking pattern acquired by an imaging unit attached to a surgical instrument, obtaining a spatial relationship between the surgical instrument and the imaging unit at a point in time when the image data have been acquired, determining a spatial relationship between the surgical instrument and the through-hole, obtaining a plurality of predefined spatial relationships between the surgical instrument and the through-hole, and triggering simultaneous display of an indication of the plurality of predefined spatial relationships and an indication of the spatial relationship between the surgical instrument and the through-hole.

Abstract: A system for treating tissue of a patient's anatomy at a target site. A localizer generates location data associated with the anatomy. A display unit overlays visual content on the anatomy within a field of view observable by a user. A visualization program on a computing device generates a virtual reference frame, identifies viable and non-viable approaches for fixation elements to engage tissue and secure a stabilizer relative to the target site based on patient-specific imaging data, arranges a virtual viability model within the virtual reference frame based on the location data and comprising viable portions associated with viable approaches and non-viable portions associated with non-viable approaches, and renders the virtual viability model in the visual content displayed by the display unit overlaid onto the anatomy within the field of view to assist the user in visualizing at least one of viable approaches and non-viable approaches.

Abstract: An alignment guide for guiding the positioning of an acetabular cup implant includes a body having a first end and a second end. A flange extends from the first end and is adapted to rest on a labrum of an acetabulum. At least a first formation is provided at the second end which is adapted to engage with a transverse acetabular ligament of the acetabulum. A formation for accepting a trackable instrument is provided to allow a tracking system to determine the orientation of the guide.
