摘要： An augmented reality guidance system for guiding surgical operations on an articulating portion of a bone includes a tracking element to be attached to the articulating portion and-having a surface bearing against the portion that is custom-designed from a virtual model , and a three-dimensional reference mark ; a probe with a three-dimensional reference mark for probing at least three regions of a portion apart from the cartilage area; a camera for displaying and tracking the reference marks ; and a processing system for processing virtual bone model data and real-time image data from the camera to determine the position and relative direction of the tracking element and probe, to display on a display device , a three-dimensional virtual representation of a geometric datum relating to the bone model having position and direction determined by the position and direction of the tracking device and corrected after probing.

摘要： The invention relates to a shoulder prosthesis comprising a diaphyseal part extending along a diaphyseal axis and on which an epiphyseal part is mounted, the epiphyseal part having an upper face which is inclined along a front plane with respect to the diaphyseal axis, and a lower central face bearing against a complementary upper face of the diaphyseal part. According to the invention, the epiphyseal part is reversible by rotation through 180° about an axis normal to the lower central face bearing against the epiphyseal part to modify the inclination of the upper face of the epiphyseal part.
