  • Patent number: 10405993
    Abstract: A patient specific glenoid guide is provided to facilitate properly aligned implantation of a glenoid prosthesis into a patient. The guide shape is designed preoperatively based on the unique configuration of the scapula of the patient. The guide orientation is chosen preoperatively based on one or more of the bone structure of the patient, the wear pattern of the patient's glenoid cavity, the anchoring means of the glenoid prosthesis, or other aspects.

  • Publication number: 20190247056
    Abstract: Embodiments of the invention include an orthopedic milling machine for preparing a glenoid bone. The milling machine uses a hub and a sleeve. The hub includes reliefs arranged to cut or mill the bone and the sleeve couples to the hub to transfer rotational motion to the hub. The hub has an axial bore sized to receive an orthopedic guide pin. The hub also has a lateral passage slot that allows the hub to move laterally towards the guide pin in order to place the guide pin within the axial bore.

  • Publication number: 20190159906
    Abstract: A prosthesis assembly is provided that includes a base member (104) that has a helical structure (224) and one or more pathways. The helical structure extends between a first end and a second end. The pathway is accessible from the second end and is directed toward the first end through the helical structure. The pathway is located inward of an outer periphery of the helical structure, e.g., adjacent to an inner periphery of the helical structure. The pathway extends in a space between successive portions of the helical structure. The prosthesis assembly includes a locking device (108) that has a support member and an arm (110) I/O that projects away from the support member. The arm is configured to be disposed in the pathway when the support member is disposed adjacent to the second end of the base member. The arm is disposed through bone in the space between successive portions of the helical structure when the prosthesis assembly is implanted.

  • Publication number: 20190015119
    Abstract: A humeral guide is provided that has a first portion or member configured to be positioned on a portion of a proximal humerus. The first portion or member can be configured to rest in a complementary manner on the portion of the proximal humerus. The humeral guide can be configured with apertures defining trajectories through bone, the pin trajectories being diverging in some case and in some cases being selected to enhanced support. A second portion or member and a third portion or member of the humeral guide are configured to be positioned on first and second lateral portions of the humerus distal to a location intended for resection, e.g., between an anatomical neck and a distal end of the humerus. The second and third portions or members or portions are configured to rest in a complementary manner on the first and second lateral portions of the humerus.

  • Publication number: 20180325687
    Abstract: Embodiments of the present invention include a convertible prosthesis that is capable of conversion from a humeral head replacement to a reverse reconstruction without any removal of parts integrated into the patient's bony anatomy (e.g. implant stems). A desired overall implant inclination angle may be achieved by matching various implant stems with various reverse inserts, thus permitting a resection surface to be matched with an implant stem selection while also permitting a desired overall implant inclination angle to be achieved through the selection of an appropriate insert.

  • Publication number: 20180153701
    Abstract: The glenohumeral component of the invention comprises a first side and a second side, which are opposite each other and which, in an implanted state in which the glenohumeral component is free-floating with respect to a humerus and a glenoid of a human shoulder, are in contact respectively with an end portion of the humerus and with a glenoid component intended to be secured to the glenoid. The first side of the glenohumeral component includes a convex articular surface that is designed to articulate with a concave bone surface prepared within the end portion of the humerus. The second side of the glenohumeral component includes a concave articular surface that is designed to articulate with a convex articular surface of the glenoid component. The corresponding shoulder prosthesis is thus reversed.
