Patent number: 11766336Abstract: A patient specific shoulder guide is provided that includes a plurality of peripheral members coupled with a peripheral body. The peripheral members have a patient specific contact surface. An open space (e.g., a single open space) is or can be provided radially between a central channel and an inner periphery of the peripheral body. The open space(s) can extend from a side of a spoke to another side of the same or a different spoke. The spoke can be a single spoke in some embodiments. The single open space can extend more than 120 degrees between circumferential ends of the open space.Type: GrantFiled: February 8, 2021Date of Patent: September 26, 2023Assignee: HOWMEDICA OSTEONICS CORP.Inventors: Charles L.

Publication number: 20220273451Abstract: Various embodiments disclosed herein relate to stemmed and stemless humeral anchors for use in shoulder arthroplasty procedures. For example, the humeral anchor can include a first end, a second end, and an interior surface extending between the first end and the second end. The interior surface can be disposed about a recess disposed between the first end and the second end. The recess can be configured to secure a coupling of a shoulder articular body directly to the interior surface.Type: ApplicationFiled: May 23, 2022Publication date: September 1, 2022Applicant: HOWMEDICA OSTEONICS CORP.Inventors: Pierric DERANSART, Christopher K.

Patent number: 11399948Abstract: A prosthesis assembly is provided that includes a base member that has a helical structure and a cylindrical member opposite the helical structure. The cylindrical member is configured for direct connection with a reverse insert of a reverse shoulder assembly. The cylindrical member is configured for direct connection with a reverse insert spacer in some embodiments. The reverse insert can be inserted into a space defined at least in part by a wall of the cylindrical member and an inferior wall of the of the base member. The helical structure extends between a first end and a second end. The base member also can include one or more pathways. The pathway(s) 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.Type: GrantFiled: December 4, 2018Date of Patent: August 2, 2022Assignee: HOWMEDICA OSTEONICS CORP.Inventors: Kevin P.
