Patent number: 11129724Abstract: 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.Type: GrantFiled: June 22, 2017Date of Patent: September 28, 2021Assignee: HOWMEDICA OSTEONICS CORP.Inventors: Kevin P.

Publication number: 20210228371Abstract: 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.Type: ApplicationFiled: April 12, 2021Publication date: July 29, 2021Applicant: Tornier Orthopedics Ireland, Ltd.Inventors: Pierric DERANSART, Vincent GABORIT, Brian MARONEY, Brian C.

Publication number: 20210220151Abstract: Various apparatus and methods for implanting glenoid prostheses are disclosed. In various embodiments, a method for performing shoulder surgery can include guiding a guide pin into the glenoid surface along a reaming axis. A partial reaming guide can be placed in contact with the glenoid surface over the guide pin. A reamer can be guided over the guide pin to ream the glenoid surface. The reamer can be further advanced over the guide pin until the reamer contacts the partial reaming guide, whereby such contact limits reaming to only a portion of the glenoid surface.Type: ApplicationFiled: February 10, 2021Publication date: July 22, 2021Inventors: Pierric Deransart, William J.

Publication number: 20200345518Abstract: Methods of implanting a prosthesis to repair a joint include displacing a first bone from the joint formed by an intersection between the first bone and a second bone. An end portion of the first bone is resected to define a resected end. A concavity is formed into the resected end using a shaping tool. The bone is compacted to form a support layer lining the concavity. The prosthesis is implanted in the concavity against the support layer without attaching the prosthesis to the support layer. The joint is reformed with the prosthesis such that the prosthesis remains unattached to the support layer and the first and second bones articulate about the prosthesis.Type: ApplicationFiled: May 15, 2020Publication date: November 5, 2020Inventors: Michel Hassler, Gilles Walch, Pierric Deransart, Lucile Ferrand, Pascal Boileau
