Patent number: 11833056Abstract: A stemless prosthetic shoulder joint may include a prosthetic humeral head and a stemless base. The stemless base may include a collar and an anchor extending from the collar intended to anchor the base into the proximal humerus. The anchor may include various features to enhance the fixation of the base, including hooks, threads, and/or expandable members that may be transitioned from a contracted insertion condition to an expanded implanted condition once the base is positioned in the bone. The anchor and/or collar may also include additional features to enhance fixation, such as geometries and surface features to enhance fixation to bone. The anchor may include a plurality of chisel slots to facilitate removal of bone during a revision surgery.Type: GrantFiled: December 21, 2021Date of Patent: December 5, 2023Assignee: Howmedica Osteonics Corp.Inventors: Philip T. Kemp, Andrew J. Nelson, Jan Heinsohn, Rajan Yadav, Koustubh Rao, Gennaro A. Barile, Ashish Mehta, Venkateswaran Perumal, David Viscardi

Publication number: 20230090775Abstract: A method of repairing a fractured bone may include implanting a prosthetic stem into an intramedullary canal of the fractured bone. First and second bone segments of the fractured bone may be robotically machined to include first and second implant-facing surfaces that are substantially negatives of first and second surface portions of the first end of the prosthetic stem. The first and second tuberosities may be machined so that the first and second bone segments have first and second interlocking surfaces shaped to interlock with each other. During implantation, the first and second implant-facing surfaces are in contact with the first and second surface portions of the first end of the prosthetic stem, and the first interlocking surface interlocks with the second interlocking surface.Type: ApplicationFiled: November 29, 2022Publication date: March 23, 2023Inventors: Rajan Yadav, Koustubh Rao, Andrew J.

Patent number: 11559405Abstract: A method of repairing a fractured humerus may include implanting a prosthetic humeral stem into a humeral canal of the fractured humerus. First and second tuberosities of the fractured humerus may be robotically machined to include first and second implant-facing surfaces that are substantially negatives of first and second surface portions of the proximal end of the prosthetic humeral stem. The first and second tuberosities may be machined so that the first and second tuberosities have first and second interlocking surfaces shaped to interlock with each other. During implantation, the first and second implant-facing surfaces are in contact with the first and second surface portions of the proximal end of the prosthetic humeral stem, and the first interlocking surface interlocks with the second interlocking surface.Type: GrantFiled: February 4, 2021Date of Patent: January 24, 2023Assignee: Howmedica Osteonics Corp.Inventors: Rajan Yadav, Koustubh Rao, Andrew J.

Publication number: 20220117666Abstract: Robotic systems and methods for robotic arthroplasty. The robotic system includes a machining station and a guidance station. The guidance station tracks movement of various objects in the operating room, such as a surgical tool, a humerus of a patient, and a scapula of the patient. The guidance station tracks these objects for purposes of controlling movement of the surgical tool relative to virtual cutting boundaries or other virtual objects associated with the humerus and scapula to facilitate preparation of bone to receive a shoulder implant system. In some versions, planning for placement of a stemless implant component is based on a future location of a stemmed shoulder implant to be placed in the humerus during a revision surgery.Type: ApplicationFiled: December 27, 2021Publication date: April 21, 2022Applicant: MAKO Surgical Corp.Inventors: David Viscardi, Jan Heinsohn, Andrew Nelson, Phil Kemp, Rajan Yadav, Jetinder Singh, Koustubh Rao

Patent number: 10390972Abstract: Orthopedic trialing systems include a stem, an adaptor and a trial member. The stem may be a trial or implant stem. The trial member may be a cup or head. The adaptor is used to account for the difference in the coupling of the trial member and stem and an implant member and stem. The stem has a first coupling feature and a shaft portion adapted to be received in a canal of a bone of a patient. The adaptor has planar top and bottom surfaces and at least one aperture therethrough. The trial member has a second coupling feature, wherein one of the first and second coupling features of either the trial member or stem extends through the aperture of the adaptor and at least partially into the other of the first and second coupling features for coupling together the trial member, the adaptor and the stem.Type: GrantFiled: January 15, 2016Date of Patent: August 27, 2019Assignee: Howmedica Osteonics Corp.Inventor: Koustubh Rao
