  • Patent number: 11219528
    Abstract: An orthopedic assembly includes a tibial prosthesis that includes a body that defines an anterior side and a posterior side. The body further includes a recess in the anterior side of the joint prosthesis and a plurality of openings that extend through the body from the anterior side to the posterior side thereof. At least a first and second opening of the openings are positioned at respective lateral and medial sides of a longitudinal axis of the tibial prosthesis. A modular insert is positioned within the recess of the body such that at least a portion of the modular insert is positioned between the openings of the body. The modular insert is formed separately from the tibial prosthesis and has a porous outer surface to promote tissue ingrowth.

  • Patent number: 11202712
    Abstract: A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one fixation element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to engage a surface of an adjacent vertebral body and secure the implant between two vertebral bodies. Preferably, the implant is expandable and has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it must pass to be deployed within the intervertebral space. Once within the space between vertebral bodies, the implant can be expanded so as to engage the endplates of the adjacent vertebrae to effectively distract the anterior disc space, stabilize the motion segments and eliminate pathologic spine motion. Angular deformities can be corrected, and natural curvatures restored and maintained.

  • Patent number: 11202713
    Abstract: An assembly for attachment to a first implant component has a size and shape of a second implant component to be implanted together with the first implant component. The assembly includes a first body including a plug having a projection, and a second body including a recess having an internal surface defining at least one indentation. In a temporary configuration, when the plug is disposed within the recess and the projection is disposed at least partially within one of the at least one indentations, the first and second bodies are removably connected such that the first and second bodies are prevented from separating. A method of assembling the assembly includes removably connecting the plug of the first body into the recess of the second body by locating the projection within an indentation, such that the bodies are prevented from separating, and positioning the assembly on the first implant component.

  • Publication number: 20210378831
    Abstract: A prosthesis assembly is provided that includes a base member that has a helical structure 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.

  • Patent number: 11173048
    Abstract: 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. The virtual objects are located based on density data of the bone such that, when one or more shoulder implants are fully seated in the bone, distal portions of the implants are located in a first region of the bone having a density characteristic greater than an adjacent second region of the bone.
