  • Shoulder prosthesis having infinitely adjustable humeral head
    Patent number: 6986790
    Abstract: A humeral prosthesis allows a surgeon to adjust humeral head position thereof in three-dimensional space with respect to a humeral component of the humeral prosthesis that has been either previously implanted into a humerus of a patient or not. The humeral prosthesis includes a conjoining component that is configured to releasably mate with the humeral component and to releasably mate with a humeral head. The conjoining component allows the humeral head to be selectively positionable from continuously infinite positions about two orthographic axes with respect to the conjoining component. The selected spatial position of the head is locked by a locking member of the conjoining component. The conjoining component allows the use of various sized heads, allow in vivo head trialing and/or exchange, and retrofit of heads for previously implanted shoulder prosthesis in need of revision.

  • System and method for delivering biological materials to a prosthesis implantation site
    Patent number: 6979336
    Abstract: In one embodiment of the invention, a method is provided including the steps of preparing an opening in the bone sized to receive a prosthesis therein and then inserting an apertured temporary implant into the opening. A fluent material is then injected into the temporary implant so that the material exudes from the apertures into contact with the bone surrounding the temporary implant. The temporary implant is then removed to make way for implanting the prosthesis into the bone opening. The fluent material can be a biological, biocompatible or bioactive material, such as a composition adapted to permanently fill voids and irregularities in the bone or a composition adapted to promote bone growth. In another embodiment, an implant assembly includes an apertured sleeve adapted to be permanently implanted within the bone opening, but providing apertures for injecting a fluent material into the opening.

  • Modular trial neck segment
    Patent number: 6977000
    Abstract: A modular trial neck segment is utilized for trialing a hip prosthesis for a total hip arthroplasty. The modular trial neck segment is preferably, but not necessarily, utilized for trialing a hip prosthesis for a total hip arthroplasty. The trial neck segment includes a mount attachable to a stem or broach, and a neck that is translatable on the mount for providing various neck offsets with respect to the mount and/or broach. Neck offset is changed via movement of the neck in a single plane of motion. This facilitates the use of the subject invention in minimally invasive arthroplasty wherein working dimensions are small. The present design replicates the biomechanics of the neck region of the implant. The mount and slidable neck provide a plurality of neck offsets and/or neck lengths for trialing a final prosthesis in a single device.
