  • Patent number: 8388689
    Abstract: A prosthesis is provided for replacing a portion of a bone making up a joint. The prosthesis is adapted, intraoperatively, to optimize the anatomical alignment of the prosthesis in the joint. In particular, a jig is used to identify the axis of rotation of the joint intraoperatively and to align a portion of the prosthesis with the identified axis. The angle of the head of the prosthesis is adjusted to optimize contact with the appropriate corresponding portions of the joint, at which point the position of the head is fixed to prevent further rotation of the head relative to the remainder of the prosthesis.

  • Patent number: 8366781
    Abstract: A modular prosthesis system for replacement of a head portion of a proximal radius includes a monolithic stem component, a head component, and a locking mechanism formed by the stem and head components. The stem component defines a stem anchoring portion having a longitudinal axis and configured to couple to the proximal radius, and a dovetail-shaped first mounting portion on a first end face that extends in a first direction transverse to the longitudinal axis. The head component has a dovetail-shaped second mounting portion on a second end face opposite the first end face slidably engaged with the first mounting portion along the first direction. One of the first and second mounting portions intersects the longitudinal axis. The locking mechanism is formed at an interface between the stem and head components and is engaged through relative translational movement between the stem and head components. A related method is provided.

  • Patent number: 8361158
    Abstract: The application relates to a prosthetic canine elbow joint (1) comprising a radioulnar component (12) mountable in a trochlear notch of the ulna (2) and an articular fovea of a radius which is engagable with a humeral component (10) mountable on a trochlear bone portion of a humerus (4) to permit relative movement between the humerus (4) and ulna (2). The humeral component (10) is thus mounted e.g. hooked stably on a piece of bone extending between the medial and lateral condyles thereby making use of the intrinsic strength of bone. The humeral component (10) may include an opening (26) alignable with the supratrochlear foramen to receive the anconeal process (6) of the ulna (2) during articulation of the joint, thereby promoting freedom of movement.

  • Publication number: 20120290099
    Abstract: Instrumentation for a modular prosthesis having a stem and a neck comprises a handle and an adaptor. The handle extends along an axis. The handle has a distal end and a proximal end. The proximal end has a blunt surface configured to be struck. The adaptor has a male end configured to mate inside the bore of the stem. The adaptor further has a surface configured to mate with the distal end of the handle. The adaptor is configured to have a medial portion and a lateral portion. The medial portion has a relief such that the adaptor is configured to disengage the stem when the adaptor is rotated relative the stem.

  • Patent number: 8309536
    Abstract: A bone implant comprises an active agent on at least a portion thereof. The active agent is locally deliverable to bone proximate the implant in at least a two-phased release scheme. A first phase rapidly releases a first quantity of the active agent, and at least a second phase gradually releases a second quantity of the active agent, whereby bone formation stimulated by the active agent is modulated. In one embodiment, a porous implant comprises a porous portion coated with a calcium phosphate compound and which is contacted with a bisphosphonate compound to form a bisphosphonate layer chemically bound to the calcium phosphate at the surface of the porous portion and to form bisphosphonate molecules being non-chemically attached inside the pores of the porous portion. The non-chemically attached bisphosphonate molecules are released in the subject at a rate greater than that of the chemically bound bisphosphonate layer.

  • Patent number: 8257444
    Abstract: The present invention discloses an implant for use with a joint defining bone having a three dimensional shape and including a first exposed and joint surface defining layer and an inner most and bone mounting layer. The body further has at least one intermediate layer exhibiting a hardness less than either of the exposed layer and the inner most layer such that, upon mounting the body to a conditioned end of a joint defining bone, it provides the dual features of dynamic cushioning support and external wear resistance.

  • Publication number: 20120136450
    Abstract: A modular elbow prosthesis is disclosed, as well as a surgical approach and implantation technique, for using the prosthesis. The system is the first and only to allow for a, Biomechanically Anatomical, Nonconstrained, Compartmental (BANC) Elbow Arthroplasty. The modularity of the system allows it to be implanted as an unicompartmental or partial elbow replacement or a total elbow replacement. The modular elbow prosthesis for partial elbow replacement includes a cylindrical medial humeral component, a polyethylene ring thereon, and a semicircular medial ulnar component which mates with the polyethylene ring. Additionally, for total elbow replacement, the modular elbow prosthesis also includes a circular lateral humeral component, a polyethylene ring thereon, a semicircular lateral ulnar component, and a radial component. Implantation of the prosthesis is through a minimally invasive medial surgical approach with the aid of precision biomechanical guides.
