Including An Intermediate Bearing Cup Patents (Class 623/21.17)
  • Patent number: 9675392
    Abstract: A method includes inserting a first surgical device into an exposed first end of a first bone until a trailing end of the first surgical device is disposed adjacent to the first end of the first bone. A second surgical device is inserted into an exposed first end of a second bone while the first surgical device remains disposed within the first bone. A first portion of an implant is advanced into the second bone while being engaged with a passageway defined by the implant such that the implant is guided by the second surgical device. The second surgical device is removed from the second bone and from its engagement with the implant. The first bone is repositioned such that the first surgical device is aligned with the passageway defined by the implant, and the first bone is forced into engagement with a second portion of the implant.

  • Patent number: 9138323
    Abstract: A finger joint prosthesis is provided including a joint body having first and second joint elements, which are connected together pivotably about a rotary axis and from each of which extends an anchoring bar for fixing to a proximal and/or distal phalanx. The anchoring bars have eyes with openings for receiving fixing screws. To increase stability, it is proposed that the first joint element have an external hollow body with an insertion opening, that the second joint element have an internal hollow body, and that the internal hollow body in the position of installation can be inserted by way of the insertion opening relatively movably into the external hollow body. A spindle can be inserted in the position of installation into the internal hollow body for rotationally movable connection to the external hollow body.

  • Patent number: 8556981
    Abstract: An implant having a porous tissue ingrowth structure and a bearing support structure is disclosed. The implant includes a metal insert having a bone ingrowth structure, an intermediate structure and a bearing support structure. A bearing surface is formed from a polymer material and attached to the bearing support structure. The intermediate structure has a porosity sufficient to inhibit the polymer material from translating through the bearing support structure to the bone ingrowth structure.

  • Publication number: 20130079886
    Abstract: A multi-component thumb joint assembly incorporated into reconditioned end surfaces established between upper metacarpal and opposing lower proximal phalanx bones. A first component is anchored into a reconditioned end surface of the metacarpal bone and exhibits a first exposed support surface. A second component is anchored into a reconditioned end surface of the proximal phalanx and exhibits a second exposed support surface. An intermediate and spherical shaped component is supported in at least one of eccentric or rotational fashion between the first and second anchored components.

  • Patent number: 8377142
    Abstract: A distal component for an interphalangeal prosthesis suitable for insertion into a proximal end of a distal phalangeal bone includes a stem portion shaped to be received within a surgically prepared bore in the proximal end of the distal bone. A head portion has an under-surface and an upper-surface, the under-surface of which in use will bear on the bone into which the stem is implanted.

  • Patent number: 6699290
    Abstract: A modular elbow prosthesis includes a humeral and ulnar components and three bearing components. The ulnar component includes a stem and a body including a slot. Two of the three bearing components include flanges that mate with the slot of the ulnar component. The humeral component includes a stem and two arms extending from one end of the stem. An opening is formed in each arm and in two of the three bearing components. The modular elbow may be used in an unconstrained mode by attaching one bearing component to the ulnar component and the other to the humeral component by inserting a pin through the openings in the arms and the bearing component. The two bearing components are then placed adjacent each other such that they articulate about their bearing surfaces.
