    Abstract: The invention relates to a joint part prosthesis, particularly for a finger joint, consisting of either a proximal or a distal component, as well as a shaft that extends away from this component, to be mounted in a bone, which shaft is configured with a fin-like anti-twist device. According to the invention, it is provided that as an anti-twist device (7), at least two anti-twist elements (8) are disposed on the mantle surface (6) of the shaft (4), with rotation symmetry, and extend radially away from this mantle surface (6) and in the longitudinal direction of the shaft (4), whereby the distance of the anti-twist elements (8) from the mantle surface (6) decreases slightly in the direction toward the free end (5) of the shaft (4).

  • 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.

  • Publication number: 20120323338
    Abstract: A method for replacing a proximal interphalangeal joint with a modular implant assembly is provided. During a first surgical procedure, a first stem component of the implant assembly having a first articulation component removably attached thereto is implanted in a proximal phalanx bone. A second stem component of the implant assembly having a second articulation component removably attached thereto is implanted in a middle phalanx bone. During a second surgical procedure performed after the first surgical procedure, the first articulation component is removed from the first stem component and the second articulation component is removed from the second stem component. A third articulation component is attached to the first stem component and a fourth articulation component is attached to the second stem component. The second surgical procedure is performed without removing the first stem component from the first bone and without removing the second stem component from the second bone.

  • Patent number: 8268007
    Abstract: An elongate, longitudinally oriented outer sleeve includes an outer sleeve surface defining a radially oriented proximal sleeve border, a radially oriented proximal sleeve rim intersecting the outer sleeve surface at the proximal sleeve border, an outer sleeve body enclosed by the outer sleeve surface and the proximal sleeve rim, and an elongate, longitudinally oriented stem-receiving cavity formed in the outer sleeve body and intersecting the proximal sleeve rim to define a stem-receiving aperture. A joint articulating member includes an elongate, longitudinally oriented stem, an articulating surface, and an interface rim. When the stem is at least partially inserted into the stem-receiving cavity, the proximal sleeve rim and the interface rim interact to change a longitudinal relationship between the outer sleeve and the joint articulating member responsive to relative radially-oriented rotation between the stem and the stem-receiving cavity.

  • Publication number: 20120179267
    Abstract: An implant for the trapezium of the thumb carpometacarpal (CMC) joint comprising an integral elastomeric member configured to include a body portion having a tapered neck, having extending from one end thereof an elongated, longitudinally extending tapered portion adapted to be embedded into a reamed out-channel in the thumb metacarpal bone. After implantation, in the preferred embodiment of the method according to the invention, a segment of a nearby tendon, for example, the APL or FCR tendons, may be wrapped around the tapered neck of the implant to secure it in position, thereby forming a reinforced structure to inhibit dislocation of the prosthesis. However, in other methods, various other securing elements, including, but not limited to acellular matrices, may be used to retain the implant in position.
