  • Patent number: 10064631
    Abstract: Implant devices and cutting clamp apparatuses and methods for creating the implants for insertion into a patient's joint to restore anatomic length and assist in final positioning of the bones following removal of cartilage and/or bone in preparation for fusion. A first implant is a biplanar implant having a shape to mimic the normal anatomical shape of the bones the implant is configured to mate with. The first implant may be cut using a cutting clamp and jig having the anatomical shape of the bones the implant will be inserted within or between. A second implant is a cylindrical piece of bone having a convex end and a concave end for mating with bones reamed to have the opposite mating surfaces. The second implant is created using cup and cone reamers having dimensions corresponding to the size of the patient's bones. Surgical methods for inserting the implants within a patient.

  • Patent number: 8764842
    Abstract: A method and apparatus for correcting malformed joints, in particular the “hammer toe” contraction of the proximal interphalangeal joint. The disclosure comprises a two-component implant: a proximal phalanx component and a middle phalanx component. An endosseous stem on each component is inserted axially into the end of a respective host bone and, after insertion, the components are attached. The attached components are held together in various ways, for example a detent arm/aperture mechanism. Each component can be cannulated to allow for the passage of a kirschner wire, if necessary, to stabilize adjacent joints such as the proximal interphalangeal joint. The bones of the treated joint can be set to form a desired angle by adjusting the angle formed by the corresponding endosseous stems.

    Abstract: An artificial toe joint utilizes a ball in socket joint structure and arms or side walls which are exterior to the bone, the side walls extending around depressions in the metatarsal bone or phalangeal bone, respectively so as to not interfere with sesamoid bones or the attachment of tendons. The resulting joint provides improved strength and durability, and may be used to repair joints which are not suitable for installation of a prior art artificial joint.

  • Publication number: 20110093085
    Abstract: An artificial joint utilizes a ball in socket joint structure, an insert and arms or side walls which are exterior to the bone. The insert may be configured to adjust joint distance and/or correct joint angle by adjusting thickness and tapering. The resulting joint provides improved strength and durability, and may be used to repair joints which are not suitable for installation of a prior art artificial joint.

    Abstract: A surgical implant having an elliptically-shaped base, a bottom surface, a peripheral rim and a top surface, the top surface having a concave portion. The stem extends from the bottom surface, and includes a core, a first wing portion extending laterally outwardly from the core and a second wing portion extending laterally outwardly from the core. Each of the first and second wing portions has a laterally outermost edge, said edge having at least one tooth portion projecting laterally outwardly. There is a cannulation extending through the base and the core of the stem.

  • Publication number: 20100331984
    Abstract: An elongate, longitudinally oriented outer sleeve includes an outer sleeve surface and has a sleeve body. A stem-receiving cavity extends from a distal sleeve end into the sleeve body. The distal sleeve end includes a sleeve interference protrusion extending from the distal sleeve end away from the sleeve body. A joint articulating member includes an elongate, longitudinally oriented stem. The joint articulating member includes a joint articulating surface spaced apart from a distal stem end by an angularly extending connector neck. When the stem is inserted into the stem-receiving cavity, the stem and the outer sleeve are configured for selective relative rotation about a shared longitudinal axis, and the connector neck impinges upon the sleeve interference protrusion responsive to a predetermined amount of relative rotation between the stem and the outer sleeve to prevent relative rotation between the stem and the outer sleeve outside a predetermined range of allowable rotation.

  • Publication number: 20100262254
    Abstract: A metatarsal implant (212) for insertion into a stem aperture (25) in a metatarsal (14) bone of a foot and to form a joint with the proximal phalanx (16) of the great toe, includes a head (226) and a stem (228). The head (226) includes an articular joint engaging surface (232) and an opposed, bone engaging surface (230). The stem (228) cantilevers away from the bone engaging surface (230), and is adapted to be inserted into the stem aperture (25). The stem (228) can have a stem axis (228A) that is at an angle (234) of between approximately 45 and 75 degrees relative to the bone engaging surface (230). The stem axis (228A) can also be at an angle (266) of between approximately 40 and 80 degrees relative to a tangential reference line (234) drawn from the articular joint engaging surface (232). In one embodiment, the stem axis (228A) is at an angle (266) of between approximately 50 and 70 degrees relative to the tangential reference line (234) of the articular joint engaging surface (232).

  • Publication number: 20080221697
    Abstract: An improved implant for use primarily within the first metatarsophalangeal joint. The implant includes an elliptical, concave, joint surface positioned on a stem and is designed to be placed into a prepared proximal face of the phalanx. The implant is sized according to the patient and may be provided in a number of standard incremental sizes. The improvements relate primarily to the structure, size, and position of the stem that extends into the phalanx to support the implant. The stem is off-set from a center axis of the elliptical joint surface. This off-center placement allows for a longer stem. Single deep indentations on each side of the stem facilitate retention within the bone. A size selection tool is provided to facilitate the selection and placement of an appropriately sized implant. The tool further provides a template for positioning and placing the stem in the phalanx.

  • Publication number: 20080221698
    Abstract: A first carpometacarpal joint implant. One embodiment of the invention includes proximal and distal components. The proximal component includes a fixation portion for attachment to one or more elements of a patient's distal carpal row, a ball-type joint portion cantilevered off the fixation portion, and a skid having a concave surface opposite the ball-type joint for engaging a patient's scaphoid bone. The distal component has a fixation portion for attachment to a patient's thumb metacarpal, and a socket-type joint portion that cooperates with the ball-type joint portion of the proximal component.
