  • Patent number: 8016891
    Abstract: An orthopedic augment member and connection to an implant is disclosed. The connection may be formed between the implant, comprising a recess with a ledge formed therein, and the augment member by utilizing a fastener, and a connector, which may be configured and dimensioned to snap-fit into the recess formed in the implant forming an interference fit therebetween. The fastener may further comprise a body member with threads located thereon for matingly engaging a threaded wall defining a recess formed in the augment member, thereby securing the augment member to the recess of the implant.

  • Patent number: 7766947
    Abstract: A dynamic spinal fixation plate assembly includes a spinal plate, a receiving member, and a fastener resulting in a low profile orthopedic device. The plate may comprise a hole for maintaining the receiving member. The relationship between the receiving member and the plate may allow the plate to adjust during graft settling. The receiving member may be locked to the plate utilizing the mechanical or chemical properties of the device, or the receiving member may be configured to move and rotate freely within the plate hole, even after the fastener has been secured to the bone. The receiving member may have a tapered sidewall defining a through hole to matingly engage the fastener, which may also have a tapered portion forming a tapered lock-fit therebetween. The receiving member may comprise a lip for retaining the fastener within said receiving member.

  • Patent number: 7727281
    Abstract: A knee prosthesis includes a femoral component and a stem for implanting in a femur. A modular junction is provided for attaching the stem to the femoral component. The femoral component may include a boss having a slot for receiving the components of the modular junction. A portion of the modular junction may be placed within the slot and the modular junction may be tightened in place on the boss by threading the stem into engagement with a portion of the modular junction. Accordingly, the stem may be connected to the femoral component by a single threaded engagement and the position of the stem may be adjusted to any desired location along the anterior-posterior direction on the femoral component.

  • Patent number: 7628793
    Abstract: An orthopedic A/P cutting guide device, including a cut guide member, a support member and a positioning member for permitting both (i) rotational, and (ii) translational movement after the A/P cutting guide device has been attached to the distal femur by quick pins or other securing devices, is disclosed. Rotational movement may occur by loosening a knob thereby releasing the positioning member and the cut guide member from the support member, which may be fixed in position by the quick pins, and rotating the positioning member and the cut guide member together. Translational movement may occur by loosening a plurality of knobs thereby releasing the cut guide member from the support member and the positioning member, and moving the cut guide member anteriorly or posteriorly. After the device has been rotated and translated, the knobs may be tightened, thus securing the device from further movement.

  • Patent number: 7429346
    Abstract: An orthopedic implant device and method is disclosed. Specifically, a knee mold system is disclosed, including elastic tibial and femoral molds, each of which may be configured and dimensioned as a unitary mold for in situ placement during a surgical procedure. Each mold may be manufactured from an elastic material that may be disposable. The tibial mold may further comprise a sidewall forming a cavity, markings for relative depth measurement, and depth rings for use as a guide for scoring, cutting, and/or trimming and tearing away an excess portion of the tibial mold. The femoral mold may further comprise a sidewall defining a cavity, two legs extending from a body of the femoral mold for forming the artificial condyles, and an eyelet for aiding in placement and removal of the femoral mold. The resulting prosthetic tibial and femoral components may form an articulation surface that mimics, at least in part, the natural articulation surface of the knee.

  • Patent number: 7402177
    Abstract: An orthopedic prosthesis comprising a polymeric cup member for use in a ball and socket joint is disclosed. The cup member may include several advantageous features such as a multi-directional and multi-planar channel having an undercut area that provides a mechanical lock between the cup member and a fixation material for enhanced fixation. The cup member may further comprise a plurality of spacers for ensuring an even mantle of fixation material between the cup member and the bone, a series of divots for enhancing fixation, a locating feature that permits a physician to visualize and locate the cup member in the socket of the patient's bone on appropriate medical equipment, and a lead-in chamfer located between a terminal edge and an interior surface of the cup member. Further, the terminal edge of the cup member may comprise a planar rim or may alternatively comprise a hood located distally from said terminal edge.

  • Patent number: 6913624
    Abstract: A cementless femoral hip stem component. The hip stem component includes an elongate stem, a proximal body, and a collar disposed on the proximal body and extending outward therefrom in a sideways direction to form a ledge. The proximal body defines at least a majority of a frustoconical shape. The ledge formed by the collar includes a tapered undersurface, beneath which extends the proximal body. The tapered undersurface of the ledge and the proximal body extend in different directions and thereby cooperatively define a double-flared contact surface configured to enable subsidable engagement of said double-flared contact surface with the femur at two different rates of subsidence within the femur. An abrupt, male corner is formed by the stem and the proximal body and is sufficiently abrupt to provide enhanced bone ingrowth stimulation.

  • Patent number: 6852127
    Abstract: An intervertebral spacer adapted for implanting between adjacent vertebral bodies of a human spine as a load-bearing replacement for a spinal disc. The spacing member includes an external, non-porous, concavo-convex contour with respect to one dimension of the spacing member. The spacing member is preferably constructed from a rigid, non-resilient load-bearing material that is incapable of elastic deformation. The spacing member is inserted with the aid of a sheathed trocar device that is releasably attached to the spacer, to enable implantation and selective positioning of the spacer by the surgeon from the posterior side of the spine, without the need to retract the dural nerve or the posterior longitudinal ligament.

  • Publication number: 20030093081
    Abstract: An interference fit screw driver has a polygonal driving surface to impart torque to a corresponding surface in a screw. The end of the polygonal driving surface has a frusto-conical shaped gripping member which fits into an aperture in the screw to create a friction fit between the screw and screw driver. This allows the screw to be attached to the screw driver to facilitate installation of the screw. The friction fit is tight enough to hold the screw to the driver, yet allows the driver to be easily disengaged from the screw by pulling the driver away from the screw once the screw is lodged in place. The interference fit screw driver is particularly useful in turning bone screws into the spine of a patient during orthopedic surgery.
