The receiving member can be formed using process and plant technology from strip material, or using externally fabricated receiving members that are welded, press-welded, soldered, screwed, or riveted onto an outer side of the implant plate. The invention also comprises a method for manufacturing the implant plates.

  • Patent number: 8968370
    Abstract: Embodiments of the present invention provide methods, apparatuses, and systems for fixing dens fractures. The mode of failure for screw fixation of C2 dens fractures is often via cut-out at the anterior body. In an embodiment, securing a plate, such as a locking plate, to the anterior surface of the vertebra attached directly to an interfragmentary screw may reduce potential for anterior screw cut-out and improve construct strength. Plate supplementation of anterior screw fixation of Type II dens fractures thus improves construct strength and changes the failure mechanism from anterior screw cut-out to posterior displacement of the screw, thus improving clinical outcomes for these fractures.

  • Patent number: 8961517
    Abstract: A dynamic cervical plate includes a first end section and a second end section. In embodiments, the dynamic cervical plate may include one or more middle sections positioned between the first and second end sections. Each section may be longitudinally repositionable. Each section may include a plurality of openings for receiving threaded fasteners such as a self-starting screw or a self-tapping screw. In addition, each section may include an orifice for releasably mating with a drill guide. Each of the end sections may include a notch at one end for aligning with the drill guide or fixation pins. In one embodiment, a pin is used to interconnect the sections. In other embodiments, support bars are used to limit flexure between sections. In embodiments, one or more locking elements and/or one or more support bars may operably interconnect each section.

  • Patent number: 8956393
    Abstract: Systems for repairing acetabulum fractures can include a bone plate that has openings therein and one or more bolts sized to fit through the openings. The bone plate can cooperate with the head portions of the bolts to prevent them from spinning within the holes as screws are attached to the bolts. Such arrangements can assist in reverse implantation methods in which the bone plate is introduced into the true pelvis of a patient.

  • Patent number: 8915918
    Abstract: A bone plate system is provided herein. The system may include a first and a second bone plate, which plates may be affixed to one or more bone portions and each other, so as to align and stabilize the bone and correct a bone fracture. A first bone plate is provided which includes both a bone contacting and a top surface, one of which corresponds to a primary plane. The first bone plate may be configured to engage a bone portion and a secondary plate. A secondary bone plate is provided, which plate is configured to engage the first plate. The secondary plate includes a bone contacting surface, which corresponds to one or more planes or an arc that are provided at an angle or substantially perpendicular to the primary plane. Methods of using such bone plating systems for the reduction, restoration and treatment of bone fractures are provided.

  • Patent number: 8882769
    Abstract: A plate system is used in a surgical procedure to manage a distal radius or similar bone fracture. A plate of the plate system includes two leg segments extending downwardly from a generally horizontal segment, and further includes an elongated slot defined through the center of the horizontal segment of the plate near its top edge. A subchondral support element is inserted through the elongated slot and is advanced into the bone. The plate further defines two holes through the horizontal segment near a respective one of the two leg segments. Locking screws, such as variable angle locking screws, are inserted into and locked into the respective holes, with each locking screw advancing into the bone such that a distal tip of each locking screw engages the subchondral support element, thus providing a three-point support.

  • Publication number: 20140330275
    Abstract: Embodiments provide methods, apparatuses, and systems for fixation of a fractured bone with a bone plate. In various embodiments, the systems and plates provide elastic suspension of the receiving holes relative to an osteosynthesis plate. This elastic suspension can promote load distribution between the screws that connect a bone segment to the plate, thereby reducing stress risers and load shielding effect. In addition, stress at the screw holes, and within the construct as a whole, is reduced by incorporation of these elastic elements in the plate. Additionally, in some embodiments where fracture healing by callus formation is desired, elastic suspension of the receiving holes relative to the osteosynthesis plate can enable small, controlled amounts of relative motion between bone fragments connected by the plate. This relative motion can promote fracture healing by callus formation.
