  • Patent number: 10716605
    Abstract: Embodiments provide methods, apparatuses, and systems for fixation of a fractured bone. In various embodiments, the systems and plates may provide elastic suspension of the receiving holes relative to the osteosynthesis plate. This elastic suspension may 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, for instance if fracture healing by callus formation is desired, elastic suspension of the receiving holes relative to the osteosynthesis plate may enable small, controlled amounts of relative motion between bone fragments connected by the plate, which may promote fracture healing by callus formation.

The plate has a Y-shaped profile or an X-shaped profile which includes an elongate central trunk with a complex contour and either one or two terminal pairs of arms that have a first arm and a second arm that form differing angles and lengths relative to the trunk portion of the plate. The arms include locking screw holes where the screws converge toward each other to provide for multiplanar fixation but which do not impinge.

  • Patent number: 9220548
    Abstract: A fixation system includes a plate comprising a top surface, a bottom surface, a central longitudinal axis, at least one fixation hole extending between the top and bottom surfaces and comprising an undercut therein, and at least one passage intersecting one of the undercuts. At least one resilient clip is disposed in at least a portion of the undercut, with the at least one clip having a pair of generally parallel sides and an end tab. At least one fastener is provided and comprises a head and a threaded shaft, with the head comprising a perimetral groove extending around at least a portion thereof and an instrument receiving portion. The at least one clip is configured and dimensioned to seat in the undercut with the end tab extending within the passage, and the at least one fastener is configured and dimensioned to be received in the at least one fixation hole and securable therein when the at least one clip abuts the perimetral groove of the head.

  • Patent number: 9198769
    Abstract: In one aspect, a bone anchor assembly is provided having a bone anchor with a head, a resilient locking cap extending about a portion of the bone anchor head, and a cap drive member having a depending annular wall. The annular wall and locking cap have engagement surfaces configured to engage and expand the locking cap as the cap drive member is shifted from an unlocked to a locked position. In another form, a bone plate system is provided including a bone plate having an elongated throughbore and a resilient support member received therein. The support member has an opening sized to receive a bone anchor head and an actuator device carried thereon. The bone plate and support member have interfering portions configured to be shifted to a locked orientation to lock the support member and the bone anchor head at an axial position in the throughbore.

  • Patent number: 9173688
    Abstract: The invention is related to medicine and, in particular, to a class of implants intended for osteosynthesis i.e. in the treatment of essentially all kinds of bone fractures. It is the aim of the present invention to eliminate the above contradiction and to design a bone implant and a spacer thereof that would not cause periosteum necrosis and osteoporosis of the bone and also a method of placing a bone implant of the kind. This aim is achieved by using polytetrafluorethylene, in particular, in the form of a porous surface three-dimensional structure as a spacer for a support surface of a bone implant.

  • Patent number: 9149310
    Abstract: A bone plate including a first side and a second side and configured to locate a locking screw and a compression screw. The bone plate includes a top surface and a bottom surface each extending between the first side and the second side. A plurality of holes extend from the top surface to the bottom surface include a hybrid screw hole configured to accept both a locking screw and a compression screw, a first form hole configured to accept a locking screw, and a second form hole having an elongated shape with a non-circular cross-section configured to accept a compression screw. An interior wall of the bone plate extends between a top opening and a bottom opening of the hybrid screw hole wherein the interior wall includes a threaded first portion proximate the top opening and an unthreaded second portion extending from the bottom opening.

  • Patent number: 9107712
    Abstract: A bone plate system for the internal fixation of metacarpal and phalanx fractures of the hand is provided. The plates are structured to permit independent reconfiguration of holes of the plates relative to a longitudinal axis and are configured to orient fasteners to interdigitate with holes displaced along the longitudinal axis. The plates are very thin, and a locking screw with a low profile head design is provided for use therewith.
