  • Publication number: 20200015830
    Abstract: Surgical procedures, tools and implants are disclosed for both conventional and reverse shoulder implant surgeries. The improved procedures, tools and implants relate to humeral head resurfacing, humeral head resection for standard implants, humeral head resection for reverse shoulder implants, glenoid resurfacing for standard shoulder implants and glenoid resurfacing for reverse shoulder implants. 3D scans and x-rays are used to develop virtual models of the patient anatomy, identify patient specific landmarks for anchoring guide wire installation blocks, templates and drill guides. 3D scans are also used to design patient specific tools and implants for the shoulder implant procedures and to pre-operatively determine the appropriate inclination and retroversion angles.

  • Publication number: 20190175238
    Abstract: A bone plate can be used to fixate one or more bones. In some examples, the bone plate defines an elongated body having a plurality of fixation holes arrayed at different points along the length of the body. For example, the bone plate may have opposed fixation holes separated by a bridge. The bone plate may be bent or shaped along a central longitudinal axis extending through the elongated body and also twisted around the central longitudinal axis. The bending and twisting can position each fixation hole of the elongated body in a different plane in three-dimensional space.

  • Publication number: 20160324555
    Abstract: An intra-osseous support structure can be used to fixate opposed portions of bone. In some examples, the intra-osseous support structure is positioned in openings formed in adjacent portions of bones. Fasteners are inserted through the bone portions to secure the intra-osseous support structure in the bones. Depending on the application, one or more external bone plates may also be applied to the bone portions. The external bone plate may be in compression while the intra-osseous support structure is in tension under load in situ.

  • Publication number: 20140114358
    Abstract: An orthopedic stabilization system of implants that includes a bone attachment means that provides poly-axial fixation of the system to the vertebrae, and a connector means that connects the bone attachment means to the spinal rod in a fashion that allows variable height adjustment of the spinal rod (dorsal in the case of posterior spinal pedicle fixation). The orthopedic stabilization system includes a locking means with a tightenable ball-joint arrangement that locks a post means to the bone attachment means in a desired relative spatial orientation. Several embodiments are disclosed, some using traditional mechanical locking means such as screw fasteners, taper-locking interfaces and collets. Embodiments are described that use the austenitic transformation of shape memory alloy (SMA) material to effect a locking of both the ball-joint arrangement and the connector means.

  • Patent number: 8529604
    Abstract: A bottom-loading multi-axial bone anchor apparatus is disclosed. The apparatus includes a receiver member, a crown member, a bone anchor and a retaining member. The receiver member defines an upper opening and a lower opening, which may form part of the same opening, a channel, and a groove. The crown member and bone anchor are loaded into the lower opening of the receiver member, and the retaining member fits around the bone anchor and into the groove in the receiver member. The bone anchor is capable of multi-axial positioning with respect to the receiver member. An elongated member is placed in the channel of the receiver member, contacting the crown member, and a compression member is applied via the upper opening. The compression member presses down on the elongated member, which presses down on the crown member and locks the bone anchor between the crown member and the retaining member.

  • Publication number: 20120095463
    Abstract: Systems for bone fracture repair are disclosed. One system includes a biocompatible putty that may be packed about a bone fracture to provide full loadbearing capabilities within days. The disclosed putties create an osteoconductive scaffold for bone regeneration and degrade over time to harmless resorbable byproducts. Fixation devices for contacting an endosteal wall of an intramedullary (IM) canal of a fractured bone are also disclosed. One such fixation device includes a woven elongated structure fabricated from resorbable polymer filaments. The woven elongated structure has resilient properties that allow the woven structure to be radially compressed and delivered to the IM canal using an insertion tube. When the insertion tube is removed, the woven structure expands towards its relaxed cross-sectional width to engage the endosteal wall. The woven elongated structure is impregnated with a resorbable polymer resin that cures in situ, or in the IM canal.

  • Patent number: 8105329
    Abstract: An instrument is provided for use in orthopedic surgery for reduction of a connecting member such as a spinal rod toward an implant such as a bone screw. An embodiment of the instrument includes handle portions that are pivotable relative to each other and biased apart, and arm portions pivotable relative to each other and to the handle portions. Distal portions of the arm portions, which may be offset from the arm portions, provide structure for engaging a connecting member and an implant. Squeezing the handle portions force the distal portions of the arm portions together, forcing together the connecting member and the implant. A toothed bar and pawl may be provided to retain the instrument in a squeezed state.

  • Patent number: RE43526
    Abstract: An introduction apparatus for approximating a longitudinal member and an implant to permit fixation therebetween. The introduction apparatus having a gripping nose for securely engaging an implant, a lateral approximation mechanism for laterally aligning an implant and an offset longitudinal member, and a reduction mechanism for reducing the vertical distance between the implant and the longitudinal member. The introduction apparatus is provide with a gripping nose actuated by axial movement of a clamping shaft in an outer sleeve. The clamping shaft further includes an axial cannula for passage of a fastener to the implant.
