  • Patent number: 9956010
    Abstract: An orthopedic fixation device comprising a bearing and a retaining portion. The bearing defines a bearing internal bore and has a rounded exterior surface, an upper surface, an intermediate surface, and a lower surface, and at least one slot in the bearing extending from the exterior surface to the internal bore.

  • Patent number: 8585705
    Abstract: An instrument for assisting in guiding a spinal connector or rod through one or more spinal implants placed in the spine includes a main assembly having the ability to accurately guide a rod through the implants by way of rotation and translation. By introducing the rod via rotation, the tip of the rod can be located very accurately deep in soft tissue for percutaneous applications. Once inside the first implant, the rod tip can be advanced by translation and rotation to the next implant. The number of implants connected in this manner is only limited to the length and curvature of the rod introduced. However, an advantage to the instrument is the ability to handle multiple length rods of different curvatures by adjustments to the instrument.

  • Patent number: 8529602
    Abstract: A self-contouring spinal rod assembly. The assembly has a proximal end, a distal end, and a length extending between the proximal end and the distal end. A plurality of rod elements extend along the length, such that each of the plurality of rod elements is in contact with an adjacent rod element. The plurality of rod elements are fixed against movement relative to each other at the distal end. The plurality of rod elements are movable relative to each other along a length proximal the distal end. A method of assembling the spinal rod assembly is also provided.

  • Patent number: 7963995
    Abstract: The present invention provides a vertebral implant comprising a wall forming two short sides (100, 101) and two elongated sides (102, 103) to define a generally elongated structure having a passageway (106) therethrough. At least one of the two elongated sides is resiliently compressible into the passageway, or resiliently expandable away from the passageway, under a force applied to the implant by movement of the spine into which the implant is placed. This resilient opposition to forces in the spine causes the device to want to return to its at-rest position, thereby aiding the spine in its return to a normal position after movement is relaxed, thereby aiding proper spine alignment. Preferably, the device comprises a flexible body having a generally loop-shaped configuration defined by the wall, wherein the wall material and thickness is selected so that the device has appropriate degrees of flexibility and strength.

  • Patent number: 6432110
    Abstract: According to the present invention a modular trial instrument having opposed ends for sizing of an implantable orthopedic prosthesis is provided. The instrument comprises a head component located at one end of the trial and having at least one connection portion and a stem component located at the other end of the trial defining a longitudinal axis. The stem component includes a tip portion and a connection portion longitudinally opposed from the tip portion. The tip portion of stem component is received in the medullary canal of a bone. It will be apparent to those skilled in the art that the trial instrument can be used for sizing an implantable orthopedic prosthesis for any limb, for example, a humerus or a femur.
