  • Patent number: 7621913
    Abstract: A new method for locking Intramedullary Nails (IM Nails) using a headless screw for performing interlocking with the nail. A subsequent, canulated outer screw is placed in such a way that it encapsulates this headless screw. The outer screw locks to the IM Nail and holds the headless screw in place to eliminate play in the screw-nail interface and results in a more stable form of fixation.

  • Publication number: 20090287213
    Abstract: The present application relates to an implant for tubular bones and to a method for treating fractures of tubular bones. The implant is used to connect two parts of a tubular bone that has broken with a substantially smooth break. The implant is formed by a shaped piece that is intended to be inserted into the medullary cavity of a broken tubular bone. The shaped piece has at least one through-opening, which has a substantially constant internal diameter and extends substantially through the whole of the shaped piece and through which a cord can be pulled in order to stabilize the fracture. The shaped piece is made of resorbable material, and two anchor parts can be secured on the cord. The anchor parts are intended to fix the cord to the bone, and the shaped piece is intended to exploit the principle of an internally braced stack in order to press the fracture surfaces of the bone against each other.

  • Publication number: 20090275946
    Abstract: A fracture fixation system particularly useful for bones of the hand and foot is disclosed. The system uses curved shape-memory alloy (e.g., Nitinol) wires that have a predetermined radius of curvature to accommodate different sized bones. These shape-memory alloy wire forms can be inserted into phalanx, metacarpal or metatarsal bones via a percutaneous technique. The technique uses small skin incisions; a specialized drill guide that has holding K-wires to maintain fixation of the drill guide to the bone so that it does not lose the insertion point; a specialized drill as well as a specialized wire cutter and advancement tool to make sure that the level of the wire is below the level of the outer cortical bone. Shape-memory alloy (e.g., Nitinol) based wires with a pre-bent curve have an advantage over the typical standard K-wire in that they can spring back to their predetermined memory shape when inserted into the intramedullary canal of the bone and heated, i.e., a more aggressive curve.

  • Patent number: 7534244
    Abstract: Systems, devices and methods are disclosed for treating fractures. The systems, devices and methods may include one or both of an implant, such as an intramedullary nail, and a fastening assembly, such as a lag screw and compression screw assembly. The implant in some embodiments has a proximal section with a transverse aperture and a cross-section that may be shaped to more accurately conform to the anatomical shape of cortical bone and to provide additional strength and robustness in its lateral portions, preferably without requiring significant additional material. The fastening assembly may be received to slide, in a controlled way, in the transverse aperture of the implant. In some embodiments, the engaging member and the compression device are configured so that the compression device interacts with a portion of the implant and a portion of the engaging member to enable controlled movement between the first and second bone fragments.

  • Publication number: 20090112210
    Abstract: A device, system, and method for reinforcing a femoral neck bone comprises a support structure deployable from a first substantially collapsed position to a second substantially expanded position within a cancellous bone area of the femoral neck. The support structure compresses at least a portion of the cancellous bone upon expansion. A cavity created by the expansion is adapted to receive a filler material such as, but not limited to, bone cement. Upon final positioning and curing, the support structure and any filler material is adapted to interact with the healthy cortical bone and/or compressed cancellous bone and receive at least a portion of a load placed on the femoral neck bone.

    Abstract: Disclosed is a fracture fixation device, for reducing and compressing fractures in a bone. The fixation device includes an elongate body comprising a first portion and a second portion that are detachably coupled to each other. The first portion defines a helical cancellous bone anchor and the second portion defines a distal end. An axially moveable proximal anchor is carried by the proximal end of the fixation device and is rotationally locked to the first portion. The device is rotated into position across the femoral neck and into the femoral head, and the proximal anchor is distally advanced to lock the device into place. The second portion is then detached from the first portion.
