  • Patent number: 10695110
    Abstract: A bone fracture internal fixator for repairing a bone fracture of a femoral neck that allows load to be applied to the associated bone parts evenly, and increases the connecting strength between the femoral head and femoral shaft while minimizing the risk of the femoral head being torn apart by the inner connecting member by increasing the diameter of the inner fixing member. The central axial line of the femoral head is offset from the central axial line of the intramedullary nail placed in the medullary cavity of the femoral shaft. In order to bring the inner fixing member such as a lag screw configured to be inserted through the femoral neck close to the central axial line of the femoral neck, the central axial line of the through hole for receiving the inner fixing member is offset from the central axial line of the intramedullary nail.

  • Patent number: 9517094
    Abstract: An orthopedic intramedullary fixation apparatus and system for use in hip and femur fracture surgery comprises an intramedullary nail, a dynamic lag screw structure comprising a longitudinal sheath and a lag screw, and securing means to fix the intramedullary nail relative to a femur. A dynamic channel created by the lag screw structure allows the lag screw to adjust dynamically, and thereby may permit further compression of the fractured bone to an optimal level as a patient begins to bear weight on it following surgery. Surgical fixation may be expedited, as a favorable point of access for a lag screw may be determined readily, particularly with obese patients in whom access to the trochanter may be problematic. Complications during surgery, such as accidental fracturing of the femoral neck and head and over-penetration of the lag screw may be avoided.

  • Patent number: 9480506
    Abstract: A compression device and method for interlocking compression nailing systems provide a compression force onto fracture site and a bone fixed between proximal and distal parts of intramedullary nail to prevent stress shielding and improve healing. The compression device having pre-assembled components of set screw, elastic component, distal cap and connector screw are rotated. After nail insertion, the nail is fixed to the bone fragments by inserting the fasteners into distal bores and proximal slot. The compression device is inserted within the bore of the nail. The set screw is screwed to move elastic component and distal cap to push the proximal bone fragment distally. Distal cap overlies on fastener screw shaft to spread compression forces in fastener screw surface to prevent stress concentration. After fracture gap minimization, the set screw is screwed further to compress elastic component to provide desired compression force.

  • Patent number: 9445850
    Abstract: The present invention describes an intramedullary nail for use in orthopedic surgery for the fixation of bone fractures and fusion sites. The nail employs one or more internal loaded springs, biocompatible elastic or rubber bands, or other mechanism that provides continuous dynamic compression across the healing site throughout the healing process. By altering the size, tension and/or number of the internal compression devices, the amount of compression may be customized on a case-by-case basis. Further, the slots within the nail for its attachment can be utilized to create a torsional force when desired. The nail can have a cross-sectional shape that prevents its rotation. A system and method of use is also described.

  • Patent number: 9402728
    Abstract: A cementless femoral stem prosthesis for use in hip replacement surgery is disclosed. The stem has a collar and a body having a fixed end and a shank end. The shank end is divided into a pair of adjustable endosteal plates that are secured to the cortical bone of the femur by screws. The present invention provides an improved femoral stem structure because the screws through the endosteal plates transfer the load to the cortical bone rather than the cancellous bone, the medial endosteal plate has a plurality of spurs to engage with the cancellous bone to increase the number of stress-strain points, and the collar transfers the load directly to the cortical bone. All of these features work in tandem to reduce the risk of stress shielding, bone resorption, prosthetic loosening, and other difficulties associated with femoral stem prostheses.
