  • Publication number: 20180049788
    Abstract: Devices, systems, and methods for bone stabilization, especially volar distal radius stabilization. The stabilization system may include a bone plate having an elongated portion, an enlarged head portion, and a transition region connecting the elongated portion to the enlarged head portion, and the plate including a plurality of through holes. A plurality of fasteners may be configured to extend through one or more of the plurality of through holes in the bone plate and into the bone. The plate may be used to stabilize a fracture in a long bone, such as a radius.

  • Publication number: 20180049785
    Abstract: Devices, systems, and methods of bone stabilization. The bone stabilization system includes a bone plate having an upper surface and a lower surface configured to be in contact with bone, the bone plate having an opening extending from the upper surface to the lower surface. The opening is configured to receive a fastener, which may be either a locking fastener or a compression fastener. The locking fastener has a threaded head portion configured to engage and lock to the bone plate, and the compression fastener is configured to dynamically compress the bone.

  • Publication number: 20180000496
    Abstract: Devices, systems, and methods for bone stabilization, especially proximal humeral stabilization. The stabilization system may include a bone plate having an elongated portion extending along a longitudinal axis and an enlarged head portion extending from the elongated portion. The stabilization system may include an intramedullary nail having an upper portion and a lower portion extending from the upper portion, the upper portion and the lower portion including a plurality of holes. A plurality of fasteners may be configured to extend through one or more of the plurality of through holes in the bone plate and/or one or more of the plurality of holes in the intramedullary nail and into the bone. The plate and nail may each be used alone or in combination together to stabilize a fracture in a long bone, such as a humerus.

  • Patent number: 9743971
    Abstract: A programmable screw driver and method for affixing screws into bone is disclosed. The screw driver includes a torque sensor for measuring torsional input during screw insertion, a rotational motion sensor for measuring the rotation of the screw driver, and a microprocessor. Once a surgeon rotates a screw to be affixed to the bone, the torque sensor measures the torque and sends this information to the microprocessor. Once a predetermined torque level is attained, the microprocessor begins to measure subsequent rotation of the screw driver until a predetermined rotational limit, thereby causing a signal to be sent to alert the surgeon to stop tightening.
