  • Publication number: 20220183760
    Abstract: A method for modeling a joint before, during, and/or after a medical procedure includes receiving first imaging data capturing the joint from a first imaging perspective and second imaging data capturing the joint from a second imaging perspective that is different than the first imaging perspective, the first and second imaging data generated intraoperatively via a two-dimensional imaging modality, generating three-dimensional image data by back-projecting the first and second imaging data in three-dimensional space in accordance with a relative difference between the first and second imaging perspectives, generating a three-dimensional model of the joint based on processing the three-dimensional image data with a machine learning model trained on imaging data generated via at least a three-dimensional imaging modality, and displaying a visualization based on the three-dimensional model of the joint during the medical procedure.

  • Patent number: 8734494
    Abstract: A bone plate having a plurality of openings for receiving a compression bone screw or a cortical screw. An end cap, threadably insertable in the opening and having a layer of polymeric material interposed between the end cap and the top of the head such that the compression of the polymeric material would allow slight axial movement of the screw. Alternatively, a locking ring adapted to attach to the head of the screw and having shape complimentary to the features formed on the head. The locking ring and the bone screw being assembled together and being insertable in the bone simultaneously using a dedicated instrument. Compression may be applied to a bone fracture by turning the bone screw alone after the locking ring has reached its final axial position.

  • Patent number: 8603091
    Abstract: The invention relates to a pelvic or scapular bone plate implant having a planar or curved outer frame portion. The frame has a surface which can be aligned with a surface of a bone to which the bone plate is to be implanted. The plate has a flap portion, the outer frame portion at least partially surrounds the flap portion such that the bone contacting surface the flap portion is located within the outer boundary of the frame portion. The flap portion is connected with the outer frame portion via a material interconnection which allows the flap to be bent with respect to the frame.

  • Patent number: 8398636
    Abstract: A hip fracture device providing distance limited dynamization, load controlled dynamization and combinations of both dynamization methods by varying components. The hip fracture device includes a plate having a head portion and a shaft portion. A barrel projects from the head portion of the plate and a screw is inserted in the barrel. A friction pin is slidably connected with the screw, and an end cap is fixed to the head portion of the plate. The friction pin is fixedly connected with the end cap. The screw slides over the friction pin and toward the end cap when a load is applied on the fracture device. The load required for further sliding of the screw over the friction pin increases incrementally as the screw slides towards the end cap.
