  • Publication number: 20260090842
    Abstract: A surgical navigation system is provided to create a plan to correct a deformed spinal alignment. A processor is configured to obtain a first set of image data associated with a deformed alignment in a spine of a patient from at least one imaging device. The processor is also configured to process the first set of image data to identify a set of deformed alignment parameters associated with the deformed alignment. The processor is further configured to identify a set of corrected alignment parameters. The processor is also configured to process the first set of image data, the set of deformed alignment parameters, and the set of corrected alignment parameters to generate a correction plan to surgically manipulate the deformed alignment to the preferred alignment. The processor is additionally configured to provide navigation through the correction plan to facilitate surgical manipulation of a patient spine to the preferred alignment.

  • Publication number: 20260083480
    Abstract: An orthopedic fixation device for affixing the screw head of a polyaxial pedicle screw has a tulip, a saddle, and a ring. The tulip has an interior cavity and two opposed threaded arms and a lower ledge. The saddle is inserted into the tulip body, and has a U shaped groove for receiving a spinal fixation rod. The ring has a diameter that is smaller than the widest diameter of the screw head, and is formable into a diameter larger than the widest diameter of the screw head when the screw head is pushed into the ring. The ring has a connection portion that mates with a connection portion of the saddle. The screw head is clamped within the tulip body between the saddle and the ring when a cap is threaded between the tulip arms.

  • Publication number: 20250345128
    Abstract: Navigated force sensing instrument, systems, and methods. The navigated force sensing instruments may be used for applying forces to correct the spine, for example, in compression, distraction, reduction, and/or derotation. The trackable instrument includes markers viewable and trackable by a navigation system, including rigid and movable markers. The trackable instrument includes a flexible portion located between the rigid and movable markers. When a surgical task is performed, the markers indicate the amount of force applied to the instrument and/or a stiffness of the spine.
