  • EXPANDABLE SPINAL IMPLANT SYSTEM WITH A BIASED TIP AND METHOD OF USING SAME
    Publication number: 20240008998
    Abstract: An expandable spinal implant includes a distal projection extending from only one side of the implant, ending in an anterior tip, the anterior portion and anterior tip defining an elongated distal end hook, which is wider than the proximal end. The distal end hook rotates around the spinal cord, aligning the implant with a desired pathway, then inserts into place in the disc space between the vertebrae. The elongated widened distal end hook provides a TLIF approach, distributes loads, provides anterior rim engagement, and creates lordosis.

  • SURGICAL SYSTEM AND METHOD
    Publication number: 20230248347
    Abstract: A surgical system includes a plurality of alternate engaging surfaces. A first member is connectable with an engaging surface such that the first member is interchangeable with the plurality of engaging surfaces. A second member is connectable with an engaging surface such that the second member is interchangeable with the plurality of engaging surfaces. The members are relatively movable to distract and/or compress vertebral tissue. Surgical instruments, constructs, implants and methods are disclosed.
