  • Spinal implant and methods of use thereof
    Patent number: 9962191
    Abstract: A spinal fixation device includes a housing defining a longitudinal axis, a bone screw member, a locking ring, and a crush ring. The bone screw member includes a head that is selectively securable within the housing and a threaded shaft. The locking ring is disposed within the housing and is radially expandable to a partially expanded position when the head of the bone screw member is positioned therein to retain the head within the housing. The crush ring is disposed within the housing proximal to the locking ring and adjacent the head of the bone screw member. The crush ring pushes against the head of the bone screw member when it transitions from an initial state to a deformed state when a force is applied thereto, which expands the locking ring to a fully expanded position to fix the bone screw member to the housing.

  • Spinal fixation system
    Patent number: 9924973
    Abstract: A polyaxial pedicle screw includes a housing, a bone screw member, and an anvil. The bone screw member includes a head and a threaded shaft extending from the head.
