In one embodiment, the plate is formed from titanium alloy, while the bushing is formed from a cobalt chrome alloy. The outer surface of the polyaxial bushing includes a plurality of spikes. When the screw is inserted into the bushing, since the bushing material is considerably harder than the plate material, the forceful expansion of the bushing during screw insertion causes the spikes to penetrate into the inner spherical surface of the hole, thereby increasing the frictional engagement of the bushing to the plate to lock the screw at a desired angle.

    Abstract: A spinal plating system for vertebral fixation includes a plate, a compression screw, multiple fixation members and polyaxially adjustable locking rings. The plate is shaped to conform to the curvature of the spine and the surfaces of the vertebral bodies. The compression screw fits through an insert, and together they are guided by the plate as the screw is driven into one of the vertebrae, producing compression between the adjacent vertebrae. A retaining lip on the plate prevents backout of the compression screw. The polyaxial locking rings can be polyaxially pivoted to attain a desired orientation, and are lockable to the plate to maintain the orientation. The fixation members fit through openings in the polyaxial locking rings and the plate to fix the plate to the vertebrae. Locking the polyaxial locking rings fixes the position of the fixation members relative to the plate, and prevents backout of the fixation members.

  • Publication number: 20090036930
    Abstract: A bone fixing device (10) for fixing bone pieces together. The bone fixing device has a pair of spaced apart fixing portions (12), each having at least one hole (14) dimensioned such that a bone screw can extend there through; and a pair of substantially rigid connecting members (18) extending between the fixing portions, the connecting members being deformable without substantially losing rigidity. In use, each fixing portion is fixed to one or more of the bone pieces by a respective one of the bone screws such that the connecting members extend across one or more fissures between the bone pieces. The connecting members are simultaneously deformed such that the fissures are closed with the bone pieces held in compression.

  • Publication number: 20090030467
    Abstract: A bone plate having a rear face and opposing front face, adapted to be abutted on a bone, and a through hole extending between the front and rear faces, and attached to a bone to be set by applying the bone plate to the bone, and by screwing a screw into the bone through the through hole. The bone plate has a blind first dimple provided in at least one of the faces thereof other than the rear face. One acute gripping tip of a pair of bone forceps may be abutted on the bone, with the other acute griping tip of the bone forceps being engaged in the first dimple. The first dimple is configured so as to converge from an opening portion thereof on the dimple-provided face toward a bottom portion thereof, whereby the other acute gripping tip of the bone forceps can slide toward the bottom portion.
