摘要:
Orthopedic plates (including anterior cervical plates), plate systems, and methods of use allow orthopedic screws to be placed with full visualization. This allows screw placement without use of specialized locating instruments or pins. The new plates are introduced to the surgical wound after the screws are placed and are secured by a press or interference fit. Because the screws are placed before the plates are introduced, the screws function as attachment points for distraction implements. The new plates and plate systems obviate the need to achieve a particular position and angulation of screws. The screws allow more angulation, and plate eyes adjust to screw position. Plate eyes translate to match the effective plate size to the screw placement, thereby allowing each plate to fit multiple screw spacings. Plates are adapted to adjust to bone remodeling or subsidence. Screw eyes can slide to maintain graft contact and compression.
