摘要：
A spinal plating system for vertebral fixation includes a plate (12), a compressionscrew (18), multiple fixation members (14) and polyaxially adjustable lockingrings (16). The plate (12) is shaped to conform to the curvature of the spine andthe surfaces of the vertebral bodies. The compression screw (18) fits throughan insert, and together they are guided by the plate (12) as the screw is driveninto one of the vertebrae, producing compression between the adjacent vertebrae.A retaining lip on the plate prevents backout of the compression screw (18). Thepolyaxial locking rings (16) can be polyaxially pivoted to attain a desired orientation,and are lockable to the plate (12) to maintain the orientation. The fixation membersfit through openings in the polyaxial locking rings (16) and the plate (12) tofix the plate to the vertebrae. Locking the polyaxial locking rings (16) fixesthe position of the fixation members relative to the plate (12), and preventsbackout of the fixation members (14).
