Abstract
A pedicle screw fastening system that consists of an anchoring bone screw having a first diameter with threads on one end for use in anchoring the screw to the bone and a spherical ball connector member having a second diameter on the other end, with the second diameter smaller than the first diameter; the spherical ball connector member operating as a pivot point about which a connecting assembly moves in a polyaxial fashion. The connecting assembly has a lower connector member with an attachment ring to secure the spherical ball connector member, allowing the use of the small diameter spherical ball connector member with a large shank anchoring bone screw. A biased retainer member maintains a positive tension between the connecting assembly and the anchored screw. The system allows for large shank screws with small connecting assemblies.
