Spring-Loaded, Load Sharing Polyaxial Pedicle Screw Assembly and Method |
摘要 |
A method includes positioning a load sharing mechanism in between a screw head and a bone fixator component; attaching the screw head to the bone fixator component such that the load sharing mechanism provides tensile resistance to the screw head; securing the bone fixator component in a bone; securing a locking pin in the screw head; engaging the locking pin with the bone fixator component; inserting a longitudinal member in the screw head; and inserting a blocker in the screw head. The method may further comprise positioning a longitudinal member in a slot configured in the screw head.
