Abstract
A bone fastener assembly including a bone screw, a receiver, a crown, a seat, and a contact pin is provided. The contact pin is formed as a leaf spring resiliently biased in a first position that affords generation of spring force via deformation thereof, and the contact pin acts as a tensioner to ultimately press against a head portion of the screw to aid movement prevention of the head portion relative to the receiver.
