ABSTRACT:
A link for connecting surgical rods to bone comprises a bone connector such as a bone screw or a bone hook, and a head connected to one end of the bone connector. The head defines an outwardly facing first recess for receiving a portion of a surgical rod which extends transversely of the link and occupies the first recess. A cover is proportioned to fit in a position to cover the surgical rod portion occupying the first recess. A hinge member is carried by the cover and head, to permit vertical pivoting retention between the cover and the head on one side of the recess. A closure on the cover and head is provided at a position opposed to the hinge member. Specifically, the closure may comprise aligned holes, plus a set screw to provide locking closure between the cover and head with a surgical rod extending through the first recess.
