Abstract
A pivoting connector couples a vertebral member to a longitudinal member. An anchor is pivotally attached to a body by positioning a head of the anchor within a cavity in the body. A longitudinal rod is inserted into a channel also positioned within the body and axially aligned with the cavity. A retainer applies a force to maintain the longitudinal rod within the channel, however the force may be isolated from the anchor. One embodiment may include a compression member that is separate from or integral with the body. The compression member may transmit a rod securing force to the anchor to secure or limit the pivoting movement of the anchor member relative to the body. The compression member may deflect or detach under the influence of the securing force.
