摘要：
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. The cavity is adjustable between a plurality of sizes that apply different resistances to pivoting movement of the anchor relative to the body. The adjustment may be performed before or during a surgical procedure. The adjustment may be performed by inserting different components or by rotating a threaded element to create more or less rotational interference.
