Abstract
Embodiments of a device and method for connecting a bone fastener, for example a spinal screw, to an elongated member are disclosed. In one embodiment, a body having channels to receive the fastener and elongated member is tapered and has an aperture for a locking member. A tapered washer slides over the body. The tapered washer has an inner diameter that is smaller than part of the tapered portion of the body allowing it to engage the body. The fastener passes through the body and engages the washer. An offsetting member slides over the body. The body slides over the elongated member and the offsetting member offsets the elongated member from the spinal fastener and contacts each in two differing locations. A locking member is inserted into a threaded aperture in the body to apply a compressive force that compresses all of the members preventing relative motion of the components.
