Abstract
A spinal implant for an osteosynthesis device having a bone anchorage portion, a connector portion adapted for connection to an elongate rod, an extension portion extending from the connector portion, and a threaded fastener operable to secure the implant to the elongate rod. The connector portion includes a pair of flanges extending axially from the anchorage portion and spaced apart to define a channel for receiving the elongate rod therein. The extension portion includes a first segment extending axially from one of the flanges and a second segment extending transversely from the first segment toward the other of the flanges so as to define a transverse opening capable of receiving the elongate rod therethrough. The fastener is advanced along a continuous thread extending between the extension portion and the opposing flanges to secure the elongate rod within the channel. In one embodiment, the extension portion is selectively separable from the connector portion.
