<p>An instrument (10) is provided for use in orthopedic surgery for reduction of a connecting member (120) such as a spinal rod toward an anchor. The reducing instrument (10) includes an actuating assembly (12), a shaft assembly (14) extending distally from the actuating assembly (12), and a distal engaging assembly (16). The distal engaging assembly (16) includes a pair of arms (80) movable toward and away from one another in response to proximal and distal movement of a reducing member (60) of the shaft assembly (14). The arms (80) are pivotally engageable to the anchor to facilitate alignment of the shaft assembly (14) with the anchor. With the connecting member (120) extending between the arms (80) and also between the reducing member (60) and the anchor, distal movement of the reducing member (60) with the actuating assembly (12) seats the connecting member (120) in the anchor.</p> |
