    摘要： A portal (100) for use in a spinal implantation procedure is disclosed herein. The portal (100) includes base (102) and first and second paddles (104,106) pivotally coupled to the base. The paddles (014, 106) can be pivoted between a distraction orientation and an insertion orientation. In the insertion orientation, the paddles (104, 106) are adapted for insertion between vertebrae that are in need of distraction. In the distraction orientation, the paddles are adapted to hold the vertebrae spaced apart at a distracted spacing. In the distraction orientation, the portal (100) defines a portal window (109) for accessing the disc space between the two distracted vertebrae.

    摘要： A surgical instrument for accessing first and second pedicle locations of a spinal column area includes a blade member (20) slidably positionable along first and second wires (14, 16). The instrument has a nested arrangement (12) of members, including a portal member (18) having an elongated aperture (74) to access the first and second pedicle locations. The nested arrangement further includes a plurality of members (24, 26) configured and sized to incrementally expand the access opening to the spinal column area.

    摘要： Connectors (100,300) for interconnecting rods (150,152,340,342) fixed to vertebrae and other bones of a subject include a body portion (104,122,304,322) and two recesses (111,129) or pockets (306,324) for receiving the rods. These connectors are generally able to be secured to the rods by a tightening, a fastener (112,130) or retaining member (310,328) from above the spine, which can facilitate the procedure for the surgeon. The connectors (100,300) can include rotatable or stationary pockets, mating members (102,120,302,320) that pivot and/or translate within the coronal plane of the subject to adjust to the positions of the rods, and extension shafts that pivot to adjust for rod angle.
