An apparatus (10) for correcting spinal deformity comprises at least one anchor (20) for implantation into a vertebral body (90). The anchor (20) includes a platform (24) having a first surface (38) for facing the vertebral body (90). The platform (24) includes a tunnel (40) and at least one passage (44) extending through the platform. The passage (44) extends transverse to and intersects the tunnel (40). The anchor (20) includes screw means (50, 52) for embedding into the vertebral body (90). A removable rod (70) extends into the tunnel (40) and has at least one opening (72) for receiving a cable (120) connected with another anchor (20) in another vertebral body (92). The cable (120) is tensioned to cause relative movement between the vertebral bodies (90 and 92) and thereby correct the spinal deformity. Additional cables (150, 170) may be connected to the anchors (20) and tensioned to achieve correction in multiple planes. |
