Abstract

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 anchor (20) further includes screw means (50 and 52) for embedding into the vertebral body (90) upon rotation of the platform (24). The platform (24) includes at least one passage (44) extending transversely through the platform. The passage (44) receives 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.
