Patent ID: 8016860

Claim:
A correction system for a spine having an abnormal curvature, the spine including an upper vertebra, a lower vertebra, and an intermediate vertebra, the intermediate vertebra having an undesired translational and rotational orientation and being located between the upper and lower vertebrae, the system comprising: a rod having a longitudinal axis, a first portion, a second portion, and a medial portion between the first and second portions; a first rod anchor adapted to couple the first portion of the rod to the upper vertebra; a second rod anchor adapted to couple the second portion of the rod to the lower vertebra; and a stabilizer comprising a vertebral anchor adapted to be coupled to the intermediate vertebra on a first side of the spine, a lever member having a first end coupled to the vertebral anchor and a second end spaced apart from the rod and adapted to extend to a second side of the spine opposite the first side of the spine, between the rod and the vertebral anchor, and a force directing member coupled to the second end of the lever member and to the medial portion of the rod, wherein the stabilizer is adjustable to vary a distance between the intermediate vertebra and the medial portion of the rod, wherein the stabilizer is configured to derotate and alter the translational orientation of the intermediate vertebra.
