Device and method for correcting a spinal deformity
A method for correcting a spinal deformity is provided. A spinal implant for correcting a spinal deformity includes a multipoint connector that connects to at least one vertebra of a spine at a plurality of locations and a force directing device that applies a force to the vertebra through the multipoint connector. The force directing device may include a rod which extends generally along an axis of the spine and a force directing member which is adjustably coupled to both the rod and the multipoint connector and which applies a corrective force to the at least one vertebra.
