Spinal correction system

Abstract

A spinal correction system comprises a first member defining a longitudinal axis and including an inner surface that defines a first cavity and a second cavity. A second member defines a longitudinal axis and includes an inner surface that defines a first cavity and a second cavity. The members are connected along a first axis disposed in substantially parallel relation to the longitudinal axes. At least one first implant support is configured for disposal within the first cavities. At least one second implant support is configured for disposal within the second cavities. The members are rotatable about the first axis to space apart the members such that the inner surfaces forcibly engage the supports in releasable fixation. Methods of use are disclosed.
