摘要

A spinal device and associated method are provided for spreading of first and second vertebral elements, each of the first and second vertebral elements having a circumferential surface defining a vertebral body and a pedicle having a pedicle root portion adjacent the circumferential surface. The device includes a first end member having at least one surface adapted to conform to at least one of the circumferential surface and the pedicle root portion of the first vertebral element, and a second end member having at least one surface adapted to conform to at least one of the circumferential surface and the pedicle root portion of the second vertebral element. The device further includes a resilient member extending between the first and second end members and being adapted to exert a force against the first and second vertebral elements.
