The invention relates to a flexible spine stabilization and/or vertebral replacement system and having one or more flexible segments within a spinal element. The flexibility is created through the use of at least one circumferential slot formed in the spinal element. One or more fasteners are connected to the distal and proximal attachments and secured to the vertebra. The spinal element can have an elastomeric material in any or all of the following combinations: filling at least one of the at least one slot at least a portion of the inside core encompass at least a portion of the exterior diameter. Vertebral replacement is achieved by securing the spinal element to healthy inferior and superior vertebra through use of securing members.
