1. A spinal implant system comprising:
a superior attachment rod coupled to, and articulating with respect to, a roller housing, wherein said superior attachment rod passes through a hole formed in said roller housing, said hole being larger than an outer diameter of said superior attachment rod such that said superior attachment rod can tilt and radially translate with respect to said hole;
an inferior cross bar member coupled to said roller housing;
an inferior attachment rod coupled to said inferior cross bar member, wherein a flexure assembly is mounted on said superior attachment rod and said hole is larger than an outer diameter of said flexure assembly such that there is a gap between the inner diameter of said hole and the outer diameter of said flexure assembly so that said superior attachment rod and said flexure assembly are not clamped in said hole but instead tilt and radially translate with respect to said hole; and
wherein said inferior attachment rod comprises at least two inferior attachment rods which are coupled to said inferior cross bar member with a common swivel joint and a telescoping portion, wherein side-to-side movement of said telescoping portion determines a side-to-side position of said inferior attachment rods, and wherein said inferior attachment rods are rotatable about a longitudinal axis of said telescoping portion.
