Abstract:
1. A system for growth directed correction of a spine via apical vertebral control, the system comprising: a first rod extending from a first end to a second end, the first rod having a central longitudinal axis that defines a first correction axis, the first rod being adapted to be secured to a first vertebra proximate the first end of the first rod; a second rod extending from a first end to a second end and being adapted to be secured to a second vertebra proximate the first end of the second rod; a hosting connector assembly adapted to combine with the first rod and the second rod, the hosting connector having a central longitudinal axis that defines a second correction axis laterally offset from the first and second rods that extends adjacent the spine, the hosting connector assembly including: an intermediate connector that is secured to the hosting connector assembly and extends in a substantially transverse direction away from the first and second correction axes of the system, the intermediate connector being adapted to be secured to a single vertebra located between the first and second vertebrae to selectively lock a distance between the intermediate vertebra and the correction axis; a first stop feature positioned between the first and second ends of the first rod and to limit axial travel of the first rod through the first connector in a first direction of travel; and a second stop feature positioned between the first and second ends of the second rod and to limit axial travel of the second rod through the second connector in a second direction of travel that is generally opposite to the first direction of travel, the first and second stops features establishing a minimum overall system length by limiting sliding of the first and second rods toward one another.
