MULTI-DIRECTIONAL SPINAL STABILIZATION SYSTEMS AND METHODS

摘要

Systems and methods for multi-directional stabilization of a spinal column segment (10) are provided. The systems (30, 130, 230, 330, 520) include one or more motion preserving constructs (32, 132, 230, 330, 530) that are engaged to adjacent vertebrae (12, 14) and extend trans-axially between the vertebrae (12, 14) obliquely to the central axis (11) of the spinal column. The systems permit motion of at least a portion of a vertebral level while providing stabilization at least when tensioned. Systems that provide stabilization in compression are also contemplated.
