SPINAL CORRECTION ADJUSTMENT SYSTEMS AND METHODS

摘要

A system provides for lateral translational corrective force(s) and/or derotational corrective force(s) on a spinal column and includes highly adaptive hardware for connecting the system to the spinal column, where the hardware facilitates a more natural range of motion within pre-selected limits and application of such lateral translational and/or derotational corrective force(s). The upper and lower vertebral segments retain freedom of movement while an apical or restricted segment is restricted from relative vertebral movement. A central segment controls primary rod roll while the rod is free to change in pitch, yaw and roll at the upper (superior) and lower (inferior) segments.

主权项

1. A coupler for an implantable spinal correction system, the coupler comprising:
a first connector configured for securement to a first stabilizing member; a second connector configured for securement to at least one of a vertebral anchor or a second stabilizing member; a first slide member having a central bore and being connected to the first connector; a second slide member having a central bore and being connected to the second connector and telescopically received within the central bore of the first slide member; a drive member extending through the central bores of the first and second slide members; an actuator coupled with the drive member such that rotation of the actuator causes rotation of the drive member resulting in relative, longitudinal movement between the first and second slide members.
