TETHERING DEVICES AND METHODS TO TREAT A SPINAL DEFORMITY

摘要

The present application is directed to tethering systems that provide a corrective force to one or more vertebral members. The tethering systems may include an elongated member with first and second sections. The sections are displaceable relative to each other to increase a length of the elongated member. The first section may be attached to a first vertebral member, and a second section may be attached to a second vertebral member. At least one tether may be attached to the elongated member. The tether may include a length to be attached to the first and second sections, and to a third vertebral member that is positioned between and laterally offset from the first and second vertebral members. The length of the elongated member may increase thus causing the tether to apply a corrective force to the third vertebral member.
