Abstract
A spinal construct includes at least one tether extending between a first end connectable with a first fastener connected with spinal tissue and a second end connectable with a second fastener connected with spinal tissue. The at least one tether has a tension between the fasteners. A ratchet is engagable with the at least one tether to adjust the tension. Systems and methods are disclosed.
Claims17
A spinal construct comprising:
- at least one tether extending between a first end connectable with a first fastener connected with spinal tissue and a second end connectable with a second fastener connected with spinal tissue, the at least one tether having a tension between the fasteners;
- and
- a ratchet engageable with the at least one tether to adjust the tension, the ratchet includes a rotatable reel configured for rotation in two directions to adjust the tension, the rotatable reel being axially movable between a first configuration in which the reel is rotatable relative to the ratchet and a second configuration in which rotation of the reel is resisted.
A spinal construct comprising:
- a fastener including a ratchet having a reel engageable with an intermediate portion of a tether having a tension between ends thereof,
- wherein the reel is rotatable in two directions relative to the ratchet to adjust the tension, and wherein the reel is axially movable between a first configuration such that the reel is rotatable relative to the ratchet and a second configuration such that the rotation of the reel is resisted.
A method of treating a spine disorder, the method comprising the steps of:
- providing at least one tether extending between a first end connected with a first fastener and a second end connected with a second fastener, the at least one tether having a tension between the fasteners;
- providing a ratchet for connection with an intermediate portion of the at least one tether;
- engaging the first fastener with a first costo-vertebral surface and engaging the second fastener with a second costo-vertebral surface;
- and
- engaging the ratchet and a reel to rotate the reel in two directions to selectively adjust the tension, wherein the step of engaging the ratchet comprises axially translating the reel between a first configuration such that the reel is rotatable relative to the ratchet and a second configuration such that rotation of the reel is resisted.
