Abstract
Methods of correcting a spinal deformity, including securing a first rod on a first side of a spine, securing an anchor on a second side of a spine, securing a lateral coupling between the rod and the anchor, translating and derotating the spine to correct the spinal deformity by adjusting an effective length of the lateral coupling, and securing a second rod on a second side of the spine to provide secondary stabilization to the spine.
Claims17
A system for correcting a spinal deformity, the system comprising:
- a first rod configured to be secured on a first side of a spine;
- a transverse anchor configured to be secured on a second side of the spine;
- and
- a lateral coupling secured between the first rod and the transverse anchor, the lateral coupling configured to derotate and translate the spine,
- wherein the transverse anchor includes a head defining a receptacle for receiving a second rod, the receptacle defining a central axis extending in a direction transverse from the lateral coupling, the second rod configured to be secured on the second side of the spine, a fixation member configured to secure the head of the transverse anchor to the second side of the spine, and an arm extending from the head configured to extend from the second side of the spine to the first side of the spine.
