Abstract
Systems and methods are described for correcting sagittal imbalance in a spine including instruments for performing the controlled release of the anterior longitudinal ligament through a lateral access corridor and hyper-lordotic lateral implants.
Claims17
A method for correcting sagittal imbalance of a lumbar spine, comprising the steps of:
- a) creating a lateral operative corridor to access a targeted spinal disc via a lateral approach by inserting an access system along a lateral, trans-psoas path to the targeted spinal disc;
- b) inserting a cutting device through the lateral operative corridor and severing the Anterior Longitudinal Ligament (ALL);
- c) connecting an insertion instrument to a first retractor blade forming a portion of a border of the lateral operative corridor, the insertion instrument having an implant for positioning between the adjacent vertebral bodies bordering the targeted disc coupled thereto;
- and
- d) advancing the insertion instrument along the first retractor blade to position the implant between the adjacent vertebral bodies.

A method for correcting sagittal imbalance of a lumbar spine, comprising:
- creating a lateral operative corridor to access a targeted spinal disc by inserting an access system along a lateral, trans-psoas path extending into a retroperitoneal space and through a psoas muscle to the targeted spinal disc, wherein the access system comprises at least one dilator and a retractor that slides over the at least one dilator in a first configuration, and wherein the retractor thereafter adjusts to a second configuration to form the lateral operative corridor;
- inserting a cutting device through the lateral operative corridor and severing the Anterior Longitudinal Ligament (ALL);
- inserting an insertion instrument into the lateral operative corridor, the insertion instrument having an implant coupled thereto for positioning between the adjacent vertebral bodies bordering the targeted disc;
- and
- advancing the insertion instrument through the lateral operative corridor to position the implant between the adjacent vertebral bodies.
