Abstract
A surgical retractor assembly is provided having a frame that releasably couples two retractor blades. The retractor blades are coupled to the frame via a pair of mobile carriages that engage a track on the frame. A third retractor blade is configured to be independent of the frame with the first two retractor blades. The independent blade may be fixably positionable in the patient by a direct coupling to a rigid table mount. The retractor assembly may be utilized for creating anterior access to spinal target site while the patient is oriented in the lateral decubitus position.

A method comprising:
- positioning a patient on a table in a lateral decubitus position;
- forming an incision in the patient;
- accessing the patient's retroperitoneal space;
- advancing a lateral retractor blade into the retroperitoneal space;
- advancing a cranial retractor blade into the retroperitoneal space;
- advancing first and second carriages into a track of an arcuate frame;
- disposing the frame proximate the incision;
- coupling a first rigid table mount to the frame;
- coupling a lateral retractor assembly to the frame by disposing a lateral retractor post of the lateral retractor assembly in a blade holder of the first carriage;
- coupling a cranial retractor assembly to the frame by disposing a cranial retractor post of the cranial retractor assembly in a blade holder of the second carriage;
- through a corridor defined in part by the lateral retractor blade and the cranial retractor blade, preparing a target disc space;
- placing an implant in the target disc space;
- and
- closing the incision.
