Abstract
A system and a method for providing minimally invasive access to the spine of a patient and implanting spinal stabilization devices. The system utilizes one or more post-type access devices. The post-type access device includes a cage with an aperture and two or more posts extending from the cage and being removably attached to the cage. The posts are supported at the top of the access device by a support ring structure. A pedicle screw is inserted into the access device and through the cage aperture and the screw-access device assembly is inserted into an opening of the patient's body. The base aperture is dimensioned to securely support the head of the screw. Side openings between the posts allow the insertion and placement of stabilization devices, such as rods, wires, or plates from almost any direction.
