Abstract
There is disclosed a retractor system to facilitate surgical access to an intervertebral disc between an inferior vertebral body and a superior vertebral body. In an embodiment, the retractor system includes an elongate member having an anchor to attach to a pedicle of an inferior vertebral body with respect to an intervertebral disc. A retractor body has a collar to attach to the elongate member, slides coupled to the retractor body, and a pair of blades mounted to the slides. The blades have a proximal end and a distal end, a distance between the proximal end and the distal end of each one of the blades configured for displacing tissue for access to an intervertebral disc. An attachment portion is adjacent the proximal end of each one of the blades for attaching one of the slides thereto. Geometry of the blade end conforms to anatomy surrounding the pedicle.
