Abstract

A retractor includes a first wall extending from the base. The first wall has a longitudinal axis and extends between a first end and a second end. The first wall includes at least a portion of a longitudinal cavity. A rotatable shaft includes an outer surface that defines a groove. At least a portion of the shaft is disposed in the longitudinal cavity. A blade is disposed for movement along the longitudinal cavity. A post is connected with the blade and is disposed with the groove such that rotation of the shaft causes axial translation of the blade relative to the first wall between a first orientation and a second orientation. Methods of use are disclosed.
