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.

Surgical retractor and method of use

A retractor assembly for surgery in a patient includes at least one retractor member removably engageable to a support member. The retractor assembly includes a housing assembly engaged to the support member and to an arm that extends from a retraction portion of the retractor member. A drive mechanism in the housing assembly is coupled to the retractor member and is operable to rotate the retraction portion of the retractor member relative to the support member to a desired angular orientation.

Retractor assemblies with blade drive mechanisms

Vertebral column manipulation systems include spinal derotation instrumentation to affect one or more derotation maneuvers on a scoliotic spine or on a spine having one or more displaced, misaligned or curved vertebral levels. Derotation instrumentation is attached to at least one vertebral body, with the instrumentation including at least two elongated extensions mounted to and extending proximally from the at least one vertebral body. A linking assembly extends between and links proximal ends of the extensions to one another. The linking assembly includes first and second mounting assemblies movably engaged to an elongate link member extending transversely to the extensions. Each of the mounting assemblies includes a movable joint for receiving the proximal end of a respective one of the extensions and a cam assembly for securing the mounting assembly in position relative to the link member and to fix the joint around the extension.
