    摘要: A cam spreader having a substantially rigid body with a proximal end defining a handle and a distal end defining a cam. The cam has at least a first lobe, the first lobe having an outer surface in a first quadrant of the cam as viewed in cross section along a longitudinal central axis of the body. At least a portion of the outer surface, or profile, of the curve is mathematically driven and produces a constant incremental lift.

    摘要: An implant for insertion into a patient includes a superior surface disposed at a first end of the implant and an inferior surface disposed at a second, opposite end of the implant. The superior and inferior surfaces of the implant are constructed with curvatures that approximately match the morphology of vertebral endplates. The inferior surface and superior surface may include the same or different radii of curvature within the coronal and sagittal planes. The inferior surface and superior surface may be defined by spherical radii. The radius of the superior surface may be about 60 percent to 74 percent of the radius of the inferior surface.

    摘要: A method of performing a surgical procedure at an anatomical location in a patient is disclosed. An incision is made in the patient to provide access to an anatomical element. A pressure measurement device may then be inserted into a predetermined area of tissue surrounding the anatomical element. Tissue surrounding the anatomical element may then be retracted with a retractor to expose the anatomical element. A pressure reading from the pressure measurement device may then be obtained that is indicative of an amount of pressure experienced by the predetermined area of tissue as a result of the retraction.
