Case 3. The preoperative and postoperative lumbar radiographs show effective correction of both the lateral L4–5 listhesis and the 40° lumbar scoliosis using 3-level XLIF and L2–5 posterior instrumentation and fusion. One should note the convergence, or “pointing,” of the scoliotic disk spaces toward a confined area on the concave flank—this provides for a more minimally invasive surgery than the historical convex “extensile” approach.
