Post-operative Xray

The patient was treated with posterior decompression and release through a PLIF approach, spondylolisthesis reduction with pedicle screw construct L4-S1, and cantilever reduction and compression to restore lordosis.  The provisional instrumentation at L4 was then removed allowing fusion of only the L5/S1 segment.  Postop xrays demonstrate reduction of spondylolisthesis and restoration of sagittal alignment with clinical resolution of back pain, leg pain, and foot weakness.
