Motion-sparing spinal surgery, using things like the Dynesys system have become somewhat popular with some patients and physicians.
This young woman had a Dynesys system put in her lumbosacral spine done elsewhere, below a previous Harrington Rod instrumentation and fusion. She did not get any relief, and now her pain is much worse.
She has failed conservative therapy, and now we are discussing fixing her flat back syndrome, spinal stenosis, and spondylosis and disc degeneration below her previous Harrington Rod fusion by doing an anterior L45 and L5S1 Anterior Lumbar Interbody Fusion (ALIF), followed by a posterior L2-S1-Ilium revision instrumentation and fusion with removal of Dynesys system, and multilevel lumbar laminectomy to take the pressure off the nerves.
