The traditional treatment was an open laminectomy. Unfortunately this causes significant muscle and bone damage and may lead to a weak back, worse back pain and instability (the back falling apart), never mind the significant scar tissue. Today there are new minimally invasive options for spinal stenosis including minimally invasive tubular decompression (METRx) , X-Stop, spinal clamp and MILD procedure. There will soon be new endoscopic decompression procedures developed for spinal stenosis. Good Luck!
