I am 4 weeks past my surgery where my surgeon used the x-stop spacer to correct my L-4 L-5 spinal stenonsis and constant sciatica in my right hip, leg and foot. I am doing wonderfully!! And NO MORE PAIN in my hip or down my leg. I actually have toes on my right foot now that I can feel again. I can walk without constant pain and I am off all pain meds for the first time in several years! I was only in surgery for 45 min. under general anesth. and was released from the hospital the same day to recover at home. The 4-5 inch incision was painful and my activity was severly limited the first few days, (my husband had to help me even turn in bed) but with the support of my back brace and just being careful, I slowly got better each day. I still can not lift anything over 10-15 lbs. and no twisting, bending straight over and other such movements, but I am walking 30-40 minuets a day now and only "pressure" like pain in my incision area of my back if I am on my feet too long now which is getting less each day. The sciactic type pain is completely gone. My doctor says I will need to be very careful for several more months, but nothing like the time it takes to heal from the standard laminectomy/ fusion type surgery. I would suggest that if you have this option, take it.
