From back surgery fusion from L4-S1 now I have right Foot Drop. Can you help me understand WHY? What causes Foot Drop? What causes bilateral leg weakness and neuropathy bilateral from knees to feet? Never had any pain like I have now.Dr. CorenmanModeratorFebruary 28, 2012 at 10:36 pmPost count: 3545
Foot drop originates from L5 or L4 nerve dysfunction. If you have new onset foot drop after a fusion of the L4- S1 levels, a new MRI is warranted to look for the cause. The cause could be from nerve root stretch, compression of the root from a screw or a cage compressing the root.
Bilateral leg weakness can be caused by many disorders including metabolic and the neck. Peripheral neuropathy is normally caused by a long standing disorder such as diabetes.
You have new onset pain since surgery. What was the original pain (back or leg) and what was the surgery performed for?

My original pain came from the lower back, surgery for herninated disc L4-5-S1 not sure which one has the hernation not long standing. My symptoms started directly after my fusion. I do not have Diabetes. I did have the hardware taken out 1 year later. It was said, one screw was too far in the cortex of the spine. When the hardware was removed It seemed my weakness and neuropathy got worse the foot drop stayed the same. Never did suffer from leg pain, bowel and bladder problems, neuropathy pain, leg weakness and the electrically shock pain at times is almost more than a human can withstand… Thank you for talking to me.Dr. CorenmanModeratorMarch 5, 2012 at 9:21 amPost count: 3545
Apparently you had a post-operative workup and the hardware was then removed after the fusion became solid. If there is no residual compression of the nerve, you have chronic radiculopathy (see website). With continued severe pain, you might be a candidate for a spinal cord stimulator.
I have not as of yet written a section for spinal cord stimulation. Do a Google search for this treatment and read about it. Medications like Lyrica or Neurontin might be helpful. Find a chronic pain doctor to help you cope with the pain.

I feel there is a nerve being compressed in the upper buttock now, because when I turn over it bits me. I feel its swollen in this area and hurts like heck. When it gets bad like it is now I get hot pain to the right foot and ankle area. I tried the stimulator it aggravated the nerves worse. I am on the highest does of gabapentin, you can take. I have a pain management doctor. Now the nerve damage is done I need a doctor who knows how to give me the right pain medications for the pain that feels like electricity hot and extremely painful (no amount of pain medication works with the type of pain). Nobody knows what to do with me…maybe they just don’t know how? All I know is I was not like this before surgery. What is residual compression? Thank you for your suggestions.Dr. CorenmanModeratorMarch 6, 2012 at 5:03 amPost count: 3545
You note you “tried a stimulator”. Was this a formal trial of a spinal cord stimulator- where under sedation in an operating room, s surgeon using fluoroscopy (real-time X-ray), placed a set of leads or paddles onto the spine cord? Or- was it a set of pads placed onto the skin over the painful area (a TENS unit)?
Residual compression should be revealed by an MRI or a CT myelogram. What did the radiologist say regarding the post-operative MRI?
