About Spinal Stenosis
Spinal stenosis is a condition that is characterized by a narrowing of the spinal canal. The narrowing can occur in a single location or multiple locations up and down the spinal column. At any of these areas, the narrowing can cause pain and loss of sensation or compromise muscle control, depending upon the amount of narrowing. While cervical stenosis is associated with pain in the neck, lumbar stenosis can cause significant leg pain. When the stenosis occurs in the lumbar region of the spine, pinching the nerve that runs down the leg to the foot, it can create a condition called foot drop. This condition gets its name because patients with this issue cannot flex their foot upward and hold it. This lack of muscle control means the patient’s gait is affected. Dr. Kendall Carll is a board-certified spine surgeon who has been practicing for more than 15 years in the North Texas area. Using his experience, he can help patients identify possible causes of spinal stenosis and investigate options to eliminate the problem or help patients effectively cope with symptoms.
"I recently experienced a pinched nerve that severely affected my ability to use my right hand. I contacted Dr. Carll who immediately went to work on my behalf. Knowing that this was a time sensitive situation Dr. Carll went out of his way to ensure that I received the appropriate MRIs, CAT scans, and nerve studies to properly diagnose my situation. After reviewing all the test Dr. Carll exhibited true professionalism and integrity by referring me out to Dr. Patty Young (I am so thankful for your referral) who specialized in the surgery that I would need. Dr. Carll could’ve chosen to operate because I had several degenerative disc, however he chose ethics over profit. Dr. Carll is a true professional that will put your health over profit! When it comes to your health there’s nothing more important than having a doctor that you can trust to be professional and ethical. Thank you Dr. Carll for providing me with both!"- K.H. / Google / Aug 29, 2018
"My name is Mark Walter. Doctor Carll and his staff are simply the best when it comes to spine and back care, bar none ! Ive had a total of 6 spine surgeries to date. My first one was done by a different doctor and it failed. I found Dr Carll after exhaustive research and countless inital consultations with numerous other doctors and I'm so glad I found him. He has since then performed five additional spine surgeries on me. I was badly screwed up to say the least and he literally gave me my life back. I highly recommend him to everyone including my own family members, one of which he also done surgery on and like me she was totally thrilled with him and the results. His staff are hands down the best in the business and the only team that Ive NEVER had a single complaint or issue with !!! This man knows his stuff and sets the standard other doctors and surgeons only dream of achieving. No games and no lies. Just kindness, honesty, and most importantly, he treats people like his friends and neighbors and not an ATM machine like so many doctors do now days. Give his office a call. Its the best thing you will ever do for your spine & your own peace of mind."- F. / Google / Nov 07, 2019
"Dr Carll was a lifesaver for me! I fought the back pain from a pinched/herniated sciatic nerve for 7 months. I tried everything from PT, chiropractic, spinal decompression, antigravity table, ibuprofen and more ibuprofen and steroids. Eventually, the pain was so unbearable that I could not sit through a meal or even drive. I finally gave up avoiding surgery and went to Dr Carll. I had minimally invasive microdisctectomy and the results were excellent. A few months of rehab later and I’ve got my life back. I’m so glad I saw Dr. Carll! He was so caring and explained everything thoroughly, including what to expect after surgery. His staff was just as wonderful and caring. I’d go back to him in a heartbeat. I’m very grateful for his skilled hands. God bless them."- M.J. / Healthgrades / Oct 15, 2019
"Dr. Carll is THE BEST!!! I had to have an A-lift spinal fusion and never before have I seen such a caring doctor and staff. They held my hand through my fears were actually there for me and more throughout the process. I don't believe there is a more caring, more compassionate doctor than Dr. Carll. Thanks to him and his amazing abilities I can feel my right leg again and now live without pain. I will forever be grateful to this office and Dr. Carll for being there for me as a person and as a patient.-Nicole Baucum"- Anonymous / Healthgrades / May 17, 2019

The spinal vertebrae are shaped with an opening in the middle, so that when they stack on top of one another, they create a central canal for the spinal cord. Spinal nerve branches extend from the central spinal cord, jutting through gaps in between each of the stacked spinal vertebrae and extending to the left and right of the spine into the body. Spinal stenosis is a narrowing of the channel at the center of the spinal column. This narrowing is most often caused by degenerative disc disease or inflammation associated with arthritis. The inflammation can also be caused by bone spurs that may form on an individual vertebra, and these bone spurs can intrude into the spinal canal and touch or squeeze the spinal cord or the individual nerve branches. While some individuals may be born with congenital stenosis, inflammation from previous back surgeries can also cause some degree of stenosis.
Symptoms of spinal stenosis may vary depending on the location of the conditions, but they commonly include:
- Intervals of pain in the affected area
- Pain during strenuous activity or exercise
- Relief of pain upon sitting or lying down
Similarly, the symptoms of foot drop that can develop through lumbar spinal stenosis include the inability to lift the toes and drag the feet or toes when walking, which causes an abnormal gait.
To validate a diagnosis of spinal stenosis that may be causing foot drop, Dr. Carll will likely order an x-ray to rule out other problems, followed by an MRI or CT scan with myelogram to look at the soft tissues surrounding the spine and the nerves. For certain types of spinal stenosis, Dr. Carll may also suggest a selective nerve root block, which involves injecting an anesthetic into the suspect nerve to evaluate the level of relief.
Most cases of spinal stenosis and/or foot drop may be treated with a combination of specialized exercise, physical therapy, bracing to ensure the correct foot posture while walking, and spinal injections or oral medications to reduce inflammation that might be causing the stenosis. In some cases, Dr. Carll may also prescribe pain medications and muscle relaxers.
For severe cases of spinal stenosis, Dr. Carll may recommend surgery to remove a small section of bone from the vertebra near where the spinal cord is being compressed. By removing a section of vertebral bone, the surgeon gives the spinal cord more room. Once that part of the procedure is complete and within the same surgery, the surgeon may fuse the affected vertebra to the vertebrae immediately above and below to stabilize that section of the spine. This will be done by screwing metal strips, one on the left side of the vertebrae and one on the right, to fasten all three vertebrae together. A bone graft is typically placed over the screws and strips. Eventually, new bone will grow over the screws and create a single solid, stable bone structure.
If a herniated disc is the cause of the spinal stenosis, a common solution is to remove the affected disc. In some cases, the surgeon may insert a metallic spacer or bone material to keep the vertebrae separated. Typically, these procedures are performed using minimally invasive techniques. Like the procedure above, the removal of the intervertebral disc is usually accompanied by a spinal fusion procedure.
