Luke Madigan, M.D.

Spine Specialist


As the son of an orthopaedic surgeon, Dr. Luke Madigan felt a strong calling toward medicine from an early age. After graduating with a B.S. in biology from Trinity College in Hartford, Connecticut, he earned his medical degree from Thomas Jefferson University in Philadelphia, Pennsylvania. Dr. Madigan remained in Philadelphia for his internship and residency in orthopaedic surgery. He then completed a fellowship in spine surgery at OrthoCarolina Spine Center in Charlotte, North Carolina.

Fascinated by the complexities of the spinal cord and inspired by the motivation and enthusiasm of his chief mentor at a busy spinal cord injury center, Dr. Madigan is pleased to serve at KOC as a spine specialist. He particularly enjoys seeing his patients return to their favorite activities and enjoy life again. His special interests within his field include cervical myelopathy, spinal cord injury and degenerative conditions of the cervical and lumbar spines.

Dr. Madigan is married and has one son. In his leisure time he enjoys running, working out, home improvement projects and spending time with his family.

What patients say about Dr. madigan

  • Thanks to my care at KOC, I can now move about my daily business without sciatic pain, which, at times, was all-encompassing and seemingly unending. I had developed a limp over several years assuming it was continuing issues with other arthritic hot-spots (have had knee and hip replacements as well as foot surgery). Despite therapy, the limp continued, then increasing pain. One month after spinal fusion surgery, I feel like the person I used to be, able to stride normally and without pain. THANK YOU, Dr. Madigan!!!

  • Thanks to my care at KOC, I can enjoy wedding planning with my daughter, explore the caverns of Tennessee with my husband, and enjoy life again all at six weeks post-op! Prior to my surgery on February 23, 2018, tasks such as cleaning, shopping, standing, sitting, and walking were excruciating. I began seeing Dr. Madigan in December of 2017. He ordered an MRI which showed a herniated disc (L4 & L5). I recall during the holiday season of 2017 being unable to enjoy Christmas shopping with my daughter and other festivities due to being unable to stand or walk without pain for even a few moments. Dr. Madigan was not quick to suggest surgery as he and I both saw surgery as the last resort. I had an epidural injection at the end of January and sadly it was not effective. My daughter was engaged on February 10, 2018. This was a time of celebration and I knew I was not going to let my injury ruin my enjoying this moment. During my follow up appointment in February, Dr. Madigan and I spoke about what the next options were and decided surgery was the best option. I cannot thank Dr. Madigan enough for giving me my life back. Now I am able to enjoy the wedding planning with my daughter, explore caves with my husband, and enjoy life.

  • Thanks to my care at KOC, I can look forward to a pain free day. The one thing in life I always knew was that I would never, ever have back surgery. It was my biggest fear and I did everything I could to take care that it would never happen. But as life would have it, that is exactly what I had to have at age 67. For a year I lived with back pain that I tolerated. Then 6 months ago, the pain became unbearable. I could only get some relief lying on the floor. This led me to KOC and Dr. Madigan. Dr. Madigan was informative and straightforward about my situation. He answered every question I had, and did not leave the room until he was sure I had all the knowledge I needed. Two months after my visit, I had a synovial cyst removed and a fusion. I was terrified, but Dr. Madigan's reputation and competent, confident manner allayed my fears. Immediately after the surgery, I was surprised at how little pain there was. Now, just three weeks later, I only take a Tylenol occasionally and am walking 2 miles daily. I know I have a way to go before I can resume the gardening that I love, but I have every confidence now that it will happen. But mostly, I am so relieved to have the pain I was in gone. I am so very thankful for Dr. Madigan and his surgical skill and that he is available to us in this region. Thank you, Dr. Madigan.

  • Thanks to my care at KOC, I can now take a shower standing up and stand up to shave. I was kind of at the end of my rope. I had not been able to get any relief for months. I had been to a previous doctor who had done a fusion on my back a few years ago and through his different nurse practitioners had said there was nothing to be done except therapy. I did therapy and even went to a chiropractor for several months with no relief. Dr. Madigan was very polite and took time to actually take a look and find the problem. He then took the time to discuss the problem with me and my wife, answering questions and explaining the options. He did the surgery and I was able to go home that night. The pain in my legs is gone and for the first time in over six months I can now stand for over 2 minutes. I am 72 years old and Dr. Madigan is one of the best doctors that I have been to. Thank you again Dr. Madigan.

  • Thanks to my care at KOC, I can go back to living the life I was used to with no pain. Thank you to Dr Madigan and his staff. He was there when I needed him.

  • Thanks to my care at KOC, I can walk again with no pain and I can finally sleep on my side. Dr. Madigan is a no beat around the bush doctor. I had back surgery recently after a lengthy journey trying to avoid it. Best decision I ever made. He explained everything to me in layman's terms and all the guidance throughout. Recovery was great and Dr. Madigan puts it out there with regard to progress - It's like - hey you've got to take care of yourself if you want to continue your healing journey. I like him - very personable, warm and friendly - and I'm healed!!! Thanks Dr. Madigan - you are an excellent surgeon and have a superb bed-side manner.

  • Thanks to my care at KOC, I can start to be on the road to recovery from constant neck pain. I had my neck fusion done at the Outpatient Surgery Center next to the West Office. Dr. Madigan was very informative and his knowledge of my procedure gave me confidence that I was at the right place. I’m glad he did my surgery and I would use him again. He is an excellent surgeon.

  • Thanks to my care at KOC, I can walk without pain in my left leg! I had a herniated disc with debris affecting two nerves in my left leg...very painful! After initially seeing Dr. Madigan, I elected to try the less invasive steroid epidural, leaving surgery as the last option. Unfortunately, after experiencing only temporary relief from the second epidural, I had to choose surgery, the last resort, but I had outstanding results! I am back to my life walking my dogs, driving distances, and walking without pain! I am so grateful to Dr. Madigan for giving my life back! I would highly recommend Dr. Madigan, who is conservative, but if surgery is the necessary decision, he got the job done! Thank you, thank you, thank you!

  • Thanks to my care at KOC, I can walk again! All the praise goes to God and Dr. Luke Madigan. Due to spinal stenosis and rheumatoid arthritis, I had become almost bedridden. Each step caused severe pain. Then Dr. Luke Madigan preformed a lumbar fusion L3 to L5 on my spine on May 16, 2016. I found him to be compassionate and knowledgeable. He took the time to answer all of my questions. He even allowed me to pray with him prior to my surgery. My recovery went as expected. The first two weeks were very painful, then my body began to recover. Now six months out, I have no pain in my lower back. I was concerned about becoming addicted to pain medication, but Dr. Madigan keeps a close eye on that and only prescribes what you need, reducing the dosage as quickly as possible. I was so satisfied with Dr. Madigan that when my husband needed back surgery three weeks ago, there was no question who would be preforming the surgery. My husband is also recovering extremely well. He had a herniated disc. I would highly recommend Dr. Luke Madigan. You will not find anyone better. Thank you for giving me my life back Dr. Madigan!

  • Thanks to my care at KOC, I can turn my head and neck without severe pain. I have degenerative disc disease that gets increasingly worse every year. Dr. Luke Madigan was very understanding and willing to help me get relief. He was very easy to talk to and explained what he thought would help me. I was very happy to find someone that I feel I can call on and depend on to help me in the future. I would highly recommend Dr. Madigan.
