Lonner is internationally recognized for his expertise in treating pediatric scoliosis, adult scoliosis, kyphosis, and complex spinal deformities. With more than 20 years of experience, he has dedicated his career to advancing scoliosis care through innovative surgical techniques, groundbreaking research, and compassionate, patient-centered treatment.
I had one of the most advance cases of Scoliosis with a 89 degree curve. A surgeon tried to correct it but was unsuccessful and almost paralyze me in the process. When I came out of surgery I could not walk and had no felling in my left leg. After much therapy I recovered and was able to walk. But I was advised never to have surgery again. Problem was I was extremely uncomfortable living in my body. All my internal organs were being crushed. I went to many other surgeons to see if they could help. They all said no, they said absolutely not. I was too risky. Then one of the surgeons said to me there is only 2 doctors in the world that could touch you, one of them is in another country and the other is doctor Lonner. I met doctor Lonner, and he made it seems so easy to do my surgery. I was shocked. I quickly scheduled the surgery in fear that he would change his mind, the surgery was a huge success. I praise God every day. Biggest blessing of my life. ~ Google
