About
Qasim Zaidi, MD is a fellowship-trained orthopedic surgeon and spine specialist practicing in St. Louis, MO.
Dr. Zaidi completed his orthopedic surgery training at Loma Linda University Medical Center in Loma Linda, CA. Following his residency, he completed a specialized, high-volume fellowship in spine surgery that focused on degenerative conditions, minimally invasive surgery (MIS), advanced image-guided navigation and robotic surgery at New England Baptist Hospital in Boston, MA.
Dr. Zaidi's expertise is in motion preservation using artificial cervical disc replacement, performing same day/outpatient surgery and using multi-modality pain management to relieve discomfort due to inflammation and nerve irritation. He specializes in cervical (neck) and lumbar (lower back) surgery and commonly performs procedures such as lumbar microdiscectomy, laminectomy, ACDF and artificial disc replacement.
"My goal is to utilize cutting edge technology and state-of-the-art tools to diagnose and treat your neck and lower back, in addition to the shoulder, arm or leg pain that your spine may be causing," Dr. Zaidi says. "These tools include specialized physical therapy programs, dynamic x-rays, magnetic resonance imaging and/or computed tomography, electromyography and/or nerve conduction velocity testing, epidural steroid injections, selective nerve root blocks, medial branch blocks and intra-articular facet injections. After exhausting all of these non-operative techniques surgery may be a good option for you. I will determine a unique surgical plan to treat your pain while using minimally invasive techniques at every step."
Outside of work Dr. Zaidi enjoys playing tennis and basketball with his son. He is an avid car enthusiast and also enjoys tropical gardening.
Dr. Zaidi accepts all major insurances. For more information, please visit our Insurance page.
