About Us

Dr. Kim is a fellowship-trained spine surgeon in Manhattan who has presented nationally and internationally on spinal deformity surgery, cervical spine surgery, cervical disc replacements, and lumbar spine surgery. Because he trained with both orthopaedic and neurosurgical spine surgeons, he has an interdisciplinary approach to spine care. Modern spine care should be comprehensive and multidisciplinary. A successful outcome involves a team approach that comprises physiatrists, physical therapists, anesthesiologists, neurologists, internists, endocrinologists, radiologists, rheumatologists, pulmonologists, and pediatricians. He believes that all non-surgical avenues should be explored and trialed before surgery. Lastly, if and when surgery is necessary, Dr. Kim’s goal is to customize the spine surgery for the patient utilizing modern and minimally invasive techniques.

The Orthopaedic Center at Mount Sinai West

Back or neck pain can be debilitating, and affect many aspects of your daily life. Mount Sinai West spine experts have vast experience treating the full spectrum of conditions affecting the spine, ranging from your lower back (lumbar spine) to your neck (cervical spine). Many spine conditions can be treated non-surgically, but when surgery is the best option to treat your condition—we emphasize minimally invasive spine procedures whenever possible. We also regularly perform complex reconstructions to treat severe spinal deformities and scoliosis.

For non-surgical spine care, we offer an interventional spine physiatrist with expertise in pain management, sports medicine and osteopathic manipulative medicine.

Mount Sinai West also offers pediatric spine care including the treatment of scoliosis.

Because modern spine care is multidisciplinary, our team meets on a weekly basis to discuss complex spinal cases. It offers a platform to discuss an optimal and customized treatment plan for each and every surgical patient.

If you need spine surgery, you can choose Mount Sinai West with confidence.
