Dr. Segal strongly believes that back surgery is a last resort and should be avoided whenever possible. He has seen many, many patients over the years that have been told they may need surgery. Most have them have recovered under his care and were able to avoid surgery and the risks that are associated with it.
Mild to moderate disc herniations can usually be treated conservatively with stretching, exercise therapy and chiropractic care. More advanced cases will often require some form of spinal decompression, such as traction or mechanical decompression, in conjuction with chiropractic care.
Occasionally, a herniation may be severe enough to warrant surgical intervention. These cases are usually reserved as a last resort when other forms of therapy have failed to relieve pain, or if there is significant compression of the spinal cord or nerves.
