Low-back pain is the most common reason for x-raying the spine. Unless there has been an injury serious enough to tear ligaments or cause a fracture, initial x-rays should be limited to two views—one from the front and one from the side. Oblique views made from different angles greatly increase radiation exposure and are rarely needed. Chiropractors who routinely obtain a series of x-rays for every new patient may be motivated more by a financial incentive than by concern for the patient’s welfare. When the x-ray series includes every portion of the spine, from the neck to the low back, and there is pain in only one area of the spine, the patient is being subjected to unnecessary radiation.
