Doctor 'Intervenes' to Help Aching Backs

Dr. Ben Humpherys specializes in pain relief of the spine.

He’s an expert in “pain intervention” of the spine’s nerves, discs and joints. He understands where to target injections designed to deliver pain relief to all the sore spots — you know, the aching areas we identify with such unpleasant adjectives as inflamed, swollen, pinching, bulging and slipped.

These injections of steroids and numbing agents can slow or block chronic pain for months and defer or prevent the need for surgery.

“People are in pain,” he says, “and we try to intervene.”

And when you’re dealing with such a tricky area as the spine, you want a physician who’s practiced in providing successful injections. That’s because an epidural injection, for instance, offers a target of only a few millimeters. Dr. Humpherys estimates he’s provided more than 12,000 injections over his career.

Dr. Humpherys and his physician assistant, Greg Rasmussen, specialize in spine pain that has eroded an individual’s ability to perform daily activities. Typically, that’s back pain, headache or neck pain. Nerve damage in the spine also shows itself in an extremity, such as numbness in the leg or weakness in the arm.

Other patients have neck pain, says Dr. Humpherys, adding, “Car accidents are one of the most common reasons I see people for neck problems.”

Referred by primary-care doctor

The first stop for a patient who has back pain should be to that individual’s primary care doctor, who will oversee a course of conservative treatments. If those treatments fail, or if the individual develops nerve damage problems, Dr. Humpherys’ services are often recommended.

The physician’s first step with new patients is to diagnose the reason for the back and nerve pain, based on history and often an MRI. “We look at the nerves, the discs, the joints, the vertebrae, the spinal cord,” he said. “We look at everything.”

Low-back pain is caused by a number of factors — a disc that is herniated or torn, bone growths, a nerve pinched by inflammation, or stenosis (a narrowing of the spinal column). Often, the pain is caused by arthritis in the spine’s joints.

Live x-ray guides injection

The most common procedure Dr. Humpherys performs in an epidural steroid injection. The injection of steroid into the spine’s epidural space provides a powerful anti-inflammatory that helps calm the pinched nerve and the pain from an inflamed disc when there’s been injury. Steroid use must be regulated, he adds, because of such possible side effects as osteoporosis.

The injection needle is guided by what could be described as a “live” x-ray. The large machine, called a fluoroscope, allows the physician to “see the structures of the spine and where the needle is in relation to the anatomy,” Dr. Humpherys said.

Injection for arthritis pain relief

Another common treatment is radiofrequency nerve ablation, often used in place of steroids to alleviate arthritis pain. This procedure uses a special needle to burn the nerve, interrupting its signal to the brain. “We’ve learned that burning or stunning the nerve makes the effect last longer than steroid injections,” said Dr. Humpherys.

Dr. Humpherys explains that injections and other interventional methods are management strategies to help those with pain improve their limitations and better perform the activities of daily life.

Tanner's Two Physiatrists:

*Dr. Humpherys focuses on the spine

*Dr. Derr on extremities as well as the spine

Dr. Ben Humpherys and Dr. Michael Derr are specialists in physical medicine with practices at Tanner Clinic Layton.

Dr. Humpherys’ practice concentrates on spine and back pain, while next-door colleague Dr. Michael Derr works with patients seeking to relieve pain in the spine and peripheral joints like arms, legs, fingers, wrists, knees and shoulders.

Because Dr. Humpherys’ injections must be precisely targeted to the epidural space surrounding the bony structures of the spine, he uses fluoroscopy, a kind of live x-ray that shows bone structures.

Dr. Derr uses ultrasound, which reveals blood veins, tendons and tissue. Using ultrasound-guided injections, he can avoid veins and other tissue as he precisely targets his injections into muscle and joints. He also uses fluoroscopy.
