Pain Management Procedure examples:

Epidural Steroid Injection

The Epidural Steroid Injection is a procedure where a numbing medicine (anesthetic) and an anti- inflammatory medicine (steroid) is injected into the epidural space to treat pain caused by irritation of the spinal nerves. A protective covering called the dural sac surrounds the spinal cord. This sac contains spinal fluid that bathes and nourishes the spinal cord. The space between the outer surface of the dural sac and the bones of the spinal column is the epidural space. Nerves that go from the spinal cord, through the spinal column and to the body pass through the epidural space. Depending on the location of your pain, the epidural steroid injection can be given in the neck (cervical), middle back (thoracic) or lower back (lumbar).

Sacroiliac Joint Injection

A Sacroiliac Joint Block is an injection procedure used to diagnose and treat lower back pain associated with injury or disease to the sacroiliac joint. The sacroiliac joints are located in the area of the lower back and buttocks where the pelvis joins with the spine. Injury and disease to these joints will cause pain in the lower back, buttocks, abdomen, groin, and legs. The medicine injected reduces inflammation and swelling inside the joint space, which may in turn reduce the pain.

Lumbar Facet Injection

The Lumbar Facet Joint Injection is a procedure used to block or decrease pain caused by problems in the lumbar (lower back) spine. Lumbar facet joints, which are not much larger than your thumbnail, are located on either side of each vertebrae. They provide stability and guide motion in the low back. If the joints become inflamed, you may experience not only lower back pain, but also pain in the abdomen, buttocks, groin and legs.

Radio-Frequency Ablation or Rhizotomy

Radio-frequency Ablation, or Rhizotomy, is a procedure used to selectively disconnect problematic nerves surrounding the facet joints. The nerves to be ablated are identified by performing diagnostic facet joint injections with local anesthetic (sometimes combined with steroid for additional therapeutic effect). If diagnostic blocks provide even short-lasting pain relief, there is an indication for RF Ablation. The relief achieved by Rhizotomy may last for up to 6 – 24 months. Because nerves regenerate over time, the procedure may be repeated when the pain returns.

Joint Injection

Joint injections of the extremities, such as in the knees, shoulders, hips, etc., are used to treat the pain most commonly caused by arthritis. The joints of the extremities can undergo degeneration from constant wear-and-tear (osteoarthritis), as well as from injury (chronic sprains) or from disease (rheumatoid arthritis), thus leading to chronic inflammation and pain. If the inflammation is severe and left untreated, the joint can become permanently damaged from erosion and destruction of the cartilage lining that lubricates the moving parts of the joint.
The biggest joints of the extremities (such as the shoulders, hips and knees) are the ones most commonly afflicted with arthritis. Arthritis can also involve the smaller joints, such as the ankles, wrist and finger joints. The medicine injected (corticosteroid) reduces the inflammation and swelling inside the joint space. This in turn treats pain in the long term.

Trigger Points Injections

Trigger point injections (TPI) are used to treat extremely painful areas of muscle. A normal muscle contracts and relaxes when it is active. A trigger point is a knot or tight, ropy band of muscle that forms when a muscle fails to relax. The knot can often be felt under the skin and may twitch involuntarily when touched (called a jump sign).
The trigger point can trap or irritate surrounding nerves and cause referred pain — pain felt in another part of the body. Scar tissue, loss of range of motion, and weakness may develop over time.
TPI is used to alleviate myofascial pain syndrome (chronic pain involving tissue that surrounds muscle) that does not respond to other treatment, although there is some debate over its effectiveness. Many muscle groups, especially those in the arms, legs, lower back, and neck, are treated by this method. TPI also can be used to treat Fibromyalgia and tension headaches.

Spinal Cord Stimulator

The Spinal Cord Stimulator is indicated in those patients who have failed all other conservative treatments. In case they cannot have more surgery, previous surgeries unsuccessful, develop tolerance too pain medications and all other attempts at pain treatment have failed.

Spinal Cord Stimulator usually helps with more localized pain patterns such as upper back pain radiating into arms or lower back pain radiating into legs.

With the stimulator the pain is substituted by a sensation that feels more like some kind of vibration or warm tingling. The stimulator sits in the epidural space and does not touch the spinal cord.

The stimulator can be easily removed at a later time, but it’s removal will result with the return of the pain.
