Randomized Controlled Trial
Preliminary results of a randomized, equivalence trial of fluoroscopic caudal epidural injections in managing chronic low back pain: Part 3--Post surgery syndrome.
Post surgery syndrome resulting in persistent pain following lumbar spine surgery is common. Speculated causes of post lumbar surgery syndrome include stenosis, degeneration of adjacent segments, internal disc disruption, recurrent disc herniation, retained disc fragment, epidural or intraneural fibrosis, radiculopathy, and various other causes. Epidural injections are most commonly used in post surgery syndrome. There is lack of evidence for the effectiveness of epidural injections in managing chronic low back pain with or without lower extremity pain secondary to post surgery syndrome. ⋯ Caudal epidural injections in chronic function-limiting low back pain in post surgery syndrome without facet joint pain demonstrated effectiveness with over 55% of the patients showing improvement in functional status with significant pain relief in 60% to 70%.

Randomized Controlled Trial
Preliminary results of a randomized, equivalence trial of fluoroscopic caudal epidural injections in managing chronic low back pain: Part 2--Disc herniation and radiculitis.
The pathophysiology of lumbar radicular pain is a subject of ongoing research. The prevalence of sciatica or radiculitis ranges from 1.2% to 43%. Epidural injections are one of the most commonly performed interventions in the United States in managing chronic low back and lower extremity pain secondary to disc herniation and radiculitis. There is a paucity of evidence with contemporary methodology used in performing epidural injections under fluoroscopy and based on pain relief and functional status improvement. ⋯ Caudal epidural injections with or without steroids may be effective in patients with disc herniation or radiculitis with between 79% to 91% of patients showing significant pain relief and improvement in functional status.

Randomized Controlled Trial
Preliminary results of a randomized, equivalence trial of fluoroscopic caudal epidural injections in managing chronic low back pain: Part 1--Discogenic pain without disc herniation or radiculitis.
Intervertebral discs, facet joints, ligaments, fascia, muscles, and nerve root dura have been described as tissues capable of transmitting pain in the low back. The pathophysiology of spinal radicular pain is the subject of ongoing research and controversy with discogenic pain assuming a major role as a cause of non-specific low back pain. Even though epidural injections are frequently administered in managing axial low back pain, the evidence is lacking. ⋯ Caudal epidural injections with or without steroids may be effective in patients with chronic function-limiting low back pain without facet joint pain, disc herniation, and/or radiculitis in over 70% of the patients.

Randomized Controlled Trial
Preliminary results of a randomized, equivalence trial of fluoroscopic caudal epidural injections in managing chronic low back pain: Part 4--Spinal stenosis.
Spinal stenosis is one of the 3 most common diagnoses of low back and leg symptoms which also include disc herniation and degenerative spondylolisthesis. Spinal stenosis is a narrowing of the spinal canal with encroachment on the neural structures by surrounding the bone and soft tissue. In the United States, one of the most commonly performed interventions for managing chronic low back pain are epidural injections, including their use for spinal stenosis. However, there have not been any randomized trials and evidence is limited with regards to the effectiveness of epidural injections in managing chronic function-limiting low back and lower extremity pain secondary to lumbar spinal stenosis. ⋯ Caudal epidural injections with or without steroids may be effective in patients with chronic function-limiting low back and lower extremity pain with spinal stenosis in approximately 60% of the patients.

Randomized Controlled Trial Clinical Trial
Effectiveness of thoracic medial branch blocks in managing chronic pain: a preliminary report of a randomized, double-blind controlled trial.
Thoracic facet joints have been implicated as the source of chronic pain in the mid back or upper back in 34% to 48% of the patients. Various therapeutic techniques utilized in managing chronic thoracic pain of facet joint origin include intraarticular injections, medial branch blocks, and radiofrequency neurotomy of thoracic facet joint nerves. ⋯ The majority of the patients in both groups experienced significant pain relief and improvement in functional status. Therapeutic thoracic medial branch blocks, with or without steroid, may provide a management option for chronic function-limiting mid back or upper back pain of facet joint origin.
