Randomized Controlled Trial
A randomized, double-blind controlled trial of lumbar interlaminar epidural injections in central spinal stenosis: 2-year follow-up.
While low back pain is the number one cause of disability in the United States, lumbar spinal stenosis along with intervertebral disc herniation and degenerative spondylolisthesis is one of the 3 most common diagnosis of low back and leg pain for which surgery is performed. Numerous modalities of treatments including drug therapy and complex surgical fusions have been recommended for treatment of central spinal stenosis. Epidural injections are one of the commonly performed nonsurgical interventions in managing central spinal stenosis; however, there has been paucity of literature in reference to efficacy of epidural injections in managing central spinal stenosis with lumbar interlaminar epidural injections. ⋯ NCT00681447.

Randomized Controlled Trial Comparative Study
Bilateral spinal decompression of lumbar central stenosis with the full-endoscopic interlaminar versus microsurgical laminotomy technique: a prospective, randomized, controlled study.
Extensive decompression with laminectomy, where appropriate, is often still described as the method of choice when operating on degenerative lumbar spinal stenosis. Nonetheless, tissue-sparing procedures are becoming more common. Endoscopic techniques have become the standard in many areas because of the surgical advantages they offer and the benefits for rehabilitation. One key issue when operating on the spine was the development of instruments to provide sufficient bone resection under continuous visual control. This was achieved by using endoscopes for operations carried out in cases of spinal canal stenosis. ⋯ The recorded results demonstrate that the full-endoscopic interlaminar bilateral decompression adopting a unilateral approach provides an adequate and safe supplement and alternative to the conventional microsurgical bilateral laminotomy technique when the indication criteria are fulfilled. At the same time, it offers the advantages of a minimally invasive intervention.
