The epidural lysis of adhesions (ELOA) procedure supposedly has a biomechanical component in addition to the targeted injection of medications into the epidural space. It is assumed that the catheters used for the ELOA procedure can release epidural scars and adhesions. ⋯ According to our findings and arguments, the ELOA procedure is predominantly a method for the highly targeted application of epidural medications and possibly also has a lavage effect. A mechanical lysis of scars or adhesions appears unlikely.

Degenerative spondylolisthesis is one of the major causes for low back pain. Morphological abnormalities of the zygapophysial joints are a predisposing factor in the development of degenerative spondylolisthesis. Therefore, radiofrequency neurotomy seems to be a rational therapy. ⋯ Zygapophysial joints are a possible source of pain in patients with spondylolisthesis. Radiofrequency neurotomy is a rational, specific nonoperative therapy in addition to other nonoperative therapy methods with a success rate of 65%. This is the first study to determine the effect of radiofrequency neurotomy in patients with minor degenerative spondylolisthesis.

Fluoroscopic cervical interlaminar epidural injections in managing chronic pain of cervical postsurgery syndrome: preliminary results of a randomized, double-blind, active control trial.
Cervical postsurgery syndrome is common with increasing cervical surgical interventions. Cervical spine surgery may fail in a certain proportion of patients with continued pain secondary to pseudoarthrosis, adjacent segment degeneration, inadequate decompression, iatrogenic instability, facet joint arthritis, deformity, and spinal stenosis. Among the various treatments available for managing cervical postsurgery syndrome, epidural steroid injections are one of the most common nonsurgical interventions. However there have not been any systematic evaluations regarding the effectiveness of cervical epidural injections in cervical postsurgery syndrome. ⋯ NCT01071369.

Effective early antiviral treatments reduce both acute zoster pain and the risk of postherpetic neuralgia. The authors hypothesized that the direct neuraxial administration of acyclovir could provide superior drug application to the spinal neural structures with a higher viral burden and have various advantages over the other routes of drug administration in terms of required doses, side effects, and efficacy. ⋯ There was no evidence of neurological and histopathological abnormalities following intrathecal acyclovir injection.
