Randomized Controlled Trial
Fluoroscopic epidural injections in cervical spinal stenosis: preliminary results of a randomized, double-blind, active control trial.
Cervical spinal stenosis is a common disease that results in considerable morbidity and disability. There are multiple modalities of treatments, including surgical interventions and multiple interventional techniques including epidural injections. The literature on the effectiveness of cervical epidural steroids is sporadic. Emerging evidence for cervical interlaminar epidurals for various conditions in the cervical spine is positive; however, the effect of fluoroscopic epidural injections in cervical spinal stenosis has not been studied. ⋯ NCT01071369.

Vertebroplasty is a minimally invasive procedure demonstrated to be safe and effective in the treatment of painful osteoporotic and malignancy related fractures when performed in the thoracolumbar spine. Multiple randomized and nonrandomized reports have demonstrated its effectiveness. Conversely, transoral vertebroplasty (TOV) to treat the second cervical vertebra (C2) has been described in only a few case reports. ⋯ TOV is safe, effective, and long-lasting in the treatment of cervical pain resulting from malignant involvement of C2.

Intrathecal delivery of baclofen (ITB) is effective at controlling spasticity. However, it requires the placement of a catheter into the intrathecal space, and a pump with a reservoir for the medication. The process of placing the catheter and pump are prone to complications. ⋯ Complication rates after placement of intrathecal pump/catheters have increased in the pediatric population between 1997 and 2006 mainly due to an increase in mechanical complications.

In 2000 the intradiscal electrothermal therapy (IDET) procedure for the treatment of discogenic pain was introduced. The technique involves the positioning of an intradiscal catheter with a temperature-controlled thermal resistive heating coil at the inner posterior annulus. The therapeutic mechanism of IDET combines the thermo-coagulation of native nociceptors and in-grown nonmyelinated nerve fibers with collagen shrinkage, stabilizing annular fissures. Thermal nerve root injuries were described with IDET. The temperature in relation to the distance from the catheter tip was investigated. The intradiscal temperature distribution during treatment with IDET was also described. ⋯ This study shows that temperatures generated within the spinal canal during IDET do not appear to be high enough to cause nerve damage.

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.
