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.

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.

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.

Guideline development seems to have lost some of its grounding as a medical science. At their best, guidelines should be a constructive response to assist practicing physicians in applying the exponentially expanding body of medical knowledge. In fact, guideline development seems to be evolving into a cottage industry with multiple, frequently discordant guidance on the same subject. ⋯ A recent manuscript published by Chou et al, in addition to previous publications, appears to have limited clinician involvement in the development of APS guidelines, and demonstrates some of these challenges clearly. This manuscript illustrates the deficiencies of Chou et al's criticisms, and demonstrates their significant conflicts of interest, and use a lack of appropriate evaluations in interventional pain management as a straw man to support their argument. Further, this review will attempt to demonstrate that excessive focus on this straw man has inhibited critique of what we believe to be flaws in the approach.

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.
