Vertebral augmentation: update on safety, efficacy, cost effectiveness and increased survival?
Although over 300 articles have been published annually on vertebral augmentation in the last 5 years, there remains much debate about a fundamental question - is vertebral augmentation a safe and effective treatment to achieve analgesia, reduce disability, and improve quality of life in patients with a vertebral fracture? In this modern era of evidence-based clinical practice and public health care policy and funding, an evidentiary basis is needed to continue to perform vertebral augmentation. The aim of this narrative review is to summarize the latest and highest quality evidence for efficacy, safety, cost effectiveness, and potential survival benefit after vertebroplasty and kyphoplasty. The design, major inclusion criteria, primary outcome measures, relevant primary baseline characteristics, primary outcomes, relevant secondary outcomes, and limitations of prospective multicenter randomized sham-controlled and conservative management-controlled trials are summarized. ⋯ Finally, emerging literature assessing the potential cost-effectiveness of vertebral augmentation is considered. This narrative review will provide interventional pain physicians a summary of the latest and highest quality data published on vertebral augmentation. This will allow integration of the best available evidence with clinical expertise and patient wishes to make the most appropriate evidence-based clinical decisions for patients with symptomatic vertebral fracture.

Discogenic pain is an important cause of low back pain (LBP). We have developed a pulsed radiofrequency (PRF) technique, using Diskit II needles (NeuroTherm, Middleton, MA, USA) placed centrally in the disk, for applying radiofrequency current in the disc (Intradiscal PRF method). ⋯ This intradiscal PRF method with consecutive PRF 5/5/60V, 15 min (with Diskit needle) appears to be a safe, minimally invasive treatment option for patients with chronic discogenic LBP.

Pain prevalence at various stages of cancer ranges from 27% to 60% for outpatients. Yet, how pain is managed in this patient group is poorly understood. ⋯ Pain remains a significant problem in medical oncology outpatients, and often pain is insufficiently managed. Patients with a high pain intensity were more at risk to experience pain related interference with daily activities, but even some patients suffering mild pain experienced this. As adequate pain relief for up to 86% of the patients with cancer should be feasible, pain in medical oncology outpatients is still undertreated. Taking into account the interference of pain with daily activities and predictors of pain will facilitate cancer pain management. The study has been approved by the Medical Ethics Committee (CMO) in all 7 hospitals (METC protocol number 2011/020) and has been registered by the Dutch Trial register (NTR): NTR2739.

The high prevalence of persistent low back pain and growing number of diagnostic and therapeutic modalities employed to manage chronic low back pain and the subsequent impact on society and the economy continue to hold sway over health care policy. Among the multiple causes responsible for chronic low back pain, the contributions of the sacroiliac joint have been a subject of debate albeit a paucity of research. At present, there are no definitive conservative, interventional or surgical management options for managing sacroiliac joint pain. It has been shown that the increases were highest for facet joint interventions and sacroiliac joint blocks with an increase of 310% per 100,000 Medicare beneficiaries from 2000 to 2011. There has not been a systematic assessment of the utilization and growth patterns of sacroiliac joint injections. ⋯ This study illustrates the explosive growth of sacroiliac joint injections even more than facet joint interventions. Furthermore, certain groups of providers showed substantial increases. Overall, increases from 2008 to 2010 were nominal with 1%, but some states showed over 20% increases whereas some others showed over 20% decreases.

Case Reports
Vertebroplasty for the compression of the dorsal root ganglion due to spinal metastasis.
Radicular pain has been considered to be a relative contraindication to vertebroplasty. It was reported by some authors in the literature that percutaneous vertebroplasty (PV) in these conditions were performed without complications. ⋯ We suggest that carefully performed PV is an option for terminally ill patients with epidural and dorsal root ganglion involvement who do not respond to conservative treatment or cannot undergo radiation therapy and surgery. PV is minimally invasive compared to open surgery and may merit serious consideration in patients with limited physiologic reserves.
