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.

Vertebroplasty (VP) and kyphoplasty (KP) are emerging procedures for almost immediate pain relief when treating osteoporotic or osteolytic fractures. The main reported complication is polymethylmethacrylate (PMMA) leakage, which may lead to compression of neural structures or embolism. Different authors have proposed that intravertebral pressure (IP) is an important factor determining the risk for leakage, although so far only limited information has been gathered from clinical and experimental studies. There is also a lack of understanding of the IP during conventional interventions in VP and KP in the clinic. ⋯ This study showed that the IP of compressed vertebrae was significantly higher than that of adjacent normal vertebrae. There was a significant increase in IP during the PMMA filling in VP and KP; the IP of compressed vertebrae was not significantly reduced by the balloon inflation in KP, and no statistically significant differences in IP were found during all common stages of PMMA filling in VP and KP.

The clinical management of osteolytic metastases involving C2 is unique, because it is challenging to approach these lesions. Symptoms may vary from local pain to progressive neurological deficit. Surgery or radiotherapy have been the treatments of choice for several years; however, surgery may not bean option for patients with multiple metastases and poor general medical status, and radiotherapy carries the risk of vertebral collapse and consequent neural compression due to delayed bone reconstruction. Through different approaches, vertebroplasty has been introduced into clinical practice as an alternative to traditional surgical and radiotherapy treatments of osteolytic metastases at C2. ⋯ Vertebroplasty via an anterolateral approach is an effective technique to treat osteolytic metastases involving C2. It is a valuable, minimally invasive, and efficient method that allows quick and lasting resolution of painful symptoms.
