Sacral metastases represent the lowest percentage of invasion to the spine, however, as chemotherapy treatments progress, the cancer survival rate has become higher, and the percentage of sacral metastases has increased. Treatment options for sacrum metastases are surgery, radiotherapy, and minimally invasive techniques such as sacroplasty and radiofrequency ablation. Knowing the repercussions that advancing the needle anteriorly (viscera) or medially (sacral roots) can have during the sacroplasty we are describing a technique to perform c-arm sacroplasty in coaxial vision, to identify the anterior sacral cortical bone that is in the limits of the pelvic viscera as well as the sacral foraminal line. ⋯ It is important to offer an adequate quality of life to patients with sacral fractures, whether associated with cancer or sacral insufficiency fractures (SIF). Sacroplasty, being a recently described technique, can be a very viable option for these patients, that's why it is important to have safe and reliable techniques to complement the approach of this minimally invasive technique.The coaxial access may be a safe and practical way to perform sacroplasty in these patients.

Osteoarthritis (OA) is a chronic painful condition that often affects large joints such as the knee. Treatment guidelines recommend paracetamol, nonsteroidal anti-inflammatory drugs (NSAIDs), and opioids. Antidepressants and anti-epileptic drugs (AEDs) are commonly prescribed for chronic noncancer pain conditions including OA, as an off-label use. This study describes analgesic utilization in patients with knee OA at population level using standard pharmaco-epidemiological methods. ⋯ There was an overall increase in the prescribing of analgesics apart from NSAIDs. Opioids were the most frequently prescribed class; however, the greatest increase in prescribing between 2000 and 2014 was observed in AEDs.

Identifying EEG brain markers might yield better mechanistic insights into how chronic pain develops and could be treated. An existing longitudinal EEG study gave us the opportunity to determine whether the development of pain is accompanied by less alpha power-ie, a "relaxed" brain state-and vice versa. ⋯ Transitions in pain states are linked to a change in baseline EEG activity. Future research is needed to replicate these results in a larger study sample and in targeted clinical populations. Furthermore, these results might be beneficial in optimizing neurofeedback algorithms for the treatment of chronic pain.

This study was performed to compare the perfusion index (PI) between affected and unaffected limbs in patients with complex regional pain syndrome (CRPS); it also evaluated the usefulness of the PI for monitoring the response to intravenous ketamine infusion therapy in such patients. ⋯ The PI significantly differed between affected and unaffected limbs in patients with CRPS. The PI may be useful for monitoring the response to intravenous ketamine therapy in patients with CRPS.

Chronic pain has a substantial negative impact on work-related outcomes, which underlines the importance of interventions to reduce the burden. Spinal cord stimulation (SCS) efficiently relieves pain in specific chronic pain syndromes and is recommended for treating failed back surgery syndrome (FBSS) or post-surgical chronic back pain that is refractory to other treatments. To examine the impact of SCS in patients with FBSS on the return to work (RTW), we determined the RTW rate and the factors positively associated with the RTW. ⋯ Our protocol for SCS for patients with FBSS, including a strict selection of patients and a multidisciplinary approach, led to good results, especially for the RTW. RTW should be a therapeutic goal, directly affecting indirect costs related to FBSS.
