Chronic pain is a debilitating, multifactorial condition. The purpose of this study was to examine patient characteristics of those who did not show up for their scheduled first pain medicine appointment in order to identify factors that may improve access to care. ⋯ High no-show rates were present particularly among younger patients. Having a referral from another specialty was an independent predictor of lower no-show rates.

Radiofrequency ablation (RFA) is an interventional procedure that has been used to treat chronic back pain for over 50 years; this unique case report demonstrates the effectiveness of pulsed radiofrequency ablation (PRFA) on the dorsal root ganglion (DRG) in the treatment of chronic radicular pain (Russo et al., 2021, J Pain Res, 14, 3897). The RFA provides pain relief by using thermal energy to disrupt peripheral nerves carrying nociceptive signals back to the central nervous system (Abd-Elsayed et al. 2020, Pain Ther, 9, 709). However, there is a lack of literature about the safety and efficacy of PRFA of the DRG.

Comparative Study
A comparison of MRI and intraoperative measurements to determine interspinous spacer device size.
To determine whether preoperative magnetic resonance imaging (MRI) can reliably determine intraoperative measurements in the Vertiflex Interspinous Spacer (ISS) procedure. ⋯ Measuring interspinous space on MRI yielded, on average, a value smaller than the intraoperative measurement in Vertiflex ISS procedures, but the mean differences were not significant. Good agreement and moderate reliability were found between observer MRI and surgeon intraoperative measurements, suggesting MRI can evaluate the intraoperative space for the Vertiflex ISS procedure. Preoperative MRI measurement may help decrease complications by aiding in surgical decision-making through providing a reference for intraoperative measurements. Further prospective study is necessary to determine if preoperative MRI measurement can predict and potentially replace the need for intraoperative measurement.

In the last 20 years, we have seen the flourishing of multiple treatments targeting the dorsal root ganglion (DRG) for pain. However, there is concern regarding the variation in the location of the DRG, which could influence the long-term clinical outcomes. The aim of this work was to determine the exact position of the DRG in the spine and propose a pre-surgical planning. ⋯ Percutaneous treatments for chronic pain directed at the DRG are effective. Clinical outcomes depend of good preoperative planning that allows for optimizing its effects. We propose a DRG morphology evaluation scale useful for the planning process prior to any treatment directed at the ganglion.
