The most common presentation of cluneal neuropathy is ipsilateral low back and gluteal pain. Cluneal neuralgia has been described historically in surgical contexts, with much of the description and treatment related to entrapment and decompression, respectively. Treatment options for addressing axial low back pain have evolved with advancements in the field of interventional pain medicine, though clinical results remain inconsistent. Recent attention has turned toward peripheral nerve stimulation. Nonsurgical interventions targeting the superior and medial cluneal nerve branches have been performed in cases of low back and buttock pain, but there is no known review of the resulting evidence to support these practices. ⋯ Limited studies promote beneficial effects from interventions intended to target cluneal neuropathy. Despite increased emphasis and treatment options for this condition, there is little consensus on the diagnostic criteria, endpoints, and measures of therapeutics, or procedural techniques for blocks, radiofrequency, and neuromodulation. It is imperative to delineate pathology associated with the cluneal nerves and perform rigorous analysis of associated treatment options.

Analysis of Somatosensory Profiles Using Quantitative Sensory Testing During Tonic and BurstDR Stimulation for the Treatment of Chronic Pain.
In the presence of neuropathic pain, other sensory qualities, such as touch or pressure, which are a sign of nerve damage, are almost always affected. However, it is unclear to which extent spinal cord stimulation (SCS) influences these simultaneously damaged sensory pathways or possibly contributes to their regeneration. ⋯ In this study, it could be shown that, in some QST parameters and tested fiber functions, normalization tendencies were recognizable by using BurstDR or tonic SCS. However, BurstDR SCS seemed to be superior to tonic stimulation in this regard.

Radiofrequency ablation (RFA) for the lumbar facet joints has demonstrated efficacy in the management of chronic low back pain. The traditional technique uses a conventional monopolar (CM) cannula placed parallel to the putative nerve to produce a thermal lesion resulting in pain relief of the facet joints. A new multi-tined (MT) cannula has come onto the market that allows targeting the putative nerve using a perpendicular to the nerve approach. ⋯ This study demonstrated that the outcomes in terms of pain, disability, quality of life, adverse events, and fluoroscopy exposure time were equivalent between the 2 cannulae. However, RFA using the MT cannula was faster to perform and involved less local anesthetic and radiation.

Adjacent vertebral fracture (AVF) seemed to be a frequent and severe complication in osteoporotic vertebral compression fracture (OVCF) patients receiving percutaneous vertebroplasty or percutaneous kyphoplasty (PKP), resulting in poor long-term outcome and recurrence of pain-related symptoms. Nonetheless, its mechanism remains unclear. ⋯ The risk of AVF should be focused, especially when OVCF patients with the following predictors: (1) BMD < -3.45; (2) kyphosis angle at last follow-up > 15.5°; (3) I or II cement distribution; and (4) IV or V disc degeneration. More prophylactic treatment should be prescribed for these patients to avoid the occurrence of AVF.

Preoperative exposure to opioids has recently shown to be associated with poor outcomes after elective major surgery, but little is known as to how pretreatment opioid use affects results of interventional back pain management. ⋯ Pretreatment opioid use is associated with greater pain discomfort, impairment, and reduced functional ability, as well as poorer long-term effect of interventional back pain treatment at one-month follow-up. In our study, opioid users reported the same positive effects of facet joint nerve blocks immediately after the treatment and 2 hours after the treatment, but a significantly smaller effect at one-month follow-up. This could indicate that opioid use may diminish the effects of pain treatments by affecting relearning, behavioral changes, and central pain modulation. These findings may help providers understand the effect of pretreatment opioid use on patient care, and its implications on hospital and societal costs.
