Piriformis syndrome (PS) is a painful condition caused by entrapment of the sciatic nerve within the piriformis muscle. PS is typically unilateral and mainly occurs related to entrapment of the sciatic nerve. Treatments include physiotherapy, analgesics, anti-inflammatory drugs, behavioral modifications, injection therapy with local anesthetics (LAs) and steroids, epidural injection, botulinum toxin (BT) injection, and surgery. ⋯ In patients with PS, satisfactory pain improvement can be obtained by BT, LA plus CS, LA, or CS injection therapy. Injection of LA plus CS showed the best efficacy.

Randomized Controlled Trial
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.

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.

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.

The COVID-19 pandemic resulted in a novel challenge for healthcare delivery and implementation in the United States (US) in 2020 and beyond. Telemedicine arose as a significant and effective medium for safe and efficacious physician-patient interactions. Prior to the COVID-19 pandemic, telemedicine while available, had infrequently been utilized in pain medicine practices due to difficulties with reimbursement, the learning curve associated with new technology usage, and the need for new logistical systems in place to implement telemedicine effectively. Given the unique constraints on the healthcare system during the COVID-19 pandemic, the ubiquitous utilization of telemedicine among pain medicine physicians increased, giving insight into potential future roles for the technology beyond the pandemic. ⋯ Telemedicine as an emerging technology for efficient communication played a key role in mitigating the adverse effects of the COVID -19 pandemic on chronic pain patients. The utilization of telemedicine remarkably increased after the start of the pandemic within 1 to 2 weeks. Overall, private hospital-based centers were significantly less likely to implement telemedicine than academic centers, possibly due to limited access to secure telemedicine platforms and high start-up costs. Telemedicine was used more frequently for follow-up visits than initial visit encounters at most centers. In spite of the unforeseen consequences to the healthcare system and chronic pain practices in the US from COVID-19, telehealth has emerged as a unique model of care for patients with chronic pain. Although it has flaws, telehealth has the ability to increase access to care beyond the end of the pandemic. Further identification of barriers to the use of telemedicine platforms in private practices should be addressed from a policy perspective to facilitate increased care access.
