Cervical selective nerve root blocks (C-SNRBs) maintain utility for presurgical planning in patients with cervical radiculopathy. Traditional fluoroscopic or stationary computed tomography (CT)-guided methods have been associated with complications, including catastrophic neurologic insults, while ultrasound guidance has been investigated based on its theoretical advantages. Maximizing patient safety by obtaining superior anatomic and procedural details promotes the exploration for better alternative guidance. ⋯ We propose the PL-EF approach as the safest protocol for C-SNRBs. When compared with fluoroscopy or CT, CBCT/fluoroscopy is an advanced imaging system that provides superior anatomic neurovascular detail, while offering precise needle control, contrast media monitoring, and easy operation in an office setting. These advanced features support it as the ideal guidance method for maximizing both the safety and efficiency of the PL-EF C-SNRB approach. However, the claimed advantages cannot be concluded without increasing its accessibility to pain specialists and conducting a prospective study with a large sample size.

The situation generated in the health system by the COVID-19 pandemic has provoked a crisis involving the necessity to cancel non-urgent and oncologic activity in the operating room and in day-to-day practice. As the situation continues, the need to reinstate attention for patients with chronic pain grows. The restoration of this activity has to begin with on-site appointments and possible surgical procedures. On-site clinical activity has to guarantee the safety of patients and health workers. ⋯ We describe procedures to implement these recommendations for individual clinical situations, the therapeutic possibilities and safety guidelines for each center, and government recommendations during the COVID-19 pandemic.

Adhesive capsulitis and disorders of the intra-articular portion of the long head of the biceps brachii tendon are common causes of shoulder pain. Sonographic findings, coupled with clinical evaluation and medical history, are paramount for prompt diagnosis. Herewith, either to precisely confirm the pain generator(s) or to appropriately treat relevant cases, ultrasound-guided interventions are often required in daily clinical practice. Targeting the anatomical structures involved in the aforementioned pathological conditions, we briefly describe some technical tips and tricks as regards ultrasound-guided hydrodilatation of the shoulder capsule at the rotator interval.

Low-back pain (LBP) pathophysiological conditions include nociceptive back pain, somatic referred pain, radicular pain (RP), and radiculopathy. Differential diagnosis is challenging; guidance may come from patients' thorough clinical history and physical examination and, particularly for lumbar RP, from the evaluation of subjective responses of injured lumbar nerves to a strain applied at the buttock (buttock applied strain [BUAS] test). ⋯ Among patients with LBP, the BUAS test showed satisfactory sensitivity, specificity, prior probability, and inter-rater reliability; thus, it may be considered a useful adjunctive tool to diagnose RP in patients with LBP. For more generalized results, more research, in clinical settings other than pain clinics, is needed.

Multicenter Study Clinical Trial
10 kHz SCS for chronic postsurgical pain: Results from a 12-month prospective, multicenter study.
Chronic postsurgical pain (CPSP) can be caused by peripheral nerve injury (PNI) resulting from surgical procedures and has a significant neuropathic component. This prospective, single-arm study was conducted to document the effectiveness of 10-kHz spinal cord stimulation (10-kHz SCS) as a treatment for patients with CPSP. ⋯ 10-kHz SCS is effective and tolerated in patients with CPSP, and further study of its clinical application in this population is warranted.
