Objective Ultrasound-guided tibial nerve pulsed radiofrequency (US-guided TN PRF) and fluoroscopy-guided intralesional radiofrequency thermocoagulation (FL-guided intralesional RFT) adjacent to the painful calcaneal spur are two interventions for pain management in painful calcaneal spur and plantar fasciitis. This study aimed to compare the effectiveness of the two procedures. Design A prospective, randomized, single-blind study. Setting Single-center pain clinic. Subjects Forty-nine patients who met the inclusion criteria were randomized into two groups. Methods Group U (25 patients) received US-guided TN PRF at 42°C for 240 s, whereas Group F (24 patients) received FL-guided intralesional RFT at 80°C for 90 s. The most severe numeric rating scale (NRS) score during the first morning steps and the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores were used to evaluate the effectiveness of the procedures. The study's primary outcome assessed treatment effectiveness via the NRS, whereas the secondary outcomes included changes in the AOFAS score and the incidence of procedure-related mild adverse events. Results NRS and AOFAS scores significantly improved in Groups U and F at 1 and 3 months compared with baseline (P  < .05), and there was no significant difference between the groups. At month 1, 50% or greater pain relief was achieved in 72% of patients in Group U and 75% of patients in Group F. No significant difference was observed in the incidence of mild adverse events between the groups. Conclusions US-guided TN PRF and FL-guided intralesional RFT have shown significant effectiveness in the treatment of painful calcaneal spur and plantar fasciitis. Larger randomized controlled trials are needed. Clinical Trial Number NCT06240507. [ABSTRACT FROM AUTHOR]

Ultrasound (US)-guided cervical selective nerve root block (CSNRB) procedures are increasingly being performed as an alternative to conventional fluoroscopy (FL)-guided epidural injections for the treatment of cervical radicular pain. The aim of this study was to compare the effectiveness of US-guided CSNRB versus FL-guided interlaminar cervical epidural steroid injection (IL-CESI) for cervical radicular pain. A total of 60 patients with cervical radicular pain due to a single-level disc herniation were randomized into either the FL or US group. The numeric rating scale, Short Form-36, and neck disability index were evaluated before treatment at months 1, 3, and 6 after treatment. Procedure time, complications, pain medication consumption, and patient satisfaction were also recorded. Patients experienced significant improvement in pain, disability, and quality of life scores up to 6 months after the procedure (p < 0.001). Treatment success rate was achieved in 56.6% of the IL-CESI group and 50% of the CSNRB group without any significant difference between the study arms (p = 0.617). US-guided CSNRB was shown to be as effective as the FL-guided IL-CESI in the treatment of cervical radicular pain, in addition to the absence of radiation exposure and requiring less procedure time.

Objectives Genicular nerve radiofrequency procedures increasingly are being performed to treat chronic pain due to knee osteoarthritis. Targeting additional sensory nerves and improving target identification by using ultrasound guidance could improve treatment success. The aim of this study was to compare the effectiveness of targeting only the traditional genicular nerves versus targeting the traditional genicular nerves plus 2 additional sensory nerves in ultrasound-guided genicular nerve radiofrequency procedures in patients with chronic knee osteoarthritis. Methods A total of 80 patients were randomized into 2 groups. Patients in the 3-nerve-targeted group received a genicular radiofrequency procedure in which the traditional genicular nerves were targeted: the superior lateral, superior medial, and inferior medial nerves. The 5-nerve-targeted group received a genicular radiofrequency procedure in which the recurrent fibular and infrapatellar branches of the saphenous nerve were targeted in addition to the traditional genicular nerves. The numeric rating scale, Short Form-36, Western Ontario and McMaster Universities Arthritis Index, Quantitative Analgesic Questionnaire, and patient satisfaction were evaluated before treatment, at week 1 after treatment, and at months 1, 3, and 6 after treatment. Results Both techniques provided significant pain reduction and functional improvement up to 6 months after the procedure (P  < .05). The 5-nerve-targeted group showed significant improvement with regard to the numeric rating scale, Western Ontario and McMaster Universities Arthritis Index total, and Short Form-36 score compared with the 3-nerve-targeted group at each follow-up point. No differences in the Quantitative Analgesic Questionnaire or patient satisfaction scores were observed between the groups. Conclusions The ultrasound-guided 5-nerve-targeted technique is a safe method and a more effective therapeutic procedure than the traditional 3-nerve-targeted technique for chronic knee osteoarthritis.

Chronic pain affects a significant amount of the population and represents a heavy personal and socioeconomic burden. Chronic pain mechanisms can be categorized as nociceptive, neuropathic, or nociplastic. Although mechanism-based pain treatment is optimal, different types of pain mechanisms may overlap in patients. Recently, the biopsychosocial model with the multidisciplinary pain management program is widely accepted as one of the most effective methods to assess and manage chronic pain. The treatment of chronic pain consists of a personalized, stepwise, and multimodal approach that includes pharmacotherapy, psychotherapy, integrative treatments, and interventional procedures. Somatic and peripheral nerve blocks for the treatment of chronic pain are often deferred. With the increasing use of ultrasound in pain medicine, newly defined interfascial plane blocks, which may be performed alone or as an adjuvant to multimodal management, have gained popularity. Adequate pain management can improve physical functioning, mental health and quality of life indicators, and reduce pain chronification. The aim of this current article is to perform a comprehensive and updated review of existing treatment options, particularly interfascial plane blocks in chronic pain syndromes.

Background and objective Trigeminal neuralgia (TN) is a debilitating disorder characterized by acute episodic attacks of pain that significantly impair patients' quality of life and overall functioning. Initial therapeutic strategies to treat this condition include pharmacological options, particularly carbamazepine. In cases with resistance to dose escalation and polypharmacy, interventional procedures may be warranted. The primary aim of this study was to compare the efficacy of trigeminal ganglion (TG) radiofrequency thermocoagulation (RFT) and ultrasound (US)-guided maxillary/mandibular (max/mand) nerve pulsed radiofrequency (PRF) for treating TN, based on the findings at six months post-treatment. The secondary aims were to assess the impact of these interventions on drug consumption and interventional safety based on adverse events. Methods This prospective, randomized, single-blind study was conducted at a single pain clinic. Forty-four patients were randomized into two groups. Group RFT received TG RFT at 60 °C, 65 °C, and 70 °C for 60 seconds each, whereas Group PRF received max/mand PRF for 240 seconds. Pain relief was assessed by using the numeric rating scale (NRS) and intervention effectiveness on medication consumption was evaluated by using the Medication Quantification Scale III (MQS III). The rates of intervention-related adverse events were also compared. Results Both RFT and PRF significantly alleviated pain at one and six months post-treatment compared to baseline (p<0.05). No statistical differences were found in the NRS and MQS III scores between the groups. At six months, 77.3% of RFT patients and 63.9% of PRF patients experienced at least 50% pain relief, with no statistically significant difference. Hypoesthesia occurred in two RFT patients, and masseter weakness was observed in one patient, while no adverse events were reported in the PRF group. Conclusions TG RFT and max/mand PRF are effective treatments for TN. US-guided max/mand PRF, which avoids RFT-associated complications and radiation exposure, may be the superior and preferable option. In this study, the potential space between the coronoid process and maxilla was used to access the maxillary nerve during the maxillary block and PRF procedures, in contrast to the classical approach through the mandibular notch.
