Background: Recent studies have unveiled the intricate and distinctive nature of fascia, no longer regarding it solely as a muscle container. Recent research highlights its complex innervation and structure, signifying its significance in chronic pain pathways. Methods: We conducted a systematic literature search (updated on February 2024) to evaluate the role of fascial plane blocks in chronic pain treatment. All article types (randomized clinical trials, prospective and retrospective observational studies along with case reports and case series) were deemed eligible for inclusion if they referenced “fascial plane blocks” for the control of chronic pain conditions (persistent post-surgical, neuropathic, musculoskeletal-myofascial and cancer-related) and were published between 2010 and February 2024. Results: The search revealed an increasing evidence in the literature for the implementation of fascial blocks in chronic pain management, although still heavily limited to case reports or series. Conclusion: With the integration of ultrasound technology and a deeper understanding of their mechanisms of action, the fascial plane blocks continue to broaden their application also in chronic pain management, as a part of a multimodal strategy or as an alternative to conventional drugs or opioids.

A hip fracture is a serious injury with life-threatening complications, and its risk rises with increasing age. A hip fracture can be a very painful condition, and prompt surgical treatment is recommended to reduce pain and complications. Pain management is considered integral to the management of a broken hip. The choice between general and regional anesthesia in hip fracture surgery continues to be a topic of debate because risks are potentially associated with both approaches. Nerve blockades have proven to be effective in reducing acute pain after a hip fracture and in the perioperative period. For this reason, many regional techniques have been introduced, such as the lumbar plexus block, fascia iliac block, femoral nerve block, and recently, the pericapsular nerve group (PENG) block. Hip joint innervation is complex, not limited to the lumbar plexus but also depending on the sciatic nerve and branches of the sacral plexus (superior and inferior gluteal nerves and an articular branch from the quadratus femoris nerve). We hypothesized that a combination of two emerging regional anesthesia techniques, such as the PENG block and sacral erector spinae plane (S-ESP) block, could represent a good option to obtain pain control of the whole hip joint without opioid administration intraoperatively and postoperatively. Here, we report the cases of three frail patients with significant comorbidities who underwent hip fracture surgery (two cases of intramedullary nailing and one hemiarthroplasty), in which we preoperatively performed PENG and S-ESP blocks. We registered optimal intraoperative and postoperative pain control up to 48 hours after surgery without complications and without opioid administration, allowing the surgery to be performed with intravenous sedation or laryngeal mask general anesthesia. The surgeries were uneventful, and no complications were reported. This approach warrants further investigation in hip fracture surgery.

Introduction The sacral erector spinae plane (S-ESP) block is a recently described regional anesthesia technique that targets sacral dermatomes. First reported in 2019, it has been increasingly explored as a potential option for perioperative analgesia in surgeries involving the sacral, perineal, and pelvic regions. This review aims to summarize and critically appraise the current anatomical, technical, and clinical evidence on the S-ESP block, outlining its mechanisms of action, approaches, efficacy, and safety while identifying research gaps and future directions. Methods We performed a narrative review integrating anatomical descriptions, sonographic techniques, and available randomized controlled trials (RCTs) evaluating the clinical efficacy of the S-ESP block. A comprehensive literature search was conducted in PubMed, Embase, Scopus, Web of Science, and Ovid (Medline) from inception to July 21, 2025, without language or date restrictions. Full-text RCTs investigating ultrasound-guided S-ESP blocks for perioperative analgesia were reviewed and summarized. Results Fourteen RCTs (published 2023–2025) were included, conducted predominantly in Turkey, India, and Egypt, spanning pediatric (6 months to 12 years) and adult populations undergoing circumcision, hypospadias repair, hemorrhoidectomy, pilonidal sinus surgery, transurethral resection of prostate, lumbar discectomy, and total hip arthroplasty. Most pediatric trials compared midline S-ESP with caudal or penile blocks, generally demonstrating a longer time to first rescue analgesia and reduced postoperative analgesic consumption, although one study reported a superior duration with caudal block. In adults, the S-ESP block consistently reduced pain scores and opioid requirements. Conclusions Current evidence suggests that both midline and paramedian S-ESP techniques are technically feasible, appear safe in the short term, and provide clinically relevant postoperative analgesia in selected pediatric urogenital, adult anorectal, and orthopedic surgeries. However, heterogeneity in techniques, small single-center samples, and a narrow range of indications limit its generalizability. Large, multicenter RCTs with standardized protocols are needed to clarify the optimal approaches, dosing strategies, and comparative role of S-ESP block versus established neuraxial and peripheral techniques.
