Abstract

Purpose: Hip osteoarthritis is a common chronic condition primarily affecting the elderly, characterised by the presence of pain, joint stiffness, and restricted movement. Ultrasound-guided Pericapsular Nerve Group (PENG) block combined with viscosupplementation may offer symptomatic improvement in patients with hip osteoarthritis unable to undergo total hip arthroplasty. The aim of this study was to evaluate pain and function in patients with hip osteoarthritis following the administration PENG block combined with viscosupplementation.

Methods: A retrospective study of 17 consecutive patients (12 Female; 5 Male) with hip osteoarthritis who underwent ultrasound-guided PENG block combined with viscosupplementation were included in the study. The primary outcome was pain assessed using the Visual Analogue Scale (VAS), and function measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) before and 12 weeks after the procedure. The secondary outcome was complication rate.

Results: The mean and standard deviation age was 76.5 ± 8.3 years (range 63-93). There was a significant reduction in mean VAS of 3.6 points (p < 0.001) and a reduction in WOMAC score of 29.1 points (p < 0.001). The majority of participants reported being satisfied with the procedure (82.4%). The minor complication rate was 11.8% (ongoing pain requiring analgesia and transient hip flexor weakness). No major complications were observed during the follow-up period.

Conclusions: The ultrasound-guided PENG block combined with viscosupplementation demonstrated improvement in pain and function without major complications after 12 weeks of follow-up in patients with hip osteoarthritis.

Level of evidence: Level IV, case series.

超声引导下囊包膜神经阻滞和补充粘胶治疗髋关节骨关节炎的疼痛缓解和功能改善：回顾性病例系列。

目的：髋关节骨性关节炎是一种常见的慢性疾病，主要影响老年人，其特点是疼痛、关节僵硬和活动受限。对于无法接受全髋关节置换术的髋关节骨性关节炎患者，超声引导下的髋关节周围神经群（PENG）阻滞结合粘弹性补充剂可改善症状。本研究旨在评估髋关节骨性关节炎患者在接受 PENG 阻滞联合粘弹剂治疗后的疼痛和功能情况：本研究对 17 名连续接受超声引导 PENG 阻滞联合粘弹剂治疗的髋关节骨关节炎患者（12 名女性；5 名男性）进行了回顾性研究。主要结果是使用视觉模拟量表（VAS）评估疼痛，并在手术前和手术后 12 周使用西安大略和麦克马斯特大学骨关节炎指数（WOMAC）测量功能。次要结果是并发症发生率：平均年龄（76.5±8.3）岁，标准差（63-93）岁。平均 VAS 显著降低了 3.6 点（P超声引导下 PENG 阻滞联合粘弹剂治疗显示，髋关节骨性关节炎患者在随访 12 周后疼痛和功能得到改善，且无重大并发症：证据级别：IV级，病例系列

期刊介绍： International Orthopaedics, the Official Journal of the Société Internationale de Chirurgie Orthopédique et de Traumatologie (SICOT) , publishes original papers from all over the world. The articles deal with clinical orthopaedic surgery or basic research directly connected with orthopaedic surgery. International Orthopaedics will also link all the members of SICOT by means of an insert that will be concerned with SICOT matters. Finally, it is expected that news and information regarding all aspects of orthopaedic surgery, including meetings, panels, instructional courses, etc. will be brought to the attention of the readers. Manuscripts submitted for publication must contain a statement to the effect that all human studies have been approved by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted. Reports of animal experiments must state that the "Principles of laboratory animal care" (NIH publication No. 85-23, revised 1985) were followed, as well as specific national laws (e.g. the current version of the German Law on the Protection of Animals) where applicable. The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or for failure to fulfil the above-mentioned requirements.
