The Role of Nerve Blocks in Postoperative Pain Management Following Orthopedic Surgery: A Narrative Review of Techniques, Efficacy, and Long-Term Outcomes

Background Effective postoperative pain management remains a critical component of orthopedic care, as inadequate analgesia is associated with delayed recovery, increased complications, and prolonged opioid use. Objective This narrative review aims to evaluate the role of peripheral nerve blocks in postoperative pain management following orthopedic surgery, focusing on techniques, efficacy, safety, and long-term clinical outcomes. Methods A comprehensive narrative review of the literature was conducted using major databases, including PubMed, Scopus, and Web of Science. Relevant studies, including randomized controlled trials, systematic reviews, and clinical guidelines, were analyzed. Results Peripheral nerve blocks consistently demonstrate superior analgesic efficacy compared to systemic analgesia, with significant reductions in pain scores and opioid consumption. Techniques such as adductor canal and fascia iliaca blocks provide effective, motor-sparing analgesia that facilitates early mobilization. Continuous nerve block approaches further extend analgesic duration and improve postoperative outcomes. Complication rates remain low, particularly with the use of ultrasound guidance, although risks such as local anesthetic systemic toxicity and nerve injury require careful consideration. Conclusion Peripheral nerve blocks represent a highly effective and evolving modality in orthopedic postoperative pain management. Their integration into multimodal analgesia and enhanced recovery pathways improves patient outcomes while minimizing opioid-related risks.
