Abstract: Fracture surgeries are frequently accompanied by severe pain, necessitating efficacious pain management strategies to enhance postoperative recovery. Nerve block techniques, which are critical in mitigating pain, involve the targeted administration of local anesthetics to disrupt nerve signal transmission, thereby achieving significant analgesia. Traditionally, these techniques rely on anatomical landmarks and the clinician’s expertise, which can introduce variability and potential risks. The adoption of ultrasound-guided nerve blocks has increased, facilitated by advancements in imaging technology. This approach enables precise placement of anesthetics through real-time visualization of neural structures and adjacent tissues, significantly improving the accuracy and safety of the procedure. This review summarizes recent advancements in the application of ultrasound-guided nerve block techniques in fracture surgeries, particularly for rib, upper limb, thoracic, lumbar, and hip fractures. By precisely placing local anesthetics, these techniques not only improve the safety and efficiency of surgeries but also significantly reduce postoperative pain and recovery time. The widespread application of ultrasound-guided nerve blocks offers an efficient and low-side-effect anesthesia management strategy, enhancing post-surgical patient experience and recovery quality.
