The timing of surgery for hip fractures is crucial for elderly patients. The mortality rate for elderly patients after hip fracture is high, and anesthetic decisions significantly affect the patient's outcome. Regional anesthesia has been shown to have better outcomes than general anesthesia. We proposed a newly developed modified position for the ultrasound-guided combined anterior lumbar and lateral sacral plexus block technique that offers benefits, including minimizing interference with circulation and anesthesia, avoiding position change and pain, and providing effective postoperative analgesia.

The increasing proportion of elderly patients requiring surgery, particularly for hip fractures, is common among the elderly. The timing of surgery for hip fractures is crucial and most require surgical treatment. The mortality rate for elderly patients after hip fracture is high, and anesthetic decisions significantly affect the patient's outcome. Elderly patients have decreased physiological function and are more susceptible to postoperative complications, such as delirium, constipation, pressure sores, and catheter-related infections. Regional anesthesia has been shown to have better outcomes than general anesthesia. We proposed a newly developed modified position for the ultrasound-guided combined anterior lumbar and lateral sacral plexus block that offers benefits, including minimizing interference with circulation and anesthesia, avoiding position change and pain, and providing effective postoperative analgesia. The study validates the feasibility and effectiveness of this technique for elderly hip fracture surgery and compares it with a traditional lumbar-sacral plexus nerve block, providing a fresh perspective on anesthesia for this type of surgery.
