Hip arthroplasty has become an essential method for treating hip fractures, osteonecrosis of the femoral head, and other diseases. The operation involves a wide range of tissues, and most patients have severe pain after the operation. Therefore, effective perioperative analgesia is helpful for patients to carry out the early functional exercise, reduce bed rest time, and reduce the risk of adverse events such as lower limb deep venous thrombosis and pulmonary embolism. In recent years, ultrasound-guided peripheral nerve block has become an important part of multimodal analgesia. Ultrasound-guided S-FICB has become a widely used nerve block method for analgesia in hip arthroplasty. Ultrasound-guided S-FICB can not only effectively spread local anesthetic (LA) in the fascia iliaca compartment (FIC) but also improve the success of the block of the femoral nerve (FN), lateral femoral cutaneous nerve (LFCN) and obturator nerve (ON). And it provides significant analgesia for the proximal femur. It can effectively reduce perioperative pain, obviously reduce postoperative opioids and shorten the length of hospital stay [
