Hip arthroplasty and endoprosthesis surgery typically utilize general or spinal anesthesia, but regional techniques like the PENG block offer potential analgesic benefits. This report presents three cases in which a modified ultrasound-guided pericapsular infiltration technique is used as the only technique for hip surgery. Three patients undergoing hip arthroplasty/endoprosthesis surgery with different approaches (direct anterior, lateral, and posterolateral) received ultrasound-guided anterior and posterior pericapsular injections (A-PENG and PONG) and additional local anesthetic infiltration tailored to the surgical approach. All patients experienced successful intraoperative anesthesia and adequate postoperative analgesia within 24 hours, with no motor block. The technique was adaptable to different approaches and patient characteristics. This case series suggests the feasibility and potential benefits of the pericapsular nerve blocks as a regional anesthesia option for hip surgery. Further research is needed to compare its efficacy, safety, and cost-effectiveness with other techniques in larger, controlled studies.
