THR (Total Hip Replacement) can be very painful and regional anesthesia is very effective in reducing postoperative pain. Erector Spinae Plane Block (ESPB) and PENG (pericapsular nerve group block) are alternative approaches to the hip sensitive nerve branches that resulted to be very promising for hip surgeries. However, no studies investigated the analgesic superiority of either PENG or ESPB. In our study the investigators compare PENG (with a lateral femoral cutaneous nerve block) and ESPB in terms of pain relief expressed as morphine consumption in the first 24 hours after primary THR.
