PENG Block vs PENG Plus Periarticular Injection vs Periarticular Injection in Older Adults

Pain after hip surgery is common in older adults and may limit early mobilization, increase the need for opioid medications, and contribute to complications such as delirium, nausea, or prolonged hospital stay. Effective postoperative pain management that preserves muscle strength and supports early rehabilitation is especially important in this population. Several analgesic strategies are currently used after hip surgery. Periarticular injection (PAI), administered by the surgeon during the procedure, is commonly used as part of standard care. The pericapsular nerve group (PENG) block is a newer ultrasound-guided regional anesthesia technique that targets the sensory nerves of the hip joint while sparing motor function. It may provide effective pain relief and facilitate early mobilization. However, it is unclear whether PENG block alone is superior to periarticular injection, and whether combining both techniques provides additional benefit. The aim of this randomized controlled clinical study is to compare three postoperative analgesic strategies in older adults undergoing hip surgery: PENG block alone, PENG block combined with periarticular injection, and periarticular injection alone. Participants will be randomly assigned to one of three study groups. The primary hypothesis is that regional anesthesia with a PENG block, either alone or combined with periarticular injection, will provide superior postoperative pain control compared with periarticular injection alone. …
