Is this trial a fit for you?

Likely a good fit

Adults aged 65 and older undergoing elective or emergency hip surgery, without contraindications to regional anesthesia or ropivacaine, and able to provide pain scores.

Probably not a fit

Patients with contraindications to regional anesthesia, chronic opioid use, cognitive impairment precluding reliable assessment, or severe hepatic/renal impairment may derive less or no benefit.

What this trial studies

This randomized, three-arm trial compares postoperative analgesia strategies in older adults undergoing hip surgery. Participants are assigned to receive either the PENG block alone, the PENG block plus periarticular injection, or periarticular injection alone. The goal is to determine which approach provides superior pain relief without compromising motor function, enabling earlier mobilization and potentially reducing opioid use and related complications. The study focuses on patients 65 years and older with hip procedures and standard ASA I-III status, using structured pain assessments and safety monitoring. Recruitment and execution are centered at Poznan University of Medical Sciences in Poland.

Why it matters

Potential benefit: If successful, the approach showing the best balance of analgesia and motor preservation could improve recovery and reduce opioid-related complications after hip surgery.

How similar studies have gone: Early data suggest PENG blocks may improve analgesia, but direct comparisons with periarticular injections and combination therapy require testing; this trial addresses that gap.
