PENG block plus local infiltration analgesia for anterior-approach hip replacement

PENG 360°: PENG Block + LIA Nella Endoprotesi di Anca Con Accesso Anteriore.

Not applicable Interventional ASST Gaetano Pini-CTO · NCT07239817

This test sees if a motor-sparing PENG block combined with local infiltration around the hip controls pain as well as spinal anesthesia for adults having anterior‑approach hip replacement.

What this trial studies

This randomized comparison assigns adults having anterior‑approach hip endoprosthesis to either an ultrasound‑guided anterior/posterior PENG block combined with local infiltration analgesia (LIA) or to standard spinal anesthesia. The PENG+LIA arm uses targeted pericapsular sensory injections (A‑PENG and PONG) and a 360° LIA protocol intended to provide surgical anesthesia without major motor blockade. Primary outcomes include pain scores over the first 48 hours and time to first mobilization, with secondary outcomes capturing nausea and other side effects. The aim is to determine whether pain control is similar while allowing earlier leg movement and rehabilitation.

Who should consider this trial

Good fit: Adults (≥18) scheduled for hip endoprosthesis for a femoral fracture via the anterior surgical approach who can give informed consent and have no contraindications to local anesthetics.

Not a fit: Patients with prior major surgery or an existing prosthesis on the same hip, known allergy to local anesthetics, infection at the planned injection site, ASA class > IV, or those who require intraoperative opioids or conversion to general anesthesia are excluded and unlikely to benefit.

Why it matters

Potential benefit: If successful, this approach could provide comparable pain relief with less leg weakness, enabling earlier walking and potentially fewer anesthesia‑related side effects.

How similar studies have performed: Smaller studies and case series of PENG and other motor‑sparing regional techniques have reported promising analgesia and preserved motor function, but randomized comparisons of PENG+LIA versus spinal anesthesia are still limited.
