PENG versus Deep Iliacus Plane block for pain relief in intertrochanteric femur fractures

Comparison of the Analgesic Efficacy of the PENG Block and the Deep Iliacus Plane Block During Positioning for Spinal Anesthesia and in the Postoperative Period in Intertrochanteric Femur Fractures: A Prospective, Randomized Controlled Study

Not applicable Interventional Erzincan Binali Yildirim Universitesi · NCT07513740

This study will see if PENG or Deep Iliacus Plane nerve blocks give better pain relief and make positioning for spinal anesthesia easier for adults having surgery for intertrochanteric hip fractures.

What this trial studies

This is a prospective, single-center, double-blind randomized controlled trial enrolling a minimum of 75 adults aged 30–85 with ASA I–III who are scheduled for elective intertrochanteric femur fracture repair at Erzincan Mengücek Gazi Training and Research Hospital. Participants will be randomized to receive a PENG block, a Deep Iliacus Plane Block (DIPB), or standard intravenous analgesia before spinal anesthesia, with patients and outcome assessors blinded to group assignment. Pain during positioning for spinal anesthesia, postoperative pain scores, opioid consumption, and motor function will be recorded in the immediate perioperative and early postoperative periods. The study will run over a 12-month period after ethics approval and informed consent is obtained.

Who should consider this trial

Good fit: Ideal candidates are adults aged 30–85 with ASA physical status I–III scheduled for elective intertrochanteric femur fracture repair under spinal anesthesia who are not chronic opioid users and have no infection or bleeding risk at the block site.

Not a fit: Patients who are ASA IV or higher, undergoing emergency surgery, with cognitive impairment, chronic opioid use, infection at the injection site, bleeding diathesis, or requiring additional general anesthesia are unlikely to be eligible or to benefit.

Why it matters

Potential benefit: If one block provides superior pain control with less motor blockade, patients could have more comfortable positioning for spinal anesthesia, lower postoperative opioid needs, and faster early recovery.

How similar studies have performed: PENG block has growing evidence as a motor-sparing approach for hip analgesia and small trials show benefit, while the DIPB is newer with limited randomized comparative data, so direct head-to-head evidence is sparse.
