Hip fracture: PENG block alone vs PENG with LFCN block for easing spinal anesthesia positioning
Official title: Comparative Study Between Pericapsular Nerve Group Block (PENG) And Pericapsular Nerve Group (PENG) Block Combined With Lateral Femoral Cutaneous Nerve (LFCN) Block for Positioning Analgesia Prior to Spinal Anesthesia in Hip Fracture Patients
Run by Ain Shams University · NCT07687290 · Data updated 2026-11-12
This study tests whether adding an LFCN block to the PENG block helps patients with hip fractures lie still for spinal anesthesia better than the PENG block alone.

Is this trial a fit for you?
✓Likely a good fit
Adults 18-70 with a primary unilateral hip fracture, ASA I-II, scheduled for spinal anesthesia, able to consent.
✕Probably not a fit
Patients with contraindications to regional blocks, coagulopathy, infection at the injection site, or pre-existing lower limb neurologic deficits may not benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Adults with unilateral hip fractures undergo spinal anesthesia and experience intense pain during positioning. The trial compares two regional anesthesia approaches: PENG block alone versus PENG combined with LFCN block, both using local anesthetics. Ultrasound guidance is used to deliver targeted analgesia to improve positioning without significant motor block. Outcomes focus on analgesia quality during positioning and procedural feasibility in the hip fracture population.
Why it matters
Potential benefit: If successful, patients may experience less pain during positioning for spinal anesthesia, potentially making the procedure faster and safer.
How similar studies have gone: Previous studies have shown PENG blocks can provide effective hip analgesia; combining blocks for broader sensory coverage is plausible but not well established.
