Pericapsular Nerve Group (PENG) Block for Hip Fracture

Area of Science:

• Anesthesiology
• Pain Medicine
• Regional Anesthesia

Background:

• Fascia iliaca and femoral nerve blocks are common for hip fracture pain.
• These blocks offer opioid-sparing effects and reduce opioid-related adverse events.
• Recent anatomical studies identified key hip innervation landmarks.

Purpose of the Study:

• To describe a novel ultrasound-guided technique for blocking hip articular nerves.
• To introduce the PEricapsular Nerve Group (PENG) block for hip pain management.

Main Methods:

• Development of a new ultrasound-guided technique based on anatomical findings.
• Targeting hip articular branches of the femoral and accessory obturator nerves.
• Application of the PENG block in five consecutive hip fracture patients.

Main Results:

• Successful implementation of the novel PENG block technique.
• Demonstration of the technique's application in a small patient cohort.
• Potential for improved hip pain management and reduced opioid requirements.

Conclusions:

• The PEricapsular Nerve Group (PENG) block is a feasible ultrasound-guided technique for hip innervation blockade.
• This novel approach may provide an effective alternative for hip fracture pain management.
• Further research is warranted to evaluate the efficacy and safety of the PENG block.
