Anaesthesia · Regional anaesthesia: PENG block for hip fracture

Sample item

A pericapsular nerve group (PENG) block is increasingly used in hip fracture. What is its main advantage?

AIt produces complete motor block of the legBIt targets the sensory branches to the anterior hip capsule while sparing motor function of the quadricepsCIt replaces the need for any other analgesia in all patientsDIt anaesthetises the sciatic nerve

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. It targets the sensory branches to the anterior hip capsule while sparing motor function of the quadriceps

The PENG block deposits local anaesthetic near the iliopubic eminence, blocking articular branches of the femoral, obturator and accessory obturator nerves to the anterior hip capsule. It provides good analgesia while largely preserving quadriceps strength, which helps early mobilisation. It is used in the emergency department and perioperative setting.

Option by option

A. It produces complete motor block of the leg
It is designed to avoid dense motor block.
B. It targets the sensory branches to the anterior hip capsule while sparing motor function of the quadriceps (correct)
Correct. Capsular analgesia with preserved motor power is its advantage.
C. It replaces the need for any other analgesia in all patients
Multimodal analgesia is still required.
D. It anaesthetises the sciatic nerve
It does not block the sciatic nerve.
