Pericapsular nerve group block: a 3D CT scan imaging study to determine the spread of injectate
Authors' conclusion
Our study suggests that the analgesic effect of the PENG block may be related to the block of the branches of the femoral nerve traveling within the iliopsoas muscle without a spread pattern commensurate with the block of the obturator nerve.
Study context
- Population
- Patients scheduled for hip surgery
- Participants
- 10 patients
- Outcome
- Spread of injectate (3D CT reconstruction of dispersion)
- Follow-up
- After completion of the block
Methodological detailsimaging study, 3D CT reconstruction

Main finding
As reported in the abstract
Injectate spread on CT
- Injectate mainly confined to the epimysium of the iliacus and psoas muscle, minor spread to the hip capsule
- Contrast dye within the iliacus and/or psoas muscle in all patients
- No spread to the subpectineal plane or the obturator foramen
