A Suprainguinal Ultrasound-Guided Fascia Iliaca Plane Injection Using the Anterior Inferior Iliac Spine Landmark: An...

Area of Science:

• Anesthesiology
• Pain Medicine
• Medical Imaging

Background:

• The fascia iliaca compartment offers a potential space for regional anesthesia.
• Suprainguinal approaches are anatomically advantageous for cephalad spread.
• Standardized ultrasound-guided techniques for this approach are limited.

Purpose of the Study:

• To describe an anatomy-based, ultrasound-guided suprainguinal fascia iliaca plane injection.
• To utilize the anterior inferior iliac spine (AIIS) as a sonographic landmark.
• To provide a reproducible workflow for clinician training and procedural standardization.

Main Methods:

• Anatomy-based suprainguinal approach using ultrasound guidance.
• Identification of the anterior inferior iliac spine (AIIS) as a sonographic landmark.
• In-plane needle advancement into the fascial plane with test injectate confirmation.

Main Results:

• Detailed sono-anatomical orientation and needle trajectory are described.
• Confirmation of fascial plane separation and injectate spread is emphasized.
• The technique focuses on safety considerations and reproducible workflow.

Conclusions:

• The described AIIS-based ultrasound-guided suprainguinal fascia iliaca injection provides a standardized approach.
• This technical report serves as an educational tool for interventional pain practitioners.
• The workflow aims to support training, standardization, and future clinical studies.
