Ultrasound-Guided Identification of Quadrangular Space: Live Demo

Introduction: What is the Quadrangular Space?

The quadrangular space, also referred to as the quadrilateral space, is a critical anatomical region in the posterior shoulder. This space contains the axillary nerve and the posterior circumflex humeral artery, both of which are key targets in ultrasound-guided pain interventions for chronic shoulder pain and denervation procedures.

Understanding this space is crucial for pain physicians, physiatrists, anesthesiologists, and sports medicine specialists interested in shoulder denervation by ultrasonography.

Why Is the Quadrangular Space Important in Pain Medicine?

In the field of interventional pain management, the quadrangular space serves as a window to visualize and access the axillary nerve under ultrasound. This nerve is involved in various shoulder pathologies such as:

• Axillary nerve entrapment

• Quadrilateral space syndrome

• Chronic shoulder pain

• Post-surgical shoulder neuropathies

The precise identification of this space can facilitate diagnostic nerve blocks, therapeutic injections, and ultrasound-guided denervation techniques with high accuracy and minimal complications.

Live Demonstration by Dr. Chinmoy Roy: Quadrangular Space Under USG

In an exclusive ultrasound-guided pain training session at Asian Pain Academy, Dr. Chinmoy Roy demonstrates the real-time identification of the quadrangular space under ultrasound. This practical, anatomy-focused video highlights:

• Probe positioning and orientation to visualize the posterior shoulder

• Key landmarks: Teres minor (superior), Teres major (inferior), long head of triceps (medial), and surgical neck of humerus (lateral)

• Real-time visualization of the axillary nerve under ultrasound

  
  

Applications of Axillary Nerve Blocks and Shoulder Denervation

Using the quadrangular space under ultrasound allows targeted delivery of local anesthetics or neurolytic agents to the axillary nerve, which can be beneficial in:

• Shoulder arthritis

• Rotator cuff tear-related pain

• Post-traumatic or post-surgical neuropathic shoulder pain

• Quadrilateral space syndrome treatment

• Selective denervation procedures for chronic shoulder dysfunction

This technique improves diagnostic clarity, provides therapeutic benefit, and can reduce the need for more invasive surgical interventions.

Asian Pain Academy: Leading the Way in Ultrasound-Guided Pain Interventions

At Asian Pain Academy, we specialize in advanced training for pain physicians through live demonstrations, structured modules, and hands-on workshops. Our focus on ultrasound-guided interventional pain procedures, including techniques like identifying the quadrangular space under USG, empowers physicians to expand their procedural skills with confidence.

Dr. Chinmoy Roy, a senior faculty member, continues to mentor learners globally with real-time guidance in techniques such as axillary nerve identification under ultrasound and shoulder denervation using ultrasonography.
