Welcome to the Toronto Western Hospital Department of Anesthesia and Pain Management Virtual Spine website. This site is intended to be a resource for educators and students looking for tools to facilitate the teaching and learning of Spine Anatomy and Regional Anesthesia of the Spine.

This project was initiated by Dr. Vincent Chan and Dr. Ahtsham Niazi to create interactive online teaching modules to compliment the educational material on Dr. Chan's Ultrasound for Regional Anesthesia Web site.

We have begun the process of converting the modules of the Virtual Spine from Flash to HTML5. We have completed the sections of the Lumbar Spine Ultrasound module for Patient positioning and the Sonoanatomy sections for the Paramedian and Transverse scans of the spine. More sections will be added in 2021 as they are completed.

Ultrasound Guided Regional Anesthesia of the
Lumbar Spine Teaching Module

The Lumbar Spine Ultrasound module is aimed at teaching ultrasound-guided regional anesthesia for the lumbar spine. It includes an animation illustrating the flexion of the lumbar spine during patient positioning to open the intervertebral spaces, facilitating the insertion of needles into the spinal canal.
