This cross-sectional human anatomy atlas of the lower limb is an interactive tool based on MRI axial images of the human leg.

Anatomical structures of the lower limb (hip, thigh, knee, leg, anke and foot) and specific regions (compartment of the lower limb) are visible on dynamic labeled umages

Cross-sectional anatomy: MRI of the lower limb

A magnetic resonance imaging (MRI) was performed on a healthy subject; with an axial spin-echo T1 weighted acquisition of the entire human leg.

From a PACS (Picture Archiving and Communicating System), data and DICOM images were exported as JPEG images. The images were resized and colors were added with Adobe Photoshop. Adobe Animate allowed us to develop an atlas-based application with an amazing features and user-friendly interface in order to explore the human skeleton anatomy.

This module is a comprehensive and affordable learning tool for medical students and residents and especially for physicians, anatomists, rheumatologists, orthopedic surgeons and radiologists. It is also an essential communication support to teach patients anatomy and pathology.

Access to an atlas with images in the axial planes, allowing the user to learn and review orthopedic anatomy interactively. The images were labeled, providing an invaluable teaching resource.

We used the Terminologia Anatomica to create the anatomical labels. This terminology is the international standard on human anatomy (it replaces the previous standard, Nomina Anatomica since 1998). It was developed by the Federative Committee on Anatomical Terminology (FCAT) and the International Federation of Associations of Anatomists (IFAA).

Anatomy of the lower limb (hip, thigh, knee, leg, ankle and foot): how to visualize anatomic labels

The horizontal menu gives access to groups of anatomical structures that can be chosen by the user:

  • Arteries
  • Veins
  • Muscles
  • Ligaments
  • Tendons
  • Bones
  • Nerves

 

Cross section of the leg : muscular compartment, bones (tibia, fibula) and muscles

As the cursor is moved over a particular compartment of the lower thigh or the leg, that compartment is highlighted and labelled: anterior, medial, lateral or posterior compartment.

The vertical left menu provides an illustration of a lower limb skeleton based on a three dimensional (3D) model that simplifies access to the anatomical regions.

The test mode allows comprehensive evaluation of user progress.
