Radiographic anatomy of the elbow on a CT arthrogram


This anatomy module presents the anatomy of osteo-articular elbow by arthroscanner, conventional radiography and 3D images.

It is specially useful for musculoskeletal imaging specialists (radiologists, rheumatologists, orthopedic surgeons, therapists...).

 

Medical images of the elbow joint

On those images we used the latest medical imaging techniques (335 images with more than 125 anatomical structures labeled):

  • Arthrography: scan of the elbow after opacification by iodinated contrast from the joint cavity of the elbow. Visible in two different windowing scans (bone and soft tissues) and in three different planes (axial, coronal, and sagittal).

 

Elbow joint: Humeroulnar joint, Humeroradial joint, Proximal radioulnar joint, Ulnar collateral ligament, Radial collateral ligament, Anular ligament of radius
Elbow joint

 

  • 3D: 3D bone reconstruction of the elbow bones (humerus, radius and ulna) based on a scan.

 

Humerus : Radius , Ulna
Humerus : Radius , Ulna

 

  •  Arthrography: shows the positioning of the catheter within the joint cavity prior to opacification then plates of front and side views of the elbow joint by arthrography.

Labeled anatomical structures of the elbow

125 anatomical structures of the elbow were labeled, accessible on "Anatomical parts":

  • Bones: the different parts of the humerus, the ulna and radius at the level of the elbow.
  • Joints: the different structures of the elbow joint and the joint cavity visible in the elbow arthrogram (synovial folds, synovial villi).
  • Ligaments: the main ligaments of the elbow (radial and ulnar collateral ligaments, annular ligament of the radius).
  • Muscles / tendons: the different muscles and tendons of the ulnar region of the forearm and arm, especially the muscles arising from the tendon common to the extensors and flexors.
  • Fascias / synovial bursa: the radioanatomy of the brachial and antebrachial fascia, intermuscular septa and the different synovial bursa (olecranon bursa, cubital bursa).
  • Artery: the division of the brachial artery in the ulnar and radial arteries at the cubital fossa.
  • Veins: the superficial (cephalic and basilica veins, venous M of the anterior cubital region) and the deep venous networks (radial, ulnar and brachial veins)
  • Lymph nodes: the scan location of the ulnar nodes
  • Nerves: the nerve pathways in the cubital region and the ulnar cutaneous innervation (radial nerve, ulnar nerve, medial and lateral cutaneous nerves, median nerve...).

Anatomical parts

On "Anatomical parts" the user can choose to show or hide all the anatomical labels of the cubital region or to display only the most important anatomical structures avoiding an overload of the images.

Contrast

On "Contrast" the user can select to display the bony structures and the joint cavity or soft tissue (muscles, tendons).

Anatomical terminology

The anatomical structures were labeled by Antoine Micheau M.D. (Radiologist, Montpellier – France), using the Terminologia Anatomica.
