Anatomy of the elbow (MR cross-sectional imaging and 3D medical pictures)


This anatomy module is about radioanatomy of the elbow in an MRI and 3D reconstructions.
It contains 260 MRI slices, 61 3D reconstruction images, with 155 labeled anatomical structures.
This atlas of anatomy is useful especially for radiologists, surgeons, rheumatologists and physicians specializing in musculoskeletal imaging.

Images of the elbow joint in MRI and 3D

The MRI and 3D scanning images of the elbow are from a healthy volunteer. The MRI slices were acquired with a thickness of 4 mm, with different weightings and impacts:

  • T1-weightings and PD-Fat sat: weightings used in clinical routines in musculoskeletal imaging
  • Axial, sagittal and coronal impacts of the cubital area

 

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

 

 The 3D images are from a different source of the MRI ones and are "volume rendering" post-processed from a scan of the elbow.

Labeled anatomical structures of the cubital region

155 anatomical structures of the elbow, and adjacent segments of the arm and forearm were labeled:

  • General anatomy: shows the main areas such as the cubital fossa, the anterior and posterior elbow regions.
  • Bones: item divided into humerus, radius and ulna specifically selectable.
  • Elbow joint: humero-ulnar joint, humeroradial joint and proximal radioulnar joint.
  • Ligaments: principally the radial and ulnar collateral ligaments and the annular ligament of the radius.
  • Muscles / tendons: displays the muscles and tendons of the ulnar region in two different colors.
  • Fascia / aponeuroses: on this MRI of the elbow the brachial fascia, antebrachial fascia and bicipital aponeurosis and the intermuscular septa of the arm are present.
  • Compartments: outline of anatomical zones corresponding to the muscular compartments of the forearm and arm.
  • Synovial bursa: MRI anatomy of tendinous bursa of the elbow joint, notably the olecranon bursa.
  • Arteries: anatomical nomenclature of the brachial, ulnar and radial arteries as well as their collaterals.
  • Veins: anatomy of the superficial (cephalic and basilica veins) and deep (brachial, ulnar and radial veins) venous system.
  • Lymph nodes: supratrochlear and ulnar nodes
  • Nerves: the superficial and deep elbow nerve network is labeled, with a different shade of yellow for each nerve: radial, ulnar, median and cutaneous nerves of the arm and forearm.

Anatomical parts

On "Anatomical parts" the user can choose to show or hide all the anatomical labels or to display only the most important anatomical structures.

Anatomical terminology

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