Elbow joint complex

What you will learn

• Describe the three articular components of the elbow and their means of union.
• Identify capsular attachments, synovial recesses, and ligament systems.
• Relate their organization to movement, stability, blood supply, and innervation.
• Identify the imaging modalities and main groups of disorders listed for the elbow.

Course outline

1. The elbow between arm and hand

   An orientation map of the joint complex linking the arm, forearm, and direction of the hand.

   6 min

2. The three joints combined at the elbow

   Classification and bony partners of the humeroulnar, humeroradial, and proximal radioulnar components.

   8 min

3. Humeral, ulnar, and radial articular surfaces

   Precise matching of the trochlea, capitulum, ulnar notches, and radial-head surfaces.

   20 min

4. Capsule, synovium, and gliding structures

   Fibrous capsular attachments, synovial recesses, and bursae facilitating periarticular gliding.

   14 min

5. Medial and lateral collateral ligaments

   Origins, insertions, and orientation of the collateral bundles stabilizing both sides of the elbow.

   18 min

6. Additional ligaments and elbow stability

   Anterior, posterior, annular, and quadrate ligaments complemented by stabilizing tendons.

   20 min

7. Movements and axes of the elbow and forearm

   Planes, axes, ranges, and muscles of flexion-extension and pronation-supination.

   18 min

8. Blood supply and innervation of the elbow

   Periarticular arterial anastomoses and the distribution of articular nerves between anterior and posterior aspects.

   9 min

9. Imaging and clinical implications

   Imaging modalities and groups of conditions affecting the bones, ligaments, tendons, bursae, and nerves of the elbow.
