Where is the joint line located for the ‘Elbow Joint’ (humero) ?
The joint line is located below the Trochlea and runs along to the Capitulum.
Where is the Joint Line for the Superior Radio- Ulnar Joint?
The joint line runs from the medial aspect to the lateral aspect of the Radial Head.
Where is the Joint Line for the Inferior Radio-Ulna Joint located?
The joint line is a vertical line the runs from the medial aspect to the lateral aspect of the ulna styloid process.
What are the articular surfaces of the Humero-Radial Joint?
Capitulum of the Distal Humerus
Proximal Head of the Radius
What are the articular surfaces of the Humero- Ulnar Joint ?
Trochlea of Distal Humerus
Trochlear Notch of Proximal Ulna
List the ligaments of the Elbow Joint
Medial Collateral
Lateral Collateral
Annular
Quadrate
Describe the passage of the Medial Collateral Ligament
The Medial Collateral Ligament fans out from the Trochlea and has anterior, posterior and intermediate portions inserting into the medial aspects of the coronoid process and the olecranon.
Describe the passage of the Lateral Collateral Ligament
Single triangular band that runs from the capitulum to annular ligament.
Describe the Annular Ligament
A radial notch on Ulna to Radial Head, the inner surface is lined with fibrocartilage.
Describe the Quadrate Ligament
The inferior border of the radial notch to the neck of the radius.
Name the soft tissue of the Elbow Joint.
Interosseous Membrane
Describe the Interosseous Membrane
Serves as an attachment for the deep muscles and stabilises the radius and ulna.
