1. CLASSIFICATION: non-axial, gliding
2. ARTICULATING SURFACES
- Proximal: capitulum and capitulotrochlear groove of humerus
- Distal: concave head of radius and small portion of the rim of the radius
3. MOVEMENTS: flexion/extension
- Plane: sagittal
- Axis: medial/lateral
(1.) In full extension there is no contact between the capitulum and the radial head.
(2.) In full flexion the rim of the radial head slides into the capitulotrochlear groove and touches the radial fossa.
