Study Notes
Forearm Bones
- The radius is more mobile and shorter than the ulna.
Articulations
- The radius articulates with the capitulum of the humerus to perform flexion/extension.
- The radius articulates with the notch of the ulna to perform rotation (pronation/supination).
Boney Processes
- The radius has a boney process called the Radial Styloid.
- The radius has a boney process called Lister's Tubercle.
- The ulna has a boney process called the Styloid Process.
- The ulna has a boney process that projects distally off the ulnar head.
Joints
- The radius articulates with the base of the radius to form the distal radioulnar joint.
Boney Landmarks
- The ulna has a boney process called the Coronoid Process.
- The radius has a boney process that projects distally off the distal end of the lateral radius.
Forearm Structure
- The ulna is longer than the radius.
- The ulna has a stabilization role in the forearm.
Connective Tissue
- The interosseous membrane is the connective tissue band between the ulna and radius.
Ulnar Landmarks
- The olecranon is the bony eminence located on the proximal end of the ulna.
- The trochlear notch is located on the proximal end of the ulna and forms the elbow joint.
Functional Roles
- The interosseous membrane provides stability to the forearm.
- The ulna acts as a stabilizer in the forearm.
Palpation
- The radial notch is located on the proximal end of the ulna.
- The radial head should be palpated with the patient's arm in flexion.
- Lister's tubercle should be palpated on the dorsal surface of the radius.
- The radial styloid process should be palpated with the patient's arm in radial deviation.
Other
- The radial tuberosity is located on the medial surface of the radius and should be palpated during rotation.
- The shaft of the radius is located in the middle of the forearm.
- The radial neck is located proximally along the shaft of the radius.
