Study Notes
Elbow Anatomy and Function
- The normal valgus carrying angle for females is approximately 5-7°.
- The radiohumeral articulation is a type of hinge joint.
- The sublime tubercle is located on the medial aspect of the humerus, just above the medial epicondyle.
- In an extended elbow, only about 20-30% of the weight is transmitted through the ulnohumeral joint.
- The normal functional range of motion (ROM) for flexion/extension at the elbow is 0-140° to 150°.
