Anatomy of Elbow X-rays

Dr. Morton, an anatomist, explains the anatomy of the elbow joint using X-rays. The video covers both the AP and lateral views, detailing the structures visible in each view, such as the medial and lateral epicondyles, the olecranon process, and the radial head. The video also discusses the importance of the anterior humeral line and the radiocapitellar line for assessing elbow alignment, especially in pediatric cases.

What is the significance of the anterior humeral line in elbow X-rays?

• It indicates the presence of a fracture

• It is used to measure the length of the humerus
