Anterior Humeral Line

Summary:

  • The anterior humeral line is a radiographic line that is drawn down the anterior margin of the humerus and through the middle third of the capitellum.
  • It is used along with the radiocapitellar line when assessing for the presence of a radial head fracture or dislocation at the elbow or for the presence of a supracondylar fracture.

    How to Make Line

    While looking at a lateral elbow radiograph (x-ray), the anterior humeral line is made by:

    • Drawing a line down along the anterior margin of the humerus

    • It should pass through the middle 1/3 of the capitellum

    Clinical Application

    The anterior humeral line is one of several radiographic methods or lines used while reading a lateral elbow radiograph (x-ray) and is used to:

    • Assess for the presence of a supracondylar fracture (fracture of the distal humerus)
    • In conjunction with the radiocapitellar line to assess for the presence of a radial head fracture or dislocation at the elbow.
