Anterior Humeral Line

Other Names

Illustration of the anterior humeral line

• Anterior Humeral Line (AHL)

---

Introduction

• Key line demonstrating normal elbow alignment
• Should be used whenever reading a pediatric elbow radiographic to exclude occult supracondylar fracture
• Done on standard lateral view

---

Interpretation

Measurement

• Line drawn down the anterior surface of the humerus should intersect the middle third of the capitellum

Interpretation

• During a FOOSH, radial head impacts capitellum
• Often resulting in a supracondylar fracture with posterior displacement
• Minor displacement can push the humeral line posterior to the capitellum

Exceptions

• In children under 4, the anterior humeral line can pass through the anterior 1/3 of the capitellum
