Radial beak

Last revised by Daniel MacManus on 16 Jun 2021

The radial beak, also known as an epiphyseal spur, is a benign anatomical osseous variation of the distal radius.

Radiographic appearance

The radial beak manifest as a bony protrusion at the lateral aspect of the distal radius along the line of the fused/closing growth plate 1. It is typically pointing proximally.

Significance

As a normal, albeit rare anatomical variation it can be mistaken for a distal radius fracture.
