Lister's tubercle or dorsal tubercle of radius is a bony prominence located at the distal end of the radius.

Lister's tubercle is found on the dorsal distal radius.

[4] Lister's tubercle serves as a pulley for the tendon of extensor pollicis longus, which wraps around the medial side and takes a 45° turn.

[1] Hyperextension of the wrist can lead to fracture of Lister's tubercle, as pressure is increased from the extensor pollicis longus tendon.

[7] An "island-shaped" fracture can also expose the tendon to a rough edge and lead to tendon rupture (usually long after the initial fracture).
