HALLUX RIGIDUS

Hallux rigidus is a unique condition and not simply a type of osteoarthritis.

It generally occurs in middle aged runners, or other sports that involve chronic hyperextension.

Most likely it is a chronic overuse injury related to hyperextension. The imaging features are: • an irregular narrowed joint on the frontal radiograph and •

a large dorsal osteophyte visible on the lateral.

Excision of the osteophytes can improve symptoms.
