Unusual cause of foot pain: Brachymetatarsia
The present case has been reported in the Indian Journal Rheumatology.

A 33-year-old male presented with pain in both feet for the last 3 months. There was no fever, stiffness, or swelling. On examination, there was no warmth or tenderness. Fourth and fifth toes on both sides were short, with the left side being shorter. Plain radiograph of both feet was obtained. His blood investigations including rheumatological profile were unremarkable.

On the plain radiograph, the fourth and fifth metatarsals appeared short on both sides, with the left side being shorter. There was no erosion/bony destruction. Later, the patient revealed that his father as well as grandfather had similar short toes. He has been advised footwear modification and review after 6 weeks.

Brachymetatarsia is an uncommon condition in which one of the metatarsals is abnormally short. This usually involves the fourth toe and is often bilateral. If it affects more than one toe, the condition is called brachymetapody. Short first metatarsal, a less common form of brachymetatarsia, is known as Morton's foot.
