class="h4">Purpose

We report on the peculiar case of a patient that experienced pain under the first metatarsal head on the left foot. An attempt is made to establish its etiology.

class="h4">Clinical case

The patient is a 29-year-old woman who experienced pain and intense rapid onset inflammatory signs on the plantar aspect of the head of the first metatarsal on the left foot. Plain films show distal migration of the medial sesamoid bone of the first metatarsophalangeal joint and perisesamoid calcifications. Nuclear magnetic resonance is suggestive of osteonecrosis.

class="h4">Discussion

We review the potential causes of pain under the first metatarsal head in order to carry out a differential diagnosis.

class="h4">Conclusion

The cause of the pain was a rupture of the distal enthesis of the medial bundle of the flexor hallucis brevis at the level of the medial sesamoid, as a result of calcifying tendinitis.
