title: Extensor digitorum longus tenosynovitis caused by talar head impingement in an ultramarathon runner: a case report.
abstract: Stenosing tenosynovitis of the extensor digitorum longus tendon is an injury related to ultramarathon running. A 32-year-old male ultramarathon runner developed chronic tenosynovitis of the ankle dorsiflexors. He was diagnosed with extensor digitorum longus tenosynovitis caused by talar head impingement associated with exostosis. He failed to respond to non-operative management and decided to undergo tenosynovectomy of the extensor digitorum longus tendon. The pain was relieved without functional disturbance of the foot and ankle, and the patient returned to running 3 weeks postoperatively. At the 2-year follow-up, he was participating fully in ultramarathons.
