Idiopathic Avascular Necrosis of First Metatarsal Head in a Pediatric Patient.

Abstract

Idiopathic avascular necrosis of the first metatarsal head rarely occurs in pediatrics. The present case of avascular necrosis of the first metatarsal head occurred in a 13-year-old male who came to the clinic with a 9-month history of pain in the first metatarsophalangeal joint. Conservative treatment had been applied for 9 months, but the pain had not been relieved. Therefore, surgical treatment, including decompression and debridement, was performed in the first metatarsal head of the patient. After 6 months of follow-up monitoring, full range of motion of the first metatarsophalangeal joint was observed, and the pain had disappeared. No any other complications had developed during 18 months of follow-up monitoring.
