title: Spontaneous osteonecrosis of navicular and talus (SONNT).
abstract: We describe a rare case of simultaneous and spontaneous osteonecrosis affecting bilateral navicular and talar bones in a young male. On both sides, there was associated symptomatic talonavicular and naviculocuneiform arthritis. The more symptomatic left foot was managed successfully by talonavicular-cuneiform (TNC) arthrodesis and core decompression of talar body. A probable cause of this rare disorder was most likely due to a developmental anomaly in the preaxial ray of the foot. As no literature is currently available for this rare condition, our case report is intended to provide a referral point for future studies in the early diagnosis and management of this condition.
