Satoshi Kobayashi; Keiichi Okada; Kimio Onoda; Satoru Horikoshi

A case of a 61-year-old man with ossification of the cervical ligamentum flavum is reported. The ossification was located on the left side of C3-4. The symptoms improved with laminectomy and resection. Ossification of the ligamentum flavum usually occurs in the lower thoracic spine, and is rare in the cervical region. Including the present one, only eight cases have been reported to our knowledge. The clinical features and pathogenesis are discussed.
