Persistent chest pain or fuzzy back pain

Patients with ossification of the posterior longitudinal ligament of the thoracic vertebrae complain of persistent ambiguous back pain, and their history can last from months to years. Kenji Hannai reported that 12 patients who had undergone anterior surgery had complained of persistent chest pain or fuzzy back pain. Osteosclerosis of the posterior longitudinal ligament (OPLL) is not a common disease worldwide, but it is not uncommon to see hospitals in some countries in the Far East due to ossification of the posterior longitudinal ligament and paralysis of the limbs.
