Ossification of the posterior longitudinal ligament (OPLL) is no longer only a Japanese disease. In 2004, 18 papers on OPLL and related conditions were published, and 7 of those were from countries other than Japan. Major textbooks on spine surgery, such as The Spine, The Cervical Spine, and Spine Surgery, have devoted chapters to OPLL.
