The purpose of this paper is to describe when the growing of OPLL starts after operations. We studied radiograms of 68 patients who were operated on for myelopathy with OPLL. There were 52 males and 16 females. Duration of follow-up study varied from one year to 15 years, the average being four years.The main results found in this study were as follows. 1) The growing courses of OPLL after operations were deviled into four classes.2) In 33 patients (50%), the growing of OPLL started immediately after operations. 3) They might be the growing states of OPLL before operations.
