The Growing Courses of Ossification of Posterior Longitudinal Ligament(OPLL) in the Cervical Spine about Post Operative Cases.

Abstract

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.

A Patient With Two Re-surgeries for Delayed Myelopathy Due to Progression of Ossification of the Posterior Longitudinal Ligaments After Cervical Laminoplasty

“…[1][2][3][4][5][6][7][8][9] A few patients whose neurologic manifestation worsened by OPLL progression have been reported, and there was unexpectedly little influence of OPLL progression on postoperative results. There have been only a limited number of studies on patients who underwent resurgery after posterior decompression, such as laminoplasty and laminectomy because of the recurrence of symptoms.…”
