Abstract

Posterior surgery has been widely used as an initial surgery for cervical ossification of the posterior longitudinal ligament (OPLL). However, some patients require revision surgery because of failure of symptom relief or late neurological deterioration after posterior surgery. The aim of this study is to retrospectively investigated the surgical results and complications of anterior controllable antedisplacement fusion (ACAF) as a revision surgical technique after initial posterior surgery for OPLL. The present study concluded 13 patients. The operation duration, blood loss and hospital stay was estimated. Radiologic assessment included type and extent of OPLL, decompression width and antero-posterior (AP) diameter of the spinal cord. The JOA scoring system was used to evaluate the neurological status. Surgery- and implant-related complications such as cerebrospinal fluid (CSF) leakage, spinal cord or nerve injury, subsidence and pseudoarthrosis were all recorded. The results showed that nine patients undergoing revision ACAF because of residual stenosis after initial posterior surgery, two because of OPLL progression, one because of lamina closure, one because of a blind man requiring better neurological function of both hand...Continue Reading
