This study investigated the safety, effectiveness, and clinical and radiological outcomes of @entity2649 ( @entity2649 ) for recurrent @entity890 (rLDH) following previous lumbar spine surgery. Seventy-three consecutive @entity1 treated for rLDH between June 2005 and May 2012 were included in the study. The previous surgical procedures included percutaneous discectomy, discectomy with laminotomy, discectomy with unilateral laminectomy, and discectomy with bilateral laminectomy. The level of rLDH was L4-L5 in 51 @entity1 , L5-S1 in 19 @entity1 , and L3-L4 in three @entity1 . All @entity1 underwent reoperation using the @entity2649 technique. Outcomes were evaluated using the Oswestry disability index (ODI), visual analogue scale (VAS) scores for @entity1643 and @entity158 , and the Japanese Orthopaedic Association (JOA) score, based on the results of physical examinations and questionnaires. The range of motion and disc height index of the operative segment were compared between preoperative and postoperative radiographs. The mean follow-up period was 4.1years. The VAS scores for @entity1643 and @entity158 , ODI, and JOA score improved significantly between the preoperative and final follow-up evaluations. The mean recovery rate of the JOA score was 89.0%. The disc space height and stability at the fused level were significantly improved after surgery. The fusion rate at the final follow-up was 93.2%. There were no major complications. These results indicate that @entity2649 can be considered an effective, reliable, and safe alternative procedure for the treatment of rLDH.

Four-year follow-up results of @entity2649 as revision surgery for recurrent XXXX after conventional discectomy.
