OBJECTIVE: With the objective to present the clinical picture of three cases with this complication and analyze methodologically the works present in the bibliography. METHOD: Three operated patients of lumbar column that received a circumferential arthrodesis and presented in postoperative remote a new symptomatology related to the migration of one or of both PLIF. RESULTS: It was made by means of the boarding by retroperitoneal previous route, for discectomy, retirement of migrated material and positioning of a previous intersomatic device. In the first case It was associated a later boarding for the retirement of the osteosynthesis material. A bibliographical search was made to analyze the data on the retirement according to parameters of scientific evidence. CONCLUSIONS: Publications of Evidence type 1 or 2 do not exist that mark clear orders. The presence of post-surgical fibrosis would orient to the boarding by previous route in the retirement of the intersomatic devices and thus to avoid the injuries of the dural coat and the radicular stretching. The difficulty of the vascular handling and the risk of retrograde ejaculation in patients of male sex are parameters to consider when deciding on the later boarding. The retirement of the PLIF migrated to later that cause painful symptomatology and/or deficit in a practice becomes highly demanding and difficult to handle.
