The use of an interbody cage facilitates spinal fusion. However, complete cage migration into the dura matter rarely occurs and can be challenging to manage. Case Presentation: A 44-year-old man presented at our spine center with a history of incomplete paraplegia and cauda equina syndrome that had lasted for 2 years and 4 months. This condition developed after he underwent six lumbar spine surgeries to address lower back pain and right-sided sciatica. A structural allograft kidney-shaped cage was found completely within the dura at the level of the L3 vertebra. Durotomy, cage retrieval, and pedicle screw fixation from the L2 to L4 vertebrae were performed. Numbness in both lower limbs markedly decreased within several days of the operation. After four months following the progressive physical therapy, the patient could partially control both urination and defecation. Five months postoperatively, he could stand with slight assistance. Conclusions: Complete intradural cage migration is a rare and serious complication. To the best of our knowledge, this is the first reported case with such a condition in the literature. Even if treatment is delayed, surgical intervention may salvage the remaining neurologic function and may even lead to partial recovery.<\/jats:p>","DOI":"10.3390\/medicina59050956","type":"journal-article","created":{"date-parts":[[2023,5,17]],"date-time":"2023-05-17T02:04:05Z","timestamp":1684289045000},"page":"956","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Complete Intradural Interbody Cage Migration in Lumbar Spine Surgery: A Case Report and Literature Review"],"prefix":"10.3390","volume":"59","author":[{"given":"Pang-Hsuan","family":"Hsiao","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, China Medical University Hospital, Taichung 404327, Taiwan"},{"name":"Spine Center, China Medical University Hospital, No. 2, Xueshi Rd., North Dist., Taichung 404327, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erh-Ti","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, China Medical University Hospital, Taichung 404327, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hsien-Te","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, China Medical University Hospital, Taichung 404327, Taiwan"},{"name":"Spine Center, China Medical University Hospital, No. 2, Xueshi Rd., North Dist., Taichung 404327, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuan-Shun","family":"Lo","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, China Medical University Hospital, Taichung 404327, Taiwan"},{"name":"Spine Center, China Medical University Hospital, No. 2, Xueshi Rd., North Dist., Taichung 404327, Taiwan"},{"name":"Department of Orthopedic Surgery, China Medical University Beigang Hospital, Yunlin 651012, Taiwan"},{"name":"Graduate Institute of Precision Engineering, National Chung Hsing University, Taichung 402204, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"67","DOI":"10.1097\/BRS.0b013e31820cccfb","article-title":"Spinal fusion in the United States: Analysis of trends from 1998 to 2008","volume":"37","author":"Rajaee","year":"2012","journal-title":"Spine"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"752","DOI":"10.21037\/jss-20-492","article-title":"Trends in lumbar spinal fusion\u2014A literature review","volume":"6","author":"Reisener","year":"2020","journal-title":"J.
