One of the complications inherent in TDR is the possibility of vertebral body fracture due to trauma or a malpositioned implant. The resulting dilemma is that posterior decompression of the displaced bone fragment could then have a destabilizing effect and possibly require fusion, thus obviating the benefit of an arthroplasty procedure. In this study, the authors describe the technical considerations and feasibility of the treatment of a postoperative L-5 paresis that resulted from a dislocated bone fragment at L4\u20135 during a 2-level lumbar TDR.<\/jats:p>","DOI":"10.3171\/2015.11.focus15492","type":"journal-article","created":{"date-parts":[[2016,2,1]],"date-time":"2016-02-01T03:36:55Z","timestamp":1454297815000},"page":"E8","source":"Crossref","is-referenced-by-count":11,"title":["Transforaminal endoscopic decompression of a postoperative dislocated bone fragment after a 2-level lumbar total disc replacement: case report"],"prefix":"10.3171","volume":"40","author":[{"given":"Ralf","family":"Wagner","sequence":"first","affiliation":[{"name":"Ligamenta Spine Centre, Frankfurt am Main, Germany;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Menno","family":"Iprenburg","sequence":"additional","affiliation":[{"name":"Spine Clinic Iprenburg, Veenhuizen, The Netherlands; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Albert E.","family":"Telfeian","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Rhode Island Hospital, The Warren Alpert Medical School of Brown University, Providence, Rhode Island"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-focus15492","series-title":"SAS J","first-page":"8","article-title":"The first 18 months following food and drug administration approval of lumbar total disc replacement in the United States: reported adverse events outside an investigational device exemption study environment","volume":"1","author":"Blumenthal","year":"2007"},{"key":"b2-focus15492","series-title":"Int J Spine Surg","first-page":"10","article-title":"Indications for lumbar total disc replacement: selecting the right patient with the right indication for the right total disc","volume":"8","author":"B\u00fcttner-Janz","year":"2014"},{"key":"b3-focus15492","series-title":"Spine (Phila Pa 1976)","first-page":"E508","article-title":"Percutaneous endoscopic approach for highly migrated intracanal disc herniations by foraminoplastic technique using rigid working channel endoscope","volume":"33","author":"Choi","year":"2008"},{"key":"b4-focus15492","series-title":"J Spinal Disord Tech","first-page":"334","article-title":"Removal of the Charit\u00e9 lumbar artificial disc prosthesis: surgical technique","volume":"22","author":"de Maat","year":"2009"},{"key":"b5-focus15492","series-title":"J Neurosurg Spine","first-page":"143","article-title":"Neurological complications of lumbar artificial disc replacement and comparison of clinical results with those related to lumbar arthrodesis in the literature: results of a multicenter, prospective, randomized investigational device exemption study of Charit\u00e9 intervertebral disc.
