However, the associated complications such as implant malposition, loosening, subsidence, implant migration, fractures, and infection may necessitate retrieval of the artificial disc and proceeding with interbody fusion. Retrieval of artificial discs in proximity to important vascular, urological, and other vital anatomical structures (for example, L4\u20135) presents numerous difficulties to spine and approach surgeons. To avoid the impediments of an anterior revision approach, in 2006 Pimenta et al. described an effective transpsoas lateral minimally invasive approach to retrieve the TDR device. In this paper, the authors adopted this technique in their surgical practice; however, they realized that a complex step involved the removal of the polyethylene core. The polyethylene core is compressed between the device endplates and is difficult to remove with the aid of a Kocher clamp as advised by Pimenta et al. Moreover, distraction on the endplates or the vertebral bodies to decrease the compression across the core is laborious, time consuming, and often not possible due to the approach and location of the lumbar plexus. In the present paper, the authors propose a novel modification to the polyethylene core removal with the use of a screw to create a better lever arm, apply effective distraction, and secure a good grip to enable core retrieval. This modification significantly reduced the operating time.<\/jats:p>","DOI":"10.3171\/2010.12.spine09429","type":"journal-article","created":{"date-parts":[[2011,2,23]],"date-time":"2011-02-23T21:21:18Z","timestamp":1298496078000},"page":"466-469","source":"Crossref","is-referenced-by-count":5,"title":["A novel modification for removal of the polyethylene core in artificial disc retrieval using a transpsoas minimally invasive technique"],"prefix":"10.3171","volume":"14","author":[{"given":"Wayne K.","family":"Cheng","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vikram","family":"Jadhav","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel K.","family":"Palmer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-spine09429","series-title":"Orthop Clin North Am","doi-asserted-by":"publisher","first-page":"389","DOI":"10.1016\/j.ocl.2005.03.003","article-title":"Complications and strategies for revision surgery in total disc replacement","volume":"36","author":"Bertagnoli","year":"2005"},{"key":"b2-spine09429","series-title":"J Spinal Disord Tech","doi-asserted-by":"publisher","first-page":"411","DOI":"10.1097\/00024720-200608000-00007","article-title":"Lumbar total disc replacement using ProDisc II: a prospective study with a 2-year minimum follow-up","volume":"19","author":"Chung","year":"2006"},{"issue":"3 Suppl 3","key":"b3-spine09429","series-title":"Eur Spine J","doi-asserted-by":"publisher","first-page":"S439","DOI":"10.1007\/s00586-006-0186-9","article-title":"Total disc replacement in the lumbar spine: a systematic review of the literature","volume":"15","author":"Freeman","year":"2006"},{"issue":"6 Suppl","key":"b4-spine09429","series-title":"Spine J","doi-asserted-by":"publisher","first-page":"289S","DOI":"10.1016\/j.spinee.2004.07.021","article-title":"Complications and surgical revision for failed disc arthroplasty","volume":"4","author":"Kostuik","year":"2004"},{"key":"b5-spine09429","series-title":"Orthop Clin North Am","doi-asserted-by":"publisher","first-page":"315","DOI":"10.1016\/j.ocl.2005.02.001","article-title":"Clinical results of Maverick lumbar total disc replacement: two-year prospective follow-up","volume":"36","author":"Le Huec","year":"2005"},{"key":"b6-spine09429","series-title":"Spine","first-page":"1576","article-title":"A prospective, randomized, multicenter Food and Drug Administration investigational device exemption study of lumbar total disc replacement with the CHARITE artificial disc versus lumbar fusion: part II: evaluation of radiographic outcomes and correlation of surgical technique accuracy with clinical outcomes","volume":"30","author":"McAfee","year":"2005"},{"key":"b7-spine09429","series-title":"Spine","doi-asserted-by":"publisher","first-page":"1217","DOI":"10.1097\/01.brs.0000217689.08487.a8","article-title":"Revisability of the CHARITE artificial disc replacement: analysis of 688 patients enrolled in the U.S. IDE study of the CHARITE Artificial Disc","volume":"31","author":"McAfee","year":"2006"},{"key":"b8-spine09429","series-title":"J Neurosurg Spine","doi-asserted-by":"publisher","first-page":"556","DOI":"10.3171\/spi.2006.5.6.556","article-title":"Charit\u00e9 lumbar artificial disc retrieval: use of a lateral minimally invasive technique.
