However, it is also known to be associated with considerable surgery-related trauma. The purpose of this study was to show that lumbar corpectomy and anterior reconstruction can be performed via a minimally invasive retroperitoneal approach (MIRA) and therefore the surgical approach\u2014related trauma can be reduced.<\/jats:p>\n<jats:p content-type=\"fine-print\">The authors studied retrospectively the hospital records and radiological studies obtained in five patients (mean age 67.4 years, range 59\u201376 years) who underwent lumbar corpectomy and spinal fusion via an MIRA followed by posterior fixation. Four patients presented with osteoporotic compression fractures at L-2 and L-3, and one patient presented with metastatic disease in L-4 from prostate cancer. Neurological deficits due to cauda equina compression were demonstrated in all patients.<\/jats:p>\n<jats:p content-type=\"fine-print\">The MIRA provided excellent exposure to facilitate complete decompression and anterior reconstruction in all patients, as verified on follow-up radiographic studies. All patients improved clinically. A 1-year follow-up record is available for four patients and a 6-month follow-up record for the fifth patient; continuing clinical improvement has been observed in all. Radiography demonstrated anatomically correct reconstruction in all patients, as well as a solid fusion or a stable compound union in the four patients for whom 1-year follow-up records were available.<\/jats:p>\n<jats:p content-type=\"fine-print\">The MIRA allows the surgeon to perform anterior lumbar spine surgery via a less invasive approach. The efficacy and safety of this technique and its potential to reduce perioperative morbidity compared with conventional retroperitoneal lumbar spine surgery should be further investigated in a larger series.<\/jats:p>","DOI":"10.3171\/spi.2000.93.1.0161","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T15:48:14Z","timestamp":1241711294000},"page":"161-167","source":"Crossref","is-referenced-by-count":11,"title":["Minimally invasive retroperitoneal approach for lumbar corpectomy and anterior reconstruction"],"prefix":"10.3171","volume":"93","author":[{"given":"Manfred","family":"M\u00fchlbauer","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wolfgang","family":"Pfisterer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard","family":"Eyb","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Engelbert","family":"Knosp","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Spine","doi-asserted-by":"publisher","first-page":"2227","DOI":"10.1097\/00007632-199311000-00014","article-title":"Vascular injury in anterior lumbar surgery.","volume":"18","author":"Baker","year":"1993"},{"key":"b2","series-title":"Clin Orthop","first-page":"57","article-title":"Surgical techniques of anterior decompression and fusion for spinal cord injuries.","volume":"154","author":"Bohlman","year":"1981"},{"key":"b3","series-title":"Surgery of the Spine.","first-page":"1115","article-title":"Surgical management of injuries to the thoracic and lumbosacral spine","volume":"2","author":"Bolesta","year":"1992"},{"key":"b4","series-title":"Clin Orthop","first-page":"65","article-title":"Spinal instability as defined by the three-column spine concept in acute spinal trauma.","volume":"189","author":"Denis","year":"1984"},{"key":"b5","series-title":"Eur Spine J","doi-asserted-by":"publisher","first-page":"210","DOI":"10.1007\/BF00395518","article-title":"New possibilities in L2\u2013L5 lumbar arthrodesis using a lateral retroperitoneal approach assisted by laparoscopy: preliminary results.","volume":"5","author":"de Peretti","year":"1996"},{"key":"b6","series-title":"Spine","doi-asserted-by":"publisher","first-page":"1592","DOI":"10.1097\/00007632-199507150-00007","article-title":"The surgical and medical perioperative complications of anterior spinal fusion surgery in the thoracic and lumbar spine in adults.
