The authors describe the surgical method and results of nonexpansive one-piece multivel laminoplasty of the whole lumbar spine, for microsurgical resection of extensive spinal tumors. This technique allows a very confortable approach to the dura and intradural content, as well as a perfect replacement of the posterior spinal arch with supporting elements and an optimal reconstruction of the spinal anatomy. A nonexpansive whole lumbar one-piece laminoplasty was performed for resection of extensive multilevel lumbar tumors. The authors report an illustrative case of a patient who initially presented with a three-year history of numbness on both legs and progressive difficulty in walking. Two months before admission, he complained of bilateral sciatica and rectourinary dysfunction. A spinal magnetic resonance imaging (MRI) documented an intradural tumor extending from L2 to S1. The patient underwent a nonexpansive whole lumbar one-piece laminoplasty and microsurgical removal of the intradural lesion. The postoperative course was uneventful, the sensory disturbances and bilater sciatica early recovered while rectourinary disturbance gradually improved up to a complete resolution at one year follow-up. The authors believe that multilevel laminoplasty rather than laminectomy is the technique of choice as a posterior procedure for extensive lumbar spinal tumors. With this technique, it is possible to obtain a very confortable approach to the dura and intradural content, as well as a perfect replacement of the posterior spinal arch with supporting elements and an optimal reconstruction of the normal spine. Moreover, this method prevents postoperative instability and deformity and avoids the so called post-laminectomy epidural membrane.
