Minimally invasive extracavitary transpedicular corpectomy for the management of spinal tumors

Management of spinal metastasis is a large and challenging clinical problem. For metastatic epidural spinal cord compression, a prospective, randomized, controlled trial showed the utility of circumferential surgical decompression followed by adjuvant radiotherapy. In the setting of those data, surgical techniques evolved from decompressive laminectomy only to anterior corpectomy to posterior-only transpedicular corpectomy. The transpedicular approach has recently been modernized with minimally invasive and mini-open techniques. This article presents the relevant clinical background on spinal metastasis, reviews the surgical technique for minimally invasive transpedicular corpectomy, and finally reviews relevant results in the literature.
