Objetive: There are many approaches to the thoracolumbar spine: anterior, lateral, posterior and combined. Each one of them present advantages and disadvantages. The posterior progressive fragmentary corporectomy (PPFC) or transpedicular corporectomy offers the advantage to be made in a single surgical time, allowing in addition to lessen the risks of the other approaches and to obtain a suitable stabilization of the spine. Material and Methods: Analysis of the technique and practice of an apprach in a cadaveric specimen giving importance to the remark of certain details of the technique. Restrospective study between years 2001-2005. Diverse epidemiologic preoperating and postoperative variables were analyzed from data of the of 27 operated patients with this procedure. Results: Localization: 10 at lumbar and 17 at dorsal spine. Etiology: 3 infectious, 10 traumatic and 17 tumoral pathologies. Twenty four patients were stabilized in an unique operation, and three in a second time (given its infectious etiology). Only one patient presented a CSF leak as a complication. No patient presented aggravation of inicial neurological state. All the cases showed good spine stability. Conclusion: The amount of operative exposure achived using this technique is wide and safe. We consider this approach as an option for the treatment of vertebral body pathology.
