Radical resection of vertebral body tumours. A surgical technique used in ten cases

Abstract

An operation for radical resection of a tumour of the vertebral body and part of the neural arch is described. The approach is posterior and from both sides of the spine. The posterior approach is used to remove the healthy part of the neural arch, mobilise the dura, divide involved nerve roots and carry out the posterolateral parts of the spinal osteotomies or disc divisions. On one side, usually the right, the sides of the vertebral body or bodies are freed and the osteotomies or disc divisions are extended. Then from the other side, a posterolateral thoracotomy or lumbotomy allows completion of the dissection with radical resection by rolling the specimen away from the dura. Ten operations are reported in which up to three and a half vertebrae were resected. Spinal reconstruction was by internal fixation and grafting preferably with vascularised bone. The results were satisfactory after follow-up for as long as eight years.
