Cotrel-Dubousset instrumentation for lumbar spine Chordoma: A report of two cases

Two cases of lumbar Chordoma treated surgically are reported. The circumferential excision of the tumour was planned using computed tomography. The resected vertebral body was replaced with a tricortical autologous graft. Posterior simultaneous stabilization of the spinal column was achieved by Cotrel-Dubousset (C-D) instrumentation. The interlocking mode of the system provided an effective stabilization with preservation of the natural sagittal curve and early ambulation.
