  • Title: Dorsal spondylodesis of unstable thoracolumbar fractures by a far-lateral approach to the disc.
    Author: Rieger A, Rainov NG, Sanchin L, Burkert W.
    Journal: Minim Invasive Neurosurg; 1997 Dec; 40(4):130-3. PubMed ID: 9477401.
    Abstract:
    This paper describes a modified and less traumatic approach to the thoracolumbar spine and compares it with standard techniques for instrumented spinal fusion. Ten patients with unstable fractures of the thoracolumbar spine were included in the open prospective investigation, and were treated by a surgical technique consisting of a dorsolateral approach to the injured segment, filling the disk space and the fractured vertebra with autologous bone, and transpedicular fixation with an AO internal fixator. All patients were followed for 6 to 12 months after surgery by clinical tests and spinal X-rays. Excellent short-term and long-term results were obtained. A stable bony fusion was achieved in all cases, and a minimal mean decrease of 2 degrees in the kyphosis angle was found at late follow-up. No major complications related to the procedure were encountered, and no worsening of neurological deficits occurred after surgery. In conclusion, the far-lateral approach to the thoracolumbar spine yields results which are equivalent or better than those of standard techniques. Major advantages of our procedure, as evaluated in this rather small group of patients, are selective immobilization of the injured segment without involvement of functionally intact spinal levels, no manipulations within the spinal canal boundaries, and relatively limited exposure of the spine.
