Long-term results of ventro-dorsal versus ventral instrumentation fusion in the treatment of spondylitis.
This study examines prospectively the randomised, long-term, clinical and radiological results of the treatment of spondylitis patients by ventro-dorsal or ventral spine fusion. Group 1 consisted of 12 patients who (after ventral removal of the focus of infection and autologous bone grafting) were treated by dorsal instrumentation. Group 2 consisted of ten patients who, after similar ventral removal and bone interposition, were stabilised by ventral instrumentation. The patients prospectively underwent clinical and radiological studies. In addition, they were asked to fill in self-assessment questionnaires such as the short-form (SF)-36 health survey, the Oswestry questionnaire, and the visual analog scales (VAS). The postoperative follow-ups were at 6 months, 2 years and 5.4 years. It proved possible to demonstrate clinically that patients with an isolated ventral spondylodesis feel significantly better and experience significantly less pain in the area of spinal fusion than patients with ventro-dorsal fusion 2 and 5.4 years after the operation. Over a number of years a stable fusion can be achieved through either operation. Ventral stabilisation yields more advantages than dorsal instrumentation in the long term. These advantages result in a clinically smoother course after the operation. If, in the individual case, ventral instrumentation is feasible, this method should be used.
