Selective Fusion

1. Scoliosis can involve a single curve, however, double or triple curves may be observed. The traditional operative treatment for scoliosis is posterior instrumented fusion. This involves achieving a bony union in the operative field, therefore stopping the motion in the operated vertebra.

   Selective fusion is a method that preserves motion segments. In selective fusion, only one curve is operated in a patient with double or triple curves, and the other curves are spontaneously corrected. This is usually done by operating the thoracic spine and correcting the lumbar spine spontaneously allowing ­for preservation of motion.

   Selective fusion is not suitable for all types and magnitudes of scoliotic curves. Several criteria are applied to evaluate the suitability of the curves for selective fusion.­
