The Importance of the Fractional Curve

  • Michael Y. Wang


The last decade has witnessed the proliferation of techniques and technologies for minimally invasive spinal surgery (MIS). Many of these methods have now been effectively applied to treat spinal deformities, with the end result being that modern MIS surgeons have had to develop an understanding of traditional deformity principles. It cannot be overstated that deformity surgeons have spent the past 70 years developing an understanding of the principal tenets and goals of surgical intervention. This level of understanding, while continually in evolution, has been the result of tireless research, with the primary goal of improving patient outcomes. Needless to say, the application of MIS techniques should be applied with these principles foremost in mind. Examples of these tenets would include achieving a successful arthrodesis, respect for neural tissues, not stopping a fusion at the apex of a curve, and restoration/maintenance of coronal and sagittal balance.
