One of the goals of deformity surgery in the spine is to minimize the length of a fusion to preserve best possible motion of non-affected spine segments. A number of factors can contribute to premature recurrence of deformity and failure of motion segments below a fusion. In this University of Washington program, learn how anticipation of spinal balance and adherence to surgical principles can minimize risk for early breakdown of motion segments below a fusion.
