The Effect of Scoliosis Fusion on Spinal Motion: A Comparison of Fused and Nonfused Patients With Idiopathic Scoliosis

Abstract

Diminished spinal motion can be measured in patients who have had spinal fusions. Although stiffness in the operated curves should be expected, compensatory hypermobility in the unfused segments does not occur, resulting in a net loss of flexibility compared to controls.
