For severe and rigid adult idiopathic scoliosis, does an optimal extent of posterior intervertebral release exist? A finite element analysis

A selective, 4-level PIVR strategy provides superior deformity correction and a more favorable stress environment than a more extensive release. These findings challenge the "more is better" paradigm, providing a biomechanical rationale for an "optimal" rather than "maximal" release approach in severe rigid AdIS.

Abstract

A selective, 4-level PIVR strategy provides superior deformity correction and a more favorable stress environment than a more extensive release. These findings challenge the "more is better" paradigm, providing a biomechanical rationale for an "optimal" rather than "maximal" release approach in severe rigid AdIS.
