1 Flat back syndrome. Flat back syndrome. (A) The preoperative middle-column height is mm. (B) The postoperative middle-column height utilizing a commercially available digital mapping program measuring the same endpoints is mm, indicating 7.2 mm of overdistraction. This may or may not create symptoms but the stretching and alteration of soft tissues, especially neural elements, needs to be appreciated—they are not integrated into the programs. The 3 triangular wedges of missing radiographic data on the lower left half of the image represent unanticipated lengthening of soft tissues. PAUL C. McAFEE et al.
