Standardized traction versus side-bending radiographs in adolescent idiopathic scoliosis: a preliminary study.

The aim of this study was to develop a new type of preoperative flexibility test for adolescent idiopathic scoliosis. The objective was to develop a test that was standardized and allow for the measurement of in-vivo forces required for curve correction. It was undertaken to compare the results of this new test with side-bending radiographs.
