Background: The shapes of an arc and scoliosis are the some. Therefore, the geometry of an arc can reveal the relationship between the angles within and around a scoliotic spine. Objective: To look for angles which are functions of the geometry of an arc and can also be used for assessment of curve progression in scoliosis. Design: Review of the geometry of an arc and that of scoliosis. Method: English literature on scoliosis (from 1930 to date), searched manually, via Internet and from colleagues, was reviewed. Results: Methods of curve measurement in use presently are functions of the geometry of scoliosis. Three additional methods are proposed for assessment of curve progression in scoliosis. These methods are geometrically related with the previously known ones. Conclusion: All methods of assessment of curve progression in scoliosis are fundamentally the same and interchangeable. There is no reason for preference of one method over another method of curve measurement.
