The correction of fixed angular and curved deformities of the long bones almost invariably requires a solution of continuity.
Osteoclasis has been supplanted by open reduction, which makes it possible to approach these problems by methods of precision.
The method described emphasizes that decisions made at the operating table relative to the level and shape of section to be made for the correction of a given deformity are not reliable.
This is true because it has been graphically demonstrated that there is only one level and section of given shape which will result in the maximum correction of a given deformity.
By this method the possibility of inducing other deformities is avoided.
