The importance of early and efficient treatment of patients with scoliosis, arises from the extreme uncertainty of their future progress. It is known that in some patients the condition may become spontaneously arrested in an early stage; in other cases, the disease may increase, and may not only produce extreme deformity but seriously impair the general health. The aim of treatment should be to prevent the progress of the deformity, to correct, if possible, the existing deformity and to maintain the correction until all danger of relapse is past. This usually means until maturity is reached.
The correction of spinal curvature requires much attention to detail, and individual adaption of the various procedures, varying largely with the location and degree and, to a lesser extent, with the etiology of the deformity. For this reason it was thought desirable to study a series of cases to determine, as accurately as possible,
