No one biased in his belief should attempt the study of either the causes or treatment of scoliosis. We must approach the subject with an open mind. Each case is a problem in itself.
The treatment of structural lateral curvature is now advancing apace with our knowledge of other medical and surgical problems. This has been made possible by the investigations of Drs. Bradford, Lovett, Feiss and Forbes, and of late the study of the subject has been stimulated anew by the announcement of Dr. Abbott of Portland. Drs. Bradford and Lovett1 studied the motions of the normal human spine in its various positions. They found there was no sidebending without rotation and no rotation without sidebending. They also found these motions were more free in flexion.
Lovett2 experimented with the column of bodies and disks without their posterior segments and found it obeyed the laws of physics
