A radiographic method for three-dimensional analysis of spinal configuration.

Current two-dimensional methods for quantifying scoliosis are inadequate. A radiographic method has been developed which determines the three-dimensional location and rotation of each vertebra. Posteroanterior and posterior oblique radiographs of the spine are obtained with the patient standing within a reference frame. Computerized analysis of these radiographs provides a complete quantitative description of spinal configuration. Using this information, scoliosis progression may be more accurately predicted, and therapeutic measures can be more thoroughly analyzed utilizing biomechanical principles.
