Abstract

A method was developed for the 3-D measurement of the skeletal alignment of both lower extremities under weight-bearing conditions. The method is based on the use of a positioning and calibration frame (Questor Precision Radiograph), a standardized patient positioning protocol and precision radiography. The bony alignment is represented by a cahbrated stick- figure diagram in frontal, lateral and vertical projections. It is supplemented by a list of angular and linear measurements of importance for planning corrective orthopaedic surgery and for evaluating their results.
