Abstract
Material and method We researched consequent 40 adult spinal deformity patients in our institute during January 2012 to January 2013. The mean age of patients was 60.1 years old. The research item was SVA, LL, TK, PT, PI, SS and EGA. We have movie recording from the side of the patients walking. We set markers at the External auditory pore and the Greater trochanter, and de fine the straight line between them as the EG line. We then measure the angle between the horizontal and EG lines. We call the angle “EGA-DARTFISH” if measured (over time) during gait analysis, and “EGA-XP” if measured radiographically. [Fig. 1, 2] We used the StatFlex ver.6.0 the statistical processing. We were calibrated in order to perform more accurate measurement. In this measurement, distortion at the screen edges is negligible.
Highlights
There are many evaluation tools of spinal deformities such as sagittal vertical axis (SVA), lumbar lordosis (LL), thoracic kyphosis (TK), pelvic tilt (PT), pelvic incidence (PI), sacral slope (SS) and so on
no reliable parameters have been defined for measurements of spinal alignment
We were calibrated in order to perform more accurate measurement
