(2000) , there is specialization in the
lumbo- sacral vertebrae and spinal cord in birds, which can be assumed for animals moving on ground.
Chest radiographs, abdominal and
lumbo- sacral spines radiographs were chosen because of the proximity of these body parts to radio- sensitive organs in the body.
[9, 4, 2] The interrelationship between proximal (lower back) and distal body segments (knee) has been confirmed by Crewe et al., [3] who found an association between a more extended front knee during the front foot contact phase and
lumbo- pelvic shear forces.
