From: Changes in L4/5 Intervertebral Foramen Bony Morphology with Age
The intervertebral foramen morphology of different age groups in the right inside slice and exploded view of “35”. (A) morphology of intervertebral foramen in a young subject. (B) morphology of intervertebral foramen in a middle-aged subject. (C) morphology of intervertebral foramen in an old subject. (D) IGES of the divided boundary in the right sagittal inside slice. The distance of “35/36/37/38” is significantly different in different age groups. O is the center of nerve root. (E) 35 in the right inside slice was divided into a in the head-foot direction and b in the ventro-dorsal direction. O is the center of nerve root.
