It is the usual case of extruded disc L4-5 with right downward migration. Here also an example for using drilling to attack the compressed area in a circumferential fashion, even in hemiflavotomy, to avoid insertion of the Smith-Kerrison
rongeur at the maximally compressed area. The flavum is gripped and pulled out of the area to decompress the area before attacking it. After exposing the root, it is save to explore the migrating disc and remove it. In such way the surgical trauma to the compressed structures reach nearly zero. The weakness immediately disappear after surgery as in this case.
