I go to get a flexion/extension xray 1 hour before I see the neuro on Aug7 in HLFX and if c2 and c3 are stable I don't want surgery.......does this make sense and if they aren't then I need surgery?

they mention 5mm Anterolisthesis,

Plain films show mild (approximately 5mm) anterolisthesis L4 on L5 with no obvious spondylolysis. Disc height is well maintained.....found this on the internetbut don't know if this is any good.

thanks Lee
