Clinical course of the patients in the study

	Patient 1	Patient 2	Patient 3
Age (years)	53	31	28
Traumatic event	Motor vehicle collision	Motor vehicle collision	Motor vehicle collision
Physical examination	Severe neck pain, neurologically intact	Severe neck pain, neurologically intact	Multiple injuries including brain contusion, facial bone fracture but neurologically intact
Imaging	C2 body fracture with anterior displacement, extending to pars interarticularis bilaterally	C1 vertebra anterior and posterior arch fracture with avulsion of transverse ligament tubercle	C2 body fracture extending to pars interarticularis bilaterally + congenital fusion of atlantooccipital joint
Postoperative course	Uneventful, discharged day 3 postoperative	Uneventful, discharge was delayed until day 15 due to concurrent femur fracture slowing mobilization	Long hospital stay due to brain injury, but cervical spine injury was managed in a similar matter to the other two cases once the patient regained full mental capacity 17 days after admission and medical stabilization
CT evaluation at 6 months	Fracture fully united	Fractures fully united	Fractures fully united
Last follow-up	At 2 years, mild limitation in neck rotation but no loss of flexion/extension and no functional deficit	At 18 months, full range of motion regained except for mild loss of rotation possibly due to concurrent C7 fracture treated with a fusion	At 12 months, limitation was only in flexion-extension, but that could be due to congenital atlanto-occipital fusion
