I have a friend who suffers from a unilateral c1 c2 problem; she is in her late 60s, a small boned person; there was a traumatic injury some years back, and gradually this small spot of pain in her upper neck settled in and increased. She has no other neurological symptoms. The radiography to date shows osteophytes in the c1/c2 joint, and I think a swollen capsule. vertebral artery trajectory is normal. It was eventually noted there is a small sliver of bone near the site. I think posterior fusion with rods and screws is the best total treatment, but, if she fears to undergo that (the risks), could that sliver BE the source of her sharp, localized pain and COULD it be removed in a less invasive manner, perhaps solving the pain issue, do you think?
