A 31-year-old female complained of neck pain and limitation in neck motion. She had a 3 month history of treatment with Halovest at another hospital for a fracture of the odontoid process due to a car accident. The patient complained of persistent pain and limitation in neck motion following the cessation of Halovest. A dynamic radiograph demonstrated instability on C1-2 and she underwent a posterior cervical fusion with wiring. A wound infection developed, and loosening of the wire and lysis of the posterior arch at C1-2 were seen on a follow up plain radiograph 2 months postoperatively. She was transferred to our hospital where she underwent occipitocervical fusion with a double plate after control of the infection. There were rigid fixations of the plate and bone union on a follow up radiograph 24 months postoperatively.
