Objectives : The os odontoideum is an uncommon abnormality which is due to non fusion of axis and odontoid process that exists as a separate ossicle apart from a hypoplastic dens. Its clinical significance lies in its potential to produce serious neurologic symptoms after cervical Chuna Manipulation Treatment. We experienced a patient diagnosed as os odontoideum which corresponds to absolute contra-indications of chuna manipulation treatment and report it. Methods : The patient was diagnosed as os odontoideum through cervical spine CT and MRI. Results and Conclusion : During cervical physical examination, we encountered L'hermitte's phenomenon from the patient and suspected one of contra-indications of chuna manipulation treatment. We could diagnose the patient as os odontoideum through cervical spine CT, MRI and prevent him from severe sequelae caused by chuna manipulation treatment.
