 Goel et al. reported an experience with 190 cases having os-odontoideum. The management outcome following [[atlantoaxial fixation]] is analyzed. Goel et al. reported an experience with 190 cases having os-odontoideum. The management outcome following [[atlantoaxial fixation]] is analyzed.
  
-During the period January 2000 to September 2018, 190 patients having os-odontoideum were surgically treated. There were 113 males and 77 females and their ages ranged from 2 to 68 years (average 24 years).The patients were divided into three groups depending on the nature of atlantoaxial dislocation (Group 1- mobile and partially or completely reducible atlantoaxial dislocation,​ Group 2- fixed or irreducible atlantoaxial dislocation and Group 3- presence of basilar invagination). Sixty- five patients were in pediatric age group (less than 18 years). All patients underwent atlantoaxial joint manipulation and lateral mass plate and screw fixation. The operation was aimed at segmental atlantoaxial arthrodesis. No transoral or posterior foramen magnum bone decompression was done. Occipital bone was not included in the fixation construct.+During the period January 2000 to September 2018, 190 patients having os-odontoideum were surgically treated.

 On direct bone handling and observation,​ atlantoaxial joint pathological hyperactivity related instability was identified in all patients. Atlantoaxial segmental stabilization resulted in clinical symptomatic and neurological improvement in 100 percent patients. On direct bone handling and observation,​ atlantoaxial joint pathological hyperactivity related instability was identified in all patients.
