 Pediatric atlantoaxial rotatory subluxation is rare. We report a case of pediatric atlantoaxial rotatory subluxation and aplasia of posterior arch of the atlas. The patient was a 4-year-old girl with severe neck pain,who had complained of neck pain since she was 3-years-old. Examination revealed no neurological deficits,but range of motion testing revealed limitations in flexion and left rotation,and she exhibited torticollis. Union of the C2/3 lamina was observed on radiographs,and CT showed aplasia of the right posterior arch of the atlas and aplasia of the atlantoaxial joint. The evidence of aplasia seemed to be related to the instability of the atlantoaxial joint. Unilateral bone grafting was performed for the atrantoaxial joint (Brooks method). The neck pain resolved after surgery. Bone union was observed on radiographs 9 months after surgery. Unilateral bone grafting was successful in treating pediatric atlantoaxial rotatory subluxation and aplasia of posterior arch of the atlas.
