case_images: On examination, the patient had a classic "cock robin" deformity with his head being tilted to the left and chin turning to the right (Fig. 1).
case_images: Pre-operative computed tomography coronal cuts showing unilateral C1-C2 facetal dislocation. There were associated abnormalities consisting of unilateral occiputo-atlantal fusion and C2-C3 fusion.

case_images: CT scan revealed the same findings and the subluxation could be classified as Fielding and Hawkins type 1. CT scan and MRI showed C1-C2 subluxation with kyphotic deformity the apex of which was impinging on the brainstem (Fig. 4).
