This is the case of a 4 year old male child who sustained a moderate trauma (falling off a bed landing head first) with left lateral head tilt and right lateral rotation the "cock robin" position that is typical or atlantoaxial rotary fixation.
Results: Two weeks following the spinal adjustment, the patient returned to the clinic reporting that complete resolution had occurred and no clinical signs or symptoms were present to substantiate further radiographic study.
From the conclusion: "Any child presenting with a recent upper respiratory infection, sore throat, otitis media or minor trauma with torticollis is a candidate for consideration of atlanto-axial rotary fixation."
