Abstract

Rotatory atlantoaxial fixation is a common cause of a spontaneous torticollis in children. The normal rotation of the Atlas More Details on the axis becomes limited or fixed in rotatory atlantoaxial subluxation [1]. The etiology of this condition is not known, but it may be related to increased laxity of the alar and transverse ligaments and of capsular structures secondary to inflammation or trauma. The importance of recognizing atlantoaxial fixation lies in the fact that it may indicate a compromised atlantoaxial complex with the potential to cause neural damage or even death. Radiologic evaluation of the patient with this condition is difficult because of the patient's rotated head position. Before the advent of CT, radiologic diagnosis required careful functional examination with cineradiography [2] [3]. The advantage of CT over cineradiography is the ease of performance and interpretation.
