The Pang and Li class was then compared with the radiologist's report, which was graded abnormal, diagnosis of rotatory subluxation or fixation, or non-diagnostic. Medical records were reviewed and the clinical course was compared among the five subtypes.RESULTS We reviewed 47 CT scans in 35 patients, and the majority were performed without sedation. The average age was 7.7 years(4-14 years old) and associated conditions included minor trauma(20%), surgical procedures around the head and neck(29%), and Grisels syndrome(20%). Twenty-six percent of our studies fell within the pathologic spectrum(5% type 1 or rotatory fixation, 21% types 2 and 3 or rotatory subluxation), while 45% were classified as muscular torticollis(45%) and 28% fell within the diagnostic grey zone. Seven radiologists interpreted these studies, and their interpretation was discordant in 45% of cases. Clinical resolution occurred in 27 of 29 cases for which follow-up was available. One of two patients with fixed rotatory subluxation required a C1-C2 arthrodesis.CONCLUSION The Pang and Li classification characterizes a spectrum of abnormalities in rotation to facilitate communication, although the indications for dynamic CT scan should be further defined.展开更多
