Since the syndrome was first described concurrently by Morquio [1] and Brailsford [2] in 1929, radiology has played a vital ro le in the diagnosis of the Morquio-Brailsford syndrome and in the management of complications of the disease. Symptoms of spinal cord compression are common. They are related to dysplasia of the dens with atlantoaxial subluxation and narrowing of the spinal canal [3-5]....

BACKGROUND At present, traumatic atlantoaxial dislocation or C2-3 instability complicating odontoid fractures remains rarely reported. The aim of this study was to further investigate the surgical treatment strategies and curative effects for odontoid fractures combined with instability of adjacent segments. METHODS This is a retrospective study of 12 patients (5 females and 7 males; age, 21-...

Over the past century, steady advances have been made in fixating an unstable atlantoaxial complex. Current options for fixation of the atlantoaxial complex include posterior clamps, posterior wiring techniques, C1-C2 transarticular screw fixation, posterior C1 lateral mass screw with C2 pars or pedicle screw fixation, and anterior transoral C1 lateral mass to C2 vertebral body fixation.
