Pathogenesis of non-traumatic atlanto-axial subluxation (Grisel's syndrome)

Abstract: Non-traumatic atlanto-axial subluxation (AAS) is an uncommon complication of upper neck inflammatory processes and head and neck surgery. It is also known under the eponym of Grisel's syndrome (GS). We present a case report of a 6-year-old boy with GS that resulted from a retropharyngeal abscess. A diagnosis was not made until 2 months after the occurrence of infection. Re-evaluation of repeated CT scans of the neck showed the sequential development of AAS. These findings implied that the pathogenesis of GS is… Show more

“…As proposed by Welinder at al [7], GS starts as a typical torticollis from the spasm of irritated neck muscles, however, in the prevalence of preexisting lax C1-C2 ligaments, this spasm leads to subluxation of the atlas and axis. This theory can in fact explain the prevalence of GS in children and Down syndrome patients.…”

“…Nearly a century later, Pierre Grisel [11] described three patients with pharyngitis and torticollis who also had dislocation of the C1-C2 joint. Ever since, the condition has been called Grisel's syndrome (GS), with numerous case reports showing a strong association between its occurrence and upper respiratory tract infections or surgical interventions in the head and neck region [8,22,26].…”

“…Muito mais frequente em crianças, a fixação rotatória C1/C2 é, na maioria dos casos, precedida por uma IVAS ou afecção inflamatória do pescoço ou cabeça [4][5][6] . Quando ocorre em adultos em geral é devido a traumatismos de alta energia, tais como acidentes automobilísticos.…”
