Atlanto-axial rotatory fixation is a persistent deformity of the C1–2 vertebral relationship caused by subluxation of the articular surfaces, and can occur after positioning for ENT procedures where the head is rotated – for example to access the ear or posterior triangle of the neck. If promptly recognised, it can usually be managed successfully with conservative methods, without long-lasting sequelae, but delayed or inappropriate management may lead to permanent neck deformity, neurological problems and pain.
Case review.
Two children with atlanto-axial rotatory fixation following ENT surgery; one child was referred early and managed successfully, and one had delayed referral resulting in permanent severe positional deformity.
Atlanto-axial rotatory fixation is easily missed; there are significant clinical and medicolegal implications if it is not promptly recognised. A suggested management algorithm is presented.
