Atlanto-axial fixation in traumatic Atlanto-axial dislocation with odontoid process fracture

Atlanto-axial fracture-dislocation.

Congenital atlanto-axial dislocation.

Atlanto-axial dislocation IS an uncommon condition. It is usually secondary to trauma, infection (tuberculous and non-tuberculous atlas and axis) and rheumatoid arthritis. Other uncommon causes reported include retropharyngeal abscess, malignant deposits, ankylosing spondylitis (Sorin, et al, 1979). Congenital atlanto-axial dislocation is rare. Wadia (1967) first drew attention to its relative ...

Traumatic atlanto-axial subluxation.

Traumatic atlanto-axial subluxation is a rare injury which may not be revealed on routine radiographs, especially when there is muscle spasm. We report on seven patients with atlanto-axial subluxation as a result of neck injury; only two of them had significant head injuries. Three patients presented with a neurological deficit attributable to the injury, one immediate and two with delayed onse...

Brook’s Wiring for Treatment of an Atlanto-Axial Dislocation and Odontoid Fracture in a Child

Cervical spine injuries are rarely seen in children with an overall incidence of about 1-1.5% [1,2]. In pediatric cervical spine injury, the upper cervical spine is the most common site affected (52% of cases) [2]. The typical injury mechanisms for pediatric cervical spine injuries are hyper flexion movements as in motor vehicle accidents, because of distinct anatomic properties of a child’s bo...

Atlanto-axial fusion with transarticular screw fixation.

We reviewed 161 patients, from four centres in Switzerland, who had undergone posterior fusion of the upper cervical spine with transarticular screw fixation of the atlanto-axial joints. They were followed up for a mean 24.6 months. The vertebral artery and the medulla escaped injury and only 5.9% of the complications were directly related to the screws. The rate of pseudarthrosis was 0.6%.
