Irreducible Atlanto-Axial Dislocation in Neglected Odontoid Fracture Treated with Single Stage Anterior Release and Posterior Instrumented Fusion

Irreducible Atlanto-Axial Dislocation in Neglected Odontoid Fracture Treated with Single Stage Anterior Release and Posterior Instrumented Fusion.

It is a well-know fact that type 2 odontoid fractures frequently go into nonunion. If left untreated, patients may develop irreducible atlantoaxial dislocation (AAD). We describe the surgical management of two patients with neglected odontoid fractures and irreducible AAD treated with single stage anterior release followed by posterior instrumented fusion. Both patients presented with history o...

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 deformity secondary to a neglected odontoid fracture: a report of six cases.

We reviewed 6 patients with atlanto-axial (C1-2) deformities secondary to neglected odontoid fractures. All patients (except one with recent injury) were asymptomatic for a long period before development of neck pain or myelopathy, despite obvious subluxation and kyphotic deformities at the C1-2 joint complex. Patients were treated conservatively, except for one who underwent posterior spinal f...

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 ...
