Untreated Anderson Type II Odontoid Fracture with Severe Delayed Atlanto-Axial Dislocation, Lateral Mass Misleading Signs of Fusion, and Posterior Surgical Approach: A Case Report

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...

Posterior Hip Fracture -Dislocation Associated with Ipsilateral Intertrochantric Fracture; a Rare Case Report

Hip dislocation occurs when the femur does not break and the force is transmitted towards the hip joint leading to a posterior dislocation of the femoral head with or without posterior acetabular fracture. We present the case of a 26 year old patient involved in motor vehicle accident. Clinical and imaging (radiography, CT) examination revealed an intertrochanteric fracture associated with ipsi...

Traumatic Posterolateral Atlantoaxial Dislocation with Type II Odontoid Fracture: Case Report

Background context: The combination of atlantoaxial joint dislocation and odontoid process fracture is usually a lethal injury and as a result, reports of survivors are rare. In the last thirty years only fifteen clinical cases have been described. Purpose: We present a case of a 30 year old patient with a traumatic posterolateral atlantoaxial dislocation (type V dislocation based on the Fieldi...
