$odontoid fracture type 1$

It is likely that this mass was a papillary carcinoma of the thyroid. It enhances heterogeneously, and displays flecks of calcification within the mass itself. In our patient, this displaced type III odontoid process fracture was anatomically reduced and then immobilized with a halo vest.Īlso note the large, incidental thyroid goiter. The amount of cancellous bone contact is greater compared to type II fractures. This is in contrast to type II fractures which can be managed conservatively. Their tendency for non-union is due to the limited amount of cancellous bone contact area between the peg and the cervical body. Type II fractures are unstable and non union rates without surgical management is up to 85%. Odontoid peg fractures (OF) are the most common cervical spine fracture in the elderly. Type I fractures can be managed conservatively with a hard collar for 6-8 weeks in duration. The grading of the fracture dictates management. this form of dens fracture is rare - oblique avulsion frx of tip of dens caused by an avulsion of alar ligament - type I frx is avulsion of alar lig off one.

Type III fracture - extension through vertebral body of axis Most dens fractures are caused by motor vehicle accidents and falls About 1/3 of C-spine injuries occur at C2 and about at C6-C7 As expected, most fatal.

Type II fracture - fracture through base of dens - most common odontoid fracture.

$odontoid fracture type 1$

Type I fracture - fracture through tip of dens - 1% of odontoid fractures. Type II: fracture through the base of the dens, at the junction of the odontoid base and the body of C2.

Odontoid fractures can be classified into three different categories 1. Another classification system is the Roy-Camille classification, which aids more in the management of odontoid fractures. Fractures of the odontoid process are common and make up almost one fifth of all cervical fractures 2. The Anderson and D'Alonzo classification is the most commonly used classification of fractures of the odontoid process of C2. The odontoid process is a portion of the axis which arises from the upper surface of the C2 vertebrae. This view may identify spreading or widening of the lateral masses or asymmetry of the separation of the odontoid from the lateral masses, which, in an appropriately centered radiograph, may be.
