What is a Type 3 dens fracture?

A type III odontoid fracture is a fracture through the body of the C2 vertebrae and may involve a variable portion of the C1 and C2 facets. Type III odontoid fractures occur secondary to hyperextension or hyperflexion of the cervical spine in a similar manner to type II odontoid fractures.

What is a type 2 dens fracture?

A type II odontoid fracture is a break that occurs through a specific part of C2, the second bone in the neck. Bones of the spine are called vertebrae. The bone involved in odontoid fracture is the second vertebra, C2, high up in the neck.

What is a fracture of the dens?

A fracture of the odontoid bone (also called the dens), is an upward extension of C2 cervical vertebrae (i.e., axis) up into the C1 cervical vertebrae (i.e., atlas) and is held in place partially by the alar, apical and transverse ligaments. There are three types of dens fractures with type II being the most common.

What is the dens of C1?

C1 and C2 vertebrae. The C1 vertebra, also called atlas, is shaped like a ring. The C2 vertebra has an upward-facing long bony process called the dens. The dens forms a joint with the C1 vertebra and facilitates its turning motions, thereby allowing the head to turn in different directions. See Cervical Vertebrae.

Is the dens on C1 or C2?

C1 and C2 vertebrae. The C1 vertebra, also called atlas, is shaped like a ring. The C2 vertebra has an upward-facing long bony process called the dens. The dens forms a joint with the C1 vertebra and facilitates its turning motions, thereby allowing the head to turn in different directions.

What are the dens?

The odontoid process, also known as the dens, is an upward projectile of bone that arises from the front part of the center of the axis vertebra. (The axis is the 2nd highest spinal bone.) The atlas is the first bone of your neck; it sits on top of the axis.

What is a Galeazzi fracture?

A Galeazzi fracture is a fracture of the middle to distal third of the radius associated with dislocation or subluxation of the distal radioulnar joint (DRUJ). Advances in radiography and fracture research have helped define, classify, and guide operative management.

What vertebra contains dens?

The second cervical vertebra, or axis, supports the dens, or odontoid process, which projects rostrally from the body, serving as a pivotal restraint against horizontal displacement of the atlas.
