(The amount of radiation is small–less than the radiation in half of one CT scan.) This scan helps identify damaged bones. Nuclear bone scan: a diagnostic procedure in which a radioactive substance is injected into the body to measure activity in the bones.CT scans are more detailed than general X-rays. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. Computed tomography scan (CT scan): a diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce detailed images of the body.Magnetic resonance imaging (MRI): a diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body.2 and 3 associated with atlantoaxial instability were studied. N2 - In this report, the authors describe the case of a 3-year-old child with a traumatic Type III odontoid fracture. Twelve patients with odontoid fracture type II, Figs. It is a mechanically unstable injury, but one which has good prognosis for healing. X-rays: test that uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs on film. T1 - Traumatic Type III odontoid fracture and severe rotatory atlantoaxial subluxation in a 3-year-old child. This odontoid fracture extends into the body of C2, making it a type III dens fracture.If a Type II Odontoid Fracture is suspected, the doctor may order the following diagnostic procedures: The doctor will take a complete medical history and perform a complete physical examination. Key words: odontoid fracture, anterior odontoid screw, traction. In this article, we describe the re alignment of displa ced operated type 3 odontoid with anterior screw fixation with cervical traction. This makes them the most likely to require surgery. Abstract: Odontoid fractures are particularly dangerous variety of cervical injury, due primarily to spinal cord trauma. However, there is a rare subtype of Type III odontoid fractures that is similar in the degree of instability to atlanto-occipital dislocation injuries. Type II fractures are considered the least stable of the odontoid fractures. OBJECTIVE AND IMPORTANCE:Type III odontoid fractures are generally thought of as unstable fractures that can be successfully treated with an external orthosis. In an unstable fracture, the bone is more likely to move out of its normal position and alignment. A stable fracture may “set” and heal itself. In a stable fracture, the bone does not move out of its normal anatomical position and alignment. Some fractures are considered stable, and some are unstable. In a Type III fracture, the bone is broken below the base of the peg. Check MRI prior to Open reduction ACDF then PCF if HNP is large. Type III Open reduction of C2, then C2-3 PSF with C2 pedicle lag screw. In a Type II fracture, the most common type, the peg is broken at its base. Immediate halo vest under image intensification, using the vest to help achieve extension and compression, use for 3 months. Etiology: failure of fusion during childhood or old traumatic process. Posterior Interspinous Ligament Disruption. In a Type I odontoid fracture, just the tip of the bone is broken. Up to 34 of odontoid fractures have additional cervical spine injuries. In an odontoid fracture, that peg of bone is broken. The odontoid process sticks up from the front of C2 and fits into a groove in C1. It is about the size of the tip of a pinky finger. One of the unique features of this joint is a peg of bone called the odontoid process (sometimes called the dens). This is the joint that allows the head to rotate from side to side, bend forward and bend backward. Not recognizing or not treating this injury urgently and aggressively could lead to. The joint between C2 and the vertebra above, C1, has an outstanding range of motion. OBJECTIVE AND IMPORTANCE:Type III odontoid fractures are generally thought of as unstable fractures that can be successfully treated with an external orthosis. The bone involved in odontoid fracture is the second vertebra, C2, high up in the neck. Odontoid = A peg-like part of the second bone in the neckĪ type II odontoid fracture is a break that occurs through a specific part of C2, the second bone in the neck.īones of the spine are called vertebrae. ![]() ![]()
