Some institutions will advise the Judet views are done as a full two view oblique pelvis (see figure 1 and 2). In: Moore EE, Mattox KL, Feliciano DV, editors. The Judet view is a two-part view of the acetabulum, the collimation of the Judet views is departmentally dependent. Initial assessment of the trauma patient. The findings of this study suggest that supine oblique views may be a useful part of the standard evaluation of the acutely injured cervical spine however, they may not reliably portray clinically important anteroposterior displacements.Ĭollicott PE. Although supine oblique views detected many subluxations, they produced numerous false-negative and false-positive results. Significant differences in diagnostic accuracy were detected between the horizontal lateral and the supine oblique views to detect malalignment. The data for each projection were compared using alternative free-response operator characteristic and free-response forced-error methodologies. Blinded to experimental conditions, six observers evaluated every intervertebral level on each lateral and oblique image in isolation. Since each intervertebral level (C2-T1) was individually evaluated, the study sample consisted of 150 intervertebral segments. In the remaining 22 sets, there were 43 intervertebral segments with an abnormal anteroposterior displacement. Twenty-five sets of radiographs were obtained, of which three were normal. A normally aligned dry cervicothoracic vertebral specimen and the same specimen with varying degrees of subluxation at one or more levels were radiographed in anteroposterior, lateral, and 45° oblique projections, in a simulated supine position.

Neck injury caused by a sudden jerking of the head is commonly called whiplash.To determine whether supine 45° oblique radiographs of the cervical spine can accurately detect and quantify anteroposterior intervertebral plane displacements, an observer performance study was performed. If your neck is dislocated or fractured, your spinal cord may also be damaged. This is especially true with falls, car accidents, and sports, where the muscles and ligaments of the neck are forced to move outside their normal range. The neck is particularly vulnerable to injury. Your doctor may request a neck X-ray if you have a neck injury or pain, or persistent numbness, pain, or weakness in your arms.
