Abstract Background: To describe and measure the occipital-cervical distance by a novel method utilizing the occiput-C4 distance (OC4D) in normal subjects that can be used to guide the restoration of vertical dislocation of the occipitocervical region in patients with basilar invagination and to perform standardized testing of occipitocervical constructs.Methods: Neutral, flexion, and extension lateral cervical spine radiographs of 150 asymptomatic subjects (73 males and 77 females) judged to be normal were analyzed. The mean age was 48.0±8.4 years old (range 20–69 years; 48.4±10.2 years old for males and 47.6±6.4 years old for females). Analysis consisted of measurement of the OC4D. The OC4D was defined as the shortest distance from the center of the C4 vertebral body to the McGregor’s line. Two spine surgeons measured the OC4D thrice in the normal population and obtained the average values. Height, weight, and body mass index (BMI) of each subject was recorded and analyze its correlation with OC4D.Results: The values of OC4D on neutral, flexion, and extension lateral cervical spine radiographs were 69.0±6.9 mm, 68.9±6.8 mm and 68.1±6.9 mm, respectively. There was no significantly different from the values measured in neutral、flexion and extension (P> 0.05). But the OC4D of males were higher than females in neutral, flexion, and extension (P < 0.001 for all). There was a positive correlation between OC4D and height and weight in neutral、flexion and extension (P <0.001 for all). The correlation between O-C4D and BMI was weak, and no significant in neutral, flexion, and extension (P > 0.05). The ICC values of inter- and intra-observer agreements for the radiographic parameter in all of the cervical positions were more than 0.93.Conclusions: OC4D, a new measurement method for occipital-cervical distance that is not affected by the change in neutral, flexion, and extension positions, should be a valuable parameter and intra-operative tool to guide the vertical restoration during OCF for patients with altered occiput-cervical anatomy.

This chapter, found in the back pain section of the book, provides a succinct synopsis of a key study examining the use of cervical spine imaging in blunt trauma patients. This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. The study presents a set of five diagnostic criteria that approach 100% sensitivity for identifying clinically important cervical spine injuries and could eliminate one-eighth of all cervical spine radiographs ordered for these patients. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.

Abstract The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Fifth Edition, defines a motion segment as “two adjacent vertebrae, the intervertebral disk, the apophyseal or facet joints, and ligamentous structures between the vertebrae.” The range of motion from segment to segment varies, and loss of motion segment integrity is defined as “an anteroposterior motion of one vertebra over another that is greater than 3.5 mm in the cervical spine, greater than 2.5 mm in the thoracic spine, and greater than 4.5 mm in the lumbar spine.” Multiple etiologies are associated with increased motion in the cervical spine; some are physiologic or compensatory and others are pathologic. The standard radiographic evaluation of instability and ligamentous injury in the cervical spine consists of lateral flexion and extension x-ray views, but no single pattern of injury is identified in whiplash injuries. Fluoroscopy or cineradiographic techniques may be more sensitive than other methods for evaluating subtle abnormal motion in the cervical spine. The increased motion thus detected then must be evaluated to determine whether it represents normal physiologic motion, normal compensatory motion, motion related to underlying degenerative disk and/or facet disease, or increased motion related to ligamentous injury. Imaging studies should be performed and interpreted as instructed in the AMA Guides.

Acute cervical facet fractures are increasingly being detected due to the use of cervical spine CT imaging in the initial assessment of trauma patients. For displaced cervical facet fractures with dislocations and subluxations, early surgery can decompress the spinal cord and stabilize the spine. For patients with non-displaced cervical facet fractures, the challenge in managing these patients is the determination of spinal stability. Although many of the patients with non-displaced cervical facet fractures can be managed with a cervical collar, the imaging needs to be analyzed carefully since certain fracture patterns may be better managed with early surgical stabilization.
