![]() ![]() Are the pre-vertebral soft tissues normal (p. Are the three main contour lines/arcs normal (p. Are the other vertebrae (C3–C7) intact (p. ![]() If you are struggling to see down to the level of C7/T1, a fourth swimmer’s view can be requested. Are the posterior arches of C1 and C2 intact?Ĩ. Typically there are three standard views provided when a cervical spine X-ray is performed, these include a lateral, antero-posterior (AP) and odontoid/open-mouth view. As technology advances, computed tomography (CT) has replaced this projection, yet there remain many institutions (especially in rural areas) where CT is not readily available. Cervical spine lateral view is a lateral projection of the cervical spine. Is Harris’ ring 7 normal? A break in either the anterior or posterior margin of the ring indicates the high probability of a fracture of the Peg/body of C2 (p. Citation, DOI, disclosures and article data. Is the line of the posterior cortex of the Peg continuous with the posterior cortex of the body of C2? Any displacement or break indicates a Peg fracture.Ħ. A lateral view in isolation will only detect 75 of c-spine injuries. This combination allows for good visualisation of the entire cervical spine. Is the line of the anterior cortex of the Peg continuous with the anterior cortex of the body of C2? Any displacement implies a Peg fracture or fracture of C2 body.ĥ. Injuries are most often missed because of poor radiographic technique and/or inaccurate film interpretation 1, 2, 4 6.Most errors are avoidable 5.Missed C-spine abnormalities occur most commonly at the top or at the bottom of the C-spine 1, 2. Where plain radiography is indicated, three films are taken of the cervical spine: lateral, anteroposterior (AP) and open mouth (peg) views. Tables 4-3, 4-4, 4-5 and 4-6 provide a detailed checklist for a pathological assessment for the AP open-mouth and AP lower cervical views. Is the anterior cortex of the odontoid peg (the Peg) closely apposed to the “coffee bean”?Ĥ. Christopher Kent 1 provides a thorough checklist for assessing lateral cervical radiographs in Tables 4-1 and 4-2. Have I identified the anterior arch of the C1 vertebra (the “coffee bean”)?ģ. Materials and Methods: An anthropomorphic phantom was positioned AP erect against a digital radiography (DR) detector with 30 thermoluminescent dosimeters (TLDs). Is the radiograph technically adequate? Ensure that the C1–C2 articulation and the superior surface of the T1 vertebra are clearly seen.Ģ. ![]()
