Special Views of the C and T-Spine
| Question | Answer |
|---|---|
| What X-Ray Allows imaging of the Dens when the patient cannot open their mouth? | AP Dens (Fuchs) |
| When positioning the patient for a Fuchs X-Ray, You should extend chin until the______ is near perpendicular to IR | Mentomeatal line (MML) |
| The CR enters at the _________ when performing a AP Dens (Fuchs)? | MSP, just distal to chin tip |
| What method employs a chewing motion that is known as "Wagging Jaw" | Ottonello Method |
| Which position shows the LEFT Intervertebral Foramina Farther away from the board? | RPO |
| Which position shows the RIGHT Intervertebral Foramina Farther away from the board? | LPO |
| Which position shows the LEFT Intervertebral Foramina CLOSER to the board? | LAO |
| Which position shows the RIGHT Intervertebral Foramina CLOSER to the board? | RAO |
| Hyperextension | Patient relax head as far back as possible |
| Hyperflexion | Patient put chin as close to chest as possible |
| Place the Marker on the _______ side when patient is in LPO Position | Right |
| Place the Marker on the _______ side when patient is in RPO Position | Left |
| What X-Ray would we perform to show the degree of anterior/posterior movement of the Head/Neck | Lateral C-Spine; Hyperflexion and Hyperextension |
| Do not attempt a Lateral C-Spine; Hyperflexion and Hyperextension X-Ray if the patient has/suspected to have a? | Fracture |
| What X-Ray is best to visualize C7, T1 and/or T2 on lateral views? | Lateral Cervicothoracic (Swimmer's) |
| Lateral Cervicothoracic (Swimmer's) Patient Position | • Extend arm closer to IR above head, and rotate humeral head anteriorly • If upright, flex elbow, and rest forearm on head • Depress shoulder farther from IR |
| Angle the CR 3 to 5 degrees caudad for a Lateral Cervicothoracic (Swimmer's) only if- | If the patients shoulder cannot be depressed |
| Arm closer to the board goes | Up |
| Arm farther from the board goes | Down |
| Lateral Cervicothoracic (Swimmer's) CR Placement | Perpendicular to C7-T1 interspace if shoulder away from IR is depressed |
