cervical spine posit

cervical spine position

QuestionAnswer
what are the basic cervical spine views ap open mouth,ap axial,obliques,lateral,lateral horizonal beam,swimmer's lateral
ap open mouth is also know as what C1 and C2 cervical spine
lateral horizontal beam is use for what the trauma patient
pathologies of ap open mouth is fx involving C1 & C2,demonstrates odontoid & Jefferson fx
what is the patient position for ap open mouth erect or supine with arms by side
A line from lower margin of upper incisors to the base of the skull(mastoid tips) should be perpendicular/parallel to the table/or IR.ap open mouth perpendicular
what is the CR for AP open mouth cr is perpendicular to IR,directed to the center of the mouth
ap open mouth:what should you instruct your patient to do. instruct pt to open mouth that only the lower jaw moves. also to keep the tongue in the lower jaw
why is it important that the pt keep the tongue in the lower jaw. it helps in preventing superimposition of vertebrae by mandible.
how much of a angle is the ap axial 15 to 20 cephalad
what is the CR of ap axial angle 15 to 20 cephalad,to enter to the level of the lower margin of the thyroid cartilage to pass through C4
what does cephalad angulation helps(ap axial) cephalad angulation directs the beam b/w the overlapping cervical vertebral bodies to better demonstrate the intervertebral disk spaces.
when should you angle the tube 15 cephalad on a AP Axial projection angle the tube 15 degrees when the pt is supine or if there is less lordotic curvature
when should you angle the tube 20 cephalad on a AP Axial projection angle the tube 20 degrees when the pt is prone or if there is more lordotic curvature.
what is the pathology on a AP Axial projection. demonstrates the clay shoveler's fx,commpression fx & herniated nucleus pulposus(HNP).involving mid & lower cervical spine C3 to C4.
what are the pathology for a anterior & posterior oblique position stenosis involving the intervertebrae foramen is demonstrated.
why should both anterior & posterior views needed for comparison purposes
what is the preferred position for anterior & posterior oblique position erect position if perferred
what is the CR for a anterior oblique position 15 degrees caudad to C4-level of upper margin thyroid cartilage
what is the CR for a posterior oblique position 15 degrees cephalad to C4-level of lower margin thyroid cartilage
how does turning the head on a anterior & posterior oblique position helps helps in preventing superimposition of vertebrae by mandible.
what is the pathology for a lateral position spondylosis and osteoarthritis are demonstrated
what is the CR for a lateral position CR perpendicular to IR, directed horizontally to C4-level of upper margin of thyroid cartilage
why do we use a 72 inch sid for a lateral position compensates for increased OID & provides for less magnification.
why do we extend the chin on a lateral position to prevent superimposition of the mandible on upper vertebrae
what is a lateral position,horizontal beam used for the trauma patient
what are the pathology for a lateral position,horizontal beam clay shoveler's fx,compression fx,hangmans fx,odontoid fx,teardrop burst fx,subluxation
what is the CR for a lateral position,horizontal beam CR perpendicular to IR,directed horizontally to C4-level of uuper margin of thyroid cartilage
why do we use a 72 inch sid for the lateral position,horizontal beam longer sid results in less magnification with increase image sharpness
what is the other name for the cervicothoracic (swimmmer's)lateral position Twining method for C4-T3 Region
what are the pathologies for the swimmer's lateral position inferior cervical spine,superior thoracic spine,& various fx subluxation are demonstrated
what is the sid for the swimmer lateral position 72 inches
what is the CR for the swimmer's lateral position CR perpendicular to IR CR centered to T1
why is a slight caudad angulation needed for the swimmer's lateral position 3 to 5 degrees maybe necessary to help separate the two shoulders,especially on a pt with limited flexiblity who cannot sufficently depress the shoulder away from the IR
what is the other name for the AP Wagging jaw cervical spine Ottonelle Method
what is the pathology for AP Wagging Jaw pathology involving the dens & surrounding bony structures of the C1 ring as well as the entire cervical column is demonstrated
what is the CR for the AP wagging Jaw CR perpendicular to IR,centered to C4-upper margin of thyroid cartilage
what should the mandible be doing during exposure mandible should be in continuous motion during exposure
how should you help the pt with the exposure practice with pt before exposure to ensure that only the mandible is moving continuously,& teeth do not make contact.
how should we adjust the head on a AP Wagging Jaw adjust head so that the a line drawn from lower margin of upper incisors to the base of the skull is perpendicular to table
