advanced positioning scoliosis, lumbar flexion and extension

QuestionAnswer
What is lumbar spine fusion radiography used for? to determine if there is motion in the area of a spinal fusion, and evidence of structural change with scoliosis, and localization of herniated disks
When is lumbar spine fusion performed? 6 months after surgery
How do we achieve maximum right lumbar bending on a radiograph? pt. crosses the left leg over the right, move both heels toward the side that is flexed and immobilize with sandbags and move both shoulders laterally toward the flexed side.
CR entry for AP L-spine with R or L bending perpendicular to L3 (1 1/2” above the crest)
Lateral hyperflexion and hyperextension spines are used to: determine if motion is present in an area of spinal fusion and localize herniated disks
Lateral hyperflexion L-spine pt. position pt. leans backward as much as possible, extending limbs as much as possible
Lateral hyperextension L-spine pt. position pt. leans forward and draws the thighs up forcibly
CR entry for hyperflexion/extension L-spine area of spinal fusion or to L3
3 main patient prep points for scoliosis radiography remove shoes, close collimation, PA projection
Where is the IR lined up for scoliosis radiography? BOF to include 1” of iliac crests
First scoliosis radiograph pt. stands normally in front of IR, checks the spinal curvature
Second scoliosis radiograph distinguishes the primary from the secondary curvature – elevate pt. foot on the convex side of the primary curve 3-4”
CR entry for scoliosis entering to the midpoint of the cassette
T-spine scoliosis films include what projections? PA erect, PA prone, PA prone R lateral flexion, PA prone L lateral flexion
