Blueprinting and brace design Flashcards
Step 1
Verify X ray
- name
- date
- position
Step 2
Orient X-Ray
- Heart is L and stomach bubble is L.
- Liver is R.
- L or R marking on x ray is L or R on the patient.
Step 3
Vertebral identification
- Identify T12: last rb
- Identify vertebrae from T1 to L5.
Step 4
Draw a centerline vertically from middle of S1
Step 5- decompensation
Bisect C7 spinous process. Measure distance to midsagittal.
Step 6- pelvic line
Draw horizontal line across crests.
use shoe lift if pelvis is not level.
Step 7- IVT (intervertebral tilt)
Each vertebrae, draw direction of tilt.
Measure each angle using a protractor
Step 8- Determine apex or null point
Determine where angular tilts change.
Want pressure at apex and below
Step 9- draw module outline
Determine width of posterior opening- width of L5 vertebral body
Draw iliac crest rolls- centered over L2-3
Step 10- determine direction of tilt of L5
Put trochanteric pad on side of tilt.
On the side of truncal decompensation
Step 11- draw lumbar pad
extends from apex of lumbar vertebrae below to all vertebrae tilted in that direction.
Step 11- draw thoracic pad
extends from apical rib vertebrae down to crest roll
Step 12- draw axillary extension
Starts at directional tilt change of thoracic vertebrae upwards.
Step 13- consider derotation pads
ASIS
Anterior thoracic
Anterior lumbar
When to use a lumbar scoliosis brace?
Highest component is lumbar pad.
- lumbar curves
- TL curves where patient is decompensated to convex side.
- double curves with flexible thoracic curve.
