L &S Spine
Question | Answer |
---|---|
Lordoctic | Convex (Cervical and Lumbar) |
Kyphotic | Concave (Thoracic, and Sacral) |
Scottie Dogs are on what vertebrae | Lumbar |
Evaluation Criteria for AP L-spine | T12 to S1, No rotation, spinous processes are centered to the bodies, SI joints are equidistant from vertebral column, Psoas muscles visualized |
CR for Lateral L-Spine (Lumbosacral and Lumbar only) | Lumbosacral CR enters at pt illiac (L4), 1.5 inch above crest for Lumbar only, If spine is not horizontal then caudad angle 5 to 8 degrees |
What does Lateral L-spine demonstrates | intervetebral foramina |
Evaluation Criteria for Lateral L-Spine | Lower thoracic spine to the Coccyx, intervertebral disk/ foramina open, Superimposed crest, Spinous Processses in profile |
LATERAL SPOT L5-S1 CR | CR posterior to ASIS and 1.5 inches inferior to iliac crest 5-8 degree caudad |
SPOT Evaluation Criteria | L5-S1 demonstrated, L5-S1 intervertebral disk space open, Ilia closely superimposing each other |
AP Oblique (RPO/LPO) L-Spine CR | 1-1.5 inch above iliac crest 2 inch medial to elevated ASIS |
AP Oblique (RPO/LPO) Evaluation Criteria | Pedicle near the center of the vertebral body |
what does it mean If the pedicle is anterior on the vertebral body? | the pt is not rotated enough (under-rotated) |
what does it mean If the pedicle is posterior on the vertebral body? | the pt is rotated too much (over rotated) |
What do oblique projections demonstrate? | Zygapophyseal joints |
