Lordosis Flashcards
When in the physical exam would you discover abnormal lumbar lordosis?
part of screening exam; symmetry/asymmetry
mid-gravity line
spinal curve assessment
What somatic dysfunction can increase lordosis?
cervical extended segments thoracic flexed segments lumbar extended segments anterior innominate rotation sacral flexed dysfunctions
How would you measure the lateral mid-gravity line?
extend from mid-body of L3 and should fall at front of sacral promontory
What is a normal Fergusen Angle?
30-40 degrees
What is a normal Mitchell angle?
125 to 145 degrees
How do you measure a Mitchell angle?
line through mid-body l4/L5 and line through mid-body of S1/S2
How do you measure a Fergusen angle?
horizontal line and line on top of sacral promontory
What is Baastrup?
kissing spines
How could you measure a Cobb angle for a lumbosacral lordotic angle?
line at superior endplate of L2 and line at superior endplate of S1
What is a normal Cobb angle when L2 and S1 endplates are used?
40 to 60 degrees
What is the normal Cobb angle when L2 and L5 endplates are used?
35 to 55 degrees
How is the Jungman’s pelvic index computed?
PI = x/y x= front of pubic bone to y y= front of sacral promontory to line x
What is the normal ratio at 20? 50?
20 = 0.55 50 = 0.65
At what Junman’s PI does chronic LBP occur?
0.65-0.75
Increased lumbar lordosis can increase weight bearing on ?
facets causing facet joint pain
Increased lumbar lordosis causes narrowing of?
intervertebral formina with neural entrapment
