FAB - Scoliosis

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.

In a normal spine, what is the normal lateral curvature?   5 degrees  
What % of ppl is lateral curve to the right?   85%  
What is definition of scoliosis?   Any lateral deviation of spine of more than 10 degrees  
What is degree range for mild scoliosis?   10-20 degrees  
What are the 2 shapes of scoliosis?   C-shaped or S-shaped  
What are the 2 categories of scoliosis?   Functional & Structural  
What is the cause of functional scoliosis?   Effects of soft tissue, muscles, tendons, ligaments  
Adams test   Flex at waist. If lat. curve straightens out, then functional. If not, then structural.  
What causes structural scoliosis?   bony changes  
What is the Lateral Bending test?   After Adams test, for structural scoliosis; Pt lateral bends, scoliotic curve increases.  
What are 2 types of structural scoliosis?   Developmental & Acquired  
What causes developmental, structural scoliosis?   Bony abnormality which occures during development  
Up to what age can developtmental scoliosis be seen?   20 yrs old  
What are the common bony abnormalities that can be seen in developmental scoliosis?   Hemivertebra, spina bifida, posterior element defect  
What is Posterior element defect?   When parts of the posterior elements (lamina, pedicles) of the vertebra do not develop completely.  
What are 5 causes for acquired scoliosis?   Trauma; neuromuscular dystrophy; infection; Idiopathic  
What is the more common cause of structural scoliosis?   Idiopathic.  
How does the coupled motion change in scoliosis?   Coupled motion of rotation and lateral bending REVERSES  
Where does the reversal of coupled motion occur?   only within scoliotic region & only with structural scoliosis  
Lovett positive association   Seldom symptomatic and least offending  
Lovett negative association   Severe pain  
Lovett Static association   Symptomatic w/ moderately severe pain  
Lovett Failure association   Profile of lumbar spine disc prolapse  
Lovett positive SP orientation   SPs are on side of concavity and on high side of sacrum  
Lovett Negative SP orientation   SPs are on side of convexity and on low side of sacrum  
Lovett Static SP orientation   SPs are in midline on side of convexity; Sacrum is off 20 degrees  
Lovett Failure SP orientation   SPs are in midline; Sacrum is off 20 degrees  
Lovett Excess SP orientation   SP are on side of concavity and on high side o sacrum  
Lovett Reverse SP orientation   SPs are in midline, Lumbar spine goes in opposite direction; Sacrum is off 20 degrees.
