| Question |
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. |
