Heel lift height is Sacral base unleveling
based on? Short leg syndrome
Measured to tx? Heilig
Based on what
formula?
7. When should Heel lift should be considered when the femoral head ditterence is >5mm
heel lift be con-
sidered? 10-12mm (1/2in) is max heel lift, patient needs to be built up to this #.
Max heel lift pos-
3 mm every 1-2 weeks (1.5mm for fragile people)
sible?
Heel lifts should
Final heel lift height should be ½ to ¾ the measured leg length discrepancy for
be increased by
long standing discrepancies
(# mm) every
. Final heel lift height should be the full leg length discrepancy for suddenly
Goal of heel lift? acquired discrepancies
8. Short leg syn- 1) Sacral base will be lower on the side of the short leg
drome findings
2) The innominate will be rotated anteriorly on the short side
3) Lumbar spine will be sidebent away and rotated toward the short leg side.
9. Most common Hip replacement
cause of short leg
syndrome
10. Rules for Sacral 1) Sidebending of L5 and the sacral oblique axis must be engaged on the same
Somatic Dysfunc- side.
tion (4):
2) The sacrum rotates in the opposite direction of L5.
3) The seated flexion test must be positive for the diagnosis of sacral torsion.

4) The seated flexion test will be positive on the side opposite of the oblique axis.
11. Positive spring Backward sacral torsion
test indicates
what?
12. Anatomy Review: Sciatic nerve--> Tibial + Common Fibular (peroneal) nn.
Branching of Sci-
atic Nerve CFN--> Superficial + Deep Fibular
13. Common fibular Fibular head
nerve is most
susceptible to in-
jury at which
anatomical loca-
tion?
14. Name of the fxn Plantar flex, evert foot. Dorsal skin sensation
of the following
nerves: Dorsiflexion, invert foot. Toe dorsiflexion. Skin sensation b/w digits 1 and 2.
1) Superficial
fibular
2) Deep fibular
15. Cranial Nomen- Cranial flexion = counter-nutation = non-cranial extension
clature
Cranial extension = nutation = non-cranial flexion
16. Motion of paired Flexion--> External rotation
bones in cran- Extension--> Internal rotation

tension
