lab 9: Rotational Profile Flashcards
What is typical values for LE rotational profile for a newborn?
anteversion: 40
transmalleolar axis: neutral
thigh foot angle: 5-10 IR
What is normative values for rotational profile of a 2 year old? (walking)
10-15 degrees of ER transmalleolar axis (starting to derotate their femurs, less than 40 degree anteversion)
What is the normative values for a rotational profile of a 5 year old?
anteversion: 23-26
transmalleolar axis: 20-30 ER
thigh foot angle: 10 ER
What is the normative values for a rotational profile of a 8 year old?
anteversion: 20
transmalleolar: 20-30 ER
thigh foot angle: between 10-30 (12-30 ER is for 15 year old)
What is the normative values for a rotational profile of a 15 year old?
anteversion: 10-15
transmalleolar: 20-30 ER
thigh foot angle: 12-30 ER
typical adult transmalleolar axis is 20-30 degrees of external rotation: T or F
true
Typical thigh foot angle of an adult should be
12-30 degrees of EXTERNAL ROTATION
What should you make sure is neutral when you measure thigh-foot angle?
subtalar joint
T or F: thigh foot angle tells you only bony reason for IR/ER
F: could be muscle tightness/spasticity, we don’t know
What is miserable malalignment?
When tibia is a rebel and opposes a mal-aligned femur
(hip IR, tibial ER, squinting patella)
miserable malalignment is common in populations that do not WB normally, such as ____
Cerebral palsy
*excessive anteversion not corrected through walking
Sometimes, kids with hemiplegia CP GMFCS level 2 or 3, can walk but cannot run (they trip and fall). Why is that?
They walk with their hemi pelvis rotated back, so they seem normal walking (no intoeing) but trip when running.
Standard of care with ortho surgery to improve gait includes what before being cleared for surgery?
3D motion analysis lab for gait
*catches transverse plane abnormalities
10 year old with spastic hemiplegic CP functioning at GMFCS level 3: limited hip movement and lumbar lordosis.
What Winters classification describes this gait pattern?
4
in-toeing ambulation eval: 18 yr old
passive HIP IR: 70
passive HIP ER: 20
hip anteversion: 35
transmalleolar axis: external 20
thigh foot angle of 20
typical forefoot to heel alignment
what is best clinical finding?
excessive hip anteversion
if thigh foot is INTERNAL 20, then would be abnormal.
what would most likely be found in a 15 year old patient with miserable malalignment?
hip anteversion high with high external thigh foot angle or high external transmalleolar angle
