Rotational Profile Flashcards
6 Measures of Rotational Profile
Foot Progression Angle
Medial and Lateral Hip Rotation (PROM)
Ryder’s Test (Anteversion)
Thigh-Foot Angle
Transmalleolar Axis (Thigh Angle)
Foot Configuration
Foot Progression Angle
Assessing how feet land in relation to straight line during gait
Ryder’s (Craig’s) Test
Hip Anteversion test
Palpate greater trochanter and passively IR until GT feels most prominent
Measure angle between line that bisects tibia and vertical line protruding from table
Hip Anteversion vs. Retroversion
Anteversion: Inward rotation of Femur in relation to the knee
Retroversion: Outward rotation of Femur in relation to the knee
Thigh Foot Angle
Taken with knee flexed
Assessing degree of tibial torsion
Should ALWAYS be external
Transmalleolar Axis (Thigh Angle)
Can assess with knee flexed or extended
Assessing tibial torsion
Newborn Norm Values
Anteversion / Transmalleolar Axis / Thigh-Foot Angle
Anteversion: 40 degrees
TMA: 0 degrees
TFA: 5-10 degrees internal
2-Year-Old Norm Values
Transmalleolar Axis
10-15 degrees external
5-Year-Old Norm Values
Anteversion / Transmalleolar Axis / Thigh-Foot Angle
Anteversion: 23-26 degrees
TMA: 20-30 degrees external
TFA: 10 degrees external
8-Year-Old Norm Values
Anteversion / Transmalleolar Axis
Anteversion: 20 degrees
TMA: 20-30 degrees external
15-Year-Old Norm Values
Anteversion / Transmalleolar Axis / Thigh-Foot Angle
Anteversion: 10-15 degrees
TMA: 20-30 degrees external
TFA: 12-30 degrees external
Adult values achieved
Absolute vs. Relative Retroversion
Absolute: <10 degrees Anteversion
Relative: < or = 0 degrees Anteversion
Intoeing Characteristics
Hip
Tibia
Foot
Toe
Hip: Medial femoral torsion
Tibia: Medial tibial torsion
Foot: Metatarsus Adductus
Toe: “Searching” Toe
Outtoeing Characteristics
Hip
Tibia
Foot
Hip: Infant (physiologic)
Tibia: Lateral tibial torsion
Foot: Everted (flat) foot
Q Angle
Relationship between 2 lines - ASIS to patella + patella to tib tub
Norm: 15-20 degrees
What conditions at the Hip and Tibia are associated with an increased Q Angle?
Hip Anteversion
External tibial torsion
Q-Angle > 20 degrees
What conditions at the Hip and Tibia are associated with an decreased Q Angle?
Hip Retroversion
Internal tibial torsion
Q-Angle < 15 degrees
“Miserable Malalignment”
Knees in, toes out
Excessive Anteversion
External Thigh Foot Angle (excessive)
Squinting Patella
Transverse plane deviation
Malrotation of femur and tibia that presents like a valgus knee deformity
