22 Cards in this Set

  • Front
  • Back
Coxa Vara
angle of the femoral neck to shaft < 125 deg.
normal = 125 deg.
Coxa Valga
angle of the femoral neck to shaft > 125 deg.
normal = 125 deg.
Anteversion
head and neck angled > 20 deg. in reference to a line formed by the condyles
normal = 12 deg.
"excessive angle"
Retroversion
head and neck angled < 12 deg. in reference to a line formed by the condyles
normal = 12 deg.
"flattening"
Iliofemoral Ligament
anterior capsule
resists HE
superior resists ADD
inferior resists ABD
Pubofemoral Ligament
anterior capsule
resists HE, ABD and ER
Ischiofemoral Ligament
posterior capsule
blends with iliofemoral to resist HE
resists ADD and IR
ADL's and Hip Motion
sitting, squatting, stairs, etc. require:
120 deg. FL
20 deg. ER
20 deg. ABD
Arthrokinematics
mainly rotation:
FL = posterior rot.
EXT = anterior rot.
HE = anterior rot.
ABD = medial rot.
ADD = lateral rot.
IR = medial rot. (long axis)
ER = lateral rot. (long axis)
All relative to fixed pelvis
Anterior Pelvic Tilt
ASIS = downward, anterior
sacrum = upward
Hip jt = flexion
trunk = fwd, L-spine EXT to compensate
=> increase lordosis
Posterior Pelvic Tilt
ASIS = upward, posterior
sacrum = downward
Hip jt. = EXT
trunk = back, L-spine FL to compensate
=> decrease lordosis
Lateral Pelvic Tilt
"Support Drop"
support side = lower, pelvis tilt toward support
support Hip jt. = ABD
trunk = to non-support, L-spine lateral FL to non-support to compensate
"Compensated Trendelenberg"
Lateral Pelvic Tilt
"Non-Support Drop"
support side = higher, pelvis tilted toward non-support
support hip jt. = ADD
trunk = to non-support, L-spine lateral FL to support to compensate
"Trendelenberg or Normal Gait"
Forward Pelvic Rotation
non-support pelvis = fwd
Support Hip jt. = medial and ADD
Support Femur = IR
Backward Pelvic Rotation
non-support pelvis = back
support Hip jt. = latera and ABD
support Femur = ER
Hip Flexors - Standing
iliopsoas
rec fem
pectineus
sartorius
TFL
*Adductors if Hip in HE*
Hip Flexors - Sitting
iliopsoas - main FL above 90
rec fem - can contribute if knee in full FL
Hip Extensors
glut max
biceps femoris
semimembranosus
semitendinosus
*Adductors if Hip in FL
Hip Abductors
glut med
glut min
TFL
Sartorius
Hip Adductors
adductor magnus
adductor longus
adductor brevis
gracilis
*pectineus, obturator externus, quad femoris and lower glut max can assist
Hip ERs
glut max
glut med (post)
sartorius
obturator internus
obturator externus
quadratus femoris
gemellus superior
gemellus inferior
*piriformis if hip in HE
Hip IRs
glut med (ant)
glut min
TFL
*piriformis if hip in FL
