|
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 |
