Lower extremities exam 3- hip Flashcards
normal angle of inclination
125 deg
coxa vara def
decreased angle of inclination
coxa valga
increased angle of inclination
how does the angle of inclination change throughout a human’s lifespan
start w/ high and decreases as weight bearing begins
def angle of inclination
angular relationship of femoral head and femoral shaft of frontal plane (at hip joint_)
angle of torsion def
angular relationship of femoral head and femoral shaft in the transverse plane= amount of twist on the femur
angle of torsion normal degree
15-20
angle of torsion anteversion
greater than 20
angle of torsion retreoversion
less than 15
hip/femoral anteversion degree
greater than 20
what may femoral anteversion lead to
increase of Q angle, internal femoral rotation, squinting patella
hip/femoral retroversion degrees
less than 15
what does femoral retroversion lead to
femoral ER, laterally positioned patella, toe out gait
bones of hip and pelvis
ilium, pubis, ischium, sacrum, coccyx, femur
what 3 bones make up the pubis
superior rami, inferior rami, symphysis
where is the ishium located anatomically
at the fold of the buttcheek where hamstrings insert
innominate bone made up of what 3 hip structures
illium, ishium, pubis
what makes up the socket of the hip joint
acetabulum and labrum
what bone makes up the tail bone
coccyx
what quad muscle crosses at the hip
rectus femoris
what are the anterior muscles of the hip
rectus femoris, sartorius, illiopsoas
medial muscles of hip
adductors, gracilis
lateral muscles at the hip
gluteus medius, IT band, piriformis, quadratus femoris, obturator internus, obturator externus, gemellus superior, gemellus inferior
posterior muscles at the hip
glutes and hamstrings
trochanteric bursa purpose
provides lubrication for where gluteus maximus passes over greater trochanter, IT band, hip abductors
gluteofemoral bursa def
separates gluteus maximus from origin of vastus lateralis
ischial bursa def
weight bearing structure when person is SEATED provides cushioning
iliopsoas bursa
LARGEST bursa in the body, covers AIIS, illiac fossa, lesser trochanter
muscles involved in hip flexion
illiacus, psoas, sartorius, rectus femoris, pectineus, adductor brevis, adductor longus, adductor magnus, gluteus medius, gluteus minimus
muscles involved with hip extension
adductor magnus, gluteus maximus, gluteus medius, biceps femoris, semimembranosus, semiteninosis
what can the clinican do to isolate the glute instead of allowing the hamstring to fire?
have patient lay prone and flex the knee to prevent hamstring from working
muscles involved with abduction
sartorius, tfl, piriformis, gluteus maximus, gluteus minimus, gemellus superior, gemellus inferior, obturator internus
muscles involved with adduction
pectineus, adductor brevis, adductor longus, adductor magnus, gracilis, gluteus maximus
muscles involved with internal rotation
tfl, gluteus medius, gluteus minimus, semimembranosis, semitendinosus
muscles involved with external rotation
psoas, illiacus, sartorius, adductor brevis, gluteus maximus, gluteus medius, piriformis, inferior gemellus, obturator internus, quadratus femoris
what’s the artery at the hip
femoral artery
what does the femoral triangle include
sartorius, adductor longus, inguinal ligament
L1 DTR
L1 & L2 DTR which nerve
femoral nerve
what nerves are involved with the lumbar plexus
femoral, obturator, sacral
special test for angle of torsion set up
prone w/ knee flexed to 90, one hand palpates greater trochanter and uses a goniometer to measure.
special test for angle of torsion do
rotate femur until greater trochanter is maximally prominent, angle is measured by lower leg while knee remains flexed to 90
special test for angle of torsion + test
angle greater than 15 deg created after femur moved= femoral retroversion. angle greater than 20 deg created after femur moved= anteversion
q angle degrees m/f
18 deg F, 13 deg M
q angle def
relationship b/w ASIS, midpoint of patella and tibial tuberosity
leg length discrepancy special test *true
ASIS to medial malleolus
leg length discrepancy special test *apparent
umbilicus to medial malleolus
trendelenburg test set up
patient standing w/ weight evenly distributed on both feet, iliac crests or posterior superior iliac spines should be visible
trendelenburg test do
patient lift leg opposite of side being tested
+ trendelenburg test
pelvis lowers on non-weight bearing side
what does + trendelenburg test indicate
glute medius weakness
thomas test setup
patient supine, passively flex knee to chest and opposite leg rests on table
+ thomas test
involved leg rises off table OR involved knee moves into extension
+ thomas test indicates
tightness of iliopsoas OR rectus femoris
ely’s test set up
patient prone, passively flex knee
ely’s test +
hip on side flexes causing it to rise from the table
ely’s test + indicates
tightness of rectus femoris
faber(patrick’s) test set up
patient supine with involved foot crossed over opposite thigh, one hand on ASIS and other on medial flexed knee
+ patrick’s test
reproduction of symptoms at hip
patrick’s test indicative of
impingement at hip, labral tear,
what test should be done for the labrum of hip
faber (opposite) and anterior impingement (anterior), hip scouring (internal and external rotation), trendelenburg
piriformis test set up
patient laying on side, top leg positioned w/ hips at 60 deg flexion and knee flexion, stabilize pelvis and apply downward pressure at knee
piriformis test +=

piriformis test + indicates
piriformis tightness or piriformis syndrome
anterior impingement test set up
patient supine, flex IR and adduct hip, rotate leg out
