| Term | Definition |
|
Sacroiliac Joint |
between the auricular surface of the sacrum and the arricular surface of the ilium |
|
The sacroiliac joint is what kind |
a synovial plane joint |
|
The SJ has what type of surface |
very irregular surface for stability |
|
The SJ allows what movement |
little, except at childbirth |
|
Nutation |
the superior sacrum moves anteriorly relative to the pelvis |
|
Counternutation |
when the inferior sacrum moves anteriorly relative to the pelvis |
|
Ligaments of the SJ are |
Anterior & Posterior sacroiliac, interosseous sacroiliac, sacrotuberous, sacrospinous, iliolumbar |
|
The SJ transmit weight from |
the spine to the LE |
|
The anterior and posterior lig. of the SJ do what |
reinforce the joint capsule |
|
Interosseous sacroiliac lig does what |
fill in the space between the sacrum and the ilium |
|
Sacrotuberous lig does what |
connects the sacrum to the ischial tuberosity |
|
Sacrospinous lig does what |
connects the scarum to the ischim spine |
|
Iliolumbar ligament does what |
connects L4 and L5 vertebrar to the ilium |
|
Public symphysis is 2 public bones connected by what |
fibro cartilage |
|
The pubic sym is supported by what |
superior, inferior and posterior pubic ligaments |
|
The pubic sym has what type of movement |
very little except at childbirth |
|
Pelvic motions include |
anterior pelvic tilt, posterior pelvic tilt, hip hiking, pelvic rotation |
|
anterior pelvic tilt is |
ASIS moves anteriorly |
|
posterior pelvic tilt is |
ASIS moves posteriorly |
|
hip hiking is |
occurs during walking and open chain abd. |
|
pelvic rotation is |
trunk rotation occurs during walking and turning the body |
|
Hip Joint is located where |
between the lunate surface of the acetabulum and the head of the femur |
|
The hip joint is what kind of joint |
ball and socket |
|
Normal flexion for hip joint |
120 |
|
Norm extension for hj |
30 |
|
norm adb for hj |
45 |
|
norm add for hj |
30 |
|
norm IR/ER for hj |
45 |
|
functional ROM for sitting for hj |
85 |
|
functioal ROM for climbings stairs for hj |
65 |
|
functional ROM for standing up for hj |
100 |
|
Ligaments of HJ |
Ligamentum teres, iliofemoral ligament/Y lig, pubofemoral lig, ischiofemoral lig, inguinal lig |
|
Ligamentum teres |
connects the fovea of the femur to the acetubular rim |
|
ligamentum teres does what |
route for nerves and secondary blood suppy to reach the femoral head |
|
iliofemoral lig/Y lig |
inverted Y shaped lig, that reinforces the anterior capsule |
|
iliofemoral lig does what |
limits hyperextension of the hip and allows paraplegics to stand with leg braces |
|
pubofemoral lig is located where |
interior to iliofemoral ligament, pubis to femur |
|
pubofemoral lig does what |
reinforces the anterior capsule |
|
ischiofemoral ligament |
reinforces the posterior capsule |
|
Inguinal ligament does what |
connects the ASIS and the public tubercle, dividing the abdomen from the thigh |
|
inguinal ligament also allows |
nerves, blood vessels and lymphatice vessels pass under it when traveling to the LE |
|
Resting postion for hip |
30 flexion and abd, slight external rotation (lounging with feet propted up |
|
closed packed - ligamentous |
full ext, abd, and IR of hip |
|
closed packed - bony |
sitting 90 flexion, slight ER |
|
Acetabular labrum |
ring of the fibro cartilage that deeps the actetabular to increase stability |
|
Iliotibial band (IT) |
thick fasia that runs down the lateral thigh and help conteract the bending force place on the neck of the femur during weight bearing |
|
Angle of inclination |
measure in frontal plane |
|
angle of inclination is located |
between the head of the femur and the shaft |
|
Angle of inclination is larger when |
during childhood, decrease to 115 to 140 in adults |
|
angle of inclination pathological increase |
coxa valga |
|
angle of inclination pathological decrease |
coxa vara |
|
angle of torsion is mearsure in what plane |
transverse |
|
angle of torsion is the angle of |
twist from the neck of the femur to the femur condyles |
|
angle of torsion |
decrease with age normal is 10 -20 in adults |
|
angle of torsion pathological increase |
antiversion |
|
angle of torsion pathological decrease |
retroversion |
