Hip Lecture Notes Flashcards
(14 cards)
Why is the hip the strongest and most stable joint in the body?
!. Sturdy bony alignment
- Ligamentous arrangement
- Dynamic muscular support
Only 2 bony prominences in the hip, what are they??
Hard to palpate
- Ischial tuberosity
- ASIS
* **A 3rd is nearly palpable=Greater trochanter of the femur
The Labrum:
- Thicker & Stronger superiorly
- Deepens the Acetabulum by 21%
- Similar in vascularity as the meniscus of the knee
Joints of the hip:
- Pubic Symphysis - interpubic discs allow small amount of distraction/compression & rotation.
- Sacroilac (SI) - Ilium & sacrum; combination of synovial & syndesmotic joints;
- coxofemoral ligament
Walking and running require tremendous support of _____ forces moving through the hip
Kinetic
When standing on one leg, ____’s body weight is transmitted through the hip
When jogging, up to ____’s body weight is transmitted through the hip
3-4x
8x
Muscles of walking and running: Swinging phase
Rectus femoris, iliopsoas
Muscles of walking and running: Deceleration phase
(Extend hip/decelerate knee) hamstrings
Muscles of walking and running: Propulsion phase
(hip flexion and knee extension) Rectus femoris, iliopsoas
Name the hip adductors and motion
ADDuct & INTernaly Rotate
Gracilis, adductor magnus, adductor longus, adductor brevis, pectineous
Name hip abductors and motion
ABDuction & horizontal stabilization
Gluteus Medius & TFL
Trendelenburg’s gait; hip drop test strength of medius
Intrinsic muscles of the _____ hip are crucial in controlling hip in loading and midstance gait
internal rotation
What are the hip extensors?
Gluteus maximus & gluteus mediaus
hamstring is also important as eccentric decelerator (hip flexion & knee extension)
