Kines Hip Flashcards
How much does the acetabulum face inferior in men vs women
There is a 22-42 range
Men: 38 degrees
Women: 35 degrees
What is another name for Right Pelvic External rotation
Left pelvic backwards rotation
What sections of the pelvis make up the posterior portion of the acetabellum
Ischium
How will a compensated retroversion present
External rotation of the LE
Toes are pointed out
Arthrokinematics of OCK IR
Anterior Roll Posterior Glide
Describe the structure of the proximal femur
It is more spherical than the acetabulum
Has a fovea capitis
What are the Transverse plane motions of the hip and the normal values
IR in extension (0-55) IR in Flexion (0-45) ER in extension (0-55) ER in Flexion (0-45)
Explain Right Pelvis Drop
Left leg is on ground as the axis of rotation
- The right pevis will depress
- Lumbar will bend to the right
Arthrokinematics of OCK Adduction
Inferior Roll Superior Glide
How will a tight iliopsoas present
Tight illiacus= anterior tilt of pelvis
Tight psoas major= Lumbar lordosis
What is retroversion
When the angle of “version” is less than 8-15 degrees or in a lateral torision
What are the medial rotators of the hip
- There are no muscles with a primary function of IR
- The TFL and glute medius (anterior fibers) may play the largest roles.
- Glute minimus
- Piriformis if the beyond 90 degrees of flexion
Explain the angle of inclination of the proxima femur and how it changes with age
Has a frontal plane inclination that gives the body its
What adductor will cross both the knee and the hip
The Gracillis
What are the primary muscles for lateral rotation of the hip
- Obturator internus
- Piriformis
- Obturator externus
- Quadratus femoris
- Sperior Gemellus
- Inferior gemellus
Explain Right hip Hiking
The Left leg with the femur in the acetabellum acts as the axis of rotation.
- The right pelvis ill elevate
- Lumbar will bend to the left
What will a greater angle of inclination result in on the lower extremity
Increased leg length
More of a valgus
What will limit the rotation of the hip while the hip is in 90 degrees of flexion
The posterior capsule
What are the sagittal plane motions and values for the hip
Flexion (0-120) Extension (0-20)
What will coxa valga result in for the lower extremity
Increased leg lenght
Increased pre-load to the abductors
Decreased moment arm of abductors
