Hip Flashcards
Most significant and most stable joint
Hip Joint
Why the hip joint has the maximum stability.
It is because of the insertion of the femoral head into the acetabulum.
The most mobile joint.
Shoulder Joint
True or False: Femur has a longer neck than the humerus and more antverted.
True
How many degrees of freedom does the Hip joint have?
3 DOF: Sagittal, Transverse, Frontal Plane
This structure helps deepen and stabilize the joint.
Acetabular Labrum
The acetabular labrum is formed by your?
Ischium, Ilium, Pubis
Your Ischium, Ilium, and Pubis are also called?
Innominate Bones
This enhances the nutrition of the hip cartilage and provides a smooth, gliding surface.
Acetabular Labrum
The acetabular labrum plays a secondary role in stabilizing the hip during ________.
Hip Lateral Rotation and Anterior Translation
OPP for Hip Joint
30 Hip Flexion, 30 Hip Abduction, Slight ER
CPP for Hip Joint
Full extension, medial rotation and abduction.
CP for Hip Joint
Hip Flexion, Abduction, and Medial Rotation
Some cases, IR>F>Abd
Forces on the Hip: Standing
0.3 times the body weight
Forces on the Hip: Standing on one limb
2.4-2.6 times the body weight
Forces on the Hip: Walking
1.3-5.8 times the body weight
Forces on the Hip: Walking upstairs
3 times the body weight
Forces on the Hip: Running
4.5+ times the body weight
Anterior Ligament/s of the Hip Joint
Iliofemoral Ligament
Another term for Iliofemoral Ligament
Y Ligament or Ligament of Bigelow
The strongest ligament in the body
Iliofemoral Ligament
This structure is positioned to prevent excessive extension and limits anterior translation. It plays a significant role in stabilizing and maintaining an upright posture of the hip.
Iliofemoral Ligament
This ligament is the weakest ligament of the hip. Stabilize the hip during extension.
Ischiofemoral Ligament
Prevents excessive abduction of the femur and limits extension
Pubofemoral Ligament
Prevents excessive Internal Rotation of the Hip.
Iliofemoral, Ischiofemoral, Pubofemoral Ligament
Provides a physical attachment of the head of the femur to the acetabulum. From the foveal head, it sticks to the labrum.
Ligamentum Teres
Bursa of the Hip Joint
Trochanteric Bursa
Iliopsoas Bursa
Gluteus Medius Bursa
Ischiogluteal Bursa
The normal degrees of angle of Wiberg/Central Edge Angle
20-30 degrees
The acetabulum covers the top of the femoral head. This is measured as the intersection of a vertical, fixed reference line (stippled line) with the acetabular reference line (bold solid line) that connects the upper lateral edge of the acetabulum with the center of the femoral head.
