Hip Joint Flashcards
What type of joint is the Hip Joint?
Ball and Socket
(same as glenohumeral joint)
What is the Angle of Inclination of the femur?
The angle of inclination of the femur refers to the angle formed between the femoral neck and the femoral shaft. This angle plays a crucial role in determining the alignment of the hip joint and influences the overall function of the lower limb.
135º in 3 - year old child
126º in young adult
120º at old age
What is the average angle of inclination of the femur?
How does it differ between men and women?
Average is between 125º - 130º
It is greater in females becasue they have a wider pelvis
What is the Torsion angle of the Femur?
The torsion angle of the femur refers to the degree of rotation or twist along the long axis of the femur bone. It indicates the orientation of the femoral neck and head in relation to the femoral condyles at the knee.
The normal range for femoral torsion in humans is typically around 10 to 20 degrees of anteversion.
What are Ateversion and Retroversion of the Femur?
Anteversion means that the femoral neck and head are rotated forward in relation to the condyles, creating a slight twist. Retroversion, on the other hand, would indicate a backward rotation.
How does the Femur articulate with the pelvis?
femoral head fits into the acetabulum, creating a ball-and-socket configuration.
Both the acetabulum and the femoral head are covered with articular cartilage, which is a smooth, slippery tissue that allows for smooth movement and reduces friction between the bones.
Surrounding the hip joint is a fibrous joint capsule that encloses the articulating surfaces. This capsule helps to stabilize the joint.
What ligaments connect the head of the femur to the acetabulum?
Ligament of head of Femur
Acetabular Labrum
Transverse Acetabular Ligament
Ligament of head of Femur
runs from the fovea capitis on the head of the femur to the acetabular notch within the acetabulum of the hip bone
Acetabular Labrum
The acetabular labrum is a ring of fibrocartilage that runs around the outer rim of the acetabulum.
Transverse Acetabular Ligament
This ligament is a thickening of the inferior part of the acetabular labrum, running across the acetabular notch.
Ligaments connecting the Femur to Pelvis
3
Iliofemoral
Pubofemoral
Ischiofemoral
Iliofemoral
This is the strongest of the three ligaments and forms a Y-shaped structure. It runs from the anterior inferior iliac spine (AIIS) and the acetabular rim to the intertrochanteric line on the femur.
Pubofemoral
This ligament runs from the superior pubic ramus to the intertrochanteric line and neck of the femur.
Ischiofemoral
The ischiofemoral ligament extends from the ischium to the greater trochanter of the femur.
