What are the three articulations in the hip bones?
- Pubic symphis
- Sacroiliac joint
- Hip joint

What are the two surfaces of the ilium and what attaches to each?
- Inner: concave fossa providing attachement for iliacus muscle
- Outer: Convex shape for gluteal muscle attachment
What would you not see in the hip bones of a 30 year old compared with a 15-25 year old?
In 15-25 year old you would see triradiate cartilage between the three bones, forming the acetabulum. Fusion begins at 13-15.

What are the two ligaments that attach to the ischium and what is their function?
![](https://s3.amazonaws.com/brainscape-prod/system/cm/379/742/694/q_image_thumb.png?1548966218)
- Form the sciatic foramens
- Limit rotation of the inferior part of the sacrum during transmission of weight of the body down the vertebral column when in erect position

What is the hip joint made up of?
- Synovial ball and socket joint between acetabulum and femoral head
- Ensure mobility without weakening ability of the lower limbs to support weight of the body
- Large range of movement and very stable joint

Label the osteology of the proximal femur.
![](https://s3.amazonaws.com/brainscape-prod/system/cm/379/742/733/q_image_thumb.jpg?1548967100)
- Fovea capitis for ligamentum teres with artery
- 125 degree angle with long axis of femoral shaft, slightly smaller angle in females

What attaches to the linea aspera and the gluteal tuberosity?
![](https://s3.amazonaws.com/brainscape-prod/system/cm/379/742/752/q_image_thumb.png?1548967811)
- LA: Intermuscular septa and muscles of thigh attach
- GT: site of insertion of gluteus maximus
What happens to the linea aspera towards the distal end of the femur?
Inferiorally they diverge to form lateral and medial lines.
- Medial continues inferiorly as the medial supracondylar ridge and terminates at the adductor tubercle on the medial condyle

Where is the capsule of the hip joint and what are the intra and extracapsular ligaments involved in the stabilisation of the joint?
- Attaches to edge of acetabulum to the intertrochanteric line anteriorly, and the femoral neck posteriorly.
- Iliofemoral: prevent hyperextension whilst standing without muscle activity. When sitting allows pelvis to tilt back
- Ischiofemoral: Prevents xs medial rotation of hip joint
- Pubofemoral: prevent xs abduction and extension of hip joint

What factors increase the stability of the hip joint?
- Ligamentum teres
- Cup-shaped acetabulum
- Capsule
- Acetabular labrum
- Extracapsular ligaments (pull femoral head in)
- Muscles surounding joint
What is the relationship between muscles and ligaments in the hip joint?
- Anteriorly the ligaments are stronger so few medial flexors and weaker
- Posteriorly ligaments are weaker so greater number lateral rotators and stronger
Name the main
- Flexors
- Extensors
- Abductors
- Addutors
- Lateral rotaters
- Medial rotators
And their assisters.

What factors restrict flexion and extension of the hip?
F: Unflexed knee as hamstring muscles are not relaxed
E: Iliofemoral ligament and joint capsule
