use of the pelvic symphysis
- It joins the pubis and ischium of the 2 hip bones
- It’s a secondary cartilaginous joint which ossifies with age
- Ossification begins at the pubis and moves caudally
use of the sacro-iliac joints
- They combine a synovial joint with an adjacent area of fibrous union
- This is thought to allow a firm joint with a degree of shock absorption
use of the sacrotuberous ligament
- In the dog, it is a stout cord which runs from the transverse processes of the last sacral and 1st caudal vertebrae to the lateral angle of the ischiatic tuberosity
- Serves as point of attachment for biceps femoris muscle
- The ligament is absent in the cat
use of the hip joint
• It’s a ball-and-socket joint whose movements are flexion and extension
use of the ligament of the femoral head
- It’s a thick band of collagenous tissue that extends from the acetabular fossa to the fovea capitis
- Prevents dislocation of hip joint
use of the transverse acetubular ligament
- It’s a small band that extends from one side of the acetabular notch to the opposite side
- It continues to the acetabular lip which deepens the acetabulum to keep the femur head solidly in place
