Unit 7 Pelvis And Hip Joints

Front 1

Bones that make up the pelvis girdle

Back 1

Two pelvic bones, sacrum and coccyx

Front 2

Pubic Sympyhsis

Back 2

fibrocarilaginous disk connects the two pelvic bones anteriorly, limited mobility unless shearing due to trauma or pregnancy

Front 3

Sacroiliac Joint (SIJ)

Back 3

articulation between sacrum and the ilium, limited mobility unless dysfunction due to muscle weakness, trauma, or pregnancy

Front 4

Sacrospinous Ligament

Back 4

connects the sacrum to the ischial spine

Front 5

Sacrotuberous Ligament

Back 5

connects the sacrum to the ischial tuberosity

Front 6

Hip Joint

Back 6

articulation between the acetabulum of the pelvis and the femoral head; triaxial, ball-and-socket joint filled with synovial fluid

Front 7

Iliofemoral Ligament

Back 7

also known as the Y ligament because of the inverted Y-shape; connects the AIIS to the intertrochanteric line of the femur; limits hip hyperextension

Front 8

Pubofemoral Ligament

Back 8

connects the pubis ramus to the femur; limits hip abduction and extension

Front 9

Ischiofemoral Ligament

Back 9

connects ischium to the femoral neck; limits hip hyperextension and internal rotation

Front 10

Ligamentum Teres

Back 10

between the acetabulum and femoral head; conduit for blood supply to the femoral head

Front 11

Acetabular Labrum

Back 11

deepens the hip socket; similar to the glenoid labrum for the shoulder
