The pelvis is made up of 2 innominate bones which meet: anteriorly at the pubic symphysis and posteriorly at the sacrum Innominatebone Sacrum Innominatebone Pubic Symphysis
The innominate bone is made up of 3 fused bones: 1. Ischium 2. Ilium 3. Pubis Ilium IIschium pubis Anterior view Lateral view
Important landmarks to note are: Iliac Crest Anterior-superior iliac spine (ASIS) Posterior-superior iliac spine (PSIS) Ischial tubersosity (also called the I.T.s, the ischial “tubes”, or your “sit bones” Acetabulum Lateral view
When we talk about the hip we are referring to the articulation between the acetabulum of the pelvis and the head of the femur. ball and socket joint The hip joint is a ball and socket joint.
