Bony Anatomy Femur = longest and

heaviest bone in body Femoral Head Femoral Neck Greater Trochanter Lesser Trochanter Intertrochanteric Crest Intertrochanteric Line Gluteal Tuberosity

Bony Anatomy Pelvic Girdle

Acetabulum 3 bones fused together

Ilium Iliac fossa Iliac Crest ASIS = Anterior superior

iliac spine AIIS = Anterior inferior

iliac spine PSIS PIIS Gluteal Lines Greater Sciatic NotchLateral View

Acetabulum Is the large cup-shaped

cavity or socket on the lateral aspect of the hip bone

Articulates with the head of the femur to form the hip joint

The Ilium, Ishium, and Pubis join to form the acetabulum
