  1. Anatomy & Kinesiology Part II: the Hip and Pelvis Jan McElroy PT, MS, PCS 2009 Do not copy without permission

  2. Hip & Pelvis

  3. Hip & Pelvis: skeletal system

  4. Overview The pelvis is made up of 2 innominate bones which meet: anteriorly at the pubic symphysis and posteriorly at the sacrum Sacrum Innominate bone Pubic Symphysis Innominate bone

  5. Pelvis The innominate bone is made up of 3 fused bones: Ischium Ilium Pubis Ilium Anterior view Ilium IIschium pubis Lateral view

  6. Landmarks Important landmarks to note are: Iliac Crest Anterior-superior iliac spine (ASIS) Posterior-superior iliac spine (PSIS) Ischialtubersosity(also called the I.T.s, the ischial “tubes”, or your “sit bones” Acetabulum Lateral view

  7. The hip When we talk about the hip we are referring to the articulation between the acetabulum of the pelvis and the head of the femur. The hip joint is a ball and socket joint.

  8. femur The femur is the longest and strongest bone in the body. The shape of the proximal portion of the femur changes dramatically from infancy to adulthood. Femur- Anterior view

  9. Femur: landmarks Head Neck Greater trochanter Lesser trochanter Shaft Linea aspera Lateral condyle Medial condyle Left Femur- Anterior view Left Femur- Posterior view

  10. Hip & Pelvis: muscular system

  11. Quadratus lumborum • Psoas Minor • Psoas Major Muscles from the Pelvis to the spine Note: the Psoas major and minor muscles span both the lumbar spine and the hip, therefore are 2 joint muscles. Anterior view From: Novartis Interactive Atlas, Frank Netter artist

  12. Iliopsoas(Iliacus, psoas major & minor) • Quadriceps(rectus femoris, vastusmedialis, vastuslateralis, vastusintermedialis • Sartorius Anterior muscles of the hip Anterior view right thigh From: Novartis Interactive Atlas, Frank Netter artist Anterior view

  13. Adductor brevis • Adductor longus • Adductor magnus • gracilis Medial Muscles of HIP Anterior view Right thigh Anterio-medial view, right thigh

  14. Gluteus maximus • Gluteus medius • Gluteus minimus • Hamstrings • Biceps femoris • Semitendinosus • semimembranosus • Iliotibital tract (also called the IT band) Posterior muscles of hip Posterior view right thigh
