1 Os Coxa: The fusion of 3 bones during childhood Ilium ischium pubis

2 Acetabulum Obturator foramen OS COXA

3 Lateral and Medial Views of the Hip Bone Figure 8.8b, c Ilium Ischium Pubis Ilium Ala Tubercle of the iliac crest Anterior gluteal line Posterior gluteal line Posterior superior iIiac spine Greater sciatic notch Posterior inferior iliac spine Ischial body Ischial spine Lesser sciatic notch Ischial tuberosity Ischium Ischial ramus Inferior gluteal line Acetabulum Pubic body Iliac crest Anterior superior iliac spine Anterior inferior iliac spine Pubis Inferior ramus of pubis (b) Lateral view, right hip bone Iliac fossa Ilium Iliac crest Anterior superior iliac spine Anterior inferior iliac spine Arcuate line Pubic tubercle Superior ramus of pubis Inferior ramus of pubis Posterior superior iliac spine Obturator foramen Body of the ilium Ischium Ischial ramus (c) Medial view, right hip bone Auricular surface Ischial spine Posterior inferior iliac spine Articular surface of pubis (at pubic symphysis)

4 Iliac crest Iliac fossa Anterior superior iliac spine Anterior inferior iliac spine Posterior superior iliac spine Greater sciatic notch ILIUM Posterior inferior iliac spine

5 Greater sciatic notch Lesser sciatic notch ILIUM Arcuate line Auricular surface and sacroiliac joint Ischial spine

6 Ischial tuberosity Lesser sciatic notch Ischial spine ISCHIUM Anterior

7 Ischial spine Lesser sciatic notch Ischial tuberosity Pubic bone ISCHIUM Posterior

8 PUBIS Inferior ramus Superior ramus Pubic bone

9 PUBIS Pubic symphysis Pubic arch Symphyseal surface

10 Female pelvis Male pelvis

11 Pubic arch is broader in female Pubic arch is narrower in male Female pelvis Male pelvis Pelvic brim

12 Female pelvis Male pelvis

13 How to tell and right and left os coxa Place the auricular surface against the clothing on your hip, with the pubis facing anteriorly. The acetabulum should point laterally.

14 FEMUR Head Neck Greater trochanter Lesser trochanter

15 FEMUR Greater trochanter Lesser trochanter Head Neck Intertrochanteric crest

16 Intertrochanteric crest (posterior) Intertrochanteric line (anterior)

17 FEMUR Gluteal tuberosityLinea aspera Medial condyle Lateral condyle Popliteal fossa Intercondylar notch

18 FEMUR Medial epicondyle (adductor tubercle) Medial condyle Lateral condyle

19 How to tell right from left femur? Place the femur on the anterior surface of your thigh, with the linea aspera touching your pants. The head of the femur should face medially towards the body.

20 TIBIA Medial malleolus Medial condyle Lateral condyle Fibular notch Tibial tuberosity

21 TIBIA Medial malleolus

22 TIBIA Medial malleolus Fibular notch

23 TIBIA Medial malleolus Fibular notch

24 TIBIA Lateral condyle Medial condyleTibial tuberosity

25 Intercondylar eminance TIBIA

26 How to tell right and left tibia? Place the tibia on the anterior surface of your leg with the tibial tuberosity facing anteriorly (not touching your leg). What side is the medial malleolus on? It should be medial, towards the midline of the body.

27 FIBULA Lateral malleolus Head Lateral malleolus Head

28 How to tell R from L fibula Place the fibula on the table with the smooth side of the lateral malleolus facing down. Pretend to trace the malleolus. Notice that one side (posterior) is straight and the other side (anterior) is curved. Place the smooth surface of the lateral malleolus against your sock at your own lateral malleolus. The curved edge should face anteriorly, not posteriorly.

29 TALUS TARSALS CALCANEUS NAVICULAR CUBOID INTERMEDIATE (or 2 nd ) CUNEIFORM MEDIAL (or 1 st ) CUNEIFORM LATERAL (or 3 rd ) CUNEIFORM

30 Calcaneal tuberosity CALCANEUS Lateral facet of talus Medial facet of talus

31 The facets are the smooth surface on the sides of the talus Medial facet of talus Lateral facet of talus

33 FIRST METATARSAL METATARSALS: 1-5 FIFTH METATARSAL Styloid Process

34 PROXIMAL PHALANX, FIRST DIGIT PHALANGES DISTAL PHALANX, FIFTH DIGIT INTERMEDIATE PHALANX, THIRD DIGIT DISTAL PHALANX, FIRST DIGIT

35 Patella (pat Ella, don’t PET Ella) Apex Base Lateral articular facet (concave) Medial articular facet (convex) Medial border Lateral border

36 Patella Lateral articular facet Medial articular facet The Lateral facet is larger. If you place the patella on your desk, it will always fall onto the lateral articular facet.

37 Turning An Ankle Into A 'Knee' Patient was a five-year-old girl with Ewing's sarcoma, a cancerous tumor, behind her left knee. Surgeons at The Children's Hospital of Philadelphia used a limb-sparing technique called rotationplasty to remove the diseased portion of bone, turn the shortened portion of the leg bone in a half-circle and reattach it, with the ankle joint functioning as a knee. With a prosthetic attached to the mobile joint, the child, now 13, enjoys gymnastics and cheerleading.
