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.

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.

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.

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.

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.
