[Animation (2-3 seconds): Brief "wowee" animation of tibia(blue bones effect), twisting, turning, zooming into view. (Note: LO is to graphically capture/focus student's attention and excite them vs. to each anatomy.) Last image of animation shows three areas of tibia highlighted in different colors. Label proximal end, diaphysis, distal end.]

Everyone has bruised their shin before, but major damage is hard to do. That is because the tibia, the bone that we often call our "shin bone" is a large, thick, and long bone . The tibia bears the weight of everything above it and is a crucial component of the knee.

Like the femur, the tibia is described as having a proximal end or head, the middle portion or shaft (diaphysis), and a distal portion. By studying these three areas of the tibia,you’ll learn about the locations and the functions the femur’s primary anatomical features.

By the end of this unit, you should be able to:

- Locate the features and markings of the tibia on its anterior, medial, lateral, and posterior aspects.

- Describe the functions of the features and markings of the tibia.

- Identify the features and markings of the tibia on a plain film x-ray.

Bones/Tibia/Proximal End Features

Consider the proximal end of the right tibia. As you learned in the previous unit, the tibia articulates with the femoral condyles. This articulation occurs at the proximal epiphysis of the tibia.

Locate and identify the two concave plateaus of the tibia that articulate with the femoral condyles. These features are the medial condyle of tibial plateau and lateral condyle of tibial plateau. (Click on the features to identify them.)

[Graphic: Explore the anatomy button]

The double ridge-like structure and the bony valley between the condyles is the intercondylar eminence; it is a site for ligament attachment. Locate and identify the intercondylar eminence.

Change to

IAA relating to head: begin with full view of femur and semi-transparent coxal bone (so you can see through to bone features); zoom in and rotate; then make coxal disappear and rotate (as you already have). Color for coxal bone transparency should match text color for "coxal bone".

IAA relating to condyles: same as above, only with femur as semi-transparent.

IAA for intercondylar eminence: same as above only with related ligaments.

structure names in text match structure colors in IAAs (color choice above is just a sample; Dave to determine actual structure colors)

When students click on structure's IAAs, specific structure name appears in text field.

Bones/Tibia/Shaft Features

Continue your study of the tibia (right) by examining the features of the diaphysis (shaft). Note that the shaft is bowed anteriorly, altering the position of certain structures as one moves up and down this middle region of the tibia.

The tibial tuberosity is a roughened prominence on the tibia for the attachment of the patellar ligament. Locate and identify the tibial tuberosity.[Graphic: Explore the anatomy button]

A ridge running the length of the anterior diaphysis is called the anterior border. Run your hand along the front of your lower leg and feel the bony anterior border. Now locate and identify the anterior border.

[Graphic: Explore the anatomy button]

A stabilizing membrane runs along the lateral margin of the diaphysis and attaches a to bony ridge. This ridge is called the interosseus border. Locate and identify the interosseus border.[Graphic: Explore the anatomy button]

Bones/Tibia/Distal End Features

Now, consider the distal end of the right tibia. The predominant structure at the distal end of the tibia is the medial malleolus. This medial projection can be felt as a prominent bump on the inside of your ankle. Its anatomical function is...Locate and identify the medial malleolus.

Bones/Tibia/Xray Application

Damage to a bone can usually be seen by taking a radiographic image called an x-ray. A radiologist must be able to identify all parts of a healthy bone in order to determine if anything is damaged.

First, identify and name the different structures of the femur seen on these x-rays.

[Graphics: Two x-rays (labeled lateral view and medial view) of a tibia with ABCDEF's and arrows for all tibia features/structures listed below. One feature/structure is obviously damaged.]

lateral condyle of tibial plateau (abcde with buttons)

tibial tuberosity (abcde with buttons)

anterior border (abcde with buttons)

interosseus border (abcde with buttons)

medial malleolus (abcde with buttons)

In examining the structures, you'll note that one of the structures is damaged. Can you determine which of the above structures it is? (abcde with buttons)

Once you have entered all your responses, view the correctly labeled xray.

[Graphic: same as above only with labels.]

You have reached the end of the femur unit. Continue your learning by studying the tibia.
