What is another name for the anterior crest?
The shin bone
What is the name of the flat triangular bone about 2 inches in diameter
A Patella
Where does the greater trochanter lie on the femur?
The lateral aspect
Why do we rotate the leg 5 degrees internally for the distal femur?
To ensure we have a true AP
How many bones make up the tarsals?
7
What is the name for the bump at the lateral end of the fibula?
Lateral Mallelous
How many degrees do we flex the leg for the lateral patella?

The medial aspect
What is another name for AP Frog leg projection?
Modified Cleaves Method
What structures make up the ankle joint?
The tibia, fibula and the talus
Which bone in the lower leg is weight bearing?
The tibia
What happens when you flex the knee?
The patella becomes more pulled into the intercondylar sulcus
How do we ensure the hip joint is included on an AP and Lateral proximal femur?
The top of the IR should be at the level of the ASIS
What structures make up the ischium?
Ramus, body, ischial tuberosity, ischial spine, lesser sciatic notch
Why is the CR angled for AP toes?
To open the joint spaces; to make the CR perpendicular to the phalanges
What is the name of the disease that causes the tibial tuberosity to separate from the body of the tibia in young people?

How can you distinguish between the medial and lateral condyles?
The adductor tubercle, which is a slightly raised area that receives the tendon of the adductor tubercle
How do you determine over rotation on a lateral knee?
By looking a the end of the fibula; there will be less superimposition of the head of the fibula by the tibia
How do you know you have a true lateral projection of the proximal femur?
The greater trochanter is superimposed over the neck of the femur
What is the purpose of the Taylor Method? (Outlet projection AP Axial)
To demonstrate the inferior and superior ramus and ischium
