100

The CR is centered here for an AP foot.

What is the base of the 3rd MT?

100

This exam should include both the ankle and knee joint.

What is Tib/Fib?

100

An oblique foot has this direction and degree of rotation.

What is medial & 30-40°?

100

On this projection of the foot, there is no overlap between the 1st and 2nd MT bases.

What is AP (dorsoplantar)?

100

What surface of the foot is perpendicular to the IR for a plantodorsal axial calcaneus projection?

What is plantar?

200

The CR is centered here for a lateral ankle.

What is the medial malleolus?

200

This exam should include the distal femur and proximal tib/fib.

What is knee?

200

The ankle requires this degree of rotation to fully open the mortise joint.

What is 15-20° medial?

200

The fibula is visualized this way on a lateral ankle.

What is superimposed over the posterior tibia?

200

The reason the proximal and distal joint spaces may appear closed on a tib/fib.

What is the divergence of the beam?

300

The CR is centered here for a lateral toe (2nd-5th).

What is the PIP joint?

300

This position demonstrates the mortise joint fully open.

What is 15-20° oblique ankle?

300

Patients with a high foot arch use this CR angle for an AP axial.

What is 15° cephalad?

300

The femoral epicondyles are visualized this way on a lateral knee.

What is superimposed?

300

The positioning error for this lateromedial knee.


What is over-flexed?

400

The CR is centered here for an AP knee.

What is 1.25cm inferior to the patellar apex?

400

This position demonstrates the sustentaculum tali and the base of the 5th MT.

What is the plantodorsal axial calcaneus?

400

The lower leg is positioned this way for an AP knee.

What is extended and internally rotated 3-5°?

400

This tarsal bone is visualized inferiorly/posteriorly on a lateral foot.

What is the cuboid?

400

For an AP ankle the intermalleolar line sits at what angle to the IR.

What is 15-20°

500

The CR is centered here for the PA axial intercondylar fossa.

What is the mid-popliteal crease?

500

This position demonstrates the lateral epicondyle of the femur and tibia in profile.

What is medial knee oblique?

500

The lateral patella position requires this amount of knee flexion.

What is 5-10°?

500

When a lateral knee is over rotated the adductor tubercle is found here.

What is anteriorly?

500

The fat pad that is only visible on a properly positioned lateral ankle.


What is anterior pretalar fat pad?
