Chapter 7 Flashcards
The second largest bone in the body is the
Tibia
The name of the small round bones located on the planter surface of the foot typically beneath the first MTP joint is the
Sesamoids
How many degrees are the lower leg and foot rotated for the AP oblique projection of the toes in medial rotation
30 to 45
The central rate ululation for an AP oblique projection of the toes is
0°
To better demonstrate the TMT joint spaces of the foot of posterior angulation of how many degrees is required
10
The most commonly performed oblique projection of the foot is the ___ oblique in ___
AP medial rotation
For an AP oblique projection of the foot and either medial or lateral rotation, the plantar surface of the foot for an angle of
30°
For improved demonstration of the interphalangeal, metatarsalphalangeal, and tarsometatarsal joints which projection should be performed
AP axial foot
Equal amounts of space between the second through fourth metatarsal demonstrates
No rotation on the foot
Which projection best demonstrates the tuberosity of the fifth metatarsal
AP oblique with medial rotation
Which lateral projection of the foot is the most commonly performed
Medioateral
Which projections of the foot will best demonstrate the structural status of the longitudinal arch?
Lateral (lateromedial) weight-bearing
What is the central right angulation for the axial (plantodorsal) projection of the calcaneus?
40°
For an axial projection of the calcaneus, the ankle should be dorsiflexed so the planter surface of the foot is
90° from the plane of the IR
Which of the following is not clearly demonstrated on an AP projection of the ankle
Ankle Martise
To prevent lateral rotation, how should the foot be positioned for the lateral projection of the ankle?
In dorsiflexed
For the lateral projection of the angle, the central ray must enter the
Medial malleolus
Where will the fibula be located on a properly position lateral radiograph of the ankle?
Over the posterior half of the tibia
To demonstrate the ankle, Mortis the leg and foot should be rotated immediately. How many degrees?
15 to 20
The medial and lateral oblique projections of the ankle, require the leg and foot to be rotated. How many degrees?
45
Which ankle projection will clearly demonstrate the ankle mortise in profile
AP oblique 15 to 20° internal rotation
Which projection will clearly demonstrate the joint spaces between the talus and both malleoli
AP oblique 15 to 20° internal rotation
Which projection of the ankle are performed on a patient following an inversion or eversion injury
AP stress studies
The talus articulates with how many bones
Four
