Where should the top of the image receptor be placed for an AP projection of the pelvis?
The image receptor must be placed parallel to the femoral neck for the axiolateral (inferosuperior) projection of the hip. The posterior oblique (Judet method) for the acetabulum requires a 10° to 15° rotation of the body. A radiograph of an AP pelvis reveals that the lesser trochanters are not visualized.

Demonstrate possible joint separations or ligament tear. Which projection of the ankle will open up the distal tibiofibular joint? AP Oblique with 45 degree rotation.
What type of joint is distal tibiofibular?
Articulating Surfaces. The distal (inferior) tibiofibular joint consists of an articulation between the fibular notch of the distal tibia and the fibula. It is an example of a fibrous joint, where the joint surfaces are by bound by tough, fibrous tissue.

Which projection should be performed and evaluated prior to performing a Settegast projection for trauma?
Terms in this set (50) Which projection should be performed and evaluated prior to performing a Settegast projection for trauma? The answer is B. A tangential projection of the patella for trauma should not be performed until a transverse fracture has been ruled out with a lateral projection.
Which of the following projections of the ankle would best demonstrate the mortise?
To best demonstrate the distal tibiofibular articulation, a 45° medial oblique projection of the ankle is required. The 15° medial oblique is used to demonstrate the ankle mortise (joint).
What type of joint is the ankle mortise?
hinge type joint
In which position is the ankle joint most stable?
dorsiflexion
What does ankle mortise mean?
The ankle joint is made up of two joints: the true ankle joint, which moves the foot up and down, and the subtalar joint, which moves the foot from side to side. The ankle mortise is the “hinge” that connects the ends of the tibia and fibula to the talus.
Is the ankle a Condyloid joint?
A hinge joint: found at the elbow and knee. The range of movement is limited to one plane just like a door hinge. A condyloid joint: found at the wrist and ankle. Two bones have a small range of movement limited by connecting ligaments.
Is ankle a ball and socket joint?
The ball-and-socket ankle joint is a malformation of the ankle in which the articular surface of the talus is hemispherical in both the anteroposterior and lateral projections and has a congruent, concave tibial articular surface.
What are 6 types of synovial joints?
There are six types of freely movable diarthrosis (synovial) joints:
- Ball and socket joint. Permitting movement in all directions, the ball and socket joint features the rounded head of one bone sitting in the cup of another bone.
- Hinge joint.
- Condyloid joint.
- Pivot joint.
- Gliding joint.
- Saddle joint.
What is one example of a saddle joint?
The prime example of a saddle joint is the trapeziometacarpal joint at the base of your thumb. It connects the trapezium and the metacarpal bone of your thumb.
What sports use the saddle joint?
The joint is shaped like a saddle with the other bone resting on it like a rider on a horse. Movement occurs backwards and forwards and from side to side, such as at the base of the thumb. You would use a saddle joint when gripping a racket in tennis or squash.
What movement does a gliding joint allow?
Gliding joints: only allow sliding movement. Hinge joints: allow flexion and extension in one plane. Pivot joints: allow bone rotation about another bone. Condyloid joints: perform flexion, extension, abduction, and adduction movements.
What joints can perform Circumduction?
Circumduction is the movement of the limb, hand, or fingers in a circular pattern, using the sequential combination of flexion, adduction, extension, and abduction motions. Adduction, abduction, and circumduction take place at the shoulder, hip, wrist, metacarpophalangeal, and metatarsophalangeal joints.
