Body Movements Flashcards
Abduct
Away from the midline or midsagittal plane
When positioning for an AP elbow, abduct the arm and place the elbow on the image receptor in an AP position.
Adduct
Towards the midline or midsagittal plane
When positioning for a lateral scapula, adduct the forearm and place the forearm 90 degrees to the humerus
Circumduct
To move any limb in a circular pattern allowing the distal end to freely form a circle
when arthrography of the shoulder is done, the patient must circumduct the joint in order to mix the contrast media and air
Extend
Straighten the joint, thereby increasing the angle to 180 degrees or more between the proximal and distal components of the joint. To extend the arm is to straighten it. If we refer to the extension of the spine, the patient would bend backward from the waist
When imaging the AP knee, the joint must be fully extended so that the femur and tibia are straight at 180 degrees
External (Rotation)
Anterior surface faces laterally or towards the side
When imaging the radial head, the elbow must be externally rotated
Evert
Turn away from midline
When imaging the medical oblique foot, the foot must be everted
Flex
To close a joint thereby decreasing the angle of the joint to less than 180 degrees
When imaging a lateral elbow, the patient’s elbow joint must be flexed 90 degrees
Internal (Rotation)
The anterior surface faces medially or towards the midline
When imaging the medial oblique ankle, the ankle must be rotated medially
Invert
Go towards midline as in the plantar surface of the foot. The foot is inverted
When imaging the 5th metatarsal, the foot is inverted
Pronate
Turn a body part so that its anterior surface faces posteriorly
When imaging a PA wrist, the patient’s forearm is pronated
Supinate
To turn a body part so that its posterior surface faces posteriorly or so that the anterior surface faces anteriorly
When imaging an AP forearm, the forearm must be supinated
