Exam 4: Image Analysis of the Upper Extremity

A lateral finger projection obtained with the finger in a 45-degree PA oblique projection demonstrates 1)equal soft tissue width on both sides of the phalanges. 2)more midshaft concavity on one side of the phalanges than on the opposite side. 3)twice as much soft tissue on one side of the phalanges as on the opposite side. 4)convexity on one side of the phalanges and concavity on the opposite side.

A right lateral fourth finger projection obtained with the hand internally rotated to 20 degrees demonstrates 1)equal soft tissue width on both sides of the phalanges. 2)more phalangeal midshaft concavity on the side facing the fifth finger. 3)convexity on one side of the phalanges and concavity on the opposite side. 4)greater phalangeal midshaft concavity on the side facing the third finger.

Which of the follow statements is true as demonstrated on a lateral elbow projection?

A lateral elbow projection obtained with the wrist and hand pronated demonstrates 1)the radial head anterior to the coronoid. 2)the radial tuberosity in profile anteriorly. 3)an open elbow joint. 4)the radial tuberosity in profile posteriorly.

A tangential, inferosuperior carpal canal wrist projection with accurate positioning demonstrates

A poorly positioned PA oblique wrist projection demonstrates superimposition of the trapezoid and trapezium, and the capitate is superimposed by the trapezoid. How should the positioning setup be adjusted to obtain an optimal projection?

An internally rotated AP oblique elbow projection with accurate positioning demonstrates which of the following structures in profile? 1)Capitulum 2)Radial head 3)Medial trochlea 4)Coronoid process

A less than optimal lateral elbow projection demonstrating the capitulum posterior to the medial trochlea will
