Upper Extremities Finger - Shoulder
| Question | Answer |
|---|---|
| How many bones does a hand have? | The 27 bones on each hand and wrist are divided into the following three groups: Total 27 Phalanges (fingers and thumb) 14 Metacarpals (palm) 5 Carpals (wrist) 8 |
| Name the proximal row of carpals: | (1) Scaphoid (2) Lunate (3) Triquetrum (4) Pisiform |
| Name the distal row of the carpals: | (1) Trapezium (2) Trapezoid (3) Capitate (4) Hamate |
| A good criterion by which to evaluate a true lateral position of the elbow when it is flexed 90° is the appearance of the three concentric arcs. What are they? | 1 & smallest arc is the trochlear sulcus. 2nd & intermediate arc appears double-lined as the outer ridges or rounded edges of the capitulum and trochlea. The trochlear notch of the ulna appears as a 3rd arc of a true lateral elbow. |
| Ulnar deviation - why is it used? | The ulnar deviation movement of the wrist “opens up” and best demonstrates the carpals on the opposite side (the radial or lateral side) of the wrist— the scaphoid, trapezium, and trapezoid. Because the scaphoid is the most frequently fx carpal bone... |
| Radial deviation - why is it used? | A less frequent PA wrist projection involves the radial deviation movement that opens and best demonstrates the carpals on the opposite, or ulnar, side of the wrist—the hamate, pisiform, triquetrum, and lunate. |
| AP projections of the elbow a lateral rotation: | separates the radius and ulna |
| AP projections of the elbow a medial rotation | superimposes the radius and ulna |
