PROXIMAL FOREARM

AP projection of the radial head

Holly described a method of obtaining the

distal humerus

for AP PROJECTION (PARTIAL FLEXION) The patient is positioned as described for the

30 degrees from horizontal

The forearm should be supinated enough to place the horizontal plane of the wrist at an angle of

• Hand supinated

• Dorsal surface of forearm against IR

• Elbow partially flexed

PROXIMAL FOREARM AP PROJECTION (PARTIAL FLEXION) Part Position:

Proximal forearm is shown when elbow cannot be fully extended

structure of proximal forearm

PROXIMAL FOREARM AP PROJECTION (PARTIAL FLEXION) Structure Shown

• Center the flexed elbow joint to the center of the IR.

• The long axis of the superimposed forearm and arm should be parallel with the long axis of the IR

• Move the IR toward the shoulder so that the central ray passes to the midpoint.

PROXIMAL FOREARM PA PROJECTION (ACUTE FLEXION) Part Position:

Perpendicular to the flexed forearm, entering approximately 2 inches (5 cm) distal to the olecranon process

PROXIMAL FOREARM PA PROJECTION (ACUTE FLEXION) Central Ray

• The superimposed bones of the arm and forearm are outlined

• The elbow joint should be more open than for projections of the distal humerus
