• The anterior interosseous nerve is a
motor branch off the median nerve
that runs along the interosseous
membrane, passing between the
flexor digitorum profundus and flexor
pol licis longus on its way to the
pronator quadratus. Occasionally this
nerve is compressed by the forearm
muscles or overlying fibrous bands,
secondary to forceful muscle
contractions. Anterior interosseous
nerve compression causes pain and
motor weak ness in the proximal
forearm. The prevailing sign is loss of
pinch strength between the tips of
the thumb and index finger.
•
Radial nerve compression, or radial
tunnel syndrome, can occur within the
radial tunnel, which extends anteriorly
from the radial head to the supinator
muscle. Radial tunnel syndrome is
typically caused by repetitive or
vigorous wrist extension and forearm
pronation and supination. It is often
incorrectly identified as lateral
epicondylitis but careful examination
can differentiate the two conditions.
With radial tunnel syndrome,
tenderness is present several
centimeters distal to the lateral
epicondyle, within the supinator–
extensor muscle mass of the proximal
forearm

The milking maneuver. The patient
grabs the thumb on the arm with the
affected elbow by passing the other
hand beneath the affected elbow. This
locks the shoulder, thereby reducing the
effect of shoulder rotation and motion,
which may confuse the examination.
The examiner palpates the medial joint
as the patient pulls on the thumb,
exerting a valgus force on the elbow.
Note that the elbow is in a high degree
of flexion, greater than the angle at
which a person throws; it also is flexed
to the point that bony anatomy
contributes to valgus stability of the
elbow.

Coronoid process fracture
with hemarthrosis. The
posterior fat pad (arrows) is
shown clearly on this lateral
view with the arm flexed to
90°, indicating joint effusion.
The anterior fat pad (open
arrow) is clearly visible. There
is a fracture of the coronoid
process (curved arrow) and a
loose body (arrowhead)
Cubital tunnel. The ulnar
nerve (asterisk) lies in a
tunnel bridged by the
arcuate ligament (dashed
line), which extends from
the medial epicondyle to
the olecranon process. LAT
