Anterior glenohumeral (shoulder) dislocation. How
do we know it is anterior?
12

Anterior glenohumeral (shoulder) dislocation. The
fact that we see the humeral head in profile
tells us it is externally rotated (it would be
internally rotated if the patient was dislocated
posteriorly.)
An internally rotated humeral head looks like a
light bulb.

We can also obtain an axillary view and see
that the humeral head is anterior to the glenoid.

Proximal ulna fracture With fracture subluxation
of radial head This combination of injuries is
known as a Monteggia fracture.

Elbow fracture dislocation Fracture of the
olecranon with anterior dislocation of radius and
ulna. Air in soft tissues indicates that it is an
open fracture.

Distal radial buckle or torus fracture. The
bone has crumpled rather than broken.

Pathology?
51

Scapholunate dissociation The scapholunate
ligaments are torn allowing separation of the two
bones like a gap between the front teeth (Terry
Thomas or Lettermans sign). The spacing
between all of the carpal bones should be the
same.
