Upper limb XR classic cases I: shoulder and elbow

The surface of the humeral head (arrowheads) does not align with the line formed by the anterior rim of the glenoid fossa. There has been no visible bony fracture

22.2 Anterior shoulder dislocation: axial view


The humeral head (arrowheads) is displaced forwards out from the glenoid fossa and now lies under the corocoid process of the scapula (*). This indicates an anterior dislocation

22.3 Pathological fracture


There is a transverse fracture of the mid-shaft of the humerus. There are areas of lucency of the bone trabecular pattern and in places there is loss of cortical thickness (arrowheads). The patient had multiple myeloma

22.4 Clavicle fracture


There is a midshaft fracture of the clavicle. The distal part is pulled downwards by the weight of the arm and the proximal part is pulled up by the sternocleidomastoid muscle

22.5 Radial head fracture


The AP view (left) shows a fracture passing through the radial head into the elbow joint. There are raised fat pads (dark) seen both at the front and back of the distal humerus on the lateral image (right). In the context of trauma it indicates an intra-articular fracture even if no fracture is seen

22.6 Supracondylar fracture


Less than one-third of the capitulum lies in front of the anterior humeral line (dotted), indicating a fracture which is seen clearly on both views. There is a raised posterior fat pad (arrowhead) which is a sign of an accompanying joint effusion
