Colles and Metacarpal Fracture
Fracture of distal radius (in case, also metacarpal), ulnar styloid, and dorsally displaced causing a dinner-fork deformity. If it is volarly displaced, it is a Smith’s fracture.
Bennetts Fracture
Fracture of first metacarpal. Notice that the fracture is intra-articular.
Bankart Lesion
Fractured humeral head and torn articular cartilage.
Avulsion Fracture
Avulsion fracture of the base of 5th metatarsal.
Anterior Dislocation of Humerus
Anterior dislocation of the humerus (left) and normal (right) for comparison.
Tibial Plateau Fracture
Lateral view and AP view.
Talus Fracture
Chip fracture from talus. Note the small triangular fleck of bone lifted from the superior surface of the neck of the talus just proximal to the talo-navicular joint. This is commonly seen as a small fragment of bone with cortex all around or as a small projecting exostosis. In either case, it probably represents the appearance of an old fracture in this region.
The present film represents the appearance of the recent fracture which is not very often seen. It is probably due to pull of ligaments around the talo-navicular joint.
