These are articular fractures of one of the bones of the forearm, with the other one being intact (B1, B2) or combining articular fracture of one with an extra-articular fracture of the other (B3). Ref. Manual of Internal Fixation:

The classic procedure for the olecranon fractures is based on the tension band principle, assembled over Kirschner wires, and can be combined with a lag screw in fractures with an oblique fracture line. The Kirschner wires may either be placed intramedullarly or their distal end may be driven into the anterior cortex of the diaphysis. Their proximal end should be bent 180º and knocked into the cortex of the olecranon. For multifragmentary fractures, contoured small fragment plates can also be used.

The radial head fractures, when reconstructible, can be internally fixed with small fragment screws, with or without the support of a Kirschner wire that will have to be removed later on. The simple excision, with or without prosthetic substitution, is the best solution for the largely comminuted fractures and for the associated fractures of both bones.

The provisional fixation of the radial head with a transarti-cular wire placed through the humeral condyle (see B3.3) may be useful in some cases.
