Absolute stability is desirable for articular fractures. However, this may not be possible in multifragmentary fractures of the proximal ulna. Every effort should still be directed at anatomical reduction and absolutely stable fixation of the major articular surface fragments, particularly the coronoid process. In this situation, the fracture must be bridged without compression to preserve size and shape of the olecranon fossa. Small interfragmentary screws, K-wires, medial, or lateral miniplate may improve stability.
Olecranon fractures comprise around 10% of all fractures around the elbow. They have a bimodal distribution and usually occur as high energy injuries in the young, and low energy falls in the elderly.
These can occur as a direct blow, resulting in comminuted fractures, or indirectly, as a fall onto an outstretched hand, resulting in transverse or oblique fractures.
The position of the elbow can influence the pattern of injury. Radial head and coronoid fractures have been shown to occur in laboratory testing at flexion of less than 80 degrees, olecranon fractures at 90 degrees of flexion and distal humeral fractures at greater than 110 degrees.
Anatomically it is worth remembering that the olecranon, with the coronoid process, form the greater sigmoid notch and form the ulno-humeral articulation that acts as a primary stabilisers of the elbow (along with the medial and lateral collateral ligament). The olecranon receives the insertion of the triceps, as well as the anconeus on the lateral side.
