[Pseudarthrosis of the olecranon].

Non union of the olecranon is rare, resulting from inadequate or failed primary internal fixation, or from extension immobilization. Olecranon non unions can generally be handled by open reduction and strong internal fixation with or without application of a bone graft. We also observed radiographic evidence of non union in several patients with full range of motion and no pain. In these cases the non union slowly but spontaneously healed.
