What is meant by a 'simple' versus a 'complex' dislocation?
A simple dislocation is one in which there is no associated fracture. Complex dislocations are really fracture-dislocations, and have markedly different management and prognosis.
What are the most common associated fractures (not present in this case)?
Radial head / neck fractures and coronoid process fractures are most common, although many other fractures are sometimes encountered.
How should this patient be managed?
When elbow dislocation is simple (i.e no associated fracture) closed reduction and a brief period (e.g. <2 weeks) of immobilisation at 90 degrees of flexion usually suffices.
What term is used when both coronoid process and radial head fractures are present in the setting of a posterior dislocation? Why?
Terrible triad of the elbow. It is so-called because of the difficulties encountered during management, and the often poor outcome.
X-rays demonstrate a posterior dislocation of the elbow without evidence of an associated fractures.
