Introduction
|
|---|
Complex fracture-dislocations of the elbow can often be either irreducible
or unstable, with an inability to hold the reduction or with the delayed
development of subluxation or dislocation. The aim of the present study was to
evaluate the etiology of the instability, both osseous and ligamentous, and
the results of stabilization with a combination of internal fixation, ligament
repair, radial head arthroplasty and, when necessary, hinged external
fixation. Figures 1 and
2 represent our formulated
protocol and treatment algorithm for elbow fracture-dislocation in this series
of thirty-two patients.
