Introduction: Traumatic dislocations of the radial head in children as an isolated injury
are rare. The most common type is the anterior dislocation and often the mechanism
is an injury in pronation and extension of the elbow. Material: The authors report a
case of isolated anterior dislocation of the radial head in an 8 years old girl following
an injury of the right elbow. The clinical examination revealed limitation of pronosupination
motions, without overflowing deformation. The radiological study showed
anterior dislocation of the radial head, without bone lesions associated. Methods: The
child underwent manipulation under sedation, as a matter of urgency, with closed
reduction, review of joint stability and immobilization in a plaster cast with the elbow
at 90º and supination of the forearm, for 3 weeks.The authors reviewed the literature
of this pathology and discussed the therapeutic options for its resolution. Results:
After 8 months of follow-up the clinical and functional outcome was satisfactory, with
no significant differences between the injured and normal elbows. Discussion and
Conclusion: The diagnosis is easily missed and is established on the basis of a
correct imaging procedure. Isolated dislocation of the radial head can be treated
conservatively when diagnosed in the first 3 weeks, with good functional results. After
this period, open reduction is often necessary.Thus, the reduction of the radial head
is currently recommended as soon as possible to avoid future complications, growth
deformities and joint stiffness.
