Convergent and divergent dislocation of the pediatric elbow: two case reports and comprehensive review of literature

Abstract

Convergent and divergent pediatric elbow dislocations are rare injuries. When properly diagnosed and treated without delay, both types of dislocations have a good prognosis. We describe a case of convergent elbow dislocation in a 16-year-old boy. The patient underwent operative intervention and demonstrated full range of motion at the 4-year follow-up. Our second case describes an 11-year-old boy with a divergent elbow dislocation associated with an ipsilateral distal radius fracture and distal radioulnar joint dislocation. The patient showed full range of motion 1 year after closed reduction and casting and had no residual deformities or abnormalties.
