Controversies regarding radial neck fractures in children.

Fractures of the radial neck in children are not uncommon, yet several aspects of their management remain controversial. Until a consensus is reached regarding the determination of displacement, acceptability of initial angulation, treatment, and outcome, the complication rate of these fractures will remain high. The authors recommend measuring the displacement as the angle between a line perpendicular to the articular surface of the radial head with a line down the shaft of the proximal radius. Fractures that are angulated less than 30 degrees require immobilization alone. Fractures angulated more than 30 degrees should be treated with an attempt at closed reduction. If closed reduction fails, a percutaneous reduction should be attempted before open reduction. Internal fixation should be performed using an oblique extraarticular Kirshner wire for all unstable fractures. Grading outcome based on range of motion and the presence or absence of pain is recommended. It is hoped that once the controversies surrounding these fractures are resolved, the long term results of these troublesome injuries will improve.
