The role of bone scan in the diagnosis of carpal fracture in children.

A retrospective study was performed to evaluate the role of bone scan in the management of wrist trauma in children with equivocal radiographic findings. Thirty-one out of the 50 children showed no fracture. Six of them were treated for a median period of 9 days on clinical grounds; the others were discharged with reassurance. Four patients with evidence of soft tissue injury received no further treatment. Six of the 12 patients with a fracture on bone scan were treated with a cast for more than 4 weeks. None of the patients developed any complications. Bone scan is helpful when the diagnosis of a carpal fracture in children is equivocal.
