Displaced fractures of the proximal humerus in children require open/closed reduction and internal fixation.

Fractures of the proximal humerus in children are rare and constitute only 3% of all epiphyseal injuries. From 1992 to 2002 sixteen patients aged 4 - 15 years with a displaced fracture of the proximal humerus were treated at our level I trauma unit. The mean follow-up of the patients was 23.8 months (8 - 72). Ten children had a metaphyseal fracture and six a Salter and Harris Type II injury. Only one metaphyseal fracture was treated conservatively; the other patients underwent surgery (ORIF [= open reduction internal fixation] in ten patients, CRIF [= closed reduction internal fixation] in five patients). Follow-up examination showed no shortening or major angulation of the humerus in any of the sixteen cases. Fifteen children showed excellent and good results. There was only one average result in a polytraumatized child with additional injuries in both upper extremities. Based on the results of this study we suggest performing ORIF/CRIF in displaced fractures of the proximal humerus in children.
