Forty-seven children with 32 open tibial fractures, 11 open femoral fr
actures, and six closed tibial fractures with compartment syndrome, wh
ich were surgically opened, were assessed for the time to union and in
cidence of nonunion and infection. Treatment varied with fracture seve
rity and patient age. Tibial external fixators were supplemented by sh
ort-leg casts, and fixators were removed at an average of 7 weeks. No
child required further surgery to achieve union. There was one (2%) de
layed union and no nonunions. Three fractures (6%) developed infection
s. No pin-tract infections occurred in tibial fractures treated with e
xternal fixation with casting. The relation between age and time to un
ion was statistically significant. In open fractures without segmental
bone loss or soft-tissue loss requiring major reconstruction, bony he
aling can be expected within 6 months.
