We reviewed the cases of fifteen children who were treated for a
Monteggia injury. Transverse and metaphyseal fractures of the ulna were
stable after closed reduction, but oblique fractures of the shaft
redisplaced and required intramedullary pinning. Five patients who were
seen late had open reduction and internal fixation of the fracture. Four of
these children had reconstruction or repair of the annular ligament, with
excellent results. But in the child in whom the ligament was not repaired
the radius subluxated.
