Seven fractures of the apophysis of the olecranon in five children who
had mild osteogenesis imperfecta were treated with open reduction and
internal fixation followed by immobilization in a cast. All of the
fractures healed uneventfully. The patients were examined after an average
duration of follow-up of thirty months (range, twelve to sixty months); at
that time, no patient reported pain or limitation of function. In the four
elbows that had been followed for three years or more, there had been no
observable disturbance of growth.
