Thirtyfive cases of diaphyseal fractures of tibia with delayed union and nonunion were treated by pulsing electromagnetic field (P.E.M.F.). In 18 cases bone grafting was also done. Average duration of stimulation was 10 hours a day for 16 weeks. Average time taken for union was 14 weeks in cases without bone grafting and 13 weeks in cases with bone grafting. Four patients had failure of union mainly because of non-cooperation of patient. Twentytwo cases were having infected or open fractures out of which 19 united.
