ABSTRACT

Objective To explore the causes and management of delayed un ion and non-union of long bone fracture of the leg. Methods 13 cases of delayed union and non-union of long bone fracture of the leg were treated with interlo cking intramedullary nails. 2 cases were given close implanting, and 11 cases we re managed with open reduction, of whom 9 were also grafted with autogenous bone . All patients were given early static interlocking, and 4 cases were given late dynamic interlocking. Results X-rays and follow-up showed that all patients h ealed up after an average of 14.5 months.Conclusions Interlocking intramedullary nails are a satisfactory method to treat delayed union and non-union of long b one fracture of the leg. The key points of the operation are reaming, selecting suitable nails and dynamic interlocking when necessary.
