We managed thirty-five patients who had a fracture of the femoral shaft with interlocking fixation and twenty-five of thirty-five patients healed without conversion to dynamic intramedullary fixation and followed more than a year. The results of treatment of fractures of the femoral shaft with static interlocking nailing were reviewed. The average duration of follow-up was sixteen months(range, twelve to twenty-four months). Radiographic consolidation was seen in all fractures at a median of sixteen weeks(range, eight to twenty weeks).

There were no non-unions. We concluded that routine conversion of static interlocking to dynamic interlocking is not necessary in the intramedullary nailing of the femur shaft fractures.
