Initial fixation with locked intramedullary nailing for the treatment of bilateral femoral shaft fracture

[Objective]To investigate the efficacy and the application value of interlocked intramedullary nailing(IIN) for bilateral femoral shaft fracture(FSF).[Method]Twenty-one cases of bilateral FSF were treated by IIN between March 1998 and March 2005.Their average age was 39.6(ranged 29～48).Thirty-five limbs of them were closed fractures,and 7 limbs were opened.Among them,18 limbs had fractures in the upper third of the femoral shaft,11 limbs in the middle third and 13 limbs in the lower third.The continuous passive motion began averaging 5 days after operation.[Result]The average follow-up period was 11.5 months(6 to 32 months).Clinical bone healing was achieved after 15.5 weeks(10~30 weeks).NO fat embolism syndrome(FES),shortening,infection or break of nail occurred in all patients.The long term effect was evaluated according to Ma Yuanzhang's evaluation standard,90.5%(19/ 21) showed excellent function of joints and limbs.[Conclusion]IIN provides a satisfied approach to the treatment of bilateral FSF.It has the advantages of fewer invasions,less blood loss,steady fixation,short healing time,early function recovery and less complication.This kind of treatment is worth to be recommended for the bilateral FSF,prevention of FES should be emphasized on.
