Abstract
Concomitant ipsilateral femoral and tibial fractures result from high velocity injuries and are often associated with other, life threatening, injuries. They are rare injuries in children with few published series, none of which comment on the use of flexible intramedullary nails in the treatment of such injuries.
We present our experience of concomitant ipsilateral femoral and tibial fractures in children and discuss the use of flexible intramedullary nails in their management.
Hospital records and radiographs of 19 such injuries in 18 patients were studied. These cases were divided into three groups based on the method of treatment. Group A: (8 cases) both the femoral and tibial fractures were internally fixed.
Group B: (4 cases) only one out of the two fractures had internal fixation while the other was externally immobilised.
Group C: (7 cases) both femoral and tibial fractures were treated with external immobilisation like external fixators, plaster cast or traction.
Six cases in group A were treated with flexible intra-medullary nailing The mean age was 8.5 years. The average follow up was 3.5 years. All patients were reviewed and assessed clinically following discharge from hospital.
Patients treated with internal fixation of both fractures had a shorter hospital stay and were able to weight bear earlier. Limb length discrepancy was common in conservatively treated patients. Mean limb length discrepancy was 3.8 cm of shortening. A better range of knee movement was observed in patients treated with flexible nail for femoral and tibial fracture. Over all a good result was achieved in 70% of the patients. Using our assessment criteria we found that Group A faired better than the other two groups on all accounts.
Only a few small series of such a rare injury has been mention in the literature. More complications have been reported in children under 10 years of age. In our study we found better results when both tibial and femoral fractures were treated with internal fixation. The out come results in our patients were not related to age.
We found that internal fixation with closed flexible intramedullary nailing of both femoral and tibial fractures was a safe and effective technique and has therefore been recommended.
