Osteosynthesis of pediatric femoral shaft fractures with flexible intramedullary nailing-experience from developing world.

BACKGROUND

Flexible intramedullary nailing (FIN) has become the standard treatment for pediatric femoral fractures in the 6-14 years age group. The other treatment options include traction plus spica casting and external fixation. In spite of excellent results described, there is disunity in the orthopedic fraternity regarding its usefulness and nail material. The aim of our study is to determine the outcome of pediatric femur fractures treated with Stainless steel FIN.

METHODOLOGY: Between 2014 to 2018, 45 children within the age group of 6-12 years with femoral shaft fractures were included in the study. Two Stainless steel nails of predetermined size were inserted in a retrograde fashion under fluoroscopy. Patients were followed up at regular intervals to assess clinical and radiological parameters. Final results were evaluated using Flynn's clinical criteria.

RESULTS

There were 29 boys and 16 girls with an average age of 10.2 years. Fracture patterns included transverse (n=8), oblique (n=20), spiral (n=12) and comminuted (n=5). Open injuries were present in two cases and five patients had associated injuries. The mean injury to surgery interval was 2.9 days, mean hospital stay was 4.8 days and mean time to union was nine weeks. Complications included deep infection with delayed union in one case, superficial infection in two cases, malunion in three cases, limb length discrepancy of >10 mm in one patient and skin irritation from prominent nail tips in five patients. Results were excellent in 36 patients, satisfactory in eight patients and poor in one patient.

CONCLUSION

FIN is safe, reliable and efficacious method of fixation because of its simplicity, minimal invasiveness, ease of insertion and removal with better cosmesis, rapid union with short rehabilitation, less psychosocial stress to the patient and family.
