Abstract: Background: Distal femur fractures were considered difficult to heal and often led to a degree of disability and deformity. The incidence of malunion, nonunion and infection are relatively high in many studies. The management goal of distal femur fractures are correction of axial alignment, length and rotation, restoration of range of movements and rapid union so as to return the patient to normal function. We present here result of retrograde nailing of extra-articular (AO 33A1 to A3) fractures of the distal femur using Distal Femoral Nail (DFN).
Methods: In Between 2019 to 2021 total 15 patients who underwent open reduction and internal fixation for distal femoral fracture in K.R. hospital. There were 11 male and 4 female patients, age range from 16 years to 83 years, mean age.
43.8 years. Average length of follow-up was 17.5months (12 months to 24 months).
Results: Total 15 patients was available for follow up. Regular fracture healing was observed in 14 cases. Delayed union in 1 case. Two patient had superficial infection, and two patients had leg shorting of 0.5 and 1 cm. Axial misalignment (Varus/valgus angulations) was found in two cases (5º-10º) there were no implant failures. On the bases of HSS score to measure functional outcome, 7 cases had excellent, 6 cases had good and 1 cases had fair result. Poor results were seen in one patient.
Conclusion: Distal Femoral Nail is a reasonably good tool to treat distal femoral fracture.
