Is Legacy Technique of Anatomically Bowed Ante Grade Intramedullary Device Fixed at Metaphysis Cancellous Bones & Single Proximal Screw Locking Suffice for Good Outcome in Femoral Fractures?
Introduction: Intramedullary device considered as a load sharing device is one of the commonest surgeries now a days. From the era of straight nails, flexible nails to anatomically curved nails have been used to fix the fractures of the femur. It provides biological environment to the fracture being a potentially closed reduction method. Objective: To measure the outcome of the method of femur fixation by anatomically curved interlocking nail & proximal single locking with two distal locking. Material & Methods: We have studied the (n=37) patients retrospectively. All the fractures treated with femur interlocking nail & proximal single (preferentially dynamic) locking .95% was males & 5% were females in our study. Mean age was 28 years. Fractures were classified by AO classification preoperatively. Results: Mean union time was 22 weeks. (n=34)92 % of patients had excellent outcome & (n=3) 8% had poor outcome. 91.80 % of patients had no limb length discrepancy.70.27% patients of excellent outcome had high velocity trauma & 75% were operated within ten days of trauma incidence. Injury & surgery interval has no effect on the results. Conclusion: Out of different methods of fixation our studied method was anatomically curved femur interlocking nail for treatment of femoral shaft fractures achieves good functional outcome. The single proximal screw allows shorter surgery time, prevents added stress risers at the base of neck & possibly primary dynamicity & callous micro motion. These devices can achieve good anatomical alignment & reduces the future chances of knee arthritis.
