Background: The present study was conducted for comparing the efficacy of dynamic hip screw (DHS) and proximal femoral nail (PFN) in patients undergoing treatment for intertrochanteric fractures of femur. Materials & methods: The present study included 40 cases of intertrochanteric fractures of skeletally mature adults out of which 20 each were operated upon with DHS and PFN. For both implants, the desired position of the lag screw was in the central femoral neck on the lateral view and in the central inferior femoral neck on the AP view, with the tip between 5 and 10 mm from the subchondral bone. Immediate postoperative radiographs were checked to determine if cortical congruence at the calcar region has been restored. All patients were given antibiotic and thromboembolic prophylaxis. Outcome was evaluated and compared. All the results were analyzed by SPSS software. Results: Mean age of the patients of the DHS group and PFN group was 61.25 and 63.88 years respectively. Non-significant results were obtained while comparing the radiological callus formation after 10 weeks and 14 weeks respectively. Significant results were obtained while comparing the mean time of early mobilization till weight bearing in between DHS group and PFN group (P- value < 0.05). Mean toe touch weight bearing in the DHS and the PFN group were found to be 48.1 and 33.8 respectively. Significant results were obtained while comparing the toe touch weight bearing in between the DHS group and the PFN group (P- value < 0.05). Conclusion: Proximal Femoral nail gives better results in intertrochanteric fractures. |
