Abstract

Objective: To evaluate and compare the clinical and radiological outcomes of patients with stable intertrochanteric fractures treated with proximal femoral nail vs. dynamic hip screw. Methods: Sixty patients with stable intertrochanteric fractures, aged over 18 years, were randomly divided into the proximal femoral nail and dynamic hip screw groups. Dynamic hip screw with a three‐hole side‐plate and an anti‐rotation screw were used, as well as a modified ultra‐short proximal femoral nail for the smaller Asian population. The intra‐operative, early and late complications were recorded, and the functional outcome of each group was assessed using the Harris Hip Score. Results: In the dynamic hip screw group, the one‐month mean Harris Hip Score was slightly lower than that of the proximal femoral nail group. However, at the three‐ and six‐month monthly follow‐ups, the dynamic hip screw group presented higher mean scores than the proximal femoral nail group; at the one‐year follow‐up, both the groups attained similar scores. Conclusion: Proximal femoral nail provides a significantly shorter surgery with a smaller incision that leads to less wound‐related complications. However, the incidence of technical errors was significantly higher in proximal femoral nail when compared with dynamic hip screw as it is a technically more demanding surgery that leads to more implant failures and the consequent re‐operations.
