- Purpose
To evaluate the results of intramedullary nailing with sliding restriction and dynamization methods in treating intertrochanteric fractures.
Materials and Methods
From August 2016 to March 2019, patients aged 65 years and older who underwent intramedullary nailing in treating intertrochanteric fractures were enrolled in this study. The radiological and clinical results were analyzed in 49 patients who had undergone lag screw sliding re-striction and dynamization of the distal interlocking screw method.
Results
Forty-seven patients achieved union without complications (95.9%). The mean union period was 6.5 weeks (range, 6-9 weeks). Complications occurred in two patients (4.1%), including the cut through of the lag screw in one patient and varus deformity of more than 10° in the other. The preinjury mean Koval grade was 2.8 (range, 1-7). The mean was 3.3 (range, 1-7) at the final follow-up, and the mean difference was 0.5 (range, 0-2).
Conclusion
Intramedullary nailing with a sliding restriction and dynamization method for treating in-tertrochanteric fractures achieved union. The reduction achieved during surgery was maintained with good clinical results. This method is a safe and effective treatment technique for femoral intertrochanteric fractures.
