PFN, Stable, Locking DHS, Pertrochanteric, Outcomes


Background: In current practice, proximal femoral nail (PFN) and dynamic hip screw (DHS) with locking side plate are the implant of choice in stable trochanteric fractures. Most of the deficiencies of the standard DHS have been addressed by the introduction of the Locking side plate. There are plenty of studies comparing standard DHS and PFN. But studies comparing locking DHS and PFN are scarce in current literature. This study aimed to compare the outcomes of both implants in stable pertrochanteric fractures.

Methods: The objective of this study was to assess and compare the clinical outcomes of using locking DHS and PFN for fixation in 40 patients who were admitted to SUT Academy of Medical Sciences between October 2017 and April 2019. The modified Harris hip score was used to evaluate the patients' progress, and regular follow-up was conducted to compare their outcomes.

Results: Among the DHS group, the mean Harris hip score was 83.05, with excellent results observed in 2 patients (10%), good results in 12 patients (60%), fair results in 5 patients (25%), and poor results in 1 patient (5%). In comparison, the PFN group had a mean Harris hip score of 85.50, with excellent results seen in 6 patients (30%), good results in 10 patients (50%), fair results in 3 patients (5%), and poor results in 1 patient (5%).

Conclusions: The DHS group had more patients with good and fair outcomes, while the PFN group had more patients with excellent and good outcomes. Based on these findings, we can conclude that both the PFN and DHS with locking side plate are similarly effective in treating stable intertrochanteric fractures.
