Key result
PFN linked to ~32% shorter surgery and less blood loss vs DHS for intertrochanteric fractures.
Why the study?
Dynamic Hip Screw is the most commonly used device for fixation of intertrochanteric fractures, while Proximal Femoral Nail is the latest implant, prompting a comparison of their results.
Does Proximal Femoral Nail (PFN) improve surgical outcomes compared to Dynamic Hip Screw (DHS) in patients with intertrochanteric fractures?

Does Proximal Femoral Nail (PFN) improve surgical outcomes compared to Dynamic Hip Screw (DHS) in patients with intertrochanteric fractures?
Absolute Event Rate: 60% vs 87.8%
p-value: p=<0.001
PFN is associated with reduced surgical time and blood loss compared to DHS for intertrochanteric fractures, though hospital stay and union time are similar.
May favor PFN over DHS to reduce operative burden in intertrochanteric fractures; leaves open randomized confirmation of outcomes.
Background: Intertrochanteric fractures are those occurring in the region extending from the extracapsular basilar neck region to the region along the lesser trochanter. D.H.S (Dynamic Hip Screw) with side plate assembly is most commonly used device for fixation of intertrochanteric fractures. The latest implant for management of intertrochanteric fracture is the P.F.N (Proximal Femoral Nail). In view of these conditions, this study is taken up to compare the results of D.H.S and P.F.N.Materials and Methods: The study comprised of 50 patients as per the inclusion criteria and two groups were made, one operated with DHS while other operated with PFN with 25 patients in each group.Results: We found 25 patients each in D.H.S. and P.F.N. group, 64% of the cases being females and 52% of the cases with unstable fractures, we found that the average surgical time was significantly less for P.F.N. than for D.H.S. Also the average blood loss for D.H.S. surgery was significantly more than for P.F.N.Discussion: There was no significant difference in the duration of hospital stay and the time required for the fracture to unite in both the modalities of treatment.

Rawate Praful (2020) conducted a cohort in Intertrochanteric fractures (n=50). Proximal Femoral Nail (PFN) vs. Dynamic Hip Screw (DHS) was evaluated on Average surgical operative time (minutes) (p=<0.001). Proximal Femoral Nail (PFN) significantly reduced average surgical time (60.0 vs 87.8 minutes) and intraoperative blood loss (85 vs 280 ml) compared to Dynamic Hip Screw (DHS) in patients with intertrochanteric fractures.
