A comparative study of studying osteosynthesis in intertrochanteric fractures using dynamic hip screw and proximal femoral nail

Abstract

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.
