PFN VS DHS THESIS

Journal List Med Sci Monit v. Radiological evaluation of intertrochanteric fracture fixation by the proximal femoral nail. However conservative treatment usually resulted in malunion. Type of surgery and details were noted. Operative time Four studies [ 10 , 12 , 14 , 15 ] provided data on operative time. The average time taken for mobilization from the time of surgery for PFN series was 1. Intramedullary devices like the proximal femoral nail have been reported to have an advantage in such fractures as their placement allowed the implant to lie closer to the mechanical axis of the extremity, thereby decrease the lever arm and bending moment on the implant.

Abstract Background The aim of this meta-analysis was to compare the outcomes of proximal femoral nail PFN and dynamic hip screw DHS in treatment of intertrochanteric fractures. There are several limitations in our meta-analysis. Conclusions In summary, the current available data indicate that PFN may be a better choice than DHS in the treatment of intertrochanteric fractures. Surgery was performed on average of 3 days with a range of days. The results of this meta-analysis also demonstrates that operative time, intraoperative blood loss, and length of incision in the PFN group are significantly less than in the DHS group. This led to internal fixation of these fractures to increase patient comfort, facilitate nursing care, decrease hospitalization and reduce complications of prolonged recumbency. J Injury Feb, 24 2 ;

These were commonly seen in Type IVV fractures and in obese individuals. Four studies [ 10121415 ] provided data on operative time.

No post-operative complications were seen in PFN series. JBJS,60 A Radiological evaluation of intertrochanteric fracture fixation by the proximal femoral nail. In one case, fixation of the fracture occurred in varus angulation.

Discussion The varus collapse of the thesid and neck caused by lag screw cut-out or lateral protrusion is one of most common post-operative complications that lead to surgical failure in treatment of intertrochanteric fractures. Fixation of intertrochanteric fractures of the femur.

Vol 1, pages The study quality was assessed according to whether allocation concealment was: Both the patients were lost during the 2nd djs of follow up. No post-operative complications were seen in PFN series.

The average time taken for DHS procedure was How to Cite this Article: Subtrochanteric fractures, Clin Orthop Though both PFN and DHS have similar functional outcome in stable fracture and PFN has better function outcome with unstable fractures, PFN requires shorter operative time and a smaller incision, it has distinct advantages over DHS even in stable intertrochanteric fractures.

The number of fractures included in a single study ranged from 64 to Furthermore, not all the studies included had long enough follow-up periods, which also reduces the power of our research. Indian Journal of Orthopaedics35 2: Return to normal function.

There was no mortality in this study. Another explanation for cut-out is that because the screw is rotationally unstable within the bone when a single lag screw dhw used, flexion-extension of the limb results in loosening of the bone screw interface, leading to the secondary cut-out of the screw.
