Comparative Bony Union Time Analysis of Dynamic Hip Screw and Proximal Femoral Plate Implants

Abstract

Objective: To examine the comparative and effective applicability of Dynamic Hip Screw (DHS), and Proximal femoral plate (PFP) to establish a rapid bony union with the least complications for the treatment of unstable pertrochanteric fractures

Methodology: The effectiveness of both techniques was assessed by implanting DHS or PFP as an intervention in 84 healthy participants divided into two groups (DHS and PFP; 42 participants each). implantation, the bony union was clinically and radiographically screened at follow-ups after 6 weeks of operation, and later on, 2 weekly for up to 3 months.

Results: A total of 84 participants with a mean age of 68.36 years (65.5% females and 34.5 % males) were provided with DHS or PFP interventions. Corresponding outcomes involved bony union at 2.7 months ± 0.2 in DHS implants and 2.9 months ± 0.1 in the PFP fixation group. Complications involved superficial (6%) and deep wound infections (3.6%) in both groups. However, varus collapse (13.1%) was exclusively detected in DHS surgeries.

 Conclusion: Implications from the study have unveiled the efficiency of PFP as a treatment of unstable pertrochanteric fractures for the achievement of rapid bony union with minimum complications.
