Long PFNA-II versus Dynamic Hip Screw for Treatment of Unstable Intertrochanteric Femur Fracture

Abstract

Background: Intertrochanteric femur fractures are one amongst the most common hip fracture presenting to our centre. Clinical efficacy and safety of PFNA and DHS in the treatment of unstable intertrochanteric fractures in elderly patients and found that compared with the control group (DHS), the observation group (PFNA) experienced shorter operation time and fracture healing time and less intraoperative blood loss, and suffered a shorter incision. The purpose of this study was to compare the functional outcomes and related complications between DHS and PFNA in treatment of unstable intertrochanteric femur fracture. Methodology: Total of 60 patients having unstable intertrochanteric femur fracture were included in this study and was equally divided into two groups. Group-P included patients with unstable intertrochanteric femur fracture managed by PFN-A II while Group-D patients managed by DHS. The result was analysed using descriptive statistics and making comparisons among various groups. Categorial data were summarized as in proportions and percentage (%) while discrete as mean ± SD. Results: At final follow-up; it was found that 72.4% of the cases of PFNA have achieved excellent union as compared to 44.4% for DHS group, 24.1% cases of PFNA have good union as compared to 51.9% in DHS group and the difference of mean DHS was significantly higher for PFNA group (p=0.001). Conclusion: PFNA-II have benefits like minimally invasive procedure, less soft tissue dissection, less amount of blood loss and provides better result in terms of union. Therefore PFNA-II is recommended as a better choice as compared to DHS in management of unstable intertrochanteric fractures in terms of functional outcome.
