Evaluation of functional outcome and comparison of three different surgical modalities for management of intertrochanteric fractures in elderly population.

Abstract

Introduction: The purpose of this study was to compare the role of the various surgical modalities ie, Hemiarthroplasty (HA), Dynamic Hip Screw (DHS), Cephalo-medullary nail (CMN) in the management of intertrochanteric fractures in elder patients with comparison of the results and assessment of the complications encountered with each method.

Methods: Total 105 adult patients having intertrochanteric fractures managed during July 2013 to December 2018 at tertiary trauma care centre and followed for minimum 12 months were included in the study. Patients were divided into three groups. Primary hemiarthroplasty was done in 35 patients (group A) while DHS and PFN was done in 35 patients each in group B and group C respectively. Functional evaluation was done using Modified Harris Hip score (HHS) at different intervals while ambulatory function was measured using the Parker Mobility Score.

Results: The mean age of patients was 72.14±2.9 years. Mean operative time and blood loss in group A was significantly higher than the other two groups. Hemiarthroplasty group could ambulate earlier than DHS/PFN group. Mean HHS at final follow up was 85.40±7 in group A while in group B and group C these values were 76.36±16.45 and 86.85±10.52 respectively. HHS was significantly higher (P, 0.01) in hemiarthroplasty group in comparison to DHS group. Post-operative complications were comparable in all the groups.

Conclusion: We support the use of hemiarthroplasty for unstable intertrochanteric fracture in elderly patients with lesser failure rates, early mobilization and better functional outcomes. Early mobilization and less hospital stay should be the goal of every surgical procedure in the elder population.
