Comparison between Total Hip Replacement and Internal Fixation for the Treatment of Displaced Femoral Neck Fractures in Elderly Patients: A comparative longitudinal study

Abstract

Aim: To Compare between Total Hip Replacement and Internal Fixation for the Treatment of Displaced Femoral Neck Fractures in Elderly Patients

Study design: Comparative longitudinal study

Place and duration: This study was conducted at Pakistan Institute of Medical Sciences Islamabad Pakistan from Jan 2020 to Jan 2021.

Methodology: A total of 80 patients with femoral neck fracture were included in this study. The study participants were divided into, Group A treated with internal fixation and Group B treated with THR. Harris hip score, time patient, stayed at the hospital, blood loss, and surgery time was recorded. Statistical analysis was performed using SPSS software version 22 to compare the functional outcomes of both groups.

Results: Harris hip score was statistically significantly higher in the total hip replacement group after 12-month follow-up as compared to the internal fixation. There was no significant difference found in both the groups in terms of associated complications. The average Harris hip score was significantly higher in total hip arthroplasty (96.2) as compared to the internal fixation (92.3). There was a strong association found between the non-union and avascular necrosis and the advanced age indicating that the risk of complications increased with the progression in age.

Conclusion: It is concluded that primary hip arthroplasty is found to be a safe treatment strategy for elderly patients as it provides better functional outcomes and fewer complications as compared to internal fixation.
