Outcomes of Bipolar Hemiarthroplasty versus Dynamic Hip Screw Fixation in Patients with Basicervical Femoral Neck Fractures: A Randomized Controlled Trial

Abstract

 Aim: To compare the outcome of Bipolar Hemiarthroplasty versus Dynamic Hip Screw Fixation in patients with Basicervical Femoral Neck Fractures.

Study design: A randomized controlled trial

Place and Duration:  This study was conducted at Liaquat National Hospital and Medical College Karachi Pakistan from June 2020 to June 2021.

Methodology: This study includes 70 patients who were divided into two groups. One group was of bipolar hemiarthroplasty and the other of DHS fixation. Functional evaluation was made through questionnaires like Harris hip score HHS and visual analog scale VAS. There was a follow-up of one year.

Results: In the hemiarthroplasty group, the average age was 70.95±8.85 years and in the internal fixation group, it was 72.22±6.86 years. Two patients of the internal fixation group and three of the bipolar hemiarthroplasty group were excluded. There was not much difference in VAS scores of both groups but a significant difference in HHS scores of both groups. There were cases of device failure in the internal fixation group.

Conclusion: The comparison shows more good results of bipolar hemiarthroplasty over internal fixation by DHS due to lower revision rate, a short stay in the hospital, and lower device failure.
