Comparison of Clinical Function Outcomes of Patients Performed with Cemented and Uncemented Bipolar Hemiarthroplasty Surgery on Femoral Neck Fractures Using Modified Harris Hip Score and Proportion of Dislocations after Hip Joint Replacement Surgery in Medan

Abstract

Introduction Fractures of the neck femur that occur in the elderly are caused by minor trauma with most common age more than 50 years old. While in young adult patients, fractures of the neck femur are caused by severe trauma such as a fall from a height or a traffic accident. Hemiarthroplasty cemented or uncemented are the most common methods of treatment neck femur fracture in elderly patients. Modified Harris Hip Score (MHHS) is a tool to measure the functional capacity and pain to assess the conditions of the patients before and after surgical procedures Methodology This is an observational analytic research study with a case control design at Adam Malik Hospital Medan and several network hospitals in Medan. Total of 32 patients with age more than 50 years old were diagnosed with femoral neck fracture with 16 patients underwent cemented bipolar hemiarthroplasty and 16 patients underwent uncemented bipolar hemiarthroplasty surgery during the period September 2021 until August 2022 assessed clinical functional outcome with MHHS scores and the proportion of dislocation 1 month postoperative. Result Mean MHHS value for cemented bipolar hemiarthroplasty was 79.00±5.40 and uncemented bipolar hemiarthroplasty 78.81±7.43 and there were no dislocations 1 month post operation. Discussion Statistical analytic using independent T-Test showing there was no significant different between MHHS scores in cemented bipolar arthroplasty and uncemented bipolar hemiarthroplasty 1 months post operative with P Value 0.935 (>0.05) without any dislocations was found.
