COMPARATIVE STUDY OF FUNCTIONAL OUTCOME OF HEMIARTHOPLASTY VS TOTAL HIP ARTHROPLASTY FOR THE TREATMENT OF DISPLACED INTRACAPSULAR NECK OF FEMUR FRACTURES IN ACTIVE ELDERLY PATIENTS

Abstract

Introduction- Hemiarthroplasty and total hip arthroplasty are commonly used to treat displaced intracapsular fractures of the femoral neck and the optimal treatment of these fractures remains controversial. Our aim was to analyse the functional outcome of these two different forms of treatment for the active patients aged > 60 years with displaced intracapsular fracture of the femoral neck.

Materials & Methods: A cohort study was conducted among the patients who had undergone either total hip replacement surgery or hemiarthroplasty for displaced intracapsular fracture neck of femur. The patient who were admitted at a tertiary care centre in Bangalore from January 2021 to January 2023 were recruited in the study. A total of 60 patients undergoing either unilateral total hip replacement/ hemiarthroplasty satisfying the inclusion criteria were included, 30 in each group. Pre operative diagnosis of intracapsular neck of femur fracture was confirmed with X-ray; Intraoperatively - surgical time, stability, offset and limb length were assessed using standard clinical methods; Assessment of Patient Reported Outcome Measures (PROM) was done using oxford hip score(OHS), 12 months post-surgery in both groups. The above mentioned parameters were compared to see if they have been restored and how these parameters alter the outcomes.

Conclusion: The study concluded that total hip replacement was a better option for the treatment of the displaced intracapsular fracture neck of the femur in active elderly patients aged >60 years, considering the improved functional outcomes in total hip replacement.
