Long term functional outcome of unipolar and bipolar hemiarthroplasty in femur neck fracture among the elderly at Wahidin Sudirohusodo Hospital, Makassar, Indonesia


Background: Femur neck fracture has been known since Hippocrates’ time and is a common orthopaedic condition among the elderly. Since the dawn of time, several treatment procedures have been used. However, the question behind the situation remains unresolved to this day. This study aims to investigate the long-term functional outcomes of unipolar Austin Moore Prosthesis (AMP) hemiarthroplasty and bipolar hemiarthroplasty in elderly patients with femur neck fracture.

Methods: A 10-year retrospective study was conducted at Wahidin Sudirohusodo General Hospital, Orthopaedic and Traumatology Department, Universitas Hasanuddin, Makassar, from January 2009 to December 2018. The study included elderly patients aged 60 and over with a displaced femoral neck fracture treated with unipolar hemiarthroplasty (Austin Moore Prosthesis) or bipolar hemiarthroplasty.

Results: 11 females (83%) and one male in total (17%). Most patients were between 64 and 85, with an average age of 75.17. With a p-value of 0.935, the unipolar group has a higher mean total score of 64,9 than the bipolar group of 59,7. Overall, females were more likely to be involved than males. There was no change in functional results in both the unipolar and bipolar groups when the modified Harris Hip Score (mHHS) was varied. There were no differences in a functional result or total hip score between the two groups using the modified Harris Hip Score.

Conclusion: The functional outcomes of patients treated with unipolar prosthesis and those treated with bipolar prosthesis are not significantly different. Hemiarthroplasty of the hip for femoral neck fractures is a valuable alternative in older patients with good long-term functional outcomes, and unipolar hemiarthroplasty and bipolar hemiarthroplasty are still relevant to utilize in the present period.
