A comparative study of hemiarthroplasty for neck of femur fracture of elderly (Bipolar, Austin Moore, cemented Thompson)‎

الملخص EN

Objective: This study was conducted to compare the hemiarthroplasties options in patients with neck of femur fractures with regards to the mortality rate and the functional outcomes.

Methods: A group of 153 elderly patients had been analyzed retrospectively, and these patients underwent 154 hemi arthroplastic surgeries for the hip joint due to neck of femur fractures between Jan 2012 and Jan 2014 (122 female, 31 male) at three hospitals; Prince Hashem bin Hussein Hospital, Prince Rasheed bin Hassan Hospital and the Royal Rehabilitation Center.

All the surgeons used a direct lateral approach.

The clinical records abstract form was designed to collect our study data which includes two important points; 1.

The mortality and morbidity rates of the hemiarthroplasties surgeries.

2.

The functional outcome of the bipolar prosthesis in comparison with the unipolar prosthesis using the Modified Harris Hip Score.

Results: The overall operative mortality rate of this study was 15%, and the mortality rate at 6 months was 44%.

But the bipolar prosthesis had a 12% operative mortality rate and 30% mortality rate after 6 months of surgery.

This result is statistically significant.

This research showed that the patients with bipolar prosthesis have had superior hip function during the follow up and they have had better pain scores than the patients with unipolar prosthesis.

Conclusion: There was a difference in mortality rate in favor of bipolar prosthesis .

Of the 52 patients who have been evaluated for up to 2 years it was found that there is a difference in functional out come in favor of bipolar prosthesis
