Evaluation of functional outcome of cemented bipolar prosthesis in femoral neck fracture in old age patients

Background: Older adults are at a higher risk of proximal femur fractures, particularly femoral neck and intertrochanteric fractures, often due to falls, trauma, or osteoporosis. Managing these fractures in osteoporotic bones is challenging, as they are associated with complications such as pressure sores, deep vein thrombosis, and hypostatic pneumonia. This study aimed to evaluate the outcomes of treating femoral neck fractures in elderly patients using cemented bipolar prosthesis. Methods: A quasi-experimental study was conducted on 40 patients aged 60 to 84 years who underwent cemented bipolar hemiarthroplasty within 21 days of fracture from January 2019 to December 2019. Post-operative functional outcomes were assessed using the Harris hip score (HHS) at 3, 12, and 24 weeks, both clinically and radiologically. Results: Of the 40 patients, 65% were female, and 52.5% had left-sided fractures. The majority (55%) experienced trivial falls. The HHS improved significantly from a mean of 43.73±6.78 at 3 weeks to 82.56±9.13 at 6 months. Garden type 3 fractures were the most common (70%). Functional outcomes were graded as good in 72.5% of patients, excellent in 17.5%, and fair in 5%, while 2.5% had a poor outcome. One patient (2.5%) died due to pulmonary embolism. Conclusions: Cemented bipolar hemiarthroplasty in elderly patients with femoral neck fractures is a safe and effective treatment, promoting early mobilization and reducing the risk of complications such as bed sores, deep vein thrombosis, and hypostatic pneumonia.
