Abstract: Background and Objective: Hip fractures caused by osteoporosis have become a leading source of morbidity and mortality in the adult and elderly populations worldwide. Normal locomotion necessitates a stable, pain-free, and mobile hip. Displaced subcapital and intracapsular femoral neck fractures are usually treated with surgery. The study aims to assess the functional outcome of primary total hip arthroplasty in elderly patients with fracture neck of the femur.
Materials and Methods: Twenty-five patients with acute neck of femur fracture were treated with primary total hip arthroplasty between November 2019 to May 2021. All the patients were followed up for six months.
Results: There were 11 male and 14 female patients in our study. The most common mode of injury was trivial trauma. The primary total hip arthroplasty in fracture neck of femur in elderly population provided a mean Harris Hip Score of 81.1 at the end of 1 month, 83.9 at the end of 3 months, and 85.7 at the end of 6 months. The functional outcomes obtained were excellent results in 32%, good results in 52%, fair results in 12%, and poor results in 4% of the study population, with a ‘p value’ of 0.045. The poor outcome was recorded in 1 patient due to lack of mobilization secondary to recovery from covid pneumonia.
Conclusion: The key to success lies in selecting patients who are active, independent, mobile before the injury, motivated, and in a good mental state. We recommend the total hip arthroplasty as a primary procedure in elderly patients with fracture neck of femur for better function of the hip and to avoid further revisions in patients with long life expectancy.
