Materials and Methods: At Indira Gandhi Medical College in Shimla's orthopaedic surgery department, the current study was carried out. It comprised instances that were both prospective and retrospective and who underwent modular bipolar hip arthroplasty following hip surgery using the posterolateral method for an unstable femur neck fracture. 35 patients were enrolled in a prospective case starting in May 2016 and 25 traceable operated patients were included in a retrospective study over the previous five years. Results: The mean average age of the patients was 78.5±6.87 years with female predominance of 67% and involving left side in 57% of patients. Out of 60 patients, 4 patients died while 2 patients could not be followed-up; hence, score were calculated only for 54 patients. Out of these 54 patients, 2 (3.8%) had excellent results with Modified Harris Hip Scores of more than 90, 22 (40.7%) had good results with scores 80 to 89, 22 (40.7%) patients had fair outcomes with scores 70 to 79 and 8 patients (14.8%) had poor results with scores <70. The final follow-up Modified Harris Hip score in different age group were found to be almost similar. Similarly, the final Modified Harris Hip score were found to be almost similar between males and females. The comparison of prospective patients on preoperative and postoperative Modified Harris Hip score was found to be statistically insignificant. The age group based comparison between preoperative and postoperative score in prospective patients of different age groups were found to be statistically not significant Similarly, Sex based comparison between males and females of Modified Harris Hip score were found to be statistically insignificant (p>0.05). Conclusion: We therefore concluded that modular bipolar hip arthroplasty for displaced fracture neck of femur is the best available treatment option in advanced age with good functional results.
