Background: Hip fractures are most encountered by Indian Orthopedicians. Hemiarthroplasty appears to be a more dependable and successful treatment for femur neck fractures. Modular hemiarthroplasty showed cutting-edge benefit due to its capacity to modify neck length in proportion to leg length and the tension of the abductors. The study evaluated functional outcome of modular bipolar hemiarthroplasty in fractured neck of femur using Modified Harris Hip Score (mHSS), pain and complication rate. Methods: This hospital-based prospective study done on 20 patients above 30 years with fracture neck of femur of <4 weeks admitted to Karnataka Institute of Medical Sciences, Hubballi. Postoperatively assessed with Modified Harris Hip Score, radiological outcome and pain with visual analog scale was assessed at 2 weeks, 6 weeks and 6 months. Appropriate statistical tests were applied. Results: The mean was 49.95± 6.9 years with majority 51 and 60 years. A male: female ratio was 1:1.5. Right-sided extremity with slip and fall as the most common mechanism of injury was noted. Modified HSS at 2 weeks, 6 weeks and 6 months was 67.25 ± 3.9; 76.85 ± 5.5 and 87.5 ± 5.11 respectively representing a statistical increase in the score (p<0.0001). The VAS at 2 weeks, 6 weeks and 6 months was 2.95 ± 0.7; 2.7 ± 0.4 and 1.75 ± 0.7 with statistical decrease in pain over time (p<0.0001). Overall, 5 cases encountered complications. Conclusion: Modular bipolar hemiarthroplasty for displaced femoral neck fractures offers pain relief, improved range of motion, and a quicker return to premorbid walking ability with a manageable complication rate.
