Cemented Modular Bipolar Hemiarthroplasty for Displaced Femoral Neck Fractures in the Elderly.

Objective To determine the outcomes of cemented modular bipolar hemiarthroplasty for displaced femoral neck fractures in the elderly. Methodology This prospective study involved 102 elderly patients with clinically and radiologically confirmed displaced femoral neck fractures and was conducted in the Department of Trauma and Orthopedic Surgery, Unit-1, Services Hospital, Lahore. Cemented bipolar hemiarthroplasty was performed on all patients. Preoperative variables included gender, laterality, and age. Postoperatively, the Harris Hip Score (HHS) at set follow-up intervals was measured to assess functional outcomes. Data analysis was conducted using JASP Team (2024), JASP (Version 0.19.0) (Computer software). Normality tests were applied to check for data distribution. As the data was non-parametric, further nonparametric tests for correlation and significance were applied. Results The study included 56 males and 46 females, with a mean age of 65.45 years. The majority of the procedures were left-sided (55). Cemented modular bipolar hemiarthroplasty was performed for displaced femoral neck fractures. The mean HHS at 6 weeks, 3 months, and 6 months follow-up was 78.15, 83.49, and 88.76, respectively. Complications were observed in 14 (13.7%) patients, with superficial surgical site infections (SSIs) being the most common. No cases of hip dislocation or acetabular erosion were reported during the follow-up. Conclusion The study concludes that cemented modular bipolar hemiarthroplasty provides better functional outcomes for elderly populations with osteoporotic bones who tend to have a relatively sedentary lifestyle.
