Abstract
The management of neck of femur fractures, particularly in the elderly population, remains a significant challenge in orthopedic surgery. Bipolar hemiarthroplasty is a commonly performed procedure for these fractures, offering pain relief and functional restoration. This retrospective case series compares the clinical outcomes of bipolar hemiarthroplasty using modular versus monoblock prosthesis in patients with neck of femur fractures. The study includes patients aged 65 years and older who underwent the procedure between January 2018 and December 2022. Clinical outcomes were assessed using the Harris Hip Score (HHS), incidence of complications, prosthesis-related issues, and patient satisfaction. The results indicate that modular prostheses offer superior functional outcomes and customization benefits, while monoblock prostheses provide simplicity and stability. However, the modular group demonstrated slightly better functional outcomes and patient satisfaction. The choice of prosthesis should be tailored to the individual patient’s needs, considering factors such as bone quality, fracture type, and surgeon expertise. Further studies with larger sample sizes and longer follow-up periods are necessary to validate these findings and provide more definitive recommendations.
