Outcome of Bipolar Hemiarthroplasty in Neck of Femur Fractures

Background and objectives: Femoral neck fractures are a major cause of morbidity, particularly in older adults. Bipolar hemiarthroplasty (BHA) is commonly used for their management due to its favorable outcomes in function and mobility. This study aimed to determine the distribution of functional outcomes after bipolar hemiarthroplasty in neck of femur fractures and assess their association with demographic and clinical variables. Methodology:  It was a descriptive study, conducted at Department of Orthopedic Surgery, Allied Hospital, Faisalabad from: 27-Feb-25 to 27 May 2025.  A total of 156 patients aged 18–65 years who underwent BHA for acute femoral neck fractures were enrolled through non-probability purposive sampling. Patients with pre-existing hip disease, pathological fractures, or nonambulatory status prior to injury were excluded. Functional outcome was assessed at 3-month follow-up using the Harris Hip Score (HHS), categorized as excellent, good, fair, or poor. Results: Of the 156 patients, 47.4% achieved excellent outcomes and 31.4% had good functional outcomes. No statistically significant association was found between functional outcomes and age, gender, comorbidities, education level, socioeconomic status, implant type, or surgical approach (p > 0.05). Trends favored better outcomes in younger age groups, males, and cemented implant users. Conclusion: Bipolar hemiarthroplasty provides favorable short-term functional outcomes for femoral neck fractures. Although no significant predictors of outcome were identified, cemented fixation and posterior approach may offer modest functional advantages. Further studies with longer follow-up are recommended.
