Comparison of Rate of Dislocation after Bipolar Hemiarthroplasty through Hardinge`s Versus Moore`s Approach in Displaced (Garden`s Types III & IV) Neck of Femur Fractures.
J Pak Orthop Assoc Jan ;35(04):172-9.

Background: Hip fractures, constituting 20% of orthopedic trauma workload, often involve displaced Neck of femur (NOF) fractures. Elderly patients typically undergo Bipolar Hemiarthroplasty (BHA) using Hardinge`s or Moore`s approach. As debate on the preferred approach still persists in literature , this study aims to compare dislocation rates in BHA via Hardinge`s vs. Moore`s approach for displaced (Garden type III & IV) femur fractures. Objective: This study aims to compare the rate of dislocation after Bipolar Hemiarthroplasty (BHA) through Hardinge`s (Direct lateral) versus Moore`s (Posterior) approach. Methodology: It was randomized Control Trial with 60 patients (30 per group) in the Orthopedics Department, comparing Hardinge`s and Moore`s approaches for Bipolar Hemiarthroplasty. Follow-up data was analyzed using SPSS. Patient characteristics were expressed in frequencies, and quantitative data presented as mean -+ S.D. A p-value ? 0.05 indicated significance. Limitations included a small sample size and single-center study. Results: This study compares Hardinge Bipolar Hemiarthroplasty (HBH) and Moore Bipolar Hemiarthroplasty (MBH) outcomes in terms of patient demographics and dislocation rates. Demography , medication usage, and osteoporosis prevalence vary between groups. Dislocation rates at different time points show significant differences, notably at 6 months. Independent Sample t-test reveals a <0.05 p-value, indicating a significant association between MBH and dislocation at 6 month. Conclusion: There is a definitive difference in the rate of dislocation after bipolar hemiarthroplasty (BHA) through Hardinge`s versus Moore`s approach in displaced (Garden type III & IV) neck of femur fractures.
