Comparative Study Between Monopolar and Bipolar Hemi-replacement Arthroplasty for Fracture Neck Femur in Old Age

Hemi-Replacement of the Hip Joint is a surgical procedure used to treat certain types of displaced femoral neck fractures, especially in elderly patients. Hemiarthroplasty involves replacing only one half of the hip joint, typically the femoral head, while preserving the acetabulum (hip socket). There are mainly two types of hemi-replacement based on using of implants 1) Mono-polar 2) bipolar This study aims to conduct a meta-analysis comparing unipolar and bipolar implants used in hemiarthroplasty, with a focus on clinical outcomes, perioperative data, complication rates, and mortality.
