Abstract

Bipolar hemiarthroplasty (BHA) for osteoporotic femoral neck fractures has a risk of proximal femoral fracture during trials, especially with larger trial bipolar shells. This study introduces a novel technique for BHA via the direct anterior approach, aiming to reduce trial use and lower the risk of iatrogenic femoral fractures. The "no trial reduction technique" involves positioning only the trial neck segment against the acetabulum's me-dial wall, without the bipolar shell and trial head. Fluoros-copy measures limb length differences to determine optimal femoral head and bipolar shell thickness, resulting in comparable limb lengths without early complications.
