Key result
Bipolar prosthesis resulted in a higher mean Harris hip score (90.03) compared to Austin Moore prosthesis (84.4) in elderly patients with displaced femoral neck fractures, alongside better functional outcomes and fewer complications.

In elderly patients with femoral neck fractures, bipolar prosthesis provides better pain relief and specific functional improvements compared to Austin Moore prosthesis, though overall Harris Hip Scores were not statistically significantly different.
Favors bipolar over Austin Moore prosthesis for function and complications in elderly femoral neck fractures; extends RCT evidence for this comparison.
Femoral neck fractures have been considered 'Unsolvable fracture' in the olden era of orthopaedics due to high rate of associated complications, which include nonunion and avascular necrosis of the femoral head. Prosthetic replacement as a primary procedure eliminates osteonecrosis and non-union as complications of femoral fractures and also allows immediate weightbearing to return elderly patients to activity and help avoid complications of recumbency and inactivity. The decision to perform hemiarthroplasty using a unipolar or bipolar prosthesis remains controversial with proponents on either side. So in view of varied opinions, we desire to compare the efficiency of these two prosthesis, unipolar and bipolar prosthesis for the management of intracapsular fracture neck femur in elderly.

Krishna et al. (2015) conducted an RCT in Acute displaced fracture of the femoral neck (n=104). Bipolar prosthesis vs. Austin Moore Prosthesis (AMP) was evaluated on Mean Harris hip score (p=0.273). Bipolar prosthesis resulted in a higher mean Harris hip score (90.03) compared to Austin Moore prosthesis (84.4) in elderly patients with displaced femoral neck fractures, alongside better functional outcomes and fewer complications.
