Unipolar versus bipolar hemiarthroplasty for femoral neck fractures: is there a difference?
Bhattacharyya, Koval (2009) Unipolar versus bipolar hemiarthroplasty for femoral neck fractures: is there a difference? J Orthop Trauma (IF: 1.8) 23(6) 426-7Abstract
Arthroplasty has been shown to reduce the rate of reoperation after femoral neck fracture. A number of studies have compared the outcomes of unipolar and bipolar arthroplasty. At 1- to 3-year follow-up, the functional outcomes of unipolar and bipolar arthroplasty are equivalent. Bipolar arthroplasty has a higher initial cost. However, the long-term results of acetabular wear and need for revision are unknown.
