- Abstract
- Femoral stem fixation for displaced femoral neck fractures in osteoporotic patients is an ongoing debate. We evaluated the outcome of 136 cementless bipolar hemiarthroplasty using a Micro-arc oxidation (MAO) coated stem. All patients survived the procedure and were discharged from the hospital. Thirty-and 90-day mortality rates were 0.7% and 2.2%, respectively. Ninety-eight hips were followed for a minimum of 2 years (mean, 44 months) postoperatively. Three stems were revised because of a periprosthetic fracture. Although cortical stress shielding around the stemwas observed in 3 hips, therewas no loosening or osteolysis. Cementless bipolar hemiarthroplasty using a MAO-coated stem is a useful and safe option to treat displaced femoral neck fractures. (C) 2014 Elsevier Inc. All rights reserved.
