Conversion of Hip Hemiarthroplasty to Total Hip Arthroplasty Utilizing a Dual-Mobility Construct Compared With Large Femoral Heads

Larger effective femoral heads used during conversion of hemiarthroplasties to THAs resulted in high survivorship free of revision, minimal complications, and excellent clinical outcomes at short-term follow-up. In patients at highest risk for postoperative dislocation, including those with dislocating hemiarthroplasties, DM constructs resulted in no postoperative dislocations.
