Identifying Safer Implant Designs for Total Hip Replacement

Total hip replacement (THR) is becoming increasingly common, but postoperative femoral fractures remain a major problem. In a recent study, researchers from Japan compared two widely used femoral stem designs—a key component of hip prostheses—in a large cohort of patients who underwent THR. They found that collared, fully hydroxyapatite-coated stems significantly reduced early femoral fracture risk compared to flat-tapered wedge stems, offering valuable insights for improving patient safety and surgical outcomes in THR.
