title: A proximally coated beaded stem minimum 5-year follow-up.
abstract: This study reports the minimum 5-year clinical and radiographic outcome of a proximally beaded stem. A consecutive series of 159 primary uncemented total hip arthroplasties in 153 patients were evaluated clinically and radiographically by prospectively determined criteria. Radiographic results showed 97% of the femoral stems are bone ingrown and stable by Engh criteria. There have been 5 femoral revisions (2 for subsidence, 2 for loosening, and 1 broken trunion). At minimum 5-year follow-up, this femoral stem has demonstrated reliable clinical function, bone ingrowth, and proximal bone preservation.
