Combining unmatched clinical success with Biomet’s commitment to product innovation

Over the past 26 years, the Taperloc® Hip System has become the industry standard in cementless hip arthroplasty.1 Combining this unmatched clinical success with Biomet’s commitment to product innovation, the Taperloc® Complete Hip System has been introduced with design enhancements that include a 133º neck angle, extended anterior-posterior neck flats, smoothed distal transition and a polished neck. These enhancements, along with the key clinical aspects of the original Taperloc® hip stem, are designed to help surgeons restore leg length, stability, offset and range of motion accurately and consistently.

  • Design built upon the Taperloc® stem (launched in 1982) which is the longest clinically referenced primary hip stem with a wedge shape, titanium substrate and proximally circumferential titanium porous plasma sprayed design1-3
  • Simple broach-only surgical technique and simple instrumentation that can be used with a variety of surgical approaches 
  • Optimal 133º neck angle increases ROM, improve stability through increased soft tissue tension and allows for more use of standard and +3 modular head options for a better reproduction of hip biomechanics4-6
  • Polished anterior-posterior neck flats increase ROM by geometrically reducing the potential for impingement of the neck with the cup
  • Clinically proven PPS® coating allows for initial scratch-fit stability and bone fixation1,7-9
  • 3-degree bi-planar taper enhances proximal offloading and immediate stem/bone interface stability2
  • Consistent sizing (1mm increments) for optimal interchangeability, O.R. efficiency and accurate matching of the patient's femur without the need to remove additional bone
