Taperloc® Complete Hip System

1000x1000_insetimage_Hips_Taperloc

Zimmer Biomet’s Taperloc Complete Hip System builds on the clinically proven Taperloc hip stem.1-3 Launched in 1982, the Taperloc Hip Stem is the longest clinically referenced hip stem with a wedge shape, titanium substrate, and proximally circumferential titanium porous plasma sprayed design.1-3 The system comes with easy-to-use instrumentation that accommodates a variety of surgical approaches, and uses a simple broach-only surgical technique.

The Taperloc Complete Hip System comprises of the following femoral prosthesis offerings:

  • Taperloc Complete femoral stem features a reduced distal geometry in which a gradual reduction of the stem substrate occurs distal to the porous coating level
  • Taperloc Complete Microplasty ® features a reduced stem length from the standard length stem to better address minimally invasive technqiues, providing an alternative to femoral resurfacing while offering a unique solution in cases where a bone conserving prosthesis is desirable
  • Taperloc Complete XR 123° helps address femurs with a more varus neck by allowing for additional offset to properly restore him biomechanics and soft tissue tensioning

The Taperloc Complete Hip System has since become the industry standard in cementless hip arthroplasty1. Combining unmatched clinical success with Zimmer Biomet’s commitment to product innovation, the Taperloc Complete Hip System has design enhancements that are intended to help surgeons restore leg length, stability, offset, and range of motion accurately and consistently. The features of the Taperloc Complete Hip System include:

  • Flat Tapered Wedge Geometry enhances proximal offloading and bone preservation and provides rotational stability
  • Optimal 133º Neck Angle increases ROM, improves 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 cup8
  • Clinically proven PPS® coating provides 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) provides optimal interchangeability, O.R. efficiency, and accurate matching of the patient's femur without the need to remove additional bone
  • Standard and High Offset Options reproduce various patient anatomies without lengthening the leg
  • Coxa Vara Option more closely reproduces varus anatomies 
  • Insertion Hole provides rotational stability upon implantation
  • Reduced Distal Transition enhances implant fit in femoral canals with a proximal/distal mismatch
  • Titanium Alloy Ti-6AL-4V construction allows for stress transfer to preserve cortical density
  • Full-length Stem available in full profile and reduced distal options
  • Microplasty Option retains same metaphyseal geometry while conserving bone and accommodating minimally invasive surgical approaches 
  • 100% Survivorship at a minimum 5 year follow-up in 39 rheumatoid patients2
  • 100% Survivorship at a 2–11 year follow-up in 114 patients 80 years old or older3
  • 99.6% Survivorship at a 12 year follow-up of 4,750 patients4
  • 99% Survivorship at a 22–26 year follow-up in 138 patients1
  • 99% Survivorship at a 12 year follow-up in 115 patients5
  • 98% Survivorship at 8–13 year follow-up in 91 patients 50 years old or younger6
  • 95% Survivorship at a 10–18 year follow-up in 89 obese patients7
  • 94% Survivorship at a 10–18 year follow-up in 99 non-obese patients7

 

  • PPS® Porous Plasma Spray
