The Taperloc Complete Hip System has since become the industry standard in cementless hip arthroplasty.1 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 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® Femoral Stem
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 solution in cases where a bone conserving prosthesis is desirable
Taperloc Complete XR 123° Femoral Stem
Helps address femurs with a more varus neck by allowing for additional offset to properly restore hip biomechanics and soft tissue tensioning
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 biomechanics6-8
Increase ROM by geometrically reducing the potential for impingement of the neck with the cup9
Coating provides initial scratch-fit stability and biological fixation9-11
Enhances proximal offloading and immediate stem/bone interface stability2
Reproduce various patient anatomies without lengthening the leg
More closely reproduces varus anatomies
Provides rotational stability upon implantation
Enhances implant fit in femoral canals with a proximal/distal mismatch
Allows for stress transfer to preserve cortical density
Available in full profile and reduced distal options
Retains same metaphyseal geometry while conserving bone and accommodating minimally invasive surgical approaches
Design built on the Taperloc stem (launched in 1983), the longest clinically referenced1-3 primary hip stem with:
Proximally circumferential titanium porous plasma sprayed design
Designed to Treat a Range of Patient Anatomies
Microplasty (35 mm length reduction)
Consistent Sizing (1 mm increments)
Designed to provide optimal interchangeability, O.R. efficiency, and accurate matching of the patient's femur without the need to remove additional bone
The Taperloc Complete Hip System is compatible with ONE Planner Hip, a web-based preoperative planner for primary total hip arthroplasty. Using the auto-plan mode, surgeons can create a preoperative plan within five minutes.
ONE Planner Hip features an optional spinopelvic mobility assessment tool if both a sitting and standing lateral x-ray are provided with the AP X-ray. This web-based planner requires no onsite installation and adds no extra steps to the workflow.
