OptiStems - with conviction

At the origin of a customLINK idea, now available as a standard product. OptiStems are anatomical femoral stems that were developed as a stem portfolio expansion.

The Optimal Stem Option

  • Intraoperative freedom of choice between options, with 3 stem lengths each.
  • Free rotation adjustment to the femoral component via OptiStem adapter
  • Adequate leg length adjustment via adapter and choice of stem size.
  • Proven taper for reliable coupling

Anatomical Self-positioning

  • Based on scientific papers and decades of custom-made experience by LINK, developed for anatomical self-positioning.
  • Anatomical design takes the natural curvature of the femur into account: The next step to the classic cone–stem combination
  • Precise feedback prom instrumentation during implantation

Anchoring in the Restoration Zone

  • Rotational stability in the femur thanks to distal metaphyseal press-fit, oval stem cross-section, and anatomical curvature.
  • Oval stem design for lumen-filling fit, with stem diaphyseally tapering to a round cross-section in order to reduce the risk of bone stress.
  • Suitable for the Endo-Model SL and the new generation LINK Endo-Model EVO.

 

Tibial OptiStems are available on request as custom-made implant. Please contact us: customlink@link-ortho.com
