LINK OptiStem
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. https://customlink.solutions
