The POLARSTEM has been clinically used since 2002 and is based on a philosophy that has yielded excellent clinical results in the last 25 years. The simple surgical technique leads to reproducible results and allows implantation using both conventional and minimally invasive techniques. It can be used for all standard femoral morphologies. The range of stems allows the implant to be matched to all bone sizes, thereby reproducing the natural hip architecture.
The non-cemented POLARSTEM range includes 12 standard femoral stems with a CCD angle of 135° and 10 lateral femoral stems with a CCD angle of 126°. All non-cemented implants are coated with an open-pored titanium plasma/HA coating.
The highly polished cemented POLARSTEM range includes 9 standard femoral stems and 8 lateral femoral stems.
Reinforced proximal section
Shorter and narrow distal section
Prevention of subsidence
Increased rotational stability
Excellent primary stability and accelerated osseointegration. The stems are coated with high grade, open-pored pure titanium applied by vacuum plasma spray.
A hydroxyapatite layer is applied to the open-pored titanium plasma coating in the same process step. The result: excellent adhesion.
The POLARSTEM Standard and Lateral Femoral Stems with Ti/HA are indicated for:
The POLARSTEM Standard and Lateral Femoral Stem with Ti/HA is intended for single use only and is to be implanted without bone cement.
