Microfractor PULSEShifter

To the point

Apart from cartilage transplantation (mosaic plastic surgery) and autologous chondrocyte transplantation, microfracturation has now become a very widespread method for treating cartilage defects. Microfracturation ranks among the bone-marrow stimulating procedures and is applied in cases of restricted cartilage damage that goes deep into the bone.

This successful procedure is therefore also applied in hip joint arthroscopy. However, the pronounced curvature of this ball joint means that it is frequently difficult to guide the direction of force applied at the tip of the microfractor perpendicular to the cartilage-bone surface. However, this is necessary in order to prevent the microfractor sliding and hence to avoidpreventing damage to the surrounding cartilage. It is also necessary to achieve sufficiently deep penetration of the surface.

In order to match the anatomical characteristics of the hip joint, in microfracturation, the PULSEShifter was developed to create an instrument that uses a patented solution. This to guides the impact pulse along the sheath curved at the distal end (45°) virtually without loss and conducts it "round the corner" into the movably mounted tip of the instrument.
