POLARSTEM◊ Cementless and Cemented Stem System for primary hip replacement
POLARSTEM offers several design features that assist with muscle sparing approaches: • Thick proximal area to help reduce the risk of subsidence • Shorter stem length than other fully HA coated stems • Thin distal area with a narrow tip, making it easier to implant through a smaller incision • Broaches with compaction teeth anterior/posterior and bone cutting teeth medial/lateral that allow for an optimal fit between the stem and cortical bone • 180 microns of Ti-plasma spray plus 50 microns of HA
