How is primary stability achieved for the SL-PLUS® stem during surgery?
The implant is anchored in a precisely-reamed bone bed through a press-fit connection. At the proximal end close contact is achieved over a wide area between the implant and the cancellous bone that has been compacted by the reaming process. At the distal end the stem edges penetrate the prepared endosteal cortical bone. The stem is further secured through torsional and vertical forces. Secondarily, this leads to compression of the bone along the stem edges, thereby promoting bone ongrowth or osseointegration.
