SLR-PLUS

A message from the designer, Dr. Karl Zweymüller:

Revision hip arthroplasty for loosening is becoming an ever-increasing part of the orthopedic surgeon's practice. For primary hip replacement, non-cemented systems have been successfully used for many years. These devices obtain fixation by osseous integration into the host bone. The use of non-cemented implants at revision surgery seemed a natural progression; however, all too often negative trade offs had to be accepted.

The non-cemented revision devices previously available were suitable only for very straightforward or for very difficult cases. Now, at long last, there is a system to suit the middle range of hip revision arthroplasty: the SLR-PLUS Revision Stem can be used to manage many of the revision patients.

The new geometry of the SLR-PLUS stem makes use, above all, of the sound distal bone stock to obtain implant fixation. Together with the new design (with stem lengths to suit the revision situation), this feature makes for immediate stable fixation. Secondary fixation through osseointegration - and, hence, long-term clinical success - is brought about by the use of a forged titanium-niobium alloy component with surface roughness that has stood the test of time.
