ICJR Interviews: Reliable Fixation from a Press-fit Stem for RSA
A humeral stem utilizing press-fit fixation that Tom R. Norris, MD, thought he would use only for revision reverse shoulder arthroplasty procedures worked so well that since 2007, it has been his go-to implant for all reverse shoulder procedures – primary and revision – he performs.
An analysis of outcomes data on 219 patients showed his confidence in the stem is well founded: There were no instances of humeral loosening or subsidence, leading him to conclude that this press-fit stem offers excellent, predictable diaphyseal fixation in primary reverse shoulder arthroplasty (Figure 1).
In addition, he was able to retain and use the stem in 8 of 14 revision procedures he performed for failure of the initial reverse procedure.

Figure 1. The adjustable press-fit humeral stem system consists of a diaphyseal stem coated with hyaluronic acid; a smooth, detachable metaphyseal component; and smooth segmental stacking inserts. This system allows for easy, measured version adjustments in 10° increments and easy removal without removing the stem for revisions. Photo courtesy of Tom R. Norris, MD
