Reverse Shoulder Arthroplasty: How It Works

  • Bruno Toussaint
  • Jérôme Bahurel


The semi-constrained reverse shoulder arthroplasty (RSA) designed by incorporating Grammont’s work allows us to treat complex shoulder conditions, such as irreparable rotator cuff tears, eccentric shoulder osteoarthritis (OA), rheumatic diseases, and trauma in elderly patients. In other words, all those conditions where all other shoulder arthroplasty designs had failed.

The rationale of RSA has been supported by various biomechanical studies and by the development of several implant designs. Scapular notching is an unfavorable effect of this type of prosthesis, albeit it does not necessarily compromise the longevity of the implant. Understanding of this phenomenon has opened the way to its prevention.

Recent studies showed improved survival of RSA. This is promising and allows the range of indications to be widened.
