Reverse total shoulder (TESS) – high rate of glenoid loosening
These authors reviewed 37 consecutive patients (40 shoulders) underwent TESS RSA (see figure below) between October 2007 and January 2012; 16 were stemless and 26 were stemmed. At a mean follow-up of 39 months (15-66) there were four glenoid loosenings. In 12 shoulders had developed scapular notching and seven already had scapular bone impression evident on initial post-operative radiographs.
Comment: We have no experience with this prosthesis. It appears that the quality of glenoid fixation with this system may be less robust than some other systems.
