I have attached the most recent article on the topic of Shoulder arthroplasty in young patients (patients 55yo or younger) with osteoarthritis (J Shoulder Elbow Surgery Jan 2011) on the shoulder page of this web site.

The purpose of the study was to define results, complications, and frequency of revision surgery in this group. Open the PDF above and read the abstract. In a nutshell, Mayo Clinic's Dr Cofield reports favorable outcome in this group, and acknowleges that pain relief, range of motion, and implant survival were better after Total replacement as compared to Hemiarthroplasty.
This is important information because historically surgeons have been inclined to recommend Hemis in younger patients for fear of glenoid loosening. Dr Cofield's findings actually suggest that a Total is a better option--10 year survival was 92% compared to 72% after a Hemiarthroplasty. Moderate to severe glenoid erosion was present in 6 of 13 Hemiarthroplasties.
At least as of 2011, the evidence seems to support Totals rather than Hemi's even in younger patients. Newer, more anatomic designs and better glenoid fixation have been instrumental in improving outcomes---but longer term follow-up will be important. To the extent that pain relief and range of motion gains are primary indications for shoulder arthroplasty, this Jan 2011 study provides valuable informaton.
An ongoing question regarding activity/lifting restrictions in this patient population exists. As this information becomes available, I will share it.
