Short-Term Results of the DePuy Global Unite Platform Shoulder System: A Two-Year Outcome Study

Background: The Global Unite Shoulder System is the next generation of implant from the Depuy Global Shoulderline. The primary feature of the Global Unite is adaptability through the interchangeable modular bodies, modular suturecollars, and stems. Short-term functional and radiographic outcomes of the Global Unite Platform Shoulder Systemwere assessed as well as complication and revision rates.Methods: 95 subjects were enrolled prospectively between 2013 and 2015 that underwent anatomic or reverseshoulder arthroplasty utilizing the DePuy Global Unite Anatomic Platform Shoulder System. Functional outcome data(ASES and SANE) as well as radiographic data was collected on these patients pre-operatively, and at 6 months, 1year and 2 years post-operatively.Results: The cohort consisted of 97 shoulders in 95 patients of which 54 (56.8%) are males and 41 (43.2%) are female.There were 55/97 (56.7%) were primary anatomic total shoulder arthroplasties, 37/97 (38.1%) primary reverse shoulderarthroplasties, and 3/97 (3.1%) revision procedures to a reverse shoulder arthroplasty. Outcome scores demonstratedan increase in ASES score from a mean of 33.00 to 79.56 and SANE score of 21.30 to 84.08.Conclusion: The Depuy Global Unite shoulder system demonstrated very good short-term results in this two-year outcomestudy. Functional outcome scores are similar to current literature for anatomic and reverse primary cases. Radiographicmeasures at two years are promising with only 2 cases of grade 1 scapular notching and one case of grade 2 scapularnotching. Overall the Depuy Global Unite is a versatile shoulder system with very good early outcomes.Level of evidence: IV
