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

Abstract

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