Comparison of revision rates and radiographic observations of long and short, uncoated and coated humeral stem designs in total shoulder arthroplasty

[摘要] Total shoulder arthroplasty (TSA) with uncemented humeral stems – also known as press-fit stems – has become the standard treatment for glenohumeral osteoarthritis with intact rotator cuffs.1,2 While TSA grants satisfactory functional improvements and pain relief,3,4 it is frequently associated with failures of the glenoid component. Aseptic loosening of the humeral implant is less commonly described, although it is a potential long-term problem,5 with a reported rate of 9% of humeral loosening at 20 years.
