Techniques in Shoulder & Elbow Surgery: March 2016 - Volume 17 - Issue 1 - p 2-4 doi: 10.1097/BTE.0000000000000077 Buy Metrics Abstract Modern component designs for total shoulder arthroplasty, including short-stem and stemless humeral components and hybrid glenoid components, show promising early and mid-term outcomes, but glenoid component failure remains the most common complication. Component loosening remains the leading cause of glenoid failure and must be the focus of future designs. Cemented all-polyethylene components, with or without bony ingrowth, and hybrid glenoid components presently show the most encouraging results with regard to long-term fixation and durability.
