This Mayo Clinic retrospective series of 1584 primary shoulder arthroplasties (1984–2004) uses Kaplan-Meier and Cox regression analyses to define long-term humeral component survivorship and identify patient, implant, and surgical risk factors for humeral stem revision or removal.
When planning TSA, avoid metal-backed glenoid components in routine cases — the data show a 3-fold increase in humeral revision risk that is driven by glenoid-side failure, not stem loosening.
For young male patients or those with posttraumatic arthritis, counsel preoperatively about meaningfully higher long-term revision rates and consider cemented humeral fixation to maximize stem survivorship.
