Joint conformity in shoulder prostheses: In-vitro measurement of interface micromotions in a metal-backed glenoid implant

The purpose of this study was to evaluate the influence of glenohumeral conformity on interface micromotions in a metal backed glenoid implant. A force controlled experiment was performed in which a metal backed glenoid component with various PE inlay radii was subjected to a simulated joint reaction force. Local interface micromotions, rim...
