• Documents the early mechanical failure rates of a constrained shoulder prosthesis and shows how design modification reduced material failures substantially (12 of 22 vs. 2 of 21 shoulders). • Illustrates a built-in safety feature—controlled dislocation under excessive torque—as a design strategy to protect glenoid fixation, relevant to understanding constrained implant mechanics. • Provides historical context for the evolution of shoulder arthroplasty design, useful for trainees studying how constrained prostheses fell out of favor relative to later unconstrained designs.
