Design evolution of the shoulder prosthesis

In 1993 Prof. Randelli from Italy started the design of an innovative shoulder replacement. By May 1994 The Randelli system was ready. It was uncemented, and was modular, meaning it could be assembled from a number of different parts, giving unprecedented flexibility to fit and reconstruct the normal anatomy of almost any situation.

In 1995 the new glenoid, or socket component, was introduced. It was also uncemented and had a modular plastic (polyethylene) insert which could be changed. If it wore out say in 15 years after surgery, it could be changed without having to remove the fixed components of the shoulder.

The end result was one of the most innovative and versatile shoulder replacement the world had ever seen.

But there are now new innervations which allow us to perform shoulder replacements for a very common problem, that of a CTA. For more information on CTA click here
