Neer prosthesis

The foimdation that Neer laid for shoulder replacement can be seen today in many ways. The continued production and use of the 1973 version of his humeral component as the Neer II and the many other humeral and glenoid components based on this original design is testament to its stature in the surgical community. The basic concepts included in the Neer prosthesis such as all-polyethylene and metal-backed keeled glenoid components and wire...

In 1973, Dr. Neer also performed a TSR for the first time [24]. He used a cemented polyethylene glenoid component with his Neer humeral prosthesis that had been modified to more beneficially articulate with a glenoid component [24]. The polyethylene glenoid, an RCH-1000 device, was designed by Robert G. Averill, manufactured by Howmedica, and sterilized by ethylene oxide gas [8]. Between 1973 and 1982, Dr. Neer designed a number of glenoid components, both with and without metal backings [25].
