This prosthesis is very similar to the Neer prostheses but the anterior fin's inferior edge is not lower than the inferior edge of the dorsal fin. Note flattened underside of head with sharp edge. Also note pointed tip of stem commonly found on Xryas of Cofield prostheses.

Monoblock and modular total shoulder arthroplasty for osteoarthritis |
The hole in ventral fin distinguishes the Cofield II it from a Neer or Zimmer BF prosthesis.
Note - hole and fin configurations are very similar to the Zimmer Total Shoulder II monoblock system. The Cofield differs in that it has a pointed distal stem, a ridge/rim under the head and often has a notch/space under the head just superior to dorsal fin. The inferior edge of the ventral fin in the Cofield 2 isn't more inferior than the inferior edge of the dorsal fin as it is in the Zimmer Total Shoulder II. Except for the hole in the ventral find, the Zimmer Total Shoulder 2 has a ventral fin more similar in shape to that of a Neer 2 prosthesis.
