Shoulder Prostheses
Ever wanted to know what shoulder prosthesis you were looking at on an x-ray? Are you planning a big revision arthroplasty and need to know which vendor to call for part?
A good set of x-rays and the following images should help you identify most shoulder prostheses commonly used in the US.
1st generation prostheses (monoblock, non-modular):
Neer (3M)
Cofiels (Richards)
Fenlin (Zimmer)
2nd generation prostheses (modular):
Neer (3M)
Bio-Modular (Biomet)
Select Shoulder (intermedics Orthopedics, Inc.)
Global (DePuy)
3rd generation prostheses (modular and adaptable variable version,
offset and inclination):
Aequalis (Tornier)
Anatomical Shoulder System (Zimmer)
4th generation prostheses (modular and in situ adjustability):
Equinoxe (Exactech)
3D Univers
PROMOS modular components
Morse Taper
A Morse taper is used in many shoulder prostheses to allow for locking of modular heads, stems and in some cases stem extensions. This is not a universal system. For one, the male end of the taper may be on the head component or on the stem component. The width, depth and diameter of the Morse taper also differs between companies and prosthetic designs.
One design theory is that having the male taper on the stem decreases the amount of bending on the taper and decreases the chance of loosening.
Another design uses the taper on the head to make revisions, particularly with the glenoid, easier since the taper isn't poking out of the arm and into the glenoid when the head is removed.

  |
| Biomet Integrate Offset Head | Biomet Fracture |
The Biomet Integrated Shoulder System includes the Atlas Modular line as well as the Neer humeral components originally made by Kirschner Medical Corporation which as been bought out by Biomet.
The Neer II - a monoblock stem.
Kirschner II-C added proximal q porous coating.
Kirschner Modular II-C is identical to Kirschner II-C but with a modular head. These were made by a different company than the 3M Neer prostheses and are not designed to be interchangeable.
Kirschner/Biomet Modular II-CX are still available through Biomet.
Mod II Plus-C -
Atlas- Modular - choices in head thickness, proximal and distal stem diameters, stem lengths and proximal surface finish

DePuy Global
Note space between upper rim of stem and head. Also not how prominent the upper rim is compared to Global Advantage.
This prosthesis uses a "pickle fork" aka "tuning fork" head extractor to separate the head form the stem.
Stems may be double sized - with a smaller distal diameter than the proximal stem.

DePuy Global Fracture
The Depuy Global fracture stems are cobalt steel. It has a more prominent anterior rim than the Global Advantage stem. The dorsal fin has only one hole and the posterior lateral fins have three holes that are positioned more superiorly than the Global Advantage stems. In the fracture stem, the distance of the edge of the first hole from the superior edge of the posterior lateral fin is about the length of the diameter of the hole. The distance from the superior edge to the edge of the first hole in the posterior lateral fin of the Global Advantage is about 3 diameters of one of these holes.

A screw on the bock of the head (shown above - posterior of stem in left shoulders and anterior in right shoulders) may or may not be used in conjunction with locking of head onto stem. This would make head replacement alone more difficult in a revision surgery and require removal of entire unit, or some fancy drilling or hammering. The screw head accepts a small hex/Allen wrench. The Tornier set has a blue handled driver for this screw. The screw should be removed prior to trying to bang off the head. The head should come off with a bone tamp and a mallet.
The humeral prosthesis can be removed with a medieval appearing adjustable triple claw extractor on slide hammer that comes with the Tornier extractor set..
