DePuy has produced several very popular shoulder systems.  The first was a monoblock system knowns as the HRP.  A second generation modular Global system was produced and the newer Global advantage modular system is currently in wide use.


DePuy had three models - the HRP, Global and Global Advantage

The HRP was a first generation monoblock design

The Global is a second generation Modular Design

The Global Advantage is also a second generation Modular Design



These first generation monoblock prostheses were actually made after the second generation modular DePuy Global.  Since the original DePuy Globals have such large exposed rims under their modular humeral heads, small heads mounted on these bodies leave the rim exposed and proud.  These protruding rims can cause open booking as it levered on the glenoid.


The later Global Advantage reduced the size of this rim and created a head with an overhang that covered the minimized rim, which makes the HRP prostheses less desirable than the newer prostheses.  The 44 and 48 Global Advantage head will not fit on the old Global bodies.

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.


Because of the large rim on the Global prostheses, you will not be able to put on the 44 and 48 Global Advantage heads because of the overhang in the new design.  Newer Global Advantage 52 heads have a close fit on the old Global stems and 56 heads fit fine.  The eccentric heads don't seem to work but a 56 18 just fits with about a millimeter of clearance.

DePuy Global Advantage

DePuy Global  


Here's a great view of a head/stem interface.  Note that the Global Advantage does not have a viewable gap between the body and head.  The medial (ventral) fin has a hole in it and the Global does not.  Note the size of the anterior rim - this is as big at it gets since it appears to be on the smallest sized stem (6mm).


Note Recessed notch on dorsal fin on Global Advantage.  This Notch is not present in DePuy Global or HRP.

DePuy Global Fracture

DePuy Global Fx  

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.

DePuy Global AP - Released February 12, 2007





Note lack of dorsal fin or holes in side fins.  This design allows for adjustment of neck angle in two planes.  An adapter is available to allow for fixed angle of the head.
