Stryker Solar

Styker Solar     Not Bony Ingrowth Neck  

These have a similar appearance to Biomet Bio-Modular and DePuy Global prostheses.  Note anterior superior rim, pointy distal end and head that would make an asymmetrical sphere if completed. 


This system has a special extraction device and must be specifically requested from Stryker during any revision case.  Without the extraction device, you will need to use a bone tape and a mallet to bang on the rim under the neck to remove the humeral prosthesis.


Compared to DePuy Global systems, they lack the medial ridge present on Global prostheses.


Compared to Biomet Bio-Modular systems, they lack the distinct tapered neck for the Morse taper on the superior portion of the humeral stem.


Note distinctive pancaked or rounded off heads often seen with these systems.

Stryker Dual Offset Head may or may not be used Note that Solar Heads are Rounded Off

BiPolar Head on Stryker Solar Stem

Styker Solar    

It can be difficult to differentiate the Biomet Bio-Modular Bipolar from a Stryker Bipolar system.  The Stryker may have a pointed distal end and a flat surface at the base of the male Morse taper.  The Biomet Bio-Modular should have a tapered up ridge at the base of the female Morse taper and often has a distinctively enlarged neck with a boney ingrowth structure. 




Stryker ReUnion Fracture System


Note superior medial hole for bone growth.
