Biomet Bio-Modular Choice Shoulder System

Biomet Bio Modular with Offset Head  


This system has a unique extraction tool that fits into the Morse Taper of the humeral component.  Use an instrument such as the Kocker clamp to advance the screw into the device so that expands and locks into the hole (finger tightness is not enough).  Then attach the Biomet slap hammer and slap away.


The head can be removed with the Biomet pickle which is in a different (humeral head box) box than the stem extractor.  The DePuy Pickle fork for the pre Advantage heads seems to also work fine for head separation.

Biomet Integrated Shoulder System

  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The Biomet Integrated Shoulder System includes the Atlas Modular line as well as the Neer humeral components originally made by Kirschner Medical Corporation which as been bought out by Biomet.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

Atlas-C - Modular
