The Spherical Herbert Ulnar Head Prosthesis is used to restore ulnar continuity after failed Sauvé-Kapandji procedures, preventing further painful radioulnar impingement.


The operating technique allows the surgeon to retain and utilize the original arthrodesis of the radioulnar joint for increased stability of the new joint with which the spherical head articulates.




  • 3 different types of stems and heads.

  • The system can be used in cases of a severely shortened ulna.

  • Existing arthrodesis left intact.

  • Increased stability.

  • No cement required for anchoring the stem of the prosthesis in the ulna.

  • Promotes osteointegration.
