UHP & Spherical UHP

UHP

The UHP has been designed to treat disorders of the distal radio-ulnar joint (DRUJ).

It is used to treat primary osteoarthritis, post-traumatic osteoarthritis, rheumatoid arthritis, tumors and salvage of Darrach, Bowers, and Sauve-Kapandji.

ADVANTAGES 

  • It restores pain-free forearm rotation at the same time as any length discrepancy is corrected.
  • Stability is achieved by means of a simple soft tissue repair which is combined with a reconstruction of the triangular fibro-cartilage complex. (TFCC)
  • Allows a free range of flexion, extension, ulnar deviation and radial deviation at the ulnocarpal joint.
  • Different sized stems and heads.

Spherical UHP

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.

ADVANTAGES

  • 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.
