About this product

Division: Shoulder Reconstruction
Category: Shoulder Reconstruction

GLOBAL® STEPTECH® APG Shoulder System builds on the clinical history of the GLOBAL® Shoulder Anchor Peg Glenoid by incorporating proven design elements, and PREMIERON® X-Linked Polyethylene to create a technologically advanced glenoid implant.

The novel GLOBAL STEPTECH APG Glenoid Component has been designed to correct excessive retroversion caused by posterior glenoid bone loss, to closely recreate the original glenohumeral joint line, and to minimize the removal of healthy bone. The prosthesis incorporates a proprietary step technology design with an anterior backside surface that is spherical and a posterior backside surface that is conical to effectively counteract posterior loading. The amount of correction is managed by the height (+3, + 5, or +7mm) of the posterior step built into the component.  All of these features work together to decrease the shear stresses at the bone/implant and bone/cement interfaces, thereby increasing implant stability.

GLOBAL STEPTECH APG Implants may potentially:

  • Minimize the need for glenoid bone graft to correct asymmetrical wear
  • Reduce the surgical time needed to correct asymmetrical wear using bone graft
  • Reduce the extent of the high side reaming, and the resulting loss of healthy bone and joint medialization
GLOBAL STEPTECH APG Shoulder System with built-in posterior step

Indications for Use

The  GLOBAL® STEPTECH®Anchor Peg Glenoid System is intended for use in total shoulder replacement surgery for patients suffering from:

  1. A severely painful and/or disabled joint resulting from osteoarthritis, traumatic arthritis or rheumatoid arthritis.
  2. Fracture-dislocations of the proximal humerus where the articular surface is severely communited, separated from its blood supply, or where the surgeon's experience indicates that alternative methods of treatment are unsatisfactory.
  3. Other difficult clinical problems where shoulder arthrodesis or resection arthroplasty are not acceptable (e.g. revision of a failed primary component).

Glenoid components are intended for cemented use only.
