Signature™ ONE Surgical Planning

Software and Guides

Zimmer Biomet’s Signature™ ONE Surgical Planning System provides a 3-D image-based approach to preoperative visualization, surgical planning and patient specific guide creation.  Based on each patient’s unique anatomy, integrated with proprietary algorithms and known anatomical landmarks, Signature ONE offers a tailored approach to shoulder arthroplasty.

Signature ONE Planning


Beginning with a CT scan, Zimmer Biomet quickly provides back an initial surgical plan, combining surgeon surgical preferences and patient anatomical landmarks.  Adjustments can easily be made based a quick review of the surgical plan.  The software features all of Zimmer Biomet’s key shoulder arthroplasty systems including the Comprehensive™ Total, Reverse and Augmented options along with the Trabecular Metal Reverse Plus™ (TMR+) System and Alliance™ Glenoid (Pure Planning only)..

Surgical planning consists of several adjustable attributes based on the presenting indications and surgical goals including:

  • Backside contact and 3D measurement tools
  • Lateralization reference points to assist in preserving glenoid bone
  • Quick changes from non-augmented to augmented components for maximum bone preservation
  • Ability to visualize inferior Glenosphere offset for improved ROM
  • Central screw length visualization

Signature ONE Guides


Once the surgical plan is approved, guide creation begins and is provided for in-surgical use with several key supporting components:

  • Signature ONE Glenoid guide for accurate pin placement
  • Patient glenoid bone model for visual confirmation throughout the procedure
  • Depth control arm to assist is accurate glenoid depth reaming
  • Baseplate orientation guide and screw guide (TMR+ only)

The Signature ONE Guides add no additional steps to the surgical procedure and are placed on the glenoid to guide initial pin placement.  A secondary superior pin is also inserted that will accurately control ream depth.  The introduction of ream depth is unique to the system and highly important when wanting to achieve maximum bone preservation of the glenoid.

Signature ONE Planning and Guides allows the surgeon to achieve:

  • CONFIDENCE in understanding patient anatomy with high-quality 3D reconstruction and the ability to reproduce that plan to the patient
  • SIMPLICITY with easy to use guides and software interface
  • CONVENIENCE through on-line access with any computer or iPad® along with a surgical technique that fits intuitively within existing techniques.
