CATALYST

STEMMED ANATOMIC SHOULDER

STREAMLINED, VERSATILE, ANATOMIC

THE CATALYST STEMMED ANATOMIC SHOULDER SYSTEM

THE FIRST STEMMED TSA WITH AN ELLIPTICAL HEAD

Allows surgeons to convert from an anatomic hemi-arthroplasty to a reverse humerus (and vice versa) without the need to remove the stem.

COMPATIBLE WITH 3-PEG GLENOID AND CATALYST HUMERAL STEM

Compatible with the 3-Peg Glenoid and utilizes the Catalyst Humeral Stem for easy conversion to a Reverse construct.

ELLIPSOID HUMERAL HEAD

  • Optimized AP/SI ratio based on leading clinical anatomic studies1

LOCKING SCREW

  • Fixates adapter to stem
  • Size specific (included with adapter)

ADAPTER

  • Concentric and Offset designs with 2 height options available
  • Works with both 36mm and 41mm diameter stems

ADAPTERS

24 total Humeral Head/Adapter combinations provide a variety of options to address all surgical plans.

CONCENTRIC ADAPTER

  • +0 and +3 height options

+2.5MM OFFSET ADAPTER

  • +0 and +3 height options
  • 12 locking positions at 30-degree increments

ELLIPSOID HUMERAL HEADS

  • Laser markings to indicate superior-inferior orientation
  • Six head sizes available to cover all patient anatomies
  • Morse Taper lock connection to adapter

Laser marks

3-PEG GLENOID COMPATIBILITY

Three glenoid sizes available in both standard and 10-degree augmented configurations

  • Angled pegs allow for oblique approach
  • Tapered-bearing rim for inherent stability
  • Pegs designed for immediate interference fit fixation

3-Peg Glenoid

Augmented 3-Peg Glenoid

CATALYST HUMERAL STEMS
