FRACTURE SHOULDER SYSTEM

Evidence-Based Innovation
for the Complexities of PHFs

Address What Others Overlook for Fracture Repair

The Catalyst Fracture Shoulder System addresses the unique challenges of managing proximal humeral fractures (PHFs). Unlike traditional reverse for fracture arthroplasty systems, it prioritizes tuberosity fixation and healing – key factors shown to enable improved outcomes – while delivering post-operative stability and surgical efficiency. The patented stem design promotes simplified tuberosity management and allows for uncemented diaphyseal fixation even in the presence of osteoporotic bone.

CATALYST FRACTURE SYSTEM FEATURES + BENEFITS:

TUBEROSITY-SPECIFIC FOSSA

Only stem with dedicated cavities for both tuberosities – promoting better tuberosity healing rates and improved functional outcomes compared to traditional reverse systems¹

PATENTED TUBEROSITY RETENTION RAILS²

Multi-directional tuberosity capture and suture versatility, and stem-based repair techniques enhance construct stability with higher load to failure and reduced cyclic displacement than non stem-based techniques^{3, 4}

135° ANATOMIC NECK SHAFT ANGLE

Promotes anatomic tuberosity positioning and superior healing rates and stability compared to 145° and 155° angles^{5, 6}

PRESS-FIT DIAPHYSEAL FIXATION

Uncemented fixation eliminates the need for cement or screws – saving time, reducing complications, and promoting better tuberosity healing, with cemented options available when needed⁷

COMPATIBLE ACROSS CONFIGURATIONS

Compatibility with reverse glenospheres and baseplates in standard, augmented, and lateralized configurations
