Finally a shoulder arthroplasty system
as precise as you are.
Historically, challenges with shoulder replacement surgery include overstuffing the joint, difficulty accessing the glenoid, and inconsistent implant placement. With Catalyst, all that is in the past.
The Catalyst CSR is a single-tray shoulder arthroplasty system containing a non-spherical humeral implant for consistent anatomic joint line restoration, and specialized glenoid instrumentation with a revolutionized implant design for a less invasive approach. Surgeons currently using the Catalyst CSR describe the following key benefits:
Our non-spherical humeral implant is engineered for anatomic precision and motion.²
The implant shape coupled with the Catalyst CSR™ surgical technique
allows the bone removed during humeral preparation to be replaced precisely with the implant.
Designed as a total system with components that work in concert with each other, the CSR requires minimal bone resection
and also includes innovative anchoring elements that allow for healthy bone preservation.
Intelligent instrumentation aids with consistent implant placement and joint line restoration,
thus addressing both overstuffing and suboptimal shoulder kinematics – which continue to be
two of the biggest challenges faced while performing shoulder arthroplasty.
Indications for use:
The Catalyst CSR Shoulder System is indicated for use in skeletally mature individuals with degenerative diseases of the glenohumeral joint where hemi- or total shoulder arthroplasty is determined by the surgeon to be the preferred method of treatment. The Catalyst CSR Shoulder System is intended for use in patients with the following conditions where the humeral head, neck and glenoid vault are of sufficient bone stock and the rotator cuff is intact or reconstructable.
• Avascular Necrosis
• Rheumatoid Arthritis
• Post-traumatic Arthritis
• Correction of functional deformity
“I set out to design a less invasive approach to shoulder replacement surgery
that would better restore the native shoulder motion for our patients.”
