3.5mm ARCIS™ by UnifiMI® Fastener S/T

ARCIS™ bone fastener screws represent the next generation in veterinary orthopaedic fixation technology. 

Designed with precision engineering inspired by aerospace applications and backed by years of proven performance in human medicine, these revolutionary fasteners deliver superior stability, immediate load-bearing capability, and exceptional resistance to displacement—even in the most challenging clinical conditions.

Advanced Mechanical Integration Technology

The ARCIS difference lies in its proprietary UnifiMI (Unified Mechanical Integration) technology, featuring a unique thread geometry that circumferentially interlocks with bone. Unlike conventional screws, ARCIS fasteners:

• Preserve the natural architecture and biology of bone
• Instantly interlock implant to bone circumferentially
• Enable immediate and long-term load sharing between implant and bone

Available Options

• 2.7mm ARCIS Fasteners: Ideal for small animal applications and fracture fixation in compact bone areas
• 3.5mm ARCIS Fasteners: Perfect for medium to large animal applications requiring greater structural support

How ARCIS Technology Works

1. Precision Insertion with Minimal Bone Impact
The self-tapping thread geometry cleanly prepares and preserves bone during insertion.

2. Immediate Mechanical Stability
Circumferential interlocking eliminates the need for time-dependent biological integration.

3. Instant Load Sharing
Provides stable implant support while preserving natural bone biology. 

Clinical Applications

ARCIS bone fastener screws excel in various veterinary orthopaedic procedures:

• Fracture repair and stabilisation
• Osteotomies
• Joint surgery
• TPLO use
• Challenging fixation cases with compromised bone quality

Why Choose ARCIS?

The unique UnifiMI thread interface entraps and contains bone within the thread form, creating a mechanical interlock that delivers immediate stability without waiting for biological integration. This revolutionary approach enables faster recovery times, improved clinical outcomes, and greater confidence in your surgical interventions.
