Designed for the treatment of common finger injuries where the injury requires either DIP or PIP joint extension.
Zero-Cast Mx provides visible hyperextension of the distal interphalangeal joint (DIP) when used for the common Mallet Finger Injury.
Mallet finger (or mallet toe) is a common injury that occurs when the tendon responsible for straightening the tip of the finger or toe is torn or pulls away from the bone. It often results from a sudden impact during sports such as netball, cricket, basketball, or volleyball, leaving the fingertip bent and unable to straighten.
Fingertip injuries can occur from crushing accidents, fingers caught in doors, hammer strikes, or other direct trauma. These injuries may involve the skin, nail bed, bone, tendons, and soft tissue (pulp) of the fingertip.

Fingertip injuries can bring your daily routine to a standstill. Because they are challenging to manage, they often drag out your recovery and make simple, everyday tasks incredibly frustrating.
For mallet finger injuries and fingertip fractures, proper splinting is absolutely essential. By immobilizing the finger in the precise healing position, you allow the torn tendon or fractured bone to knit back together correctly—restoring full function and preventing permanent deformity.
The Zero-Cast F1x™ Difference: Traditional splints completely isolate your hand, making it nearly impossible to text, type, or swipe. Zero-Cast F1x™ bridges the gap between clinical care and modern life. It delivers rigid, medical-grade support to protect your injury while keeping the tip exposed just enough to allow full access to smartphones and touchscreen devices.

The patented design of Zero-Cast F1x™ effectively corrects deformities and accelerates natural healing by eliminating direct pressure on injured tissue.
The Mechanism of Action
Customized Compression: The system features two anatomically contoured plates connected by an adjustable ratchet mechanism. When the plates are compressed, they gently correct the deformity with precision pressure tailored specifically to your finger's unique shape.
Predictable Results: This secure, engineered fit ensures consistent, predictable alignment throughout the recovery process.
Tailored for Function: Any excess length on the ratchet legs can be easily snapped off, keeping the device streamlined and completely functional.
Designed for Daily Life
Active Recovery, Zero InterruptionUnlike traditional bulky splints, Zero-Cast F1x™ is engineered to keep you connected and moving.
Touchscreen Compatible: The contoured plates leave the finger pulp entirely exposed, allowing for natural tactile feedback and uninterrupted smartphone or touchscreen usage.
Full Mobility: The ultra-low-profile design ensures your surrounding, uninjured fingers retain their full range of motion.
Correct deformities in just three simple steps with visible, reliable results.
