Neoprene Thumb Splint

The Neoprene Thumb Splint is a thumb spica stabilizer designed to do what a simple elastic strap can’t: provide structured immobilization where it’s needed, while leaving your other fingers completely free to function. Worn around the hand and thumb, this breathable neoprene brace features a removable aluminum stay that restricts movement at the CMC (carpometacarpal) and MCP (metacarpophalangeal) joints—the exact spots where arthritis, tendonitis, and repetitive strain take their toll.

How It Works

The Neoprene Thumb Splint works through three mechanisms:

  • Immobilization– The aluminum stay holds the thumb in a functional, abducted position, preventing painful movements that aggravate the injured joint
  • Compression– The neoprene material delivers gentle, even pressure that helps reduce swelling and provides proprioceptive feedback (your brain's awareness of where your thumb is in space)
  • Heat retention– Neoprene traps body heat, which increases blood circulation to the injured area, promoting tissue healing and reducing stiffness
