A thumb spica splint is a specialized orthopedic brace designed to immobilize the thumb joints while maintaining the wrist in a functional, neutral position. It is primarily used for managing De Quervain’s tenosynovitis, thumb sprains (e.g., Gamekeeper’s thumb), and arthritis of the first metacarpal joint.
General Specifications (2026)
- Intended Use: Specifically designed to restrict movement of the Carpometacarpal (CMC) and Metacarpophalangeal (MCP) joints without inhibiting the movement of the other four fingers.
Key Features & Adjustability
- Closure System: Uses multiple hook-and-loop (Velcro) straps—typically one at the thumb and one or two at the wrist—for easy, one-handed application and customized compression.
- Open-Palm Design: Many 2026 clinical models feature an open-palm layout to improve sensory perception and allow for the handling of everyday objects.
- Malleability: The metal support is designed to be bendable, allowing users to obtain a customized fit for maximum stability.
