Stable Thumb Splint with PVX

Use the SilverRing™ Stable Thumb Splint to reduce hyperextension of the MCP joint. The PVX (proximal volar extension) supports underneath the head of the MCP metacarpal to block the subluxation. There are two PVX styles to choose from: The ‘U’ shaped PVX distributes pressure along the length of the U and leaves an opening inside the U if direct pressure on the head of the metacarpal is uncomfortable. The Spoon shaped PVX places more direct pressure with a curved pad and is much more adjustable since it attaches with one bar. The Spoon shaped PVX can easily be twisted or bent left/right. Both PVXs are designed to be equally strong. If a PVX breaks outside our warranty please contact us to discuss repairing or replacing the splint. Use instead of the SilverRing Thumb MCP Splint when the thumb is adducted, subluxed at the CMC joint, has a tight web space or limited passive MCP motion. Use Stable Thumb w/ PVX if problems develop following CMC arthroplasty. There are 3 different dorsal plate options to choose from: Standard, Long and 3D.  The Standard dorsal plate is better for smaller hands and/or to avoid putting pressure on areas near the CMC joint. The Long plate is better for larger hands or when more leverage may be helpful. The 3D plate is the one design which is right or left hand specific and is better when MCP joint is more enlarged. The 3D plate wraps around the MCP joint which some find more comfortable. A bracelet is included with this splint because it is necessary as a counter force. There are 3 clasp options: Lobster clasp, ‘S’ Hook and Magnetic Clasp. The Magnetic clasp costs extra but is the best options for people lacking fine motor dexterity or who have difficulty pinching.
