The Arcsplint™ helps to stop hyperextension, bending too far backwards, at the MCP knuckle joint. This splint cannot be worn on the thumb. Hyperextension at the MCP joint may be caused by Ehlers Danlos Syndrome.

Please select your ring size. Please note: you will be selecting a ring size, NOT cm/mm or inches. If you don't know your sizes, please use a ring sizer or multisizer to find your sizes. If you don't have a ring sizer already, we have them available here or feel free to purchase one elsewhere to take your measurements. A lot of times, a jeweler will help you find your ring sizes as well.
