Helixsplint™ MCP+IP Hyperextension

The Helixsplint™ helps stop hyperextension, bending too far backwards, at the MCP and IP  thumb joints. Hyperextension can be caused by injury, Ehlers Danlos Syndrome (EDS), or other condition. Includes a 925 Sterling Silver flush curb chain bracelet for optimal fit and comfort.  


  • MCP and IP hyperextension support

Helixsplint™ MCP+IP Hyperextension

Wrist Size
  • Please find the size below the end thumb joint (proximal IP joint) and above the end thumb joint (distal IP joint).

    When measuring your wrist size, please use a measuring tape and measure just as you would for a bracelet. Simply measure around the wrist, do not add length.

    It is HIGHLY recommended to use a ring sizer or multisizer to find your sizes. If you don't have a ring sizer already, I have sizers 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.

    If you have a sewing-type "fabric" tailor's tape measure, that can be used. Centimeters/millimeters are more accurate than inches, and a more narrow/skinny tape measure will be even more accurate. PLEASE NOTE: If using a tape measure, please allow for size discrepancy, usually on the large size. Tape measures can be off by as much as 3 ring sizes if done with too wide of a tape measure or in inches. Again, a ring sizer or multisizer is the best method. Once you have your cm/mm measurement, it can be converted into a US ring size at ringsizes.co
