The Collarsplint™ helps to stop hyperextension along with instability at the mid finger joint (PIP joint) or end thumb joint (IP joint) or end finger joint (DIP joint). Hyperextension can be caused by injury to the joint, Ehlers Danlos Syndrome (EDS), Benign Joint Hypermobility Syndrome (BJHS), or other condition.
- joint injury, resulting in the finger or thumb bending too far backwards
- Ehlers Danlos Syndrome (EDS)
- benign joint hypermobility syndrome (BJHS)
- instability at the PIP, DIP or IP joints
- sideways curvature
- mild deviation
Collarsplint™ Hypermobility or Instability
Please find the size above and below the affected joint. 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.
