| Re: Thumb Injury, Graspability Loss...
If you can actively move it at all joints, then the tendons are intact. Does it feel "loose" or floppy when you try to move the joints to the sides (dont push too hard!) You may have simply sprained/ stretched one of the collateral ligaments, or you may have torn it ( sometimes called skier's thumb or gameskeepers thumb). If your thumb MCP (knuckle) is lax when you push your finger away from the webspace, see a doctor. A simple sprain only requires ice and rest, however a fully torn ligament requires casting or surgery.
