I have made a finger cast in case of broken fingers. If you break a finger, you can place your hand through the sleeve and tape your finger into the splint for healing. How long a broken bones takes to heal in space is still unknown. We do know that bones begin to lose mass in microgravity, so broken bones may happen more often. Splints for hands would strengthen the fingers to help the astronauts keep up with their hard work.
