Summary of problem & solution:

Every year hospitals around the United States see collectively 6-7 million bone fractures. The typical treatment provided for this type of injury is a cast made of plaster-of-paris bandages. These orthopedic casts stabilize bone injuries until the bone is completely healed. However, there are numerous downsides to this type of cast: it has a long application time, it cannot get wet, and it can cause skin and health complications. FastCast overcomes these problems: it’s easy to apply and remove, waterproof, allows visualization and breathability of the skin, and is applicable to any extremity. The cast uses a new “particle jamming” technique where the chamber is filled with biocompatible particles that are jammed together when the chamber is placed under negative pressure. The change in pressure creates immediate stabilization for the bone, making application possible in less than two minutes compared to the 30-60 minutes it takes for a plaster cast. FastCast will improve patient experience and save cost and time.
