Cast21 is introducing a medical cast for treating broken bones to increase patient comfort and decrease medical complications. Current casts completely cover the break site in a non-waterproof material, trapping dirt, sweat, and moisture on the patient’s skin with no possibility of washing the affected area. In addition, the closed design of the cast prevents physicians from visualizing the break site and monitoring any wound healing processes. Our product is completely waterproof, giving patients the freedom to shower, and its open design allows enables doctors to see the break site and dress accompanying wounds. Furthermore, Cast21’s patent pending, adaptable-fit technology means that physicians do not have to custom-make each cast for their patients. The casting supplies market in North America alone is over $312MM, and we can service $309MM of it with our arm and leg casts.
