Although minor improvements have been made over the years, casts have remained essentially the same: a combination of cloth and plaster that, once hardened, encases a limb at 360 degrees in order to immobilize that limb and give the bone time to heal.

Two main problems arise from this method. Firstly, encasement leads to little breathability, trapping sweat, bacteria, and heat, which often leads to discomfort, itchiness, odor, and greater chances of infection and soft tissue damage.

Secondly, traditional casts are permeable. Because of this, patients cannot wash affected areas since doing so will damage the structure of the cast. As many clinicians know, casts often end up getting wet anyway which leads to more recasts and more office visits.

Cast21 solves both of these problems and provides doctors greater visibility of the fractured area. Made of specialized polymers, our patent-pending technology meets the needs of today’s lifestyles. Our device’s strong, netted structure allows light and air to reach the affected area. Patients can wash the skin around the affected area. They can shower, exercise and even swim. Because less sweat and bacteria are getting lodged close to the skin, the chance of infection and soft tissue damage is reduced significantly. Water is no longer the enemy of the cast but a welcome ally in health and healing.

We have made it our mission to provide doctors and patients with a better cast that is effective, affordable, and actionable. We understand the day to day demands of orthopedic surgeons and their teams and have developed our technology to work in accord with standard operating practices. Cast21 requires no expensive equipment and application takes approximately 3-10 minutes, about the same time it takes to wrap a limb in padding and the conventional plaster or fiberglass casting.

How it Works

Our revolutionary fracture orthotic takes its design cues from structures you see every day. Bridges are often supported by trusses or cables. Buildings are held up by support beams. We use these engineering examples as our blueprint, combined with the braided structure of a helically wound braid i.e. the “Chinese finger trap.” This braided structure strengthens and reduces in circumference when it is stretched, distributing force evenly around the limb. Once hardened, the resulting structure is designed to protect the fractured bone beneath and enable it to heal with minimal encasement and zero swathing.

Cast21Cast21 comes in different sizes. Patients are fitted for the cast and pin is pulled from the soft, malleable, liquid-filled sleeve. Next, the sleeve is shaken like a glow stick and is slid onto the fractured arm or leg. This solution will harden in less than ten minutes. Surgeons and their support technicians keep the limb stable and in proper alignment while the cast firms and adheres to the area. Once hardened, the device is set. No splint, padding or other materials are required and patients can return to their daily activities, including workouts, as advised by their doctor.
