Cast21

Cast21 is a Chicago company that makes an alternative to the plaster and fibreglass cast: an open lattice net that slides over the limb and is filled with a fast-curing resin, hardening in minutes. The device is waterproof, breathable and lightweight, is applied in about three minutes and needs no cast saw to be taken off again.

The company works with orthopaedics, sports medicine, paediatrics, family medicine and urgent care, and its immobilisation net is FDA listed. Founded by engineering graduates of the University of Illinois and led by CEO Ashley S. H. Moy, Cast21 develops and tests its products from Chicago, and reports that the system releases significantly less isocyanate than traditional fibreglass casting.
