How to Make a Customized (and Removable) Wrist Cast
Thousands of years ago, ancient cultures (Egyptians, Greeks, Hindus) used wooden splints wrapped with linen to secure broken bones. Hardened casts started popping up in different forms around 30 AD, incorporating anything from wax and resin, to seashells and egg whites, to flour and animal fat in an effort stiffen the bandages and set the bone more reliably. The process evolved over centuries until we arrived at the plaster bricks we put on our broken bones today, which offer superior support and customized fit to provide the best environment for healing. But casts can invite a host of nasty skin issues, itchiness, staph infections, and dermatitis into your life. Not fun. A splint, on the other hand, is removable and less itchy. However, in order to secure the fracture, its straps must be very tight, meaning a lot of throbbing, aches, and general pressure. But leave it to a mathematician with a broken wrist and 3D Systems technology to experiment with a wrist cast/splint (a “clint” or a “splast”). His mission: to quickly blend optimal support with comfort and removability.
