[A brief history of the use of Gypsum in orthopedics].

Humans processed gypsum for their everyday use at least 7000 years ago. They have been using fixed limb methods for fracture treatment for nearly 5000 years. Hippocrates recognized the importance of the splint and the "roller bandage" for fracture treatment, and made the bandage hard by adding wax, pitch, lard or resin to the multi-layer cloth bandage, but not gypsum. Arabian physician El Zahrawi (936 -1013) also described a clay glue mixture, and flour and egg white as fracture fixation materials. From 970, Persian physician Muwafak used gypsum as the exclusive material for fracture fixation. The rudimentary form of modern plaster bandages was developed in the mid-19th century and spread widely after that, using methods from the Russian Pyrogov by soaking canvas in a gypsum slurry and Dutchman Massson wrapped gypsum powder in cotton cloth strips.
