Report on Pott’s disease, or caries of the spine; treated by extension, and the plaster of Paris bandage.

Sayre was the first to use plaster of Paris as a support for the spinal column in scoliosis and Pott’s disease. His name is eponymically linked with Sayre’s jacket, a plaster of Paris jacket applied while the patient is suspended by the head and axillae, and with Sayre’s suspension apparatus, a tripod derrick with rope and pulley for head traction during the application of a plaster of Paris jacket.
