An orthopaedic support or product is formed of a doubleknit type fabric material with spaced interwoven layers formed of high strength materials and an open-work matrix of filaments or threads interconnecting the layers. The fabric may be impregnated with water hardenable urethane. Hydroxy propyl methyl-cellulose (HPMC) will also be applied to the doubleknit type material or other casting fabric in sufficient amount to reduce the stickiness of the water hardenable urethane. The HPMC may be mixed in with the water hardenable urethane prior to impregnation, or may be applied to at least one of the outer surfaces of the doubleknit type material. The orthopaedic support or product is packaged in a water-vapor impermeable package; and is opened and water is supplied to the fabric when it is applied to the part of the anatomy requiring support. The fabric may be included in a soft goods support including a water distribution network and straps to hold the support in place.

[ What is claimed is:] [1.] An orthopaedic method comprising the steps of:a) forming an integral double layer fabric having spaced interwoven layers formed of high strength filaments and an open-work matrix of filaments interconnecting said layers;b) impregnating said fabric with a water-hardenable urethane under low humidity conditions, while retaining the configuration of said matrix permeable to receive water;c) applying hydroxy propyl methyl cellulose (HPMC) to said fabric;d) packaging said impregnated fabric in a water vapor impermeable package;e) subsequently opening said package;f) supplying water to said open-work matrix following opening of said package to rapidly wet said water-hardenable urethane and said HPMC; andg) locating the impregnated double layer fabric adjacent the injured part of the anatomy so that said impregnated fabric conforms to the configuration of the anatomy;whereby (1) the open-work matrix of said double layer fabric facilitates rapid and uniform impregnation by the water-hardenable urethane, and uniform penetration of the water, and also provides firm support resulting from the hardening of the water-hardenable urethane in the open-work matrix; (2) the HPMC reduces the stickiness of the urethane when wetted; (3) and smooth outer surfaces are produced following hardening.
