Abstract
An orthopaedic support (50) 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 hardened 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 hardened urethane. The HPMC may be mixed in with the water surfaces of the doubleknit type material. The orthopaedic support (50) or product is packaged in a water-vapor impermeable package; and is opened. 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 (74) to hold the support in place.
