Abstract

The present invention addresses the problem of improving the heat conductivity of an orthopedic fixing material comprising a resin material. An orthopedic fixing material is formed by using a base material that comprises a resin component and a heat conductive powder such as an aluminum powder. Owing to the use of the heat conductive powder, the heat conductivity of the orthopedic fixing material is improved. When an affected part is fixed with this orthopedic fixing material and then a cooling plaster or a heating plaster is applied thereon, the affected part can be treated in a cooled or heated state. When an aluminum powder with a relatively light weight is selected as the heat conductive powder, an increase in the weight of the orthopedic fixing material can be avoided.
