摘要： Heat-recoverable orthopedic casts include a support which is maintained in an elastically deformed condition by a casting polymer, e.g. a polycaprolactone (PCL) or a side chain crystallizable polymer having a relatively low melting point. The cast is placed around the limb and is then heated. The casting polymer softens and the cast recovers around the limb. A liner is preferably placed between the cast and the limb, especially when the casting polymer is PCL or has a comparable or higher melting point. For high strength casts, the support is preferably an open-mesh knitted fabric which, when fully relaxed, contains at most 300 holes per inch2 (at most 45 holes per cm2). Such a fabric, when it is extensible to a maximum of 15 to 40 %, is also useful as casting tape which comprises a curable polymer casting composition, e.g. a water-curable polyurethane prepolymer. As illustrated in Figures 1 and 2, a stockinette liner (2) is preferably placed between the cast (1) and the limb as a thermal barrier. A reinforcing component may be used to strengthen the recovered cast. Suitable reinforcing components include (A) polyurethane precursors which are applied to the cast before or after recovery, and are polymerized during or after recovery, and (B) thermoplastic materials which are applied hot to the recovered cast. Casts made in this way can be divided to make splints which can be easily removed and replaced.

摘要： 2134219 9321967 PCTABS00027 Orthopedic casts which comprise a casting polymer of melting point Tm which is preferably from 40 to 60 ·C. The casting polymer is preferably coated onto an elastically deformed fabric, so that the cast recovers when heated to a temperature above Tm. The cast preferably has an air flow permeability of 10 to 35 % resulting from the presence of apertures of area 0.01 to 0.08 cm2, so that it can be rapidly heated by means of a hot air gun. Preferred casting polymers comprise a side chain crystallizable (SCC) polymer, particularly one containing units derived from styrene or another high Tg monomer. The addition of certain other polymers, e.g. an ethylene/vinyl acetate copolymer, and/or certain inorganic fillers, e.g. calcium carbonate, wollastonite and talc, results in improved balance of tensile strength and elongation.
