Abstract
The invention is directed to orthopedic casting tapes including an open mesh fibrous tape coated with a hardenable liquid resin, preferably a water activatable resin, that permits shaping and curing of the tape to provide a hardened cast. The fibrous tape is a knit tape is formed primarily or entirely of unbulked, continuous polymeric filaments and elastic filaments. A plurality of continuous filament courses extend generally transverse to the plurality of wales and are present in the fibrous tape in an amount of at least 15 courses per linear inch of tape, measured in a relaxed state. The wales are present in the fibrous tape in an amount sufficient to provide at least about 275 openings per square inch. The casting tape has an extensibility of at least about 5 percent. The orthopedic casting tapes of the invention cure rapidly despite their fine mesh/high mesh content structure and normally are set within 3-5 minutes following application. Hardened casts of five layers formed from the casting tapes of the invention typically have a 24 hour crush strength comparable to or greater than the strength of casts made from fiberglass casting tapes currently used in commerce.
