The efficacy of using Goretex fabric as a cast liner to improve skin care was evaluated. A prospective study was performed of 20 patients undergoing casting using Goretex underliners. At each cast change or at the end of casting, skin condition was evaluated. No change in any standard treatment protocol regarding cast changes was made because of the Goretex liner. Goretex fabric provided improved ease of care and prevented cast soiling. The breathability of the fabric was believed to be a benefit in decreasing skin irritation.
