The STS Company has announced the addition of a new molding sock to its family of casting materials. The Trans-Tibial sock, developed as a part of a postoperative rigid dressing system introduced recently in Australia, is suited for obtaining a negative model of a below-knee amputated residual limb. The sock features a newly designed knit and a polyurethane resin incorporated into the sock that results in a firmer and stronger negative mold. The molding socks are donut rolled for easy application and will not shorten or deform the limb when applied. Available in a range of sizes.
