Abstract
A therapeutic traction system comprises two principal modules--a bandage-like traction band module for applying to a finger or other digit and a spring module. A minmum working combination consists of two traction band modules with a spring module connected between them so as to bias them apart. Traction band modules may vary in the number and orientation of connecting elements to which a spring module may be connected. Spring modules are elongated coil springs which, in use, are usually deflected into a bow form and, optionally, also torsionally deflected, to create the desired biasing force.
