US Patent 7189264 Limb with modular prosthetic components

The present invention relates to a system with modular components for forming a prosthetic limb, wherein the effective length of the limb is adjustable to accommodate changing needs of a particular person. Several modular components are provided, including sleeve and spacer modules. Each sleeve module has a body with a selected length and has two opposed ends that are internally threaded. Each spacer module has a body of a selected length and has two opposed ends that are externally threaded. The modules are usable with existing prosthetic components have respective mating ends. The modules are twistable with respect to each other, which enables the effective length of the prosthetic limb to be adjusted. Further, the modules can be interchanged with modules having a different length, which enables large adjustment capabilities. A fully custom fitted prosthetic limb is therefore achievable without the need to custom make a single component.
