Hầu hết hệ thống treo hiện tại, đầu gối, bàn chân / mắt cá chân hội đồng, giảm xóc sử dụng endoskeletal và xây dựng Nhấn mạnh đó liên hệ với tổng số và phân bố trọng lượng giữa các cấu trúc xương và mô mềm. | Componentry for Lower Extremity Prostheses nm Abstract Karen Friel PT DHS Prosthetic components for both transtibial and transfemoral amputations are available for patients of every level of ambulation. Most current suspension systems knees foot ankle assemblies and shock absorbers use endoskeletal construction that emphasizes total contact and weight distribution between bony structures and soft tissues. Different components offer varying benefits to energy expenditure activity level balance and proprioception. Less dynamic ambulators may use fixed-cadence knees and non-dynamic response feet higher functioning walkers benefit from dynamic response feet and variable-cadence knees. In addition specific considerations must be kept in mind when fitting a patient with peripheral vascular disease or diabetes.

With the advent of new materials designs and technologic advances the field of lower extremity prostheses has expanded dramatically. Prosthetic components have a significant impact on functional performance. The choice of components varies depending on a patient s functional level this is especially true regarding the specific needs of patients with amputation secondary to peripheral vascular disease or diabetes. These critical needs include protecting the sound limb considering abnormal and excessive forces on the residual limb and factoring in the metabolic costs of ambulation.
