enkelprothesen

Enkelprothesen are artificial devices designed to replace the ankle joint or parts of the lower leg around the ankle after amputation or congenital deficiency. They are used to restore a functional gait, provide stability, and enable activities of daily living. Enkelprothesen can be fitted after an ankle disarticulation, severe trauma, tumors, or problematic ankle joint disease, as well as after certain partial foot amputations.

The basic construction of an enkelprothese typically includes a socket to fit over the residual limb, a pylon or structural leg component, and a prosthetic foot with an ankle mechanism. Designs vary from simple mechanical hinges to more advanced hydraulic or pneumatic ankles that adapt to walking speed and terrain. Modern options also include energy-storing feet made from carbon fiber and microprocessor-controlled ankles that adjust ankle stiffness and timing in real time. In some cases, partial foot prostheses or toe and ray prostheses are used to replace specific forefoot structures.

Fitting and rehabilitation involve a multidisciplinary approach, including assessment of limb length and tissue condition, meticulous socket fabrication, proper alignment, and gait training. Patients require education on wear-time, skin inspection, and maintenance of components. Regular follow-up is needed to address changes in fit, wear, or activity level, and to adjust the device for comfort and function.

Outcomes with enkelprothesen range from improved mobility and independence to challenges such as skin irritation, socket breakdown, or higher costs. Advances in materials, socket design, and adaptive ankle mechanisms continually enhance comfort and walking performance.
