Adjustable thigh prosthesis for compensation of volume variations and imposing femur adduction

Abstract

A thigh prosthesis with a shell-type sleeve and a plurality of cheeks adjustable sleeve-inward and sleeve-outward arranged on the sleeve wall, is characterized in that such cheeks are elongated and are disposed in the dorso-lateral zone in connection to the side of the thigh bone, extending from proximal to distal, and in approximately round form in the medial distal zone. The stump zones concerned have proved especially well suited for the initiation of lateral forces and for volume reductions possibly sought or to be compensated therewith on the stump. Moreover, by abduction, the abnormal position of the thigh bone frequently encountered in thigh-amputated patients can be corrected. Preferably the cheeks are formed by inflatable cushions which, in the case of two-sleeve prostheses, are advantageously arranged between an outer sleeve and an inner sleeve. A further such cushion may be disposed within the sleeve in the stump end zone.
