A Roentgenological Study of the Stump—Socket Contact and Skeletal Displacement in the PTB-Suction Prosthesis

Abstract

The PTB-suction prosthesis has been studied by a roentgenological technique. There is complete contact between the skin of the stump and the plastic inner surface of the socket. The movement of the stump in the socket is minimal. The displacement of the skeletal stump is reduced to half in the PTB-suction prosthesis, compared with the strap-suspended PTB prosthesis. As a result, the stability between stump and socket is increased, provided that the stump is sufficiently long. Skin sores are avoided. The prosthesis, when adequately fitted, guarantees a good circulation within the stump and a cosmetically favourable fit with a feeling of walking with “a normal leg”.
