Abstract

A blank is described for producing a soft wall inside socket of a prosthesis having a pre-shaped side wall formed of a thermoplastic material, an inside liner and an outside sheathing. The blank forms a receiving space for receiving a shank stump and having an opening restricted by an edge of said side wall, for inserting the shank stump. For the purpose of adapting the height of said edge of the blank to the shank stump to be received, a slit-shaped recess runs along said edge and extends from the edge into the side wall by a predetermined depth (T). Preferably, the slit-shaped recess is arranged in the center of the side wall such that a double wall portion is formed with an inner wall adjacent to the inner liner and an outer wall adjacent to the outer sheathing, whereby the thickness of the inner wall essentially corresponds to the thickness of the outer wall.
