Abstract
With the invention blocking systems for the medullary canal (,) of a tubular bone (,) are shown which have a blocking element (,) in order to hold bone cement (,) back from cemented prosthesis shafts (,). Because a deformable plug (,) which can be decomposed in the body is placed on between the blocking element (,) and the shaft end (,), which prevents an advance of liquid bone cement (,) in the capacity of a fill-in and which permits a penetration of the end (,) of the prosthesis shaft (,), a cement socket without a base arises which permits settling movements of the shaft in the hardened bone cement.
