Abstract
The reinforcement is formed of a peg from which a plurality of flaps extend with slots formed between adjacent flaps. The flaps serve to separate a bone cement bed within the interior of the reinforcement from a layer of a compacted spongy tissue externally of the reinforcement. The slots between the flaps extend over the entire height of the reinforcement and permit substantial spreading or widening of the flaps radially in order to adapt to the individual operation cavity and to anchoring stems of different cross-sectional sizes and shapes.
