- a first portion designed to be fixed to a corresponding bone bed, said first portion including
- a neck having a threaded cavity, the threaded cavity having an opening and an opposing end portion;
- and
- a hole formed in the first portion and communicating with the threaded cavity for injection of cement therethrough;
